can anyone explain?
I sowed some Nicotiniana lansdorffii [ lovely plant if you haven't tried it ] 14 days ago. Sown in a propagator, in my usual Perlite and John Innes No. 1, and nothing has germinated.
4 days ago I decided to sow some more, same packet, same compost, and today they have germinated.
Love cliff richard but please don't tease
