(Best months for growing Cabbage in Australia - tropical regions)

  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings
  • Easy to grow. Grow in seed trays, and plant out in 4 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 5°C and 18°C. (Show °F/in)
  • Space plants: 50 - 75 cm apart
  • Harvest in 11-15 weeks.
  • Compatible with (can grow beside): Dwarf (bush) beans, beets, celery, cucumber, onions, marigold, nasturtium, rhubarb, aromatic herbs (sage, dill, chamomile, thyme)
  • Avoid growing close to: Climbing (pole) beans, tomato, peppers (chili, capsicum), eggplant (aubergine), strawberry, mustard, parsnip

When is it best to plant cabbages and kale in zones 6b and 7a? And bok choy in these same zones?
28 Jun 23, (USA - Zone 6b climate)
In zone 6 sow Bok Choy seeds in April, Kale seeds in July and August, and Cabbage seeds in April, July, or August. For zone 7a, Cabbage seeds are best sown in January, February, March, August, or September, while Kale seeds thrive when sown in February, March, or August. Bok choy seeds should be sown in August or September for optimal growth.

Planting cabbage this weekend hopefully does not get too warm too quick.

What varieties of cabbage should I plant now?
03 Oct 22, (USA - Zone 4b climate)
Any. What you want to eat.

Live in zone 8A Midlands SC but right next to coastal , It's Feb 10, I'm confused about when to plant Cabbage, If Cabbage does well over winter why not now before it gets too hot? . I'm going to try. I put just 12 seeds in pots for transplants, AND going to try seeds in ground today or tomorrow. Any midlands of SC out there?

Also Midland's area (30 minutes north east of Columbia). Here it is late June and I just considered cabbage my garden. I guess I'm going to start some seeds inside late next month then more in late August before moving to the garden in late September. I'll call it an experiment. BTW, how did yours do?

I live in the Midlands of South Carolina. I think it's agricultural zone 8. Looking for cabbage I can plant right now

Too late to plant now - check the planting guide here.

Well, not entirely true. I got some cabbage seedlings from a nursery that was tossing them. We put them in to the ground on December 3. Then we have them covered with a small hoop house. We also have some incandescent lights to add just enough heat when the temps dip down into the twenties.(F.) You can grow them and they are a challenge, but brassicas like cabbage, kale and broccoli are pretty frost hardy if you give them cover.

Are you direct sowing (into the garden), or are you sowing indoors in trays? I'll give you the germination temperatures. Germination temperatures vary from plant to plant (even among say tomatoes - the various varieties have different germination temperatures). These are OPTIMAL germination temperatures-- so higher or lower can work, but germination will not be as consistent or Good in non-optimal temps. The germination temperature must be sustained (over several days or more) -- this is the plant's indicator (sustained warm temperature), that spring/summer is here -- and it is time to wake up and get growing. If the germination temperatures are not met, the seeds will remain dormant (most of them), waiting for their ideal growing conditions to occur. Remember - varieties make a difference so I'm giving you GENERAL temperatures. PEPPERS: Soil temperature needs to be at least 75-85 degrees F (24-27 c) for good germination. Peppers won’t germinate in cold soil– with the higher end temps germination may be in 5 days, or may take up to 20 days in the lower temps. Don’t overwater seeds or they may rot. peppers don't like to be overly wet. Your max germination temp is 95F (35c) for peppers. TOMATO : optimum germination temps are : 65-85F (24-30c) days to germinate varies a lot by variety ... so maybe 1- 2 weeks ? Max temp is 95f (35c). Tomato seeds have been know to germinate at temp as low as 40f (4c) -- but expect germination to take a month or more and your germination rate (% of seeds that germinate) will probably be very low. GREENS: way to varied to give an answer -- example: KALE has an optimum germination temp of 65F (18c) and range of 45°F - 85°F (7-30c), while SWISS CHARD's optimum germination is 80°F (27c) with a range of 40°F - 95°F (4-32c). Days to germination vary based on variety and temp. I generally recommend starting peppers and tomatoes indoors -- and with greens it depends on the green -- kale and chard are both tough, and both have a very wide temp range for germination so outdoors is fine. You also have to consider insects... larger plants have a better chance (in general) of survival if you experience pest problems. OF course a lot depends on how long your growing season is-- in a really long and hot growing season, starting tomato seeds outdoors is no problem, in a shorter cooler growing season the optimum germination temps may never be met (sustained) so starting indoors is pretty much a given.
