Blossom End Rot on Tomatoes

Blossom End Rot

The first tomatoes to ripen in Tri-Valley gardens are often marred by a leathery brown patch of brown known as blossom end rot. Usually, blossom end rot is caused by a calcium deficiency. Spraying Monterey Foli-Cal will quickly provide the necessary calcium to reduce or eliminate this problem. You can also reduce blossom end rot by growing a larger set of roots.

Early in the season, tomato root systems are not large enough to pull an adequate supply of calcium from to soil into the leaves to meet the production needs of the plant.  Deep infrequent watering throughout the projected root zone of the plant will help establish a large network of roots to pull in calcium, other nutrients, and water from the soil.

Deep watering provides a large reserve of water in the soil below the plant. Infrequent watering forces the roots to grow larger in search of water. Short, frequent watering can hinder this process.

Get ahead of the game by spraying the leaves now with Monterey’s Foli-Cal. Foli-Cal is designed to supplement the plant’s calcium needs with foliar feeding, reducing or eliminating the condition on tomatoes.

Apply at 14-day intervals throughout the growing season.
