I have an easy way to save your geraniums from year to year. In mid September to early October cut back geranium and place container in a large garbage bag in your garage or cool basement for the winter months. When temperatures start to climb up and there is no threat of frost remove plastic bag and place in sun. Saturate with water until you see water coming out of the base of plant. If temperature drops bring back into garage and keep inside until there is no threat of frost. From there it's a piece of cake! Beautiful blooms. This will be my 6th year with this beautiful plant. I have had to change containers twice. Blooms galore!
This is how the geranium looks after the long winter. It has already started to get green in early March.
Getting ready for winter. Cut back plant well making sure to leave some of the plant green leaves on.
Cut back a bit more.
