Tree Diseases in Louisiana: What You Need to Know
Louisiana's warm, humid climate is perfect for growing trees—and perfect for growing diseases. Knowing what to look for can save your trees and your wallet.
Oak Wilt: The #1 Threat to Live Oaks
Oak wilt is a fungal disease that clogs the tree's water-conducting vessels. Symptoms include leaves turning brown from the tips inward, rapid canopy thinning, and tree death from the top down. Prevention includes never pruning oaks during growing season, avoiding wounding, not moving firewood, and sterilizing tools.
Root Rot: The Silent Killer
Root rot is fungal decay usually caused by poor drainage. Symptoms include yellowing leaves, canopy thinning, soft wood at the base, and mushroom growth. Prevent by ensuring proper drainage, avoiding overwatering, and removing standing water.
