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.
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.
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.
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 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.
