Looking for some wisdom please!
I bought a pre-selected tray of plants at B&Q at the end of spring which were a mixture of trailing lobelia, geraniums and petunias. They've done brilliantly for what was about £12 I think.
Thing is, I can't remember if they were annuals or perennials so I'm wondering whether to pull them all out of the pot they're in when they stop flowering, or to expect them back next spring.
Can anyone advise please?
