I got my tomato,carrot, and pepper seeds to germinate, but it's been 20+ days and my eggplant seeds wont germinate! They are the oval, white variety, is there special requirements to germinate eggplant seeds? (my first time trying to grow it).
From what I've obsersved over the years, eggplants do actually tend to take a bit longer than the rest. Sometimes up to two weeks. Eggplants are my faaaavorite veggie! I'm growing eight different kinds by seed this spring. I also know they require extremely warm temperatures to germinate. 75F+, and a lot of light. Try putting them in the window sill and keeping them moist and lightly covered with a thin layer of compost.
Sometimes a considerable change in temperature from day to night can trigger germination. Warm days with light, cold dark nights. I found this with cleome especially. I'm not sure if it would work with a solanacea
