Weekend garden jobs, March 12th & 13th 2023

It’s a lovely long weekend, with perfect clear skies and cool, but sunny weather. I spent a day and a half in the garden – and there was a lot to do!

It’s the end of Summer and many of the seasonal plants are finished for the year. Eggplant, okra, capsicum, and chillies are still going strong, but it was not a great season for tomatoes in my garden, so I pulled almost all of them out.

Okra is my little experiment for the season – I tried and failed to germinate it twice in two different spots in my garden before it finally grew. It has slowly started to fruit, probably quite late in the season, but I am letting it continue for as long as I can. Yesterday I picked two – yep, two – whole pods. I sliced them up, washed them and dried them to reduce some of the famous okra sliminess, and threw them into a curry, where they dissolved into nothingness – so I cannot tell you how they tasted. I’m hoping for some more before the warm weather disappears completely.

I picked the rest of the green tomatoes off the bushes, with a plan to make green tomato pickle. As I did not want to go shopping for additional ingredients, I tried this recipe, which is for refrigerator pickles using green tomatoes instead of cucumbers. I played around with the recipe a bit, subbing sliced onion for the fennel bulb, adding some sliced green jalapeno (because, yum), and using whole coriander seeds instead of the fennel, because that’s what I had on hand. I ended up with four jars of green tomato pickles for use on burgers and sandwiches. If the tomatoes do not taste delicious, I have not wasted much except a bit of vinegar and my time, but if they are good I will have preserved fruit that would have gone to waste. I’ll let them mature for a couple of days, then will report back on the flavour.

After pulling the zucchini and tomatoes out, I dug over the beds and spread some dynamic lifter over the soil. I raked the soil to a lovely, crumbly fine tilth, ready for planting Autumn veggies – some of which I am already raising in the greenhouse, and some to be sowed directly in the garden.

Now is a great time to sow Autumn and Winter veggies. The soil is still nice and warm, and the days are sunny and bright. Seeds will pop up quickly and have a great headstart before the cold weather really sets in. This weekend I directly sowed beetroot, radishes (Watermelon and French Breakfast), carrots (Purple Dragon), and peas (Telephone). I love to grow peas, but my success rate is so-so. I have two varieties to grow this year: a dwarf variety I bought in Tasmania (Keveldon Wonder) and Telephone, which is a climber. I think my success rate is low because I plant them too late. Hoping this year to fix that by planting much earlier.

Greenhouse Adventures

In the greenhouse, I’m still growing a range of Summer veggies, including capsicums (sweet peppers), cucumbers, chillies, beans, eggplant, and a solitary watermelon.

Capsicum have been the standout crop this season. I have never had much success with them, so it’s exciting to grow so many. However, aphids and whitefly are a problem. I had to pull out five chilli bushes as I was not able to get on top of the bugs. I think they enjoy the humidity and warmth of the greenhouse. I’ve been using eco oil and pyrethrum, but in the heat and bright light of the greenhouse, these tend to burn the plants. If any readers have another suggestion, I’d be glad to hear it.

My real joy though is the cucumbers – while I do not have many of them, the fact I have any at all is a matter of great pride. Every year I try to grow cucumbers, and at the end of the season, I vow: ‘never again!’ Then along comes the Spring, and somehow I find I have ordered cucumber seeds once again. The secret, for me at least, is to grow in a greenhouse (honestly, not such a secret – that is how they are grown for market).

I have planted seeds for the Autumn brassicas and leafy greens in the greenhouse planters, and they have popped up very quickly in the warm environment. My goal this year is to grow as many cauliflowers, broccoli, and cabbages as I can. I also planted kale, lettuce, onions, and bok choy.

