As soon as 50% sprout the covers should be removed and lights placed 2-3 inches above the tops of the seedlings and left on for 14-16 hours each day. Refer to the growing guide booklet that came with your seed order and also check out this seed starting resource for reference: https://www.floretflowers.com/resources/seed-starting-101/.

Hi BriAnn,
I planted my zinnias and dahlias March 26th. They are in 72 cell trays. They look lovely….just leggy in my opinion. Is it OK to keep them in the 72 cell tray until I plant them in May? Will they get stronger? This is my first time planting seeds. It is very exciting. I have learned a lot. Just want to make sure I am doing the best things for my babies!!
Thank you!!

My Floret Original Dahlia seeds sprouted 32 out of 36 cells 5 days and they look so fragile. They are too tall for the covers in the seed cells so I took them off a few days ago and they look fragile. What do I do with them next. I don’t want to mess this up! I live in Zone 9.

In reply to Casey. They may need to be potted up if they are getting root bound. A little fertilizer like diluted fish emulsion may help for a boost of nutrients. I hope this helps!

I started my floret dahlias from seed about 4-5 weeks ago. They have 3 sets of leaves and range from 3-8 inches tall, but many of the bottom leaves are yellowing. What can I do? Thank you!

I am just amazed. I didn’t know until this article that I could even grow dahlias from seed. I got my order in to Floret, and planted your seeds a week later. Every single seed came up within the first week. They are now over two inches tall and I’ll have to raise the grow lights probably any day now. I can not wait to put these in the garden. Thank you for all your incredible garden expertise. My gardens have been so enriched by Floret. 7b Northwest Georgia.

I recently started dahlias from seed for the first time and found something interesting that differs from your article so wanted to share in case it is useful for anyone. I did not keep them cool – they were on heat mats in a warm room (75F+). I had 80% germination in less than 3 days.

Thanks for all the great free resources!

In reply to Terry durkin. Check the soil and when the tops begin to appear dry then it's time to water them. Also, be sure to have the lights set several inches from the tops of the seedlings.

I am terribly late starting my seeds here in zone 8b… I should have started them at least 4-6 weeks ago. What would you recommend for starting seeds so late in the season? Outside in pots maybe? Or still indoors until they are ready to be planted out? Excited to try dahlia seeds for the first time! Thank you!
