Eggplant is another member of the Nightshade Family like tomatoes and peppers that benefit from a head start indoors.
Indoor Sowing Tips:
In order to germinate, eggplant seeds prefer a temperature between 75 and 90°F. Based on this, start the seeds under grow lights and with a seed heat mat underneath the seed tray.Â
Eggplant seeds should be planted 1/4″ deep around 2 months before the last average spring frost under grow lights.
While I initially water the seeds from above until the seeds germinate, I switch to water from below in the seed tray.
Transplant the eggplant seedlings to a 4 inch pot in the grow room once there are a few sets of true leaves and continue to water them from below in the seed tray.
Don’t forget to harden off the seedlings before transplanting in late spring or early summer. Keep in mind that eggplants love warm days and nights which is why they are considered a warm season annual.
Space eggplant seedlings about 1 to 1 1/2 feet apart. Since I typically grow the smaller eggplants, I space them 1 foot apart.
Growing Tips:
If you plant your eggplant seedlings too early, you might want to consider using pvc hoop tunnels and some lightweight garden fabric. Also, I would recommend using mosquito netting until your eggplants start taking off to keep away flea beetles and aphids in case they are a problem in your area.
Provide compost when planting and plant food that is higher in calcium and phosphorus once a month or as needed.
Keep eggplant seedlings and plants moist but not soggy by using a drip system.
Support eggplants with stakes and stretch ties like Vigoro in case it gets too windy.
