September across Australia
September is the start of spring and one of the busiest months in the garden. The soil is warming, frosts are becoming less frequent (though still possible in cooler regions), and it is time to transplant the seedlings you started in August. Spring planting is all about timing: get warm-season crops in as soon as frost risk passes, but not before.

September Gardening Tips
Transplant tomato, capsicum, and eggplant seedlings after the last expected frost date for your region. Harden them off first by placing trays outside for a few hours each day for a week before planting out.
Direct sow beans, corn, cucumber, zucchini, and pumpkin seeds into warm soil. Wait until soil temperature reaches 18 degrees at 10cm depth. If soil is still cold, delay by 2 weeks.
Plant herb seedlings: basil, parsley, coriander, dill, and chives. Basil needs warm soil and no frost risk. Coriander and dill prefer the cooler end of spring before summer heat causes bolting.
