What to Do About Seedling Death After Transplanting Strawberries? The Latest Control Methods
Strawberries are generally grown by raising seedlings and then transplanting them; direct sowing is rare because the seeds are too small and unsuitable for direct sowing, and direct sowing produces uneven emergence. Replanting to fill gaps cannot keep up with the growth period. Seedling death often occurs during transplanting, and can even be severe. So what are the causes, and how should you transplant to avoid seedling death? What should you pay attention to? Let's take a look together at the causes of seedling death and the solutions.
1. Seedlings carrying pathogens
It is possible that they were already infected with fungi or bacteria during seedling raising, but had not yet developed the disease; then when they were transplanted and growth had not yet recovered, the disease broke out. During the seedling stage, warmth and moisture must be maintained, and some pathogens easily cause infection, such as anthracnose, which develops from the inside outward. You can use 25% Amistar for treatment. Or pyraclostrobin; a variety of chemicals can be chosen.
2. Soil carrying pathogens
If the soil has been continuously cropped for many years, or continuously cropped with the same type of crop, the same disease-susceptible crop. Various pathogens already exist in the soil itself; some can directly invade from the root system, and some can infect through wounds. Generally, before planting, sun the ground, and after turning the soil, sun the ground again. Spray carbendazim, and three days later you can transplant, which can reduce the possibility of infection. Continuous cropping of strawberries will inevitably lead to degeneration, so crop rotation is necessary.

Whether planted deep or shallow, the crown must not be buried. When planting, face the flowering position outward, which is helpful for picking. When planting, the soil should preferably reach the base of the stem, the crown area; do not let the roots be exposed. The root system should be completely covered; if the roots are not covered, they will dry out and die. Do not bury too deep either, or the stem will easily rot. If the crown is buried, it is planted too deep and will definitely rot. The seedlings will easily die.
4. Management and care
Use organic compound fertilizer as the base fertilizer; it must be piled up and fully fermented and decomposed, and used after high temperatures kill insect eggs and pathogens. Do not use poultry manure; the temperature is too high, it burns the seedlings, and they easily die. Planting should be done when the temperature has dropped somewhat. In some places August is still hot, so it is best to transplant when the actual temperature is around 25 degrees. Otherwise, with high temperatures and no shade, they will easily die. After transplanting, water once, then spray water morning and evening; once the seedlings have successfully recovered, you can water more.
Strawberry seedling death after transplanting is not only due to incorrect planting methods; in fact, management during the seedling stage is also very important. Early disinfection work and later care work must be done properly.
