How to Prevent Strawberry Seedlings from Dying in High Temperatures in Summer

How to Prevent Strawberry Seedlings from Dying in High Temperatures in Summer

Strawberries prefer cool climates and are not tolerant to high temperatures and drought. The suitable temperature for growth is around 15-25°C. If the management is not proper during the hot summer season, large areas of seedlings are prone to die, which significantly affects the yield. So, how to avoid the death of strawberry seedlings in high temperatures during summer? Let's find out.

1. Irrigation to Prevent Drought

In summer, the high temperature accelerates soil and plant moisture transpiration, leading to drought. Therefore, timely irrigation to prevent drought is essential. The irrigation water should reach about 2/3 of the ridge ditch without flooding the ridge surface. If the seedbed is waterlogged, drainage should be done promptly. It is advisable to water in the evening. Depending on the actual conditions of the plot and consecutive sunny days, irrigation is generally required every 3-5 days.

2. Proper Shading

The intensity of summer sunlight is high, which should not expose strawberries to direct sunlight. For outdoor planting of strawberries, timely installation of shading nets is necessary. Adjusting the light exposure can be done by covering the shading nets in the morning and uncovering them in the afternoon. Starting shading at around 10:30 or 11:00 on sunny days when the temperature is particularly high is recommended, using shading nets with a light transmittance of about 50%.

3. Directional Trailing

Generally, in early May, when the daughter plant seedlings have two leaves unfolded, trailing should be carried out. After the stolon elongates, it can be directed towards the surrounding of the mother plant. Cut off the stems connecting the stolon seedlings with the mother plant, which helps promote fruiting and fruit enlargement.

4. Applying Thin Fertilizer

According to the growth of strawberry seedlings, apply compound fertilizer, with more phosphorus and potassium elements and less nitrogen. Usually, applying thin nitrogen-phosphorus-potassium compound fertilizer every 20-30 days is sufficient. The principle of fertilization is to apply thin fertilizer frequently.

5. Weed Control

In summer, weeds grow vigorously, which easily affects the growth of strawberry plants and reduces their drought resistance. It is best to manually weed at this time, being careful not to loosen the strawberry roots when weeding to avoid seedling death.

6. Pest and Disease Control

The main pests are cutworms, which can be controlled by irrigating the seedlings with 800-fold liquid Dimethoate or 1000-fold liquid Dichlorvos. The main diseases include anthracnose and leaf spot disease. Spray treatment should be carried out at the early stage of the disease, and options for fungicides include Mancozeb, Pyrazole Ether Esters, Fenhexamid, and Myclobutanil.

Conclusion

In summary, it is essential to strengthen management during the high-temperature summer season, focusing on improving the drought resistance and disease resistance of strawberry seedlings, ensuring proper water and fertilizer management, and effectively controlling weeds to guarantee the vigorous growth of strawberry seedlings.
