Just remember that "Perth sun" is stronger than normal sun. so most plants that are "full sun" need partial shade in our summers. Now is definitely tomato and basil season. I would figure out what you like to eat first and put those in as a priority and work around them. Ask your local garden centre including your local hardware garden centre :)

I would dispute that the Perth sun is stronger than normal sun. 35 or 40 degrees is the same everywhere. It is the humidity or dryness that is the difference. A humid 35 degrees in SE Qld is just as prickly as a 40+ dry Easterly in Perth. I have lived in both and I know which I would prefer - WA.

Look up the internet for how much sunlight vegies need. You can find a table that shows this. Some need 4 some 6 some 8 hours. Most plants need quite a lot of sunlight - otherwise you end up with small weak plants.

My Basil is being invaded by caterpillars. How can I get rid of them?

Small green caterpillars. Either pick them off by hand or sprinkle with ground pepper for an organic fix. You may need to squirt leaves with water first. This works with spinach and mint too.

I was given a basil plant yesterday - from up north Queensland. He said it flowered in the late winter - spring. Growing it for bee attraction. Will ask what it is called tomorrow.

This plant is now a 1.2m ball of leaves and flower/seeds.

Basil is frost-tender and needs lots of sunlight

I garden at a men's shed and the boss bought some perennial basil back from Townsville to Bundy in June. I planted it in a light truck tyre with some good soil, put a supporting wire mess cone around it and boy has it grown. It is now a 1.2m ball and has heaps of flowers and bees.
