Hi Gerry, I sowed seed in trays about 2 weeks ago.Lots have germinated but a good no. are falling over and dieing when about 15-20mm.high. I am keeping the compost damp. Any ideas?
Seedlings should be pricked out into new trays or pots as soon as they are large enough to handle .. when the seed leaves have expanded, Usually just a week or so after germination.
