Handling Method for "Rotting Heart" in Clivia Miniata
A little plant knowledge: an introduction to Clivia Miniata from the Flower Clinic, the handling method for "rotting heart" in Clivia Miniata. The following is a detailed introduction for you.
The "rotting heart" of Clivia Miniata is caused by dirty water entering the leaf cluster during the high-temperature season, leading to the necrosis of the heart leaves of the plant. Different rescue measures can be taken based on the severity of the heart leaf necrosis.
If only the central part of the heart leaf is rotting and necrotic, it can be moved to a shady place and watering should be stopped for 3 to 5 days to dry the potting soil. Then, use a disinfected single-edged blade to cut off the necrotic part, noting that the cut surface will secrete a large amount of sticky sap. The pot can be tilted to prevent the sap from flowing back into the heart leaf cluster. Use clean medicinal cotton to absorb the exuded sap or sprinkle crushed oxytetracycline tablets as a powder on the wound. Keep the potting soil slightly moist, do not spray water on the leaves for 1 to 2 months, and commonly wipe the leaves with clean damp cloth to keep the leaf surface clean. After the coolness of autumn, it can regain its vitality.
If multiple heart leaves rot from the base of the stem, the plant should be removed from the pot, the old soil shaken off, and the roots washed clean. Then, thoroughly remove the rotted base of the leaves or the rotted part where the leaf stem joins, and use a 75% alcohol cotton ball to wipe the rotting heart wound and its surroundings clean multiple times. Alternatively, soak the cleaned rotting heart part of the plant below the rootstock in a 0.05% to 0.1% potassium permanganate solution for 1 to 2 hours, then place it in a cool place for 12 hours.
Then, plant the disinfected and dried plant in a new pot with plain soil, making sure the planting depth only buries the root neck, and the base of the leaf cluster must be exposed outside the soil. Water the roots slightly but not too moist to avoid inducing root rot.
Place the plant in a cool and semi-shaded place after repotting, making sure to set up a rainproof shed to prevent rain from entering the leaf cluster and causing the heart to rot again. Keep the potting soil slightly moist and avoid spraying water on the leaves. Use a damp cloth to wipe off the fine dust adhering to the leaf surface. No matter how severe the heart rot is, as long as the auxiliary bud primordium at the junction of the stem and root has not been completely destroyed, after 1 to 2 months of careful care, new buds will grow from the stem. When the new bud leaves grow to 6 to 8 centimeters in length, normal watering and fertilizing can be resumed. After 1 to 2 years, the plant with a rotting heart can be expected to sprout and bloom again.
