Watering Forsythia

Forsythia is a flowering bush with moderate water needs. Newly planted Forsythia shrubs need regular waterings, while established plants develop drought tolerance and can handle less frequent watering. Ensuring your Forsythia has a good water supply allows the plant to create a strong root system and deliver dependable sunny yellow blooms each spring.

How To Tell If Forsythia Needs Watered

Forsythia is a deciduous bush with woody branches extending from the plant's center. The flowers may wilt and drop, or the leaves may curl and droop when the plant needs water. Dry or cracked soil is also a sign that the plant is dry.

How Often To Water Forsythia

A newly planted Forsythia appreciates moist conditions. Give young plants about 2 inches of water per week, including natural precipitation. Consistent water helps the plant develop a robust root system.

Established Forsythia plants rely on their deep root system and rainwater to support the plant. After these plants have settled in, they develop drought tolerance and do not need frequent watering. While established plants have low water needs, give the plant a drink during a dry spell to support continued growth. Be careful not to overwater this shrub because too much water or poor drainage can lead to root rot. 

Potted Forsythia has higher water needs than plants grown in the ground. Water container-grown Forsythia when the top few inches of potting mix feel dry.

Best Time To Water Forsythia

Water newly planted or potted Forsythia in the morning, so the roots have time to absorb the water before the afternoon heat kicks in. Dry plants can be watered at any time to prevent further dehydration. Avoid watering in winter when the shrub is dormant. Pots without access to moisture during the winter should be watered sparingly to prevent the soil from completely drying out.

How to Water Forsythia

Step 1 - Water newly planted Forsythia weekly.

Give young plants about 2 inches of water each week, preferably over 1-2 deep watering sessions.

Step 2 - Check the Forsythia for signs of water stress or dehydration.

Wilted or drooping flowers or foliage and dry, cracked soil are signs the plant needs water.

Step 3 - Water the ground around the plant.

Saturate the soil around the base of the Forsythia bush, and avoid wetting the foliage.

Forsythia Watering Tips

  • New Forsythia plants need about 2 inches of water weekly
  • Drench the ground around the base of the plant when watering
  • Established Forsythia shrubs are drought tolerant, but appreciate water during a dry period