Planting Native Seeds

The last seeds I planted were some natives I bought in Tasmania: Sawtooth Banksia, and King Billy Pine. This is my first foray into growing natives. When we were hiking in Tasmania, we saw both these plants growing in the wild: the Banksia beside Dove Lake in Cradle Mountain National Park, where it grew to an impressive size, and King Billy pine, both in the rainforest area of the Cradle Mountain National Park, and in a smaller version at the Royal Tasmanian Botanic Garden. In the national park, it was an enormous, awe inspiring, tree of magnificent proportions. Of course, I don’t expect to grow a tree of that size: my goal is to grow a version for a pot. How well it will grow in South Australian conditions, I don’t know.

The two plants require vastly different germination environments. King Billy must be chilled in order to successfully germinate. I planted it in seed-raising mix in a container, covered it in plastic wrap, and placed it in my fridge. I’ll leave it there for two weeks before removing it and placing it in a sheltered position to finish the germination process. The Banksia is much simpler: place in a container of seed-raising mix, and keep damp, away from full sun.

A Virtual Tour of the Royal Tasmanian Botanical Gardens

We have been fortunate to tale a trip around stunning Tasmania this past week, with the past few days based in Hobart. After a day spent at Salamanca Markets, and another at the Museum of Old and New Art, we walked to the Royal Tasmanian Botanical Gardens. Set on 14 hectares close to the centre of Hobart, the Gardens are one of the oldest botanical gardens in the Southern hemisphere (established in 1818). Our State was colonised in 1836, so the gardens are older than colonial settlement in our part of Australia. And it is obvious, just by the size of the trees. South Australia has some lovely trees, but they are teeny tiny compared to Tasmanian trees in the gardens, and even more so in the wild. I had heard the phrase ‘old growth forests,’ but I did not really understand the reality of it until coming to Tasmania. Trees here are giants. The RTBG has oak trees that could shelter the Merry Men. We have seen even larger trees since our visit to the botanical garden, but that was my first experience of really large trees.

My travelling companions took many photos (I’m not much of a photographer), which has allowed me to create this little virtual tour.

On arrival at the gardens, we were greeted at the gate by a friendly person who asked us our interests, handed us a map, and pointed us in the right direction. As our first goal was “COFFEE!”, she directed us to the cafe, and we stumbled forth. The cafe overlooks the water, so we sat for a while looking at the water and feeling very civilised before heading out on our garden walk.

Tasmanian Community Food Garden

Giant snowball pumpkin – you can’t tell from this photo, but it was about the size of a beach ball!

Once it was a working farm, then Pete Cundall established Pete’s Patch in this space, then it became the Tasmanian Community Food Garden, an organic community garden cared for by volunteers and community members. It produces four tonnes of fresh organic produce annually. On our visit, pumpkins, apples, tomatoes, pears, and herbs were growing in abundance.

I was happy to note that many of my own practices were also in evidence here. I did pick up some tips though: plant borage and calendula in among the pumpkins to encourage pollination. There were dozens of ripening pumpkins in the various pumpkin patches, so it clearly works.

Cinderella Pumpkins in the Community Food Garden

My husband took careful note of their technique for espaliering pears. We have multiple espaliered young fruit trees in our backyard but are always looking for more advice. The pear trees in this garden were beautiful, and covered with pears.

Much cooler is an apple tree arch. I wish I had space to recreate that in my garden.

I noted that the traditional ‘Summer’ crops that would be in full fruit in warmer States, such as chillies, zucchini, tomatoes, and eggplant, were not much in evidence here. There were a few healthy tomatoes and capsicum plants, but they already had brussels sprouts in the ground – we would not be planting these in SA for at least six weeks, and in my area probably not at all.

Japanese Garden

South Australia has a small but lovely Japanese Garden in the city. The RTBG Japanese Garden is about three times as large. It is beautiful, very tranquil, with many little hiding nooks for quiet contemplation. After a busy few days, I enjoyed finding a quiet spot to sit for 15 minutes.

Tasmanian Native Garden

The Native Garden was quite large and clearly well-designed and considered. This was my favourite section of the RTBG, because it was so well-thought out, and I did not recognise many of the plants. Each plant was accompanied by a description of its traditional and medicinal uses.

