Pyracantha is more drought resistant, and the demand for water supply is not very high. The time of watering depends on the soil condition. If the soil is dry, it needs to be watered. When the weather is dry, the leaves need to be sprayed with water frequently. Don't water it too much during flowering to make it bear fruit better. In rainy season, the water should be drained in time to avoid falling flowers. It can be watered every 2-3 days in spring and autumn, once a day in summer and once every 3-5 days in winter.
