| I bought a bottle of Rot Stop because my tomatoes are rotting right when they ripen. Am I supposed to spray on the leaves or the roots? And how much do I use? |

Quoted:
I had it and applied a crapton of lime to the soil. Seemed to work. Edit: the lime took a few weeks, but now I have no more end rot. Where did you apply it to? I have the same problem. jcncc was kind enough to post this in my garden thread. Maybe it'll help you guys. Quoted:
Calcium/Magnesium deficent. Spray with a calcium formula like Green Light or Ortho and toss in 1/4 teaspoon of Epsom salts per gallon. Spray late evening and rinse plants early the following morning. spray three times during the life of the plant about every 30 days. Quoted:
Thats the ticket. Also pick up a jug of fertilome Triple action plant spray. It contains a fungicide, Mitacide, Insecticide. Once again mix to the lowest level and spray every 30 days. Allways remember to rinse your plants the following morning. never mix the CalMag solution with anything else it is a seperate operation. A regular spray program along with dumping composted manure and such is all you need. Remember to add compost at least 45 days PRIOR to planting. Sorry to yell but that is extremly important.

End rot is caused by calcium deficiency. I have read that lack of adequate water can be a problem as well. Your soil might have enough calcium but without steady water the plant cannot effectively absorb enough. I can vouch for Lime working but like another person stated it takes a while. I have always have end rot on larger tomatoes but Roma, Cherry and grape tomatoes do really seem to have that problem around here. My mother used some of anti rot spray stuff last year and in guessing apply to the roots. |

This is especially true with high PH soils as it will prevent iron and calcium uptake. |
