Thanks for the replies.
I know it isn't overcrowing, but i'm not sure abut overwatering - how do i

Thank you for the links.
I'll go and follow them up.

BTW I did plant some gourds and they all did very so far (fingers crossed.)

I do know that 2 years ago my seedlings all died because my toddler was into
eating soil, but that is no longer the case.
