Living down here in the Tampa Bay area of Florida means dealing with frequent heavy rainstorms from now until September or even October. The potting soil I mixed up this year holds water much longer than my mix from last year. I am concerned that the root zone will never really get a chance to dry out between rain events. Has anyone experienced this problem before? How have you dealt with it? Should I simply pull the plants, mix in additional perlite, and repot to ensure fast drainage?
