Caring for potted Gerbera Daisies
I live in zone 9, coastal LA. Can my pots be left outside through the winter? What temp should I bring them in for? Right now they are in a flower bed in a sunny spot. We have been receiving lots of rain and the plants have a few dark spots on some leaves. When can they be either repotted or placed in the ground?
First I would protect the pots from excess rain. They could be unable to drain away all the excess water and if the roots sit in soggy soil will develop root rot.
Dark spots could indicate a fungus disease that also can be caused by the damp conditions and lack of air flow.
Gerbera are a frost tender perennial and can withstand temperatures down to 30 degrees F. Any frost will damage or likely kill the plant.
Here is a great article with care information.
