Ask any landscaper and they'll agree: pruning your plants is an essential part of healthy landscaping. Pruning does, however, require a degree of skill. STIHL is here to help. Part of our How-To Series, this article provides tips on how to properly identify plants and prune them to their fullest growing potential.
The first step in proper pruning is correctly classifying your plants. Not all varieties of plants (such as flowering shrubs) can be pruned at the same time of year, so it's important to know what time is best to prune the plants on your property. A good resource for plant identification is the National Institute of Food and Agriculture (http://www.csrees.usda.gov/Extension/). There, you can explore "Horticulture" and "Plant ID" tabs with links to photos. You can also consult with your local nursery.
Once you have identified your plants, it's time to make a plan. Most plants can be lightly pruned throughout the year. By "light," we mean don't remove more than 10 percent of the plant's live foliage. If your goal is to improve flowering, prune according to the plant's blooming cycle. For shrubs that flower in the spring, make your cuts in late spring and early summer; and for summer blooming shrubs, late winter, before the leaves arrive. Remove dying and diseased wood year-round.
We recommend STIHL hand shears for limbs up to three-quarters of an inch in diameter, depending on plant species and toughness. Two-handled lopping shears are well suited for branches up to one inch in diameter. For limbs with a greater than one-inch spread, we suggest a hand- or pole-pruning saw. Lastly, to clip or sculpt hedges and shrubs, opt for either manually operated or power-driven hedge shears. Note: Remember to wear the proper protective gear: goggles or glasses, gloves, and an approved hardhat to protect against falling debris.
After selecting the twig or branch you want to cut, prune it back to a lateral bud or larger branch using your pruners or lopping sheers. Your cut should be perpendicular to the growing direction. Remove the shoots around the base of the shrub before the new growth begins in early spring. Make sure your particular plant can withstand this base pruning. If a shrub is aged and large, eliminate one-third of the oldest growth each year. Use a pruning saw or lopping shears to cut back the branches to the base.
