Blossom- End Rot
Posted on 6/2/25 at 9:13 pm

I have been having trouble with blossom-end rot on my tomato plants. I know this is caused by calcium deficiency, but don’t really see calcium supplements.
Would bone meal work for this?
Something better?

Calcium Nitrate is available at every garden center. Bone meal if you don't like chemicals.

It is a calcium deficiency in the tomato. It is usally caused by uneven watering, not because there is no calcium in your soil. Water more.

This. Focus on being more consistent with your watering. Irrigating my garden effectively eliminated blossom end rot on tomatoes.

I had some tomatoes that got this last week and we sprayed Ferti-Lomé Yield Booster, stopped it immediately . 2 TBS per gallon, bottles says ,stop blossom end rot ,

It’s ultimately a watering issue as has been said but I do also add gypsum when transplanting as an insurance policy. It’s a cheap slow release form of calcium that also amends soil, so not really any downside.

Years ago I tried the spray, didn't work for me.

I never had luck with the spray, either. I think it is mostly hokum at this point, at least for blossom end rot.
The best thing I found is using soaker hoses at planting and mulching with straw. When I grew a lot of tomatoes I kept straw on them from the time I planted them and used a single wire stretched the length of the row over the tomatoes. We used a single long piece of twine in a V shape as a trellis like to keep them off the ground. We would prune most of the suckers and force growth to the main branches, allowing more airflow through the rows. Good airflow and consistent watering can prevent most issues you will have with tomatoes and peppers.

Interesting….i have had to water very little this year because it has rained so much to this point. Typically, if the plants aren’t wilting, I don’t water.
