☀️🌳HEAT STRESS IN TREES!🌳☀️
Hot, dry weather puts trees under significant stress. Heat can lead to weakened branches, leaf scorch, dieback, and even unexpected limb failure. Common signs include brown or scorched leaves, dying branches, cracked soil around the base, and an increased risk of disease, pests, or even branch failure. Many of these problems aren't obvious until the damage is already well underway.
In summer, the biggest tree hazards are Summer Branch Drop (SBD), heat stress, and poisonous foliage. SBD involves seemingly healthy, mature trees (like oaks, beeches, and ash) suddenly shedding heavy branches on completely calm, dry days.
Specific summer tree dangers to watch for include:
-Summer Branch Drop: Common in mature oak, ash, and beech trees. Prolonged dry spells dry out the wood, making branches heavy and brittle. They can snap and drop without warning, so avoid parking or setting up picnic spots directly under large, overhanging limbs during hot weather.
-Heat and Drought Stress: Look out for wilting leaves, yellowing/brown edges (leaf scorch), and premature leaf drop. A highly stressed tree becomes more susceptible to pests and diseases, and can develop brittle deadwood high up in its canopy.
-Toxic Sap and Berries: While less common in the UK, trees like the Yew (Taxus baccata) contain toxic foliage and seeds.
-Fungal Inroards: Summer heat often causes brackets or fungi to appear around the trunk and base of the tree, signaling internal decay that weakens the structural integrity.
Early intervention can help protect your trees and avoid more costly problems in the future. A professional tree survey can identify early signs of stress before they become costly or dangerous.
