(Best months for growing Eggplant in New Zealand - cool/mountain regions)

S = Plant undercover in seed trays T = Plant out (transplant) seedlings

September: Bring on in pots - need a long growing season

  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 24°C and 32°C. (Show °F/in)
  • Space plants: 60 - 75 cm apart
  • Harvest in 12-15 weeks. Cut fruit with scissors or sharp knife.
  • Compatible with (can grow beside): Beans, capsicum, lettuce, amaranth, thyme
  • Avoid growing close to: Potatoes
  • A seedling
  • Eggplant

A large bushy plant with attractive purple flowers. Different varieties have different colours and sizes of fruit, ranging from the 'classic' large purple to the Thai small white varieties and Brazilian red.

Has spiky stems. Wear gloves to harvest fruit as the spikes on the calyx are sharp enough to break one's skin.

In cold climates grow in heated greenhouse and reduce artificial heat during summer.

Perennial in tropical climates otherwise grown as an annual.

Needs a long season. Start under cover and plant out when frosts have finished.

Some varieties with slim, long fruit such as Asian Bride produce their fruit earlier. Mulch well and keep well watered. May need staking

Culinary hints - cooking and eating Eggplant

Cut and use the same day if possible.
Slice, no need to peel, and fry in olive oil.
Brush with oil and grill or bake.
Or microwave,plain, for about 4 minutes on high.
Makes a good substitute for pasta in lasagne or moussaka.
Can be smoked over a gas ring or barbecue, cooled and peeled and used to make dips.

Use the Vegetables and Herbs tab - top of the page - click on chosen vegetable, then check that the right zone is selected - top of the page - for most of Sydney it is Sub-tropical.

I have two egg plants that have given fruit and still have few flowers. What should I do for the next harvest? Pull them out and start again? Cut it back? Just leave it? Many thanks.

From the notes here about egg plant.

You should be able to get a good second season crop from eggplant. Best to cut it back and pull off any flowers although a little late in the season. I've got two I cut right back at the start of winter and they are still growing well, as the temperature gets up they will take off. I've also got another going into a third season that looks healthy after a fantastic second season crop but this will be new territory so don't know what to expect third time around.

Some varieties do have greenish fruit.

Yes there are some green eggplant. I have found the last few years when the plant has cropped for awhile and the soil is maybe running out of nutrients etc the fruit becomes a bit deformed and is green and purple and doesn't look very attractive. I don't know why this happens - could be weather, trace element deficient - could be one of a hundred different reasons. If I have had a good crop then I'm happy and it's time to pull them out. My eggplant self germinates from fruit left on the ground from last year and dug in. Probably won't germinate until Oct/Nov.

Look at the top of this page and read it and take notice of what it says. You are temperate zone - plant seeds Aug to Sept - transplant from Oct to Jan. It needs soil temp of 24-32 to germinate. My soil temp(Bundaberg) is presently 18 degree - so I shouldn't be even trying to germinate eggplant for another 6 weeks - I'm sub tropical. IT IS a summer crop - NOT a winter crop. When they grown the right time of the year, the fruit will be purple right from when they start forming.

Hi,I’m from Melbourne in the northern suburbs. I have about 5 eggplant plate 2 different varieties. We had a great season. Some plants are still having fruits. It’s middle of July, temps drop to about 2c in early mornings. Is it better to uproot plants and start new this season or trim back and let them re grow this season..? Trying to plan my veggie garden to start planting in September. Any advise is appreciated. Thanks.

lack of pollination. Egg plants self, but at some times (weather ?) need some help. Take an cotton bud, gather pollen (yellow) and apply to stigma (single central erect part). Watch any utube on search 'pollinate egg plants'.
