Which plants are you asking about?

He! He! Try adding a picture also what are the plants called ;o))

Hi I was on a page featuring Agapanthus so these are the problem plants for me. I have sown neighbours seeds and they have come up like grass shoots but as soon as they are in the soil they disappear. Even two ft high flowering plants disappear overnight. Help please

Molluscs (unless you are plagued by rabbits). Happens to ours too. We do not plant Agapanthus out in the garden, instead we put them in pots and put the pots up where, hopefully, they cannot be reached.

Thank you yes that makes sense I shall try it
