Causes and Solutions for Yellowing Strawberry Leaves
During strawberry cultivation, yellowing leaves often occur, affecting the plant's normal growth, which in turn leads to reduced yield and economic losses, so timely prevention and control are needed.
Causes of yellowing strawberry leaves
1. Too great a difference between dry and wet conditions; after the plant goes without watering for a long time, the leaves first wilt and then turn yellow. There is also the case where, after a long period without watering, a large amount of water is suddenly given, and the plant simply cannot adapt, causing yellowing.
2. Changes in environmental temperature, such as suddenly moving the plant from a greenhouse to an air-conditioned vent, can cause yellowing and leaf drop. Lack of sunlight affects strawberry photosynthesis, and can also reduce leaf transpiration, causing circulation problems in the plant.
3. Yellowing and leaf drop caused by a lack of trace elements or excessive fertilization.
4. Yellowing and leaf drop caused by metabolism and disease, but it will not cause large-scale leaf drop.
Solutions for yellowing strawberry leaves
1. Strawberry watering should mimic nature, with sunny days and rainy days (do not water unless dry), and remember to water moderately.
2. Place it in a sheltered spot with plenty of sunlight for cultivation.
3. If light and watering are normal, yellowing leaves are caused by a lack of fertilizer. Apply some fermented rice-washing water or evenly apply 20 granules of compound fertilizer per month under the soil at the edge of the pot.
4. If strawberries are planted on a large scale, weeds should first be removed and soil-dwelling pests eliminated. A 1000-fold dilution of 50% phoxim emulsifiable concentrate can be sprayed (moistening the soil layer 5-6 cm deep) to control white grubs, mole crickets, and cutworms. If growing them yourself, remember to regularly prune dead leaves or use insecticides reasonably.
