Diagnosing Yellowing Evergreens in Sandy Soil

Newly planted evergreens turning yellow in sandy soil often signal one of three issues: spider mites, water management, or site mismatch.

Check for Spider Mites First

Hold white paper under foliage and tap sharply. Mites are tiny (1/4 the size of a period) but visible as moving specks. If present, treat with a miticide.

Watering: Thorough but Infrequent

Sandy soil drains fast. New plants need daily checks. Water deeply to wet the entire root ball, then allow the top few inches to dry before rewatering. Constant moisture causes root rot; drought causes desiccation.

Evaluate the Planting Site

Has sun/shade exposure changed? Is the plant suited to the location? Even correct care won't save a plant in the wrong spot.

If mites and watering aren't the issue, the problem is likely physiological—stress from transplant, site conditions, or weather extremes. Isolate the cause before treating.
