1. Observe soil moisture.
Before watering, feel the moisture of the soil by inserting your finger into the soil about 2-3 cm deep. If the soil feels dry, it needs to be watered. If the soil feels moist, it doesn't need to be watered. It's a simple yet effective way to help you tell if you need watering.
2. Avoid watering at noon.
At noon, the sun is strong and the temperature is high, and watering at this time can easily lead to an increase in water temperature and cause damage to the root system of seedlings. Therefore, it is best to water in the morning or late afternoon and avoid watering at noon.
3. Pay attention to the watering method.
When watering, try to avoid pouring water directly on the leaves of the seedlings to avoid causing leaf rot. Drip irrigation, sprinkler irrigation and other watering methods can be used to evenly sprinkle water on the soil surface.
Fourth, regular fertilization.
Spring is the peak season for seedlings to grow, and sufficient nutrient support is required. Fertilizer can be applied every 2-3 weeks to meet the growth needs of the seedlings.
Fifth, pay attention to the fertilization method.
Fertilizer should be evenly spread on the soil surface, and then gently ploughed the soil to bury the fertilizer in the soil. Avoid sprinkling fertilizer directly on the roots of seedlings to avoid burning the root system.
6. Prevention of pests and diseases.
Spring is the peak period for the occurrence of pests and diseases, which needs to be prevented in time. Pesticides can be sprayed regularly or added to the soil to prevent the occurrence of pests and diseases.
Pay attention to the safety of pesticide use.
When using pesticides, attention should be paid to safety to avoid pesticides causing harm to the human body and the environment. You can choose low-toxicity and high-efficiency pesticides and use them according to the instructions for use of pesticides.
Prune regularly. Spring is the best time to prune seedlings, which can remove dead branches, diseased leaves and overly dense branches, and promote the growth of seedlings and ventilation and light. Care should be taken to avoid over-pruning when pruning, so as not to affect the growth of seedlings.
Pay attention to the trimming time.
Pruning should be done in the morning or late afternoon and avoid at noon to avoid direct sunlight causing damage to the seedlings.