Conservatory

If you’re a reader of this blog, you’ll know I have a fascination with greenhouses. The RTBG has a gorgeous stone and glass conservatory, that houses a fountain and hothouse plants that would struggle to grow outside in Hobart’s cool temperate climate.

The stone fountain was so relaxing it inspired me to consider adding a water feature to my garden. This is something I have avoided for many years, due to the maintenance. However, I think a solar powered water feature in the patio or greenhouse might be worth considering.

Of course, my greenhouse has been set aside for productive plants, while this Conservatory is decorative. I still found it inspirational. You can see a variegated ficus in the foreground of this photograph – beautiful! I’m going to search for one when I get home.

Heritage Cottage

The Heritage Cottage was the first building constructed in the gardens, and was originally a dwelling. Now it is a little museum showcasing some early botanical drawings and horticultural equipment, like an early terrarium design (see below).

My youngest and I both love botanical drawings and paintings, so we loved looking at the early colonial botanical drawings.

The Tasmanian Royal Botanical Gardens were my favourite place to visit in Hobart so far (we are going back to Hobart for a few more days). We spent most of the day there. If I lived in Tassie, I would visit regularly. If you are ever in Hobart, I recommend a trip – it is a beautiful, relaxing, and inspirational garden.

Catching up in the garden, January 2023

It’s easy to fall behind in the garden when you only have a few hours a week. I have been keeping up on basic tasks, like watering, but a big garden like ours has myriad tasks that need to be managed regularly – and I have not been keeping on top of them. These include weeding, feeding, pest management, pruning, picking and processing the harvest, and removing spent plants. My husband and I made an agreement to get up early and get out in the garden. We both broke that agreement by lazing around in bed for longer, but we got out there by about 9:30 am, ready, if not exactly raring, to go.

Summer Pruning

Most pruning is completed in Winter, when plants are dormant. However, trees in the prunus family, such as apricots and plums, benefit from a prune in Summer after they have finished fruiting. This is because they are prone to diseases like gummosis, which can get into the cuts in the wood if the weather is damp. The apricot tree finished fruiting two weeks ago, so my husband got up on his ladder and started to prune it back. We are putting the branches on the workshop roof to season for next year’s fireplace. Firewood is expensive, so any bits and pieces we can pull together ourselves from (non-toxic) prunings saves cash.

While he pruned the apricot and plum trees, I pruned the grapevine, just a little. The wet weather in late Spring caused the early leaves and bunches to rot. New healthy leaves have since grown, but I have been intending to prune off the rotten leaves and bunches for weeks now. The vine looks much happier, if a little bereft, now. Real grape vine pruning season is in Winter, so I only pruned off the funky looking leaves.

Tomato Supports

I admit to putting off tying up tomatoes, because it’s an itchy and boring job. But there comes a point in the season where it is just necessary. Rather than using stakes, I prefer to build cages. I have tried all kinds of versions of tomato cages, but my favourite (also the quickest but one of the most expensive, unfortunately) is to use steel trellis panels, which cost about $15 each when I bought them from Bunno’s two years ago. I create a cage using four panels, tied together with zip ties. These are easy to build and easy to dismantle. Due to the cost and size, I use this style of cage for the largest indeterminate tomatoes (generally Green Zebra).

The king of tomato cages is my brother, who builds very impressive structures, possibly visible from space, and also has the most impressive tomato plants in the family.

When I run out of trellis panels (and I refuse to buy more because a) cost and b) storage – I have to store them for the nine months of the year I am not using them), I build other types of supports for the other tomato plants in the garden. I have a group of three plants against the fence behind the lime tree. Using a large piece of reo mesh and two star droppers, I built a trellis to support this group. I have another piece of reo I am hoarding to build a trellis for pumpkins once they grow too large. I caught one pumpkin vine climbing the lime tree this morning, so it will not be long before I have to build a structure for it.

