Will Shrubs Recover From Underwatering?

Wilting

• Drought stressed plants will wilt. At this point, the plant will revive quickly. Use a soaker hose to create a perimeter around the shrubs that extends 1 to 2 feet out from the drip line of the shrub. Soak the soil to a depth of 8 inches.

Leaf Drop

• As the feeder roots below the soil surface continue to dry out, leaves turn brown and drop. Dry, crusted soil repels water. At this point, the shrub is in danger. Remove any turf that surrounds the plant and soak the soil to a depth of 12 inches. Water in the early morning or evening to reduce evaporative water loss.

Long Term Effects

• Long term under watering affects the plant's overall health. New growth is stunted or deformed and the plant becomes susceptible to blights, cankers and rots.

Prevention

• Mulch the planting area around your shrubs and add organic matter to the soil to retain moisture. Choose drought-tolerant native plants to reduce the need for supplemental watering.
