Willows thrive in damp soil and will grow best in a naturally wet area, like a marsh or near a pond or some type of water. Young plants often need supplemental water to establish and grow an extensive root system. Once the plant has settled in, it will seldom need water, but it may need your help during an extended dry spell.
How To Tell If Willow Needs Water
The telltale sign that a Willow needs water is wilted or drooping foliage. In extreme dryness, the shrub will not bloom, and leaves will fall off the branches. A Willow in need of water will appear to be in distress and not look vibrant and healthy. During a drought, the ground surrounding the plant may appear dry and cracked.
How Often To Water Willow
Newly planted Willow shrubs need water when the top couple of inches of the ground are dry. Feel the soil to determine the dryness and need for water. Depending on the sunlight and climate, a young Willow may need water daily or every few days.
Established Willows need water weekly or when the top layer of soil is dry. These shrubs thrive in damp conditions, so regular watering may be necessary. Monitor the plants, especially during a dry spell, and water as needed. As much as Willows love water, standing water can be damaging. Do not water the plant if the soil is damp.
Potted Willow needs water when the top couple of inches of potting soil are dry. Container plants dry out quickly, so plan to water as often as daily.
Best Time To Water Willow
Mornings are generally a good time of day to water Willow shrubs. Early watering sessions allow the roots to soak up moisture before the intense afternoon sun hits. Watering later in the day when temps are higher can increase the rate of evaporation and limit the ability of the roots to absorb moisture.
How to Water Willow
Step 1 - Monitor the plant and the soil.
Check the plants and inspect the soil for signs of dryness.
Step 2 - Drench the ground at the base of the plant.
Saturate the ground around the root zone. Water the ground and stop applying water when drainage slows.
Step 3 - Spread mulch around the shrub.
Apply a thick layer of mulch to retain moisture and slow water from evaporating from the ground.
Willow Watering Tips
- Newly planted Willow shrubs need water when the top few inches of soil are dry.
- Established shrubs are drought tolerant but need water during an extended dry period.
- Water Willow shrubs until the root zone is saturated.
- Use organic mulch to retain moisture and slow evaporation.
