Planting Impatiens Under Trees: Beating Root Competition

Tree roots outcompete flowers for water and nutrients. Success requires soil preparation that gives impatiens a fighting chance.

Planting Protocol

1. Loosen entire planting area deeply
2. Incorporate generous compost or composted manure
3. Mix in time-release fertilizer (Osmocote or Proven Winners)
4. Plant impatiens

Watering for Deep Roots

Never hand-water. Use sprinkler or soaker hose for 1+ hours. Deep soaking encourages deep roots that withstand afternoon heat. Hand-watering creates shallow roots that wilt daily.

Light Conditions

Brief late-day sun (5:45-6:50 PM) in Zone 7 is acceptable for impatiens. They need 3+ hours direct sun to bloom well. Morning sun is ideal; this timing works.
