Regularly check the moisture of the soil to determine whether a plant needs watering. If the soil is relatively dry, then water it to maintain a slightly moist soil condition. Grape honeysuckle in gardens with ample rainfall does not need watering. Make sure water does not accumulate in the soil. In drier weather, water the plants appropriately.
During summer, increase the amount of water provided. In winter, reduce it. Wait until the soil turns a lighter color before watering. It is recommended to water grape honeysuckle once every 3-5 days after pruning leaves or cutting off flowers. This will help it develop new branches and bloom more impressively. It is best to water it in the morning or early evening. Rainwater or snow water is better for watering than tap water. Tap water contains fluoride or chloride, which can cause soil compaction and worsen soil permeability, affecting the breathing of the roots.
