Calcium and boron corrector

Prevents cracked fruit and blossom-end rot in tomatoes and peppers.

What it's for: Water-soluble corrective feed with 28% calcium and 1.5% boron, complexed with amino acids. Improves firmness and fruit set, and prevents cracking and blossom-end rot. Calcium and boron move poorly in the plant, so deficiency shows first in young tissue.

Best for: Tomato, pepper, watermelon, melon, apple — anything that cracks or rots at the tip.

When to apply: At fruit set and during fruiting, and whenever needed.

How often: Every 2 months in spring and autumn; every 15 days in summer.

Dose: Watering 5 g/l. Foliar spray 1.5-3 g/l.

How to apply: Dilute in irrigation water or spray.

Worth knowing: Blossom-end rot is nearly always an uptake problem rather than a lack of calcium in the soil — irregular watering is the usual cause. Fix the watering too.
