Spanish Moss on Dogwoods: Chemical and Cultural Control

Chemical Control

Copper-based products (same as for pecan): TC Tribasic Copper Sulphate, Blue Shield, Basic Copper 53, Micro Flo Copper 3 FL. Apply at ball moss rate.

• Timing: Before bud break or mid-summer (avoid tender spring growth).
• Coverage: Thorough spray to runoff.

Non-Chemical Options

• Hand removal: Pole or ladder for low growth; cherry-picker for high. Labor-intensive.
• Baking soda (off-label): 40 lbs/100 gal water—effective on ball moss, not registered for Spanish moss.

Ecological Perspective

Spanish moss is an epiphyte, not a parasite. It provides bird nesting material and insect habitat. Only treat if infestation is so dense it blocks light and reduces blooms/foliage—as you describe. Combine selective hand removal of heavy festoons with pruning of shaded, suppressed branches.
