🍏🌳Keeping Our Trees Healthy – Systemic Apple Scab Injections 🍏🌳
Apple scab is one of the most common diseases that affects apple and crabapple trees. It shows up as dark, scabby spots on the leaves and fruit, and if left untreated, it can really weaken the tree over time.
One option many arborists recommend is systemic injections. Instead of spraying, the treatment is injected directly into the tree’s vascular system. This way, the tree itself distributes the protection throughout its leaves and fruit.
If your apple or crabapple trees struggle every year with scab, a systemic injection might be worth considering this season. Our team of Consulting Arborists are here to help!
