Blossom end rot

Tomato Care

Posted by John Fulton -

With the widely fluctuating amounts of rainfall, blossom end rot is definitely a possibility. It has even started on some container grown tomatoes. The best solution is to mulch tomato plants to help even out the moisture supply, and help keep the roots cooler. This problem is caused by uneven calcium amounts in the plant. Addition of lime when you see the problem usually isn't as effective as evening out the moisture flow for the plant by mulching. Any material will do (grass clippings, straw, commercial mulch, etc.) with two inches being adequate and four inches being better. You may have to compensate with a small amount (emphasis on small) if you use items which decompose quickly – such as grass clippings.
