Sixty Things To Sow Or Plant In The Coastal Subtropics In Mid-Winter? I’d Like To See That…

What can I sow or plant in the coastal subtropics in winter? Now the mid-winter solstice is behind us, days are cool but lengthening – ideal for sowing watercress, dwarf beans and snow peas. This winter, like the last five, has been mild, slightly damp with just two cold snaps so far.

It’s time to lift, multiply and replant yam, elephant foot yam and cocoyam, my favourite staples. Let’s hope drizzle and humidity stay away, otherwise we’ll have tomatoes infected by canker disease and anthracnose disease infecting mango and avocado flowers. The best news is there’s a long list of delicious food plants that can be sown now for your spring menu. Here’s sixty to get you started. Just think of all those recipes you can use them in!

White Westerners would do well to grow and use chillies that are really hot, not just what they perceive to be hot, if they genuinely seek to deter possums 🙂

Always follow crop rotation each season.
If you don’t do it, even a raised bed or window box can accumulate unwanted diseases and pests. Crop rotation is vital as it frustrates pests and diseases, making life hard for them to flourish on their favourite hosts. Crop rotation has the reverse effect on food plants, it helps them thrive.

In each rotation, grow new crops that are botanically unrelated to the ones you have just removed. So, by replacing capsicum (Solanaceae family) with kale (Brassicaceae family) you limit opportunities for pests, like root knot nematodes, to do their worst. This is the fundamental way that crop rotation operates, so understanding a little backyard botany can simplify food production and improve your harvest.

Control perennial weeds before sowing or planting. I pour boiling water on bulbous Oxalis before disturbing the soil.

Prepare a proper seed bed before sowing;

Use fresh propagating mix for sowing and cuttings. Can’t afford to? Then pasteurise old mix by adding boiling water, allow to cool, then sow;

Practising successional sowing is one way to extend your picking season of favourite varieties;

Save seed from your best plants and eat the rest. Last week, I saved coffee seed. This week, I’m saving seed from my eggplant ‘Listada de Gandia’ and my chillies. Here’s my tip on how to make saving eggplant easy, quick and simple. The only secret here is using a similar domestic blender. Why? A commercial grower attempted the same on a massive scale by using an industrial liquidiser. The result wasn’t the same – instead of separating the flesh from the seed, they pureed both eggplant and seed.

Protect tender crops overnight when cold snaps are predicted.

Watch out!

Protect tender crops, like tomato and eggplant, from cold snaps by draping old net curtains or shadecloth over them overnight, removing them at sunrise.

Control scale insects and rust mites on citrus, hibiscus spinach, and general fruit trees by spraying with lime sulphur;

Control virus-spreading aphids, especially on onion crops and banana suckers by spraying with horticultural soap;

Deter possums from ravaging leafy crops by spraying with my atomic chilli spray formula. If you don’t grow Carolina Reaper or Bhut Jolokia chillies, maybe now is the time to order seed;
