I have succeeded (finally) in growing over 100 strawberry plants (several different varieties) and they are very healthy plants, very productive and other thand! I few duds produce gorgeous, juicy berries...but all for naught. They are simply tasteless and soooo tart! I performed a soil test and not surprisingly, the soil is much too alkaline. I suspect this may be the cause? If so. Can I fertilize them with say Miracle Grow acid fertilizer to make them sweet? I have lots of natural compost in the bed and I have removed hundreds of runners. Help??
