I've got Impatiens seedlngs! Now what?

lewdog(4)February 13, 2012


I am trying my darndest to grow impatiens from seed. This is my first attempt. At this point they have germinated (just this morning). I have them uncovered under florescent lighting with heating mats in my basement. They are in very very moist soil. I followed these instructions from Iowa State University: http://www.ipm.iastate.edu/ipm/hortnews/1996/2-9-1996/impa.html

My first question is, do they continue to need 24/7 lighting before the 7 - 10 day transplanting into the larger cell packs?

If anyone could help me out... that would be so awesome!

Take them off of the heat mat. Heat is only needed for germination. I would leave the lights on 12 to 16 hours a day with the lights being just a few inches from the seedlings. If you worry that the soil is too wet you can put a fan on them set on low speed. It will dry it up and also help make stronger plants.

Thanks franknjim!!!

I'm taking them off the heat mat today cause I think the germination process is done (about 75%!!). I plan on transplanting the junior impatiens in six pack cells with a non-soil mixture. They will be in my basement with fluorescent lighting for 16 hours each day. I plan on covering them with plastic lids. I hope I have this right.
Again any thoughts and assistance would be much appreciated!! Again, thanks franknjim!!!!!

They won't need to be covered once they are up. Covering them is to keep the humidity high during germination.
