Revitalizing Large Potted Ficus and Schefflera Without Repotting

Nine-foot potted trees are too heavy to repot, but salt buildup demands action. Try an in-place soil flush: calculate the pot volume, multiply by eight, and slowly apply that amount of water over seven days. Remove leachate from saucers daily with a turkey baster or wet vacuum.

Alternatively, use a shop-vac hose to suction out the top 6–8 inches of old soil and replace it with fresh mix. Both methods reduce soluble salts and refresh the root zone without moving the giants.
