Pines – big and small – were the subject of a recent blog, and they are beautiful trees that bring a unique look to any garden, with so many to choose from. Pine trees are usually trouble-free, but, like all plants, they can be attacked by insects from time to time. Often these attacks are unsightly, but not fatal, unless the tree is very small, but they can weaken it, leaving a tree more susceptible to disease attacks, or environmental problems. Some are more serious, and these have become significant problems in some parts of the country. An idea of what a pest is, and how serious (or not) it might be, is useful knowledge for every gardener, so let’s look at some of the insect problems you might see on your pine trees.
