About this episode
In today’s newsletter podcast (above): America’s Favorite Retired College Horticulture Professor, Debbie Flower, discusses the pros and cons of bypass and anvil pruners; and the best tool for sharpening pruners. This time of year, stroll down the tool aisle of any garden center and you'll find a vast array of cutting instruments, all designed with the backyard gardener in mind. Blade heads of short-handled pruners and long-handled loppers usually come in two different styles: bypass and anvil. Bypass loppers or pruners have a stainless steel curved blade that uses a scissors action to pass next to, not on top of, the lower surface, sometimes called the hook, designed to catch and hold the branch while the cutting blade comes down. Bypass pruners offer a cleaner cut, as the blade slices all the way through the stem. The cutting blade of anvil-style pruners comes down onto the center of a soft metal or hard plastic lower surface, called the anvil or table. Anvil pruners tend to crush the soft tissue of the stem, stopping the flow of nutrients, prolonging the healing time for the cut surface. Despite the bypass pruner's benefits, garden centers still offer a nearly equal number of anvil-style pruners and loppers, a never-ending source of confusion for the gardener hunting for cutting tools. We asked local garden experts their pruning preference: bypass or anvil? The late Sacramento County Farm Advisor, Chuck Ingels, preferred bypass pruners. "I never use anvil pruners because you often can't cut close enough to the branch collar without leaving somewhat of a stub," said Ingels. "When they begin to wear, they often don't cut all the way through. Also, they crush the bark, which bypass pruners can do also, but you can turn the shears so the blade is closer to the collar and make a clean cut." "I don't use and usually do not recommend anvil pruners," says Luanne Leineke, formerly the Community Shade Coordinator for the Sacramento Tree Foundation . "I tend to see too many wounded branches, particularly when the bark is soft. I suggest using bypass pruners for up to three quarters of an inch-thick branches, loppers for up to one inch thickness and a hand saw for anything larger." Pete Strasser is a former plant pathologist with a former Sacramento nursery, Capital Nursery. Pete has only one use for anvil pruners. "Anvils are for deadheading annuals, and that's about it." Loren Oki, Landscape Horticulture Specialist with UC Cooperative Extension in Davis , also has limited use for anvils: "I was taught that bypass pruners were used on live material, whereas the anvil types were better for dead wood. The bypass type cuts cleaner through the softer material without causing much damage." Steve Zien, owner of the Citrus Heights-based organic landscape consulting business, Living Resources , leaves no doubt to his preference: "I would never use anvil pruners! Never ever, unless something needed to be pruned right then and there, and it was the only tool I had beside my teeth." Bottom line: Bypass pruners are much more versatile than anvil pruners. Every gardener should own a pair of bypass pruners. But a word of warning: don't force cut a branch with bypass pruners that were not meant to cut a larger branch. Using too much force to work the blade through the wood could damage the entire unit. If those bypass pruners are advertised as cutting through one-inch branches, don't exceed that limit. Move up to a larger cutting tool for those bigger branches, such as bypass loppers, a small branch saw (my favorite), a bow saw, or when you finally realize that "Life is too short to put up with a problem plant", a good quality chain saw.Perhaps have a pair of small bypass snippers for the cut flower garden. And larger anvil ratchet loppers for removing dead wood. Finally, whatever you purchase, buy quality. Look for pruning tools that have replaceable parts (blades, springs,etc) that can easily be disassembled for cleaning, sharpening, oiling, and maintenance.
