If you are growing tomatoes, you are either already enjoying yours or waiting for them to ripen, depending on the variety. Unfortunately, some of you may have had some tomatoes that have been affected by blossom end rot and are no longer edible.
Blossom End Rot
Blossom end rot starts at the blossom end of the tomato, hence the name. It starts out as a small, sunken spot. It continues to spread and cause the fruit to ripen early. So look out for a discolored, sunken, dark spot near the bloom end of the plant. Also keep an eye out for blossom end rot in melons, squash, eggplants and peppers. Identify blossom end rot with these pictures.
What Type of Calcium to Use on Tomatoes?
A foliar sprays containing calcium chloride or calcium nitrate applied directly to the tomato and the leaves around it work great. You may also correct soil calcium deficiencies by applying lime or gypsum if you do it prior to planting. This does take some planning and you will have to have a soil test to see what your soil needs also.
Cultural Controls For Blossom End Rot
Plants need water to absorb calcium from the ground. Be sure to not let the soil stay excessively dry. An even moisture level in the soil will keep blossom end rot away as long as there is calcium to absorb. Also, a good layer of mulch will retain moisture longer.
