My Eggplants are growing good. Keeping my eye some pests and squishing them. But the fruit seems to have a strange growth effect on them. The bases seem to be a green colour and the fruit seems to have like growth spurt makes on them. Can you please tell me why this is happening and what I can do to stop the marks occurring?

i planted my eggplants late december , it looks healthy, has lots of flowers but does not fruit. what do i need to do to fix this problem?

This is most probably due to a lack of pollinators (bees etc). Try planting some bee attracting plants. You can hand pollinate in the meantime.

I think what you are describing is not actually an Eggplant but a related species. Try looking up Solanum mauritianum. It is an invasive weed, I had one recently and immediately thought it looked like an Eggplant. Do not eat! it is posinous.

My eggplant is mature and has lots and lots of flowers and leaves but no fruit. What am i doing wrong?

Hi Anne, The only thing I can suggest is sprinkling some sulphate of potash around the plant and watering it in. Alternatively, you could bury a couple of bananas (with skin) around the plant but I'd suggest the concentrated sulphate of potash. As you probably know, potassium promotes healthy flower and fruit growth in most plants. Nitrogen promotes new stem and leaf growth so its possible you have too much nitrogen in the soil (using cow or sheep manure?) and not enough potassium.

They could be sun burnt. Even in winter sun strong enough to burnt the tender skin of your eggplants

You need to cross-pollinate manually. Bees are the pollinators. We had bees in the garden & fruit on the eggplants, then no bees & no fruit. The flowers are hermaphrodite. Pick a freshly opened flower from one bush & gently brush the stamen against flowers on other plants.

I have two Asian eggplant bushes which look like they are coming to an end in terms of producing fruit. Is there any chance I could prune these back and see if they regrow next spring? Also, what to do about the nasty grubs that get in and make tunnels, along with lots of black stuff. Sometimes you don't even know they are there till you cut the eggplant open.