Of course, I could spend all day building cages for the rest of the plants…but I was feeling a bit lazy, and it’s a bit fiddly. Therefore, I decided that the standard stake and stocking tie support system would be fine. I only use the stake supports for smaller tomato plants, as they can quickly outgrow stakes if they are very vigorous plants.

All of these supports are recycled from previous years. I save the reo and trellis panels each year, and reuse the ties from previous stakes. If the stakes are not damaged from the last season, I reuse them as well. Some gardeners prefer not to reuse wooden stakes, due to problems with passing on soil borne diseases. However, I let the stakes dry out in the sun for a few days. After storing in the garden shed for twelve months, I figure they are probably ok. Once the stakes are too old and broken to reuse, I chop off the grotty end and they are used for firewood.

This season I grew all the tomato plants in my garden from seed (puffs up chest). A couple of the plants I grew from supermarket tomatoes that I thought were delicious, and saved some seed. I found one of these in the garden this morning (I had completely forgotten I had planted it). It has fruited like crazy (all green right now). I really hope that it is as delicious as I remembered. If not, I will use it to make some sauce. At the moment I am only picking a couple of cherry tomatoes a day (yellow Windowbox tomatoes – they are ok, but not really tasty). Can’t wait until the Green Zebra and Black Russians ripen up.

Feeding

The day was relatively cool, so I gave every plant in the veggie garden an organic liquid feed of the old faithful standbys Charlie Carp (a liquid fertiliser made of carp, a pest) and liquid seaweed. The grapevine and avocado tree was fed a bucket of liquid fertiliser as well. My plan for the avocado tree is to keep the water and food up each month, as tbh I have been a bit slack on both over the past twelve months. For the lemon tree and passionfruit, I also dissolved iron chelates in a watering can and watered ten litres into the root zone of each plant.

Iron chelates are a trace element that do not need to be used regularly. However, the leaves on these plants were looking yellowed, and the fruit was shrivelling. Poor fruit and yellowing leaves can be a sign of iron deficiency in fruiting plants. Iron chelates are easy to apply, following packet directions, but it is important not to overdose.

As the other plants (tomatoes, eggplant, capsicum) are all looking healthy and are setting healthy fruit, I do not think it is a problem with the soil nutrition generally. However some fruiting plants are much hungrier feeders than others, so it seemed a good idea to give them a dose of iron chelates to see if this will help. Time will tell. Really, looking at those passionfruit leaves, it honestly couldn’t hurt – they look so bad. This is the problem with having such limited time – there is so much to do and so little time to get everything done. I was aware there was a problem, but I may have been too slow to fix it.

The Greenhouse

The greenhouse continues to be a successful growing space. I have been unscientifically comparing the progress of plants in the greenhouse to those planted outside.

These two eggplants were both grown by seed by me, and were planted at about the same time. Eggplant One was planted in a raised bed outside, in a premium potting mix. It is watered daily, and has been fed with a liquid feed at least fortnightly.

Eggplant Two was planted in a large pot, in the same brand of premium potting mix. In hot weather it is watered twice daily, and has been fed with a liquid feed at least fortnightly.

As you can see, it is at least three times the size of Eggplant One, and is flowering. With all other factors being equal (type of soil, feeding regime), greenhouse conditions seem to encourage faster growth.

Previously I have used a heated seed mat to raise seeds in small trays indoors. While the heated seed mat germinated seeds more quickly than without, the plants did not have as much light as they needed, and struggled past the initial germination phase.

I planted these borlotti bush beans nine days ago in the raised troughs in the greenhouse, watering daily. They have almost all germinated, and already have their true leaves. As they are bush beans, I will keep them in the trough for their lifecycle. I have climbing beans in the garden as well, which were planted six weeks ago, and are only about twice the size of these beans.

I believe that the relatively constant temperatures and excellent light in the greenhouse creates optimum growing conditions.

