I've grown some agapanthus from seeds and they are now 3 blades of leaf strong. I put them into 9cm pots about a month ago and they are on a sunny windowsill.
What do I do with them now ? Do I start hardening them off outside for a few weeks and them move them outside ? How long do I leave them inside for ? I planted the seeds in Oct & end of Nov (2 lots).
Any advice gratefully received. Thank you.
