It’s a Wrap!
We’ve all heard the saying, “an ounce of prevention is worth a pound of cure.” This tried and true statement definitely applies when it comes to newly planted, young trees. Tree Wrap is that “ounce of prevention” that helps protect your young, thin-barked trees during their first couple of winters.
Tree wrap prevents Sunscald that occurs during our Iowa winters. Thin barked trees like Maples, Locusts, Crabapples, Oaks, Willows, Aspen and many others are especially susceptible to Sunscald. Sunscald happens when the sun shines on the tree’s trunk during the day, heating it up, and then temperatures drop drastically at night. Sunscald typically happens on the south or southwest side of the trunk. It causes large splits in the bark and makes your tree susceptible to disease, pests, and fungi. When splits occur in the trunk, it sometimes requires a “pound of cure” to get rid of these diseases, pests, and fungi.
When you wrap the trunk, you insulate your tree and protect it from the drastic temperature changes of Iowa winters. Tree wrap should be applied in the fall before it freezes and should be removed in the spring. As your tree matures, the bark thickens and Sunscald is no longer a problem. Wrapping your young tree the first 2-3 years is usually sufficient.
Tree wrap can be found at Farm and Fleet stores as well as big box stores like Menard’s. It’s usually less than $10 for a roll that covers several trees.
When applying tree wrap, start at the ground and wrap upwards, overlapping about 30% of the wrap. You may use tape to secure the tree wrap to itself but don’t tape the tree wrap directly to the tree.
