Subtropical Zone - warm humid summers

What to do in the garden


Its March and temperatures are starting to cool. This is a busy month as beds need to be prepared in readiness for planting autumn and winter crops. These are those traditional north European vegetables, with a few Mediterranean types thrown in as well. Organised gardeners would have begun clearing some areas towards the end of February, and these areas can be progressively dug over, incorporating composted organic matter and a balanced organic or biological fertilisers containing ground rock minerals and humates.

Some of the European vegetables need a long, cool growing season and each year the subtropical winter growing period is getting shorter and shorter. I lay out my winter garden based around slower growing plants, trying to time sowing for the week when night temperatures suddenly fall – generally late March, but last year, in mid-April.

These long season (slow growing) plants include: broad beans, cauliflower, drumhead cabbage, globe artichoke (fast flowering types grown as annuals), wombok and Chinese cabbage.  I like to give these plants plenty of room (500 to 900mm) and sow faster growing plants between them while young. These quick crops include rocket, corn salad/mache, purslane, bok choy and choy sum.

Lettuce thrives over the autumn and winter months, and seems to suffer from fewer pests or diseases.  I sow a few different varieties each month along with some of my favourite salad greens – corn salad/mache, wild and salad rockets, purslane spinach and lime streaks mustard greens.

Tomatoes continue to grow well throughout winter, suffering minimal pests or diseases, especially if you rotate plants around the garden each season. Cherry and currant types are great for beginners. I also like to grow Russian varieties at this time of year. They grow well in a sunny spot and the flavour is amazing.

What to do in June

Plant strawberry runners

Bare root strawberries can be planted now. Build up the soil to form a small ridge; this ensures that the plants will not get wet feet. Keep a look out for pesky snails and set traps if they become a problem.

Cut back green manure crops

Early sown crops of green manures can be cut back before they begin to flower. Slash down the foliage with a brush-cutter and dig it into the soil to break down.

Prune back raspberry canes

Plan to prune raspberry canes soon. Autumn fruiting varieties are simply cut back to the ground, whilst summer fruiting varieties need to be tip pruned to develop fruiting canes next season.

Vegetable Growing Tips

Starting a vegetable garden

- Choose an area that gets full sun and is not too far away from your house. The mid-winter dash to the vegie patch will be easier! 

- A good, healthy soil is the foundation to success so focus on improving the soil before you do any plantings. 

- Know what to sow, when to sow and how. Every vegetable seed has its own growing requirements. We offer a beautiful heirloom Seed Sowing Guide here and a 2018 Gardeners Diary with space for seed packets, garden plans and notes here.
