End rot

by Bill lewis

Is there a cure for end rot on tomatoes or is the whole plant a loss? I understand once a tomatoe has it that tomatoe is gone but can I fix it so the rest of the tomatoes will be healthy?

----------------------------------------------------------

Answer from Stella/Simon:

In blossom end rot, a dry sunken decay develops on the blossom end (opposite the stem) of many fruit, especially the first fruit of the season.

This is not a pest, parasite or disease process but is a physiological problem caused by a low level of calcium in the fruit itself. There is no cure for blossom end rot, only prevention. Try a different well-balanced nutrient solution. We recommend GH Flora nutrient solution.

Hope this helps!

Crushed eggshells may be worth a try...
by: Char

I have read that using a couple of crushed eggshells helps prevent blossom end rot for soil-grown tomatoes. (Crush a couple and mix in with the soil when you transplant.) The eggshells have some calcium. You'd want to be sure to clean them well so there is no protein residue from the eggwhite. I haven't tried it for hydroponics, but it seems worth a try. Would be interested in hearing if any others have tried that.

End rot
by: Ann

My tomatoes have the brown end rot, too . . . frustrating! I was advised by our local hydroponics store to add more calcium/magnesium (Cal-Mag brand) every time I add water. I also wonder if the pH might not be set right and blocking out some of the nutrients.
