Reuse of ProMix BX in grow bags

Yak54 · December 23, 2020

I'm wondering what the collective Tomatoville knowledge and experience is about using ProMix multiple times in grow bags for growing tomatoes & peppers. It seems that the first year I got little disease and very productive tomato plants and the second year reusing the same batch of ProMix I got more disease and less productivity. Fertilization and watering being very similar from year to year. Now I know there are many factors (like weather) that could cause this situation but I am relatively new to growing in grow bags and ProMix (5 yrs) and wonder what you guys and gals have learned about reusing ProMix from year to year. I should say that I soak the empty grow bags in a diluted bleach solution at the start of every growing season in an attempt to sterilize the grow bags before re-filling them with the ProMix
