Blossom End Rot
This common garden problem is often caused by a lack of calcium and/or uneven watering. Learn how to identify and cure blossom end rot here.
A serious disorder of tomato, pepper, cucumber and eggplant, blossom end rot is an environmental problem (not fungal) caused by insufficient levels of calcium during fruit formation. This common garden “disease” is often brought on by rapid growth from too much fertilizer, high salt levels, drought or uneven soil moisture.
Blossom end rot occurs on both green and ripe fruits and is identified by water-soaked areas that mature into sunken, brown, leathery spots on the blossom (bottom) end. In many cases, secondary pathogens, which appear as a black, fuzzy-like growth, attack the affected area and cause complete rotting of the fruit. Blossom end rot will not spread from plant to plant.
Since blossom end rot is physiological in nature, fungicides will not work as a control measure. We recommend the following:
• Choose resistant vegetable varieties whenever possible.
• Mulching plants will conserve moisture and provide a more uniform water supply.
• Avoid using high nitrogen fertilizers, which accelerate vegetative growth and reduce the uptake of calcium by plants. A large selection of balanced organic fertilizers are available at Planet Natural.
