Use of ammonium calcium nitrate
« on: May 15, 2020, 03:24:54 pm »
In the prevention of blossom-end rot in tomatoes, would use of ammonium calcium nitrate as a foliar spray periodically, in addition to using it as "the snack" through the water fill tube, be helpful, unnecessary, or counterproductive?

Thanks.

Calcium uptake occurs through the root system, foliar calcium is ineffective.  One tsp calcium nitrate is better than the ammonium form,
Why Google, when you have me?
