Transplant Shock in a Large Mayday Tree

Why Daily Watering Is Harmful

A 20-foot tree moved in summer with daily watering is likely suffering from transplant shock and overwatering. Large trees need a massive root ball (9–12 inches width per inch trunk diameter; 6 inches depth per inch) and a strict watering regime.

Correct Care Now

Stop daily watering.
Water deeply: 1 inch every 3 days for a month, then weekly (use a pan to measure).
Mulch 3 inches deep, keep off trunk.
Do not fertilize for a year.

Future Moves

Transplant in early spring or fall. Prepare the new hole first. Protect root ball with burlap. Water consistently but not excessively.
