Petunia and gladioli from last year

Eustace

I have a few petunia plants from last year which flowered profusely last year still looking green and healthy. They are in a pot placed just outside the front door near the wall. Will they flower again this year? Or should I dispose them off? 

I have a few gladioli plants also in pots, which didn't flower last year, still with green leaves. Do I need to trim the leaves away so that they can reshoot this year? Thanks in advance for your help.

IThe petunias might flower again if they don't get killed by frost but they tend to get straggly. If you want to give it a go, I would leave the top growth on until spring, after the last frost (or your best guess in your area) then cut them back quite hard and repot in fresh compost. If they regrow they should flower, and you could also take cuttings if you like.

I would leave the gladioli alone for now. Some people lift and store them after the foliage dies down. I leave mine in the ground and reflowering is a bit hit and miss. It's probably too cold here for them to overwinter successfully in the ground.

I'm not too far away from you Jenny, (Wakefield) and my gladioli have been in the ground for 5 years now, never been lifted and stored and have flowered every year.
