Clean Cuts

Clean Cuts

Spring cleaning happens every year in my home and my landscape. I dust my photo frames, scrub the bathroom and polish the furniture. Then, I head outside to sweep the dead leaves off the porch and clear out my flower beds of winter's pesky bits of debris.

Through the years, I've realized a weekend of heavy-duty dusting, scrubbing, sweeping and shining refreshes my mind - and my home - before the warmer climate and growing season begin.

But why organize only one mass cleaning spree a year? I could use a fresh start before the cold winter months, too. In terms of tree care and maintenance, late fall and even early winter are perfect times to clean pruning tools and yard supplies - when they're not in use.

Although your plants are dormant, active plant diseases may linger on pruning blades until spring. While your trees and shrubs rest in winter, take the opportunity to sterilize and repair your pruning tools.

Although non-sanitized hand pruners, hand shearers and loppers do not necessarily spread pest problems from tree to tree, dirty tools can spread diseases. "Fungal diseases can attach to the blade on a pruning tool," says Greg Mazur, tech advisor for The Davey Tree Expert Company.

Fungi-infested tools can spread diseases to similar, unaffected plants while pruning, Mazur explains. Diseases that commonly spread from tree to tree via non-sanitized tools include fire blight on pear trees, oak wilt on oak trees and Dutch elm disease on elm trees.

To sterilize pruning tools, Mazur encourages homeowners to use a 10 percent bleach/90 percent water solution. "Make contact between the solution and the blade for about one minute, then rinse off the solution," he says, adding that other household cleaning supplies will not kill fungal spores as effectively as the bleach solution. "Apply oil to the cutting blade on a pruning tool to keep it from rusting," he adds.

Hand pruners, hand shearers and loppers are all common pruning tools that require proper, thorough cleaning. But even if you regularly clean your pruning tools (after each use is highly recommended), you can still use the winter months to work on repairing and preparing them for future use in spring.

"Sometimes people use a lopper to cut branches that are too large, which bends the blade," Mazur says. "So sometimes it's a good idea to sharpen blades and realign your tools in winter. Otherwise, your tools won't be able to cut as cleanly when you need them."

The same applies to lawn mowers. For several reasons, homeowners should occasionally check their lawn mower blades for dulling.  Mazur says sharper blades reduce the opportunity for diseases to invade turf by 20 percent: "Because the shredded ends of grass blades - which provide more opportunities for diseases to invade the turf - won't exist, sharper blades reduce the mower's fuel consumption by 20 percent."

So, just because the cold air and bone-chilling breezes are here to stay for a while, proper tree care practices don't have to end now. Spruce up your pruning tools while they're not in use and be grateful you did when you need them next year. Better yet, your trees will thank you for your efforts when their healthy, pruned structures blossom in spring.

  • Root in Moisture

    Planting trees is just half the battle.

    The diseases, pests and power equipment that emerge outdoors in spring, accompanying frequent sunlight, longer days and warmer temperatures, can wreak havoc on your trees if you don't put forth the effort to protect them.

    To keep your trees healthy throughout the growing season and beyond, you must practice routine maintenance and proper tree care. One way to help trees retain moisture, reduce weeds and keep power equipment at a safe distance is through mulch. In the coming weeks, you'll see piles of fresh mulch lined along neighborhood driveways. Soon, the coarse, fragrant matter will settle among flower and tree beds, enhancing the quality of landscapes' appearances.

  • Just a Trim, Please

    Put a pair of scissors in your hands, and whether you're cutting coupons or bangs, there's always the potential to oversnip. It's almost too easy to make a mistake as you clip, clip, clip away - removing a little more on this side and a bit more on that side.

    Just like with a bad haircut, there is nothing more noticeable than a poorly pruned plant - pieces sticking out in all directions, a butchered shrub, a tree that looks like the top has been sliced off. The good news is that just as the perfect haircut can frame the face and improve a person's appearance, the same can be said for a professional tree pruning job.

    Pruning is not only a science, but an art form. The science aspect of pruning involves understanding tree biology, recognizing plant flaws and skillfully eliminating or minimizing defects. The artistic aspect of pruning consists of removing dead wood while aesthetically shaping the tree.

  • Heat Wave

    Heat wave.

    The term usually makes many people think of the tropics or the desert.

    But extreme heat has hit many areas hard so far this summer. Record highs have been broken in some cities, while others have seen their hottest temperatures since the 1980s.

  • Forecast: Hot & Humid

    The air-conditioning is set on high. The fan is blowing in my face. And it feels so good, particularly since my dog and I were just panting within seconds of stepping out to a heavy wall of heat and humidity. His face tilts up to mine, happy for the nice, cool breeze. We face the facts together as I sip from a tall, cool glass of water and he laps up the same out of his bowl: Despite our yearning to enjoy the outdoors, it's hot. And it's hot in nearly every region of the country.

    There's simply no denying it: This summer's a scorcher. While it's difficult to find the motivation to open the door to the heat lingering in the air outside - let alone step out onto a dry, parched lawn - I brave the elements because I notice my trees need some TLC, too.

    It's difficult to imagine another day of 90-plus degree temperatures. So I can hardly imagine how my trees must feel as their roots cling to nothing but the dry soil, day after day.

  • Try a Little Tenderness

    When someone moves into a new home, they tend to have a smoother, more successful transition when they plan ahead and carefully move through each step. This includes thoughtfully packing boxes beforehand in an organized fashion, clearly labeling the boxes so movers put them in their proper rooms and then unpacking them so everything that is removed is unwrapped and put into its place to avoid rework.

    If this works for your most delicate China place settings and Lenox crystal, you can see why it would make all the difference when moving something as large, yet just as delicate, as a tree.

    When it's a big, valuable tree that provides numerous benefits to your landscape and your family, a "move" is much more than just picking it up and placing it in its new location. To preserve the numerous benefits trees provide to a community and its residents, which The National Tree Benefits Calculator can help determine, one must plan carefully - before, during and after the big move - to ensure survival.
