Minnesota is the land of 10,000 lakes, but it is also the land of 10,000 trees too. Trees are good for the environment and they make the landscape much more beautiful, but that does not all happen naturally. Tree pruning may be necessary at times to keep the trees healthy and looking their best. In addition to those reasons, there are many others that may prompt you to need the services of a tree trimming company for help with your landscaping.
One of the main reasons that it needs to be occasionally trimmed is for their health. It sounds like it should be the opposite, but pruning actually helps them to grow better. There may also be occasions where a branch or limb becomes infected. If this is the case, it is essential to remove the limbs as soon as possible. This needs to be done in order to contain the damage and to keep the other nearby trees from also becoming infected. Hopefully, if the infected limb is removed quickly, the rest of the tree can be saved. Keeping it trimmed when you discover dead branches can help to reduce the likelihood of an infection or decay.
Another reason that you may need to call a professional is to control the type of growth it has or to protect the other things around it, for example your house or the neighbor's house. It is not very safe to have trees that grow toward the power lines. It would be too easy for it to fall during a bad storm and it could take the power lines with it. Not only would that cause a lot of people to lose their power, it could also result in live power lines being on the ground. You may also want to keep the branches trimmed so that they do not get too close to your house. The limbs that brush the side of the house in the wind can make it really hard to sleep. You can also remove the overgrown branches in order to keep their leaves, etc. from falling on a neighbor's property.
For the most part, they can be trimmed whenever you want it to be done. But, there are a few specific species that should only be trimmed at certain times of the year. However, as discussed above, if you see that there are dead branches on your tree or it looks like there could be an infection of some type, you should have them removed right away to prevent further problems.
You have to be careful when pruning branches from flowering types because of the buds. If you trim off the buds, you are not likely to get the blossoms during the next year. Typically, it is considered safe to have these trees pruned three weeks after they stop blossoming. You also have to be careful if you have dogwood or oak trees. If you trim these types of trees at the wrong time of year, it can leave them a lot susceptible to certain disease carrying insects which can harm the tree.