The greenhouse is not without pest problems. One eggplant was initially affected by whitefly, and another by white cabbage moth caterpillars. These were easily controlled by manual means (squishing). Occasionally small sparrows manage to get in, and cannot seem to figure how to get out without a little assistance. But generally, the greenhouse protects plants from most pests.

It does require consistent and diligent watering. Unlike the outdoor garden, which I can leave a day if I’m busy, it is not possible to skip watering the greenhouse. This is due both to the fact that the plants are all in containers, which dry out more quickly, and the higher temperature. Leave them for a day, and I could end up with dead plants.

My other main concern is pollination. While insects can come into the greenhouse, I worry that not enough pollinators will come in. I am thinking through different ideas to attract them – if any greenhouse gardeners have some suggestions, I would love to hear them!

Of course, I still have many tasks left to complete, but there is never enough time. I still have to work, see family, exercise, be a friend and partner and parent…life is not all gardening! Hopefully what I have done this weekend will hold the garden together for a little while.

Gardening jobs, Christmas and New Year 2022

Happy New Year!

It’s finally really lovely and warm in our parts. I have had lots of jobs to do to keep the garden alive and well, including watering the containers and raised bed daily, and keeping the watering up across the whole garden. I don’t mind this, but it is a job of work.

Fortunately, I’m on a break for the Christmas/New Year period. This is my first proper break in over a year. I am taking full advantage, getting out to the garden every day.

Garden progress

The long, cool, and wet Spring stalled the progress of eggplant, zucchini, chillies, and tomatoes, which would normally be in full fruit by now. One of the cherry tomatoes I grew from seed, a variety bred for pots called Window Box, is the only one that has fruit so far. It is a dwarf breed, unusual for a cherry tomato, and has a lot of flowers and clusters of fruit already. Apparently the fruit is yellow. I’m looking forward to tasting the fruit. I have found that some of the new breeds of cherry tomatoes do not taste great (last year’s Blueberry cherry tomato was, in my opinion, yuck). I hope Window Box is tasty, because I have about six plants. All the other tomato plants have put on good growth and have started to flower, but no fruit yet.

As for my dreams of expansive eggplant crops, it’s not looking great. I’m thankful for the greenhouse, which will allow me to grow eggplant well into Autumn. I have planted another punnet of eggplants, as well as more seeds, with plans for a long season of eggplants in the greenhouse. Fingers crossed!

Greenhouse

Speaking of the greenhouse, it’s coming along nicely. For the first time EVER, I have planted eight watermelon seeds, and have germinated eight watermelon plants. These were a gift in a seed swap from a friend (an heirloom variety called Moon and Stars). Watermelons, along with cucumbers, are my Achilles heel, so if I can even grow one watermelon from this lot I will be very proud of myself.

The watermelons were exciting to watch. In the morning I found one had popped up from the warm soil. About an hour later, my niece found another poking its head up. By the afternoon, all eight had germinated and were stretching their leaves to the sky! How fun gardening is!

I also have cucumbers popping up, more eggplants, and basil. This greenhouse is so much fun.

Chillies Galore

At last year’s Chilli Festival I bought some chilli plants (a Devil’s Tongue, and a Four-in-one pot of a Mango chilli, a Lemon chilli, an Ajo, and a Curly Toenail). While I was not a fan of the Mango chilli, all the rest were great (the Devil’s Tongue is an old family favourite – very hot with a delicious flavour, and prolific). Following the advice of the stall holder, at the end of the season I cut them back by 50% and let them over winter. A couple of the four-in-one did not make it, but two did (I won’t know which until they set fruit). Over Spring the others put their leaves back on and have now started flowering happily. I’m looking forward to full crops of the others.

I also raised quite a few other chilli plants from seed, including Serrano, Gunter, Jalapeño, and Chocolate chilli. These are still quite small, but I’m hoping for a good crop. We eat chilli most days, and appreciate the flavour profiles of the different chillies, so growing many varieties is worth the time and effort for us.

