Blossom end rot

(calcium transport disorder) · Podridão apical

What you see

Sunken leathery dark patch on the BOTTOM of tomatoes and peppers. Not an infection - a calcium delivery failure inside the fruit.

Conditions

Erratic watering: drought then flood stops calcium reaching the fruit tip. Pots and hot spells are prime territory.

Treatment

Remove affected fruit; fix the WATERING, not the soil - the next trusses will be clean.

Prevention

Steady, deep, regular watering; mulch; avoid excess nitrogen; no need for calcium sprays in most soils.

Months: not recorded
