hello this is my first posting on here and i hope somebody can help. my
tomoatoes in the greenhouse are still not flowering although some are
about 15 inches high. i'm concerned i planted them out too late - last
weekend. i am however near glasgow so the greenhouse even now still
drops to 5-10 degrees at night. will they eventually flower? i'm hoping
they will i've planted out 30 of them!

Are you overwatering them?
