Hi,

I've got 2 pots of livingston daisies which have grown to a nice full size
(and have been so for approx 2 months), but still no sign of any flowers.

They have been well watered and get approx half sun/half shade during the
day. Anyhting obvious I could be doing wrong?

Try giving them dry conditions in full sun; don't feed them.

Janet
