Planting a Shade-Tolerant Barrier for Dogs in a Narrow, Sunless Alley

A Boise, Idaho mobile home resident wants to block a 4-foot gap between trailers with a hedge for two poodles. Conditions: no sunlight, moist soil, low maintenance, flowering preferred. Previous expert ruled out lilac (needs full sun).

Expert Assessment

• Lilac: impossible (requires full sun to bloom).
• Most deciduous shrubs need sun to flower.
• Space is small; climate (zone unknown) limits choices.
• Upright yew possible but needs periodic pruning.
• Rhododendrons might work if hardy enough for your zone.

Bottom Line

This site is not conducive to good plant growth. Without knowing your exact USDA zone, specific recommendations are risky. Consider non-plant barriers (fencing, lattice) or accept that any planting will be experimental and high-maintenance.
