Indian Blanket Flower from seedd #926180

Asked March 17, 2026, 3:07 PM EDT

These seeds germinated very well, now they have the first true leafs. They average 1-2 inches in height. Do I transplant now before their roots entangle much and still keep them inside in a sunny place until plant out time or is it better to leave just clustered where they germinated?

Hi Laurie, 

Some of the larger seedlings could be transplanted now although I think waiting until they are bit larger would be better (2 to 4 true leaves).  I would keep them inside still as freezing nighttime temps are in the forecast.  The average last day of frost here is about June 1st.  It's best to wait until the danger of frost has passed to plant or be ready to protect plants with row cover. 

I have attached a PDF on seed sowing, transplanting and hardening off.  The seedlings will need to be hardened off before planting outdoors. 

Please reach out if you have further questions!