The orchard

The apricot and mulberry trees are ready to harvest, and we are watching them like hawks – and so are the parrots! We have the biggest apricot crop we have ever had. The tree is too large to net, and I don’t like to do that anyway – I don’t mind the birds having some of them. But if we want to save any for ourselves, we have to pick as soon as they blush – so we check daily. We go out early in the morning and pick as many as are tinged orange, then wait for 24 hours to check again. We leave them to ripen on the kitchen bench.

Mulberries are kind of a pain to harvest. They ripen a few at a time, I think because our tree is still relatively young. We pick a couple a day, then wait for the next lot to ripen. The tree itself is beautiful, so I would not consider removing it (yet), but it has not lived up to my mulberry jam dreams.

We have a big crop of passionfruit and pomegranates coming on, but they are way off yet – at least a couple of months.

Cleaning up and potting up

A big and boring part of the past couple of weeks has just been cleaning up. I dug out the raspberry canes that have not done a damn thing over the past two years, and pulled out more bits of Audrey II, the boysenberry plant, that continues to make her presence felt (even though I dug the main part out months ago). I suggest to you that if you want to grow berries, set aside a bed that is completely separate from any other part of your garden, let them go, and don’t grow anything thorny!

At this time of the year, many of the Spring flowering annuals and herbs have flowered and are starting to set seed. They are generally looking tired and ratty. I have been clearing out all of the dead sweet peas, nasturtiums, parsley plants, and anything else looking old, dead, or tired. It’s taking quite some time and filling up my green bin quickly. To fill in the gaps I have sprinkled fast growing annual seeds like Cosmos, or planted quick growing annual colour, like Petunias. In about six weeks, I’ll start planting Spring flowering bulbs.

I’ve also repotted some sad looking houseplants, including an Umbrella plant that was miserable. I’ve had it for two years, and it started dropping leaves. When I repotted it, I found it had sported two babies. So for my repotting efforts, I have three plants now instead of one. I also repotted my beautiful Spotted Begonia, moving her up to a larger pot. She is much happier now, and I removed one of her leaves to strike into a new plant. Begonias strike easily in water, and are very easy to grow in the right conditions. I have two now (one struck from the mother plant), and they flower profusely with very little attention from me.

Greenhouse Setup

The greenhouse was built several weeks ago now, but I have not really had any time to use it yet.

Firstly, I am working flat out up to Christmas. I have been stealing a little bit of time in the garden on weekends, but I am working most weekends as well.

The other reason is that while the builder had built the lovely greenhouse, we had left a bunch of junk in there. He kindly built around it, and although he offered to move it, we knew it was our responsibility to shift it all. This junk included a big stack of pavers and sundry other crapola. Shifting the pavers took me the best part of a full day, because I also had to clean them all. I discovered quite a few species of technicolour spiders I had never seen before, some teeny gecko skeletons, and a big old nest of ants.

We posted the whole lot on Gumtree (the pavers, not the critters) and gave them away the next day.

Once the space was clear, I had to order shelving, racks, and planters. I went to a few places locally to see what was available, and also looked on Gumtree for secondhand racks, but there was nothing suitable. I ended up going to the ~~evil empire~~ Amazon for raised planters, a stainless steel kitchen bench, and stainless steel plant racks.

All these have started to arrive, and thanks to the assembly skills of my husband and various teens about the house, they are now set up in the greenhouse.

I have planted up three of the planters with seeds (watermelons and cucumbers, as well as having another crack at eggplants, for the final time this season). One planter has been set aside for my youngest kiddo and my nephew to play around with, as they have both expressed an interest in learning to garden.

When the bench arrives, it will be placed in the centre of the greenhouse so I make good use of space. That will be the potting area.

This time of year is not ideal for a greenhouse (Summer in Southern Australia), except…it has been unseasonably cool. So I’m going to keep playing around with the greenhouse and will try my luck growing some melons and cucumbers in here this season. Where it will really come into its own will be the cooler months. I’m pretty happy with the whole setup – it’s neat, it’s functional, and mostly, it’s just hella fun.
