Boxwood Health: Root Zone Management for Long-Lived Shrubs

Boxwood decline usually stems from root zone issues: poor drainage, pH imbalance, or fertilizer burn. The 100-year-old specimens at Barnsley Gardens thrive because their roots are happy.

Planting Protocol for Success

1. Replace half the planting hole soil with ground pine bark
2. Mix thoroughly with native soil
3. Add 1 cup garden lime (boxwoods dislike acid soil)
4. Water weekly: 1-2 gallons per foot of plant height

Fertilization Wisdom

Boxwood roots are fine and fertilizer-sensitive. Old-timers use 1" cottonseed meal under fresh pine straw each spring—slow, gentle nutrition that mimics natural soil processes.
