Big trees are under siege from a variety of threats. They need attention and care. Here are some tips on how to care for big, old trees:
Protect the bark from damage from yard equipment
Spread mulch around the base to insulate the soil
Avoid compacting the ground around a big tree
Keep branches free from hanging things
Water when dry to avoid stress when it’s hot
Also, big trees should be inspected by a certified arborist periodically. The arborist can spot trouble early, like diseases, rot, and heavy dead branches. He or she can also spot problems early and recommend pruning or other measures that can preserve the tree’s life.
