Wintertime isn’t just tough on plumbing and roofing; it is also brutal on trees. Tree roots can freeze when soil temperatures drop below 15°F or the water within the soil surrounding the roots freezes and expands. So, what happens when tree roots freeze? What should you do in the event of root freezing?
In today’s blog post, Driscoll Tree Service explains what can happen if tree roots freeze. We also share tips that will help you protect trees from freezing temperatures. When you’re looking for a dependable tree service, trust the specialists at Driscoll Tree Service to provide reliable services.
Root Damage
A light freeze may not cause much harm to tree roots, but a severe freeze below 15°F is sure to damage the root cells themselves. Frozen water within and around the roots can cause cellular rupture and hinder the roots’ ability to function properly. The trees may exhibit wilting, discoloration of leaves, dieback of branches, delayed bud break, and even root rot. In severe cases, the root damage can be fatal. It’s best to consult with a trusted tree company if you notice any of these symptoms.
Disruption of Water and Nutrient Uptake
Another scenario you can expect when tree roots freeze is a disruption of water and nutrient uptake. Frozen roots are unable to absorb water and essential nutrients from the soil. Even though there may be water present in the soil, in its frozen state it is unusable to the tree. This effect is similar to the tree experiencing a drought. Trees deprived of the resources they need for survival become stressed, weakened, and increasingly vulnerable to disease, pests, and further environmental damage. If the freezing event is severe or prolonged, the tree's vascular system can be permanently damaged.
Increased Vulnerability
The disruption of water and nutrient uptake exposes trees to pest infestations, diseases, and further damage from extreme weather conditions. Pests and diseases often target weakened trees, taking advantage of their compromised defenses. This is why it’s important to take preventive measures to protect tree roots from freezing temperatures. If you need help, consult with a nearby tree company.
Water the Tree Properly
Once the ground thaws, deeply water the tree to rehydrate it. Avoid overwatering, as this can lead to root rot. Focus on slow, consistent watering to allow the roots to absorb moisture effectively.
Mulch Around the Tree
Apply a thick layer of mulch around the base of the tree. This insulates the soil, moderates temperature fluctuations, and retains moisture. Mulch helps protect the roots from further temperature extremes.
Prune Dead or Damaged Growth
Carefully prune any dead or damaged branches to remove stress from the tree and allow it to focus energy on root recovery.
Provide Shelter
If possible, shelter the tree from harsh winds and direct sunlight, especially during the recovery period. Temporary windbreaks or shade cloths can help reduce stress and prevent further damage. This is especially helpful for younger trees or trees that have had extensive root damage.
