Calcium against Blossom end rot of Chillies and Tomatoes
Recognize the problem
end rot of chillies and tomatoes is a problem that is caused by calcium
deficiency. During blossom end rot, the skin of the fruit becomes fragile.
The skin at the end of the fruit where the flower grew splits, rots and
develops a circular spot. The rot causes the skin of the fruit to turn
greenish brown to black. As the rot expands, it allows other diseases to
enter the fruit which affects the production of the crop.
end rot develops when the fruit does not receive enough calcium. It may
develop when the plant is deficient in water because this prevents sufficient
calcium from reaching the end of the fruit.
sure the crop is well watered so that enough nutrients get to the whole plant
a layer of mulch to help maintain even moisture
24kg Potash / acre so that fruit becomes healthier and less susceptible to
the foliage with calcium chloride when symptoms first
