Poor plants are doomed!
I see this a lot, summer bedding plants bought for the garden mostl only to be exposed to the frosts that are coming soon!
These are Pelargonium, and there's loads of them (begonias too), all doomed to turn to mush.
And a lot of people buy them thinking, oh they must be annuals anyway!
Plus the council plants hundreds of summer bedding and come August theyre all dug up, still healthy, and thrown out, such a waste of plants, and money!
