I have ordered a set of mixed perennials from Thompson & Morgan and they arrived this morning, Each seedling is in a very tiny plug. Please can someone advise me (in detail!) what to do next? There is an information leaflet, but as a beginner gardener, I have some uncertainties.
It says to plant them up into 9cm pots - is that one per seedling, or do I put a few seedlings into one pot? Then how long do I let them grow indoors before I start hardening them off, and when is the latest I should be actually planting them in the ground? And finally, will they all not just die over winter?! Thanks for any help.
