IS it OK to keep planting Geraniums in the same border every year? I ask because a couple of years ago I had a marvelous display with loads of flowers, Last year Nothing, even though I planted NEW plants and fed them!
There's a theory that you shouldn't plant the same plants in the same soil every year because each plant type takes specific nutrients from the soil and constant use will impoverish the soil. I don't know what you fed them with, but if you really want to try growing them again I would try digging in lots of fresh compost or old rotted manure, which will hopefully provide some fresh nourishment.
