@imafan, I realize you can't answer HOW to overwinter below lowest temperatures in Hawaii, but could you describe what you do and how the plants respond?imafan26 wrote:Petch is a small thai eggplant; very seedy but good for curries. The fruit is small but the plant was only slightly smaller than the larger eggplant. I guess they could be ok if you are going to prune the eggplant. I put one eggplant in a 20 inch pot and it gets to be between three and four feet tall and just as wide. In the ground it can get over 5 ft tall but I only keep them a couple of years since their production will drop. I know people who have kept their eggplant at least 8 years and the pruned ones are about 3 ft tall but can be just as wide. Unpruned they get bare on the bottom but can get up to 6 ft tall.
Where you are, do they go through a period of dormancy or rest? What are the lowest temperatures? (This will help to determine what temps to keep them) -- BTW I did read elsewhere that some people report eggplants are winter hardier than peppers.... If anyone with colder winters with temps down to near freezing and some frost have managed to overwinter eggplants, I'd love to hear the details.
I've been trying to overwinter one, two, and three test plants for the last couple of winters In the house, and so far I have found them to be extremely vulnerable to aphids and white flies, as well as tomato leafminer moths. Also, one plant that I brought in the house to mature a fruit for collecting seeds died immediately after.
I want to try again this winter, so looking for more information and ideas.
