Strawberry Leaves Drying Up: Causes and Solutions

During strawberry plant growth, leaf drying is a common phenomenon; dried leaves lose normal photosynthesis, so healthy plants accumulate less nutrition, which is unfavorable for improving yield and quality. So what causes strawberry leaves to dry up? Follow the editor to learn about it.

1. Fertilizer burn

Fertilizer burn is one of the main causes of strawberry leaf drying, and this phenomenon is extremely common. One cause of fertilizer burn is that farmers do not properly control the amount when applying, applying an excessive amount at one time; another reason is that to save effort, multiple fertilizers are mixed together, which increases the fertilizer concentration; the third is that the fertilizer applied is unrotted organic fertilizer.

Solution: In response to the causes of fertilizer burn, take targeted preventive measures. When applying fertilizer, strictly follow the usage and dosage on the fertilizer packaging instructions, and it is best not to increase the concentration without authorization; do not mix multiple fertilizers together. When necessary, it is recommended to calculate the usage amount of each fertilizer and increase the amount of water used. For base fertilizer, be sure to choose fully rotted organic fertilizer. After fertilizer burn occurs, irrigate with a large amount of water to dilute the fertilizer solution concentration, which can help relieve it.

2. Calcium deficiency

Calcium deficiency is also one of the causes of strawberry leaf drying. Its characteristics are wrinkled leaves, or wrinkled with a light green or light yellow boundary line, leaf chlorosis, brown spots on the petioles of diseased leaves, and often a syrup-like water exudate.

Solution: Strawberry calcium deficiency can be quickly relieved by spraying chelated calcium on the leaves. In addition, alkaline soil can also block root absorption of calcium, so the soil pH can be appropriately adjusted. In addition, supplementing organic fertilizer, microbial inoculants, etc. can regulate soil permeability and improve soil structure.

3. Root suffocation

After heavy rain, water accumulates in the field, and strawberry roots are soaked in water for a long time. Root respiration is blocked, and over time the alcohol produced poisons the roots, causing root damage. After root damage, the absorption of nutrients and water is blocked, ultimately causing stunted plants, yellowing leaves, and drying, and in severe cases dead seedlings.

Solution: For seedling raising, choose plots with good drainage and irrigation, keep sowing ditches unobstructed, and especially drain accumulated water promptly after rain. At the same time, clean up the planting and remove the silt around the seedling heart and rhizome.

4. Herbicide damage

Weeding during the seedling stage can easily cause herbicide damage to young seedlings. Strawberries are relatively sensitive to chemicals; some chemicals will cause leaves to turn yellow after use, and some may even cause seedling death. There are mainly two causes of herbicide damage: first, the chemical concentration is too high; second, a chemical to which strawberries are sensitive is used.

Solution: When using chemicals, be sure to follow the packaging instructions, and it is best not to mix them. For herbicides, try to choose those that have been used on strawberries and have little or no harm; for those not used before, test them first before promoting large-scale use. After herbicide damage occurs, spray clean water, and gibberellin and brassinolide can also be sprayed to relieve it, but pay attention to the concentration as well.
