Taking care of ornamental evergreen trees
Tips on taking care of ornamental evergreen trees for your landscape investmentEvergreens bring beauty and energy to any landscape. These durable trees are easy to love and relatively easy to care for. However, they do require come special maintenance to thrive long term.
Taking care of ornamental evergreen trees is a wonderful skill to have. Yes, you can always call a landscaper, but donít let pruning intimidate you. Once you learn the basics youíll understand how to properly prune, when do to it and why it must be done.
Your evergreens will need to be looked at and pruned every year. Before reaching for the tools, examine them for areas that look overgrown or weak. This will help you assess how much pruning will be necessary Ė whether youíll need to revive the treesí health or simply maintain bounds and allow them to grow.
Pruning tools must be cared for. Keep them sharp and lubricated to prevent rust. Invest in the best quality you can afford. Hand shears are useful for getting a close cut when the evergreens are young. Pole pruners extend your reach, but should never be used near utility lines. Pruning saws have wider teeth than standard saws to prevent tree sap from gumming between the blade.
You probably already know pruning is essential for trees and hedges. Specifically it allows you to control plant size so it doesnít overcrowd other trees and growth. Eliminating dead and weak branches promotes survival of stronger branches and new growth.
If you live in a windy area, thinning the crown allows wind to get through the tree. This reduces the risk of either branches falling or the whole thing coming down. This also prevents property damage and interference with power lines.
Removing brown needles and branches improves the appearance and makes you whole yard look better cared for. Cutting off dead and diseased braches also eliminates the chance of sickness spreading through the whole tree.
When to do it
Taking care of ornamental evergreen trees successfully means knowing the best time to do it. Most evergreens can be cared for any time of year as long as the wood isnít frozen, but ideally maintenance is timed around the growing habits of the tree. As trimming stimulates new growth, itís best to do so when the weather is conducive for new growth to thrive.
Late spring is the perfect time to prune evergreens. This catches them just as new branches elongate but before they stiffen.
There are a few different methods, depending on the needs of the tree. With evergreen shrubs and trees, thinning is often the best way.
Thinning completely removes a select branch back to the trunk. Be careful not to cut into the branch collar or too close to the trunk or you could leave it vulnerable to infection. Avoid cutting old wood as only the green portion of needle branches produce new growth. In general, heavy thinning will only need to be done every few years
You can thicken new growth on pines, spruce, firs and other coniferous varieties by pinching about 2 inches of new growth in spring. Donít use shears for this as the needles around the edge of the cut will brown.
While some believe dressing a wound with tree paint is good for the tree, horticulturalists disagree. This may actually harbor disease and slow healing. When appearance is a factor, use latex paint. If the evergreenís health is your only consideration, donít dress or paint a cut.
- Always survey the area and be aware of power lines.
- Call the power company if an electric line is touching your tree.
- Call in a professional if the size of the tree is too big for you.
- Keep your fingers clear from the clippers and away from your eyes until washing them.
