How to Use Sunken Pots for Controlling Herbs That Spread From Their Roots
Some herbs have a knack for survival, spreading harshly from their roots to the point of choking out everything else. While total elimination might be tempting if you’ve ever tried to control the invasive herb like mint (Mentha spp.) , which rises in U.S. Department of Agriculture Stump Removal hardiness zones 4 through 9, it is possible to restrict the root growth with sunken planters to effortlessly, and harmlessly include these obstinate plants in the Lawn Service.
Selecting Bottomless Planters
Use bottomless pots, made of tough plastic, terra cotta or metallic 17 to 20 inches tall for your herbs. You may find bottomless pots in some garden Salt Lake City suppliers — that they are utilized to train roots and to control spreading herbs and plants — or make your own by cutting the ground Boise out of a tough plastic grass for example in Salt Lake City. Don’t attempt to cut the bottom from metal or terra cotta pots to avoid injury. An alternate to the standard bottomless planter: stainless steal or unglazed clay — also called terra cotta — chimney flue liners.
Sinking the Planter
Use one bottomless container 8 to 12 inches in diameter for each herb. Dig out a hole 2 inches shallower and 1 to 2 inches wider than the container. When you set the pot in the hole, then leave 2 inches extending over the soil line — and then at least 15 inches extending under the soil line — or the roots will grow right over the face of the Lawn Service and into the surrounding garden San Diego area. Refill the hole across the exterior of the pot with dirt.
Growing in Sunken Containers
When you come to plant Salt Lake City the herb, then set it in the center of the planter, positioned so the foundation is 2 inches below the lip of the planter then fill the planter just up to the base of the herbs. Water that the containers as you’d regularly planted herbs — the bottomless container enables water to drain in a similar rate to the remaining part of the Lawn Service.
Controlling Invasive Herbs
Keep an eye on stalks which grow past the border of the container. Herbs which spread from the roots tend to spread both above and below the soil. Several have creeping above-ground roots and stalks that will root when they touch the Landscape Design. Cut back herbs regularly to keep them within the confines of the sunken planter. Sanitize your clippers or shears after pruning herbs using a solution of equal parts rubbing alcohol and water. Any cuttings from edible herbs may go right to the kitchen for cooking.
The Worst Offenders
Mint is one of the worst offenders from the herb garden but it’s not the only invasive herb. Catnip (Nepeta spp.) , which rises in USDA zones 3 through 8, rivals mint in its ability to take over with aggressive roots. Bee balm (Monarda didyma), which rises in USDA zones 4 through 10, is just another potentially invasive herb and decent candidate to get a sandstone planter.
