How to Save Flowers After Waterlogging? A Detailed Guide to Practical Remedies
Remedial Measures for Flowers After Waterlogging
Prolonged rainy weather or excessive irrigation, waterlogging in low-lying areas, or clogged drainage holes at the bottom of flower pots can all cause waterlogging and oxygen deficiency, leading to flood damage in flowers: roots turn brown and rot, leaves turn yellow, branches and leaves wilt, and leaf drop, flower drop, and dead branches occur; over time, the entire plant dies. To reduce losses from flood damage, remedial measures should be taken promptly after flowers are waterlogged.
1. Drainage. For flowers planted in the ground, dig ditches to drain water. For potted flowers, clear the drainage holes at the bottom of the pots, drain the accumulated water from the pots, and move the pots to a rain-sheltered, well-ventilated, dry place to reduce soil moisture in the pots. After waterlogging, the root system of flowers is damaged to some degree, and its absorption function declines. To maintain a relative balance between root water uptake and leaf transpiration, while strengthening soil drainage, spray the leaves with clean water or apply an antitranspirant to reduce plant water loss and promote a return to normal growth as quickly as possible.
2. Cultivation. Soil compaction after water accumulation is the cause of oxygen deficiency and root rot. For waterlogged flowers, cultivate and loosen the soil in time to enhance aeration and meet the roots' oxygen needs.
3. Soil replacement. Scrape away the wet surface soil around the roots and replace it with dry soil. For potted flowers, spread plant ash or dry soil on the pot surface to reduce the water content around the roots and promote recovery of metabolic function. For potted flowers that have been waterlogged for a long time, knock the plant out of the pot together with the root ball, place it in a cool, ventilated place to let it evaporate moisture, and after three or four days, when the water content returns to normal, repot it for care.
4. Sun protection. When long rain suddenly clears, place the pots in a cool, ventilated place to prevent sudden exposure to strong sunlight. This is because after waterlogging, the root absorption function of flowers is markedly weakened; sudden exposure to strong sunlight would intensify transpiration and water loss from branches and leaves, causing wilting.
5. Fertilizer control. After flowers are waterlogged, the roots are damaged to varying degrees, and their absorption function is significantly reduced. At this time, no fertilizer is needed; otherwise, it will accelerate the death of the plant. Wait until the root system regains normal absorption and metabolic function before fertilizing, applying dilute fertilizer frequently, and the concentration must not be too high.
