Need suggestions for tweaking 511 for watermelons
Last year I grew cantelopes and watermelons in decent sized containers, in a standard 511 mix. The watermelons didn't perform so well. Vines were short and melons small. I thought this was a little odd since watermelons were supposed to be a little more tolerant of acidic soils than cantelopes. Any suggestions for improving the 511 mix for the watermelons? Thanks.
