To treat blossom end rot, insert calcium carbonate tablets or anti-acid tablets directly into the soil below the plants or water plants with a liquid fertilizer that is high in calcium. To prevent blossom end rot from occurring in the first place, make sure that the plant gets plenty of calcium and that the calcium does not get tied up in the soil.
Blossom end rot is a common condition in plants, such as tomatoes, eggplants and chili peppers. It appears as a darkened or blackened area on the bottom of the young fruit and gets larger as the fruit grows. Disease is not the culprit of this condition; it simply occurs due to calcium deficiency. To prevent blossom end rot and treat an existing problem, run through the following steps.
- Adjust the soil pH level
- Use the right fertilizer
- Water the plants properly
- Add additional calcium
Alkaline soil can tie up calcium in the soil and prevent the plant from absorbing the mineral. Ideally, the soil should have a pH level of around 6.5. Use a soil testing kit to determine the pH levels of the soil. Balancing the soil pH level can prevent blossom end rot from occurring and helps manage an existing problem.
Use a fertilizer that contains calcium. Avoid adding too much nitrogen, and choose nitrate nitrogen rather than ammoniacal nitrogen when using nitrogen-based fertilizers.
Changing moisture conditions can cause stress in the plants, so it is important to avoid excessive dryness or excessive moisture. Water plants regularly and ensure that the soil is properly drained. Add mulch to the base of the plant to help prevent excessive moisture.
Spraying leaves with calcium chloride can help treat a serious problem; however, plants to not easily absorb calcium through their leaves. To give an instant boost of calcium that the plant can easily take in, insert calcium carbonate tablets or anti-acid tablets into the soil near the plant's roots, as plants can easily absorb calcium through their roots.
