Hi Mo. Blossom End Rot is the most common problem with tomato plants. It's caused by a calcium deficiency. Adding lime to the soil in the Fall is the easiest answer to your problem. In the meantime, sprinkle egg shells in your garden. That will help. Good luck Mo.
Hi Mo: Sometimes tomatoes can be so cranky! They will get spots if you over water them or under water them or don't give them what they want. If you mix 1 teaspoon of Epsom salt with 4 cups of warm water and spray your plant, then spray again in 10 days, you should be o.k. Stick your finger into the dirt. If it's wet when you are up to your first knuckle, it doesn't need any water. If it's dry, give it a drink. Good luck
Thanks all! The Epsom salt solution is great, does that give calcium to the plant? I will definitely to the egg shells!
Also if it doesn't any idea for an emergency quick simple easy calcium spray or something?
Hello. I don’t see a photo, for the best local professional advice
I would highly suggest contacting your cooperative extension. These offices are manned by volunteer master gardeners on site there waiting to answer the communities questions that know your local situation quite well.
Master gardeners are required to volunteer back designated hours ( plus continuing education) each year to maintain MG certification -this community outreach and education is their goal.
If your office is closed....there Might be alternative online venues like Ask an Expert as well as emailing your local master gardeners extension office for their guidance.... in a non contact manner.
