Boxwood Decline: Soil Quality, Not Iron Deficiency

Two boxwoods planted last year flank a garage. One thrives; the other shows overall bronzing, poor soil, and no mulch. The owner's uncle diagnosed iron deficiency and suggested ferric/ferrous oxide, unavailable locally.

Expert Assessment

The bronzing pattern doesn't match iron chlorosis (which shows green veins with yellow margins). The struggling plant is severely stressed—poor soil, dry conditions, no mulch. It is unlikely to catch up to its counterpart.

Recommendations

1. Replace the plant and amend the planting hole with landscape mix or topsoil.
2. Apply mulch to conserve moisture.
3. Use a root stimulator at planting.
4. If attempting to save the original, move it to a pot for intensive care.

For iron needs, Ironite is widely available at garden centers.
