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.

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.

Seasonal gardening jobs, 21st August 2022

Chickens are an important feature of an organic garden — Chickens love to dust-bathe in the sunshine

It’s that time of year to start thinking about seasonal gardening jobs – in our part of the world, jobs for the Spring garden. This weekend that means starting seeds, caring for hens, and making plans for a fruit tree before I run out of time.

Caring for chickens

Sunday morning dawned foggy and chilly, but soon cleared to a sunny but cold day. It was also chicken coop cleaning day, so I let the little marauders out of the pen while I mucked them out.

Chickens are pretty easy pets to keep. We have four ISA Browns, which were the only type of hens we could get during the pandemic chicken frenzy of 2020. My goal has always been to have Australorps, an Australian heritage breed, but I could not find them at the time we were looking for hens.

ISA Browns are a hybrid hen bred for egg laying. Our four cluckers do lay really well. They are in their third year and are still going strong. They are also curious, cranky, naughty little dinosaurs that love to rampage through my veggie patch if I let them.

The four main things you need to care for chickens are:

A fox-proof coop and run: We purchased our neighbour’s shed (he built a new Cluckingham Palace, and sold us his old coop for $100). He helped us to re-build it on our side of the fence, and we got a solid coop for less than we would spend on materials to build a new one. They have a large space to run around and dust-bathe outside, as well as occasionally free-ranging in the backyard. Don’t think you can get away with not securing the coop. Foxes are a legitimate pest in most urban and peri-urban regions of Australia, and they will take out a flock of chickens very quickly;
Bedding straw, and time to clean them out regularly: I clean the run and coop out every two weeks, raking out and replacing their bedding with fresh straw. I buy a bale of bedding straw for $9, which lasts me (well, them really) two months;
Good quality poultry food: Our hens prefer Red Hen Free-range Layer Mix. We buy a 20 kg bag for $33, which lasts four hens a couple of months. Their food is supplemented by kitchen scraps and green feed from the garden;
Time: Healthy birds take a bit of time. I need to spend about two hours every two weeks cleaning them out. We also obviously have to feed them daily, water them, put them to bed at night, make sure they are kept safe from foxes, and generally keep an eye on them.

I check on the birds’ physical health every time I clean the pen by picking them up to see if they have healthy feet and feathers. I also check in their pen when I am cleaning it for any signs of mites or lice. So far, we have not had any problems. That could just be dumb luck, but I do think chicken hygiene plays a part. Regular cleaning of the coop, fresh water, and giving them only as much food as they can eat in one day prevents other pests visiting their coop.

Why have chooks?

I have chickens because I like them. I’m not a furry animal type of person (we don’t have dogs, cats, rabbits or any other fluffy creature), so chickens fulfil my need to have non-human creatures about the place. They are my favourite animal – I find them soothing company. However, there are some other good reasons. Because we have the space, chickens contribute to our little organic gardening ecosystem: they reduce waste by eating a lot of our kitchen and garden waste, their manure becomes compost, which in turn feeds the garden. They give us eggs in return for their food and space. We eat some eggs, but not as many as they give us, so we usually give some away.

However, if I did not have the space or if I was renting, I would not have them. They do require effort and time, and some expense. In the twenty years we rented, we only had chickens one time, because we had a very chilled landlord.

Seasonal gardening jobs – late August

After cleaning the hens and turning the compost, a job I do at the same time (with some help from the chickens), I did some weeding and reviewed the garden.

Chickens can be part of an organic gardening system — The chickens love to help me turn over the compost

It’s been an extremely wet and cold few months in our area. The brassicas have not grown quickly, and I was starting to feel concerned I will not get anything before Spring hits and they go to seed. But walking around the patch this morning, I could see that many plants are starting to shake off the Winter doldrums and are putting on some growth. I plan to pick a bunch of collard greens this week – I am very excited about this.

We picked the last of an Autumn batch of Cos lettuces last week. These were in a raised garden bed, so I refreshed the soil with a bag of potting mix and watered it in well. Then I planted new lettuce and spinach seeds, hoping for a quick Spring crop of both before it gets too warm. Spinach has been my nemesis this year, so I’m not holding my breath. Lettuce has been an absolute winner though. This time I planted more Cos Paris Island, a lovely red Cos lettuce, and my favourite, Marvel of Four Seasons, a red butter lettuce. I’m sure I mostly plant it because I love the name, although the lettuce is tasty too. If you are in southern Australia, you will have time for a quick crop of lettuce, chard, spinach, or Asian veggies like Pak Choy or Tatsoi before the hot weather causes them to bolt to seed. Just plant ASAP now that the sun is coming out and the days are longer.

Seed Starting

I started the first of the Summer veggie seeds last week on the heat mat. I’m going in hard on eggplants and chillies this year, as I mentioned last week. But I’ve also started more Spring Onions (Red Candy Stick), bulbing onions (Barletta), some more Chard (Rainbow), Capsicum Golden Marconi, and Green Zebra tomatoes. Next on the list are all the eggplants – this season I’m growing four kinds. I completely caved when I saw the seed catalogues, and bought a heap of different varieties to try. I bought my seeds from Happy Valley seeds and so far I have been really happy with the price and quality.

I’m not banking on seed-raising like I did last season. This time, I’m treating it as a fun hobby. If I get to the first week of October and I don’t have enough homegrown seedlings to plant out, I will go to a nursery and fill in the gaps. I don’t want to lose any precious warm growing months.

Bare-rooted fruit tree

It’s almost time out for planting a bare rooted fruit tree (apples, quinces, nectarines, etc). In some parts of our State, I wouldn’t bother – it’s too late. But in my area, we are usually about six weeks behind the weather patterns of the rest of the State. Therefore, I’m going to take a punt and buy a bare-rooted fruit tree next weekend. I have a spot where Audrey II, the ill-fated boysenberry cane used to be. Her trellis remains, and I want to plant a tree that I can espalier. My plan is for a Quince, but I will settle for another Apple. If I don’t get it in the ground next Sunday though, I know I will have left my run too late and will have to wait another ten months.
