Spring has rolled around, and it is time to enjoy some outdoor activities in the yard. The season initiates a whole lot of changes in plants as a new life starts to burst all around. Trees, in particular, are no exception. Unfortunately, not all changes are for the better, as tree surveys often reveal some trouble with the plants around springtime. Diseases and insects become active in that season, and it is up to you to stay vigilant. Being proactive and not allowing the issues to develop is a key strategy in ensuring the health of forests on your property. Here are few things to be on the lookout for:
Browning of tree leaves – while it is true that spring is the season of green, some trees exhibit a different color of leaves: brown. This is something you will find highly surpriving, but it is a symptom of trouble you can not overlook. After all, the contrast is rather striking. When you see the leaves browning at the veins during the budding period, you should assume it is a fungal disease. Anthracnose is the most likely type, as it is one to thrive in wet, crisp spring weather. To save the tree, you may have to resort to specialized treatment. It is at times like these that you need professional arboricultural consultants on your side.
You find a sticky substance on leaves – hungry aphids find sap specifically appetizing, as it contains plenty of carbohydrates. Once they have set their sights on a tree, they leave a sticky residual, also referred to as honeydew. This substance curls the leaves and joins mold fungi. With multiple different types of aphids out there, you have to select a treatment option in accordance. Consult with experts on what solutions you can use to deal with the aphid problem.
Scaly insects – apart from aphids, you also need to protect trees from scale insects. These are another common spring tree problem that needs to be addressed before it gets out of control. Scaly insects are similar to aphids in that they leave an identical mark, but they are far more destructive, albeit smaller. You can find them in clumps, forming spots of colors on the leaves, bark and needles. Applying the appropriate insecticide is critical for removing this problem.
Chewed and falling leaves – if you notice a tree's leaves are missing large parts of them and are falling prematurely in spring, it is most likely a case of caterpillars. Among the most common victims of these insects are maple, oak, elm, apple, hickory, beech and ash trees. If you already see such damage on your trees, you probably have to apply some insecticide. In the autumn you should focus on caterpillar prevention by using insecticidal tree band.
These are 4 of the most common spring tree problems that you need to be careful with. Detect them early enough, and you will better be able to control them. Otherwise, a tree survey will reveal trouble the next time it is done.
