A combination of water stress and calcium deficiency within the plant promotes blossom-end rot
But it's best to water before the onset of such stress: it can make plants lose leaves, vegetables turn bitter, tomatoes develop blossom-end rot
, fruit trees drop fruit.
Keep on the lookout for blossom-end rot
a soft, dark brown blotch on the bottom of a tomato.
Keep the watering even to avoid blossom-end rot
and, apart from some support, you should restrict the plant to give about four fruits.
is another condition caused by uneven supplies of available water during fruit development.
Cause Blossom-end rot
happens with uneven watering or plants having trouble absorbing calcium from the soil.
From my experience, the main cause of blossom-end rot
is an insufficient supply of lime (calcium) from the beginning of the plant's life in the garden.
A: Blossom-end rot
is caused by lack of calcium in the fruits.
3 Lack of calcium - often experienced when plants are too dry to absorb it - causes distorted leaves, spots and cracks on fruit as well as blossom-end rot
, on the other hand, is more likely to occur in plants grown in open ground.
Calcium prevents blossom-end rot
, a common tomato disease.
If you do, the base of the fruit is likely to split or the tomatoes may develop blossom-end rot
- a dry, hard brownish coat at the base of the fruit which will ruin them.
