I bought six different varieties in a pack from Aldi's and planted them in a deep old drawer in the greenhouse in good multi-compost and have hade two plants produce a couple of strawbs which were lovely, but the rest have 8" high leaves and one or two flowers only. I am planting their runners into 3" pots alongside and pinned down and hope to get a good crop later in the season. I have not fed them in the hope that will force them to produce fruit if they think they are dying and will want to set seed. Only H2o.
