  • 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 75°F and 90°F. (Show °C/cm)
  • Space plants: 24 - 30 inches apart
  • Harvest in 12-15 weeks. Cut fruit with scissors or sharp knife.

Egg plants are very hungry for Nitrogen. Mine are fed abundantly, mostly with horse manure and compost and some chook manure. I have at least 10 good size fruit per plant. However they do not seem to fully ripen, always a little greenish just under skin when cut. They still taste fine but I am told they are much richer in taste if fully ripe. any clues??

I too have a problem with the Aubergine not going dark, actually is yellow sometimes the growth is stunted. My soil type is almost neutral.

Thanks David. I suspected too much water could be a culprit and I'm going to do the potash thing. Happy eggplanting!

Marina: I was having the same problem (West Sydney). I finally solved it by watering every other day and 1 application of a handful of potash. 2 plants have so far given 5 with 5 more fruit growing and 4 more flowers

It's late March. My purple egg plants have lots of blossoms but most fall. Very few carry to fruit? Any ideas on why this is so?

Same comment as Greg, I'm in Adelaide and the longer I leave the fruit on the tree the paler they seem to become. Is it still okay to eat?

I think I made the mistake of only planting a single Eggplant seedling. It seems to be growing very very slowly (if at all). Are there any tips on having them flower and fruit. It is currently planted in ground, facing north and getting full sun.

Planted five into the ground and two in pots. All are fine and have yielded on an average two fruits. Quite some pests - mites etc. Regular spray of fine water to dislodge them. The only fertiliser used was blood n. bone with some calcium nitrate.

I am growing eggplant in Wellington in a plastic house. Plants seem healthy enough and keep putting out flowers but i only got one fruit from the very first flower on one of the plants. I started catching bumble bees and putting them in the plastic house to pollinate the flowers, but still no results. Any ideas???

Can eggplants become poisoness if left too long after ripening? Mine have become soft and lost there nice shiny lustre and have become dull and have green patches.

I know it's over a year later, but I've been looking for info for overwintering a huge eggplant plant, and saw your question here. Summer '22 I picked up three 5" Japanese eggplant plants from local Tractor supply store, on sale in 3 or 4" pots, for $4 each. I grew them in central MA, each in a 12 or 14" pot all summer. Got some good yield, and they grew to about 18" high, but I decided to bring them inside for the winter to see if I could get more fruit from them. I put them on a south facing bay window, air temp was never much above 68*, I watered, fertilized once (maybe 2x) from October-May, and hand pollinated flowers with a paint brush. Got about 10 fruits, which I thought was pretty good! Nice and tender and sweet. In late May/early June they went outside, (after hardened off properly) planted 1 into 2' tall raised wooden garden box (with tomatoes, potatoes, basil, borage), 1 into a large deep pot, and one in a conditioned straw bale. The pot one failed, the box and straw bale one thrived and are now 3' tall and maybe 2-3' wide. Tons of flowers, fruit, I couldn't keep up. I'm trying to figure out if I can bring one of them inside again (transplant into v. large pot) and get one more summer out of it! So you can probably grow Ichyban Japanese in your zone, just protect from cooler temps, and bring inside if your season isn't long enough.
