Watering Mature Liquidambar (Sweetgum) in Clay Soil

Watering Rule

17-year-old liquidambars in clay only need water during dry spells. Clay holds moisture well.

How to Water

• Check soil 2" down—if dry, water.
• Apply 1 inch (pan test under sprinkler).
• Once weekly if no rain.

Key Point

Overwatering in clay causes root rot. Mature trees have extensive root systems; they're drought-resilient. Water only when soil confirms need.
