Fixing a Non-Flowering Variegated Dogwood

Cause

Excess nitrogen from lawn fertilizer promotes foliage over flowers. Variegated dogwood in Michigan bloomed once in 7–8 years due to high-nitrogen runoff.

Solution

• Use acid-based, low-nitrogen fertilizer (e.g., Camellia/Rhododendron food or 0-10-10) after bloom.
• Apply 1 cup per inch of trunk diameter under canopy, water in.
• Avoid lawn fertilizer under tree.

Key Takeaway

Switch to phosphorus-rich, low-nitrogen fertilizer to stimulate flower bud formation. Keep lawn treatments away from root zone.
