1. Organic soil
Watermelon roots have very high requirements on soil layer. Humus soil, sand and pine needle soil should be mixed and mixed evenly in a ratio of 1:1:1. Before planting, a little base fertilizer can be added to the soil layer. After that, the pot should be turned over every year to facilitate the growth and development of the roots.
2. Reasonable watering
Watermelons like to grow and develop in a humid environment. When watering, try to keep the soil layer moist as often as possible. In autumn and spring, they are watered every 2-3 days, every 1 day in summer, and every week in winter. In rainy days, water should be controlled.
3. Nutrient demand
Watermelon is a kind of fertilizer loving green plant. It is topdressing once every 30 days during its growth and development. It is mainly composed of water-soluble compound materials. Under the condition of good growth, it can be topdressing 1-2 times of manure and urine fertilizer to facilitate the growth and development of green plants. The fertilizer can be stopped at the flowering stage.
