I bought three strawberry plants which I've had growing merrily in the planter for about 2 - 3 months now...all was going well, all three flowered and started producing berries...the first 3 or so fully ripened but since then, all the others have stopped growing completely!
Two of my plants are now completely floppy despite watering and feeding as I should be (1-2 inches daily, potash weekly), the third is still nice & proud but fruit has still stopped growing...so now I don't have any!!
I've thought about bugs but haven't noticed any of the usual signs etc, I've seen some small, flea-like bugs around the soil and base of the plant but they're around all three plants?
Please help, I've no idea what I'm doing wrong!!
