Outdoor Raised Beds With Trees
With a bit of planning, landscape and fruit trees can thrive in raised beds. The most basic raised beds with trees is the ground bed. Ground raised beds consist of sloped, 6- to 8-inch mounds of soil mixed with compost, peat moss or manure. Ground beds should measure between 2 1/2 and 5 feet wide. Surround the ground beds with access areas at least 24 inches wide. Ground beds are appropriate for smaller tree species. Larger trees may require more space than raised ground beds can afford. Surrounding structures made from wood, plastic, rock or brick surround supported raised beds. Supported raised beds can be larger than 5 feet wide. The University of Minnesota recommends using untreated, rot-resistant wood such as cedar to construct a support structure. Once boards are connected with deck screws, fill in the bed with amended soil.
Supported raised beds can accommodate larger tree species as no sloping is necessary at the bed’s edge. Raised beds can help eliminate damage from wet soil. When planting landscaping trees in raised bed, planting depth is the most important consideration. To plant in a 10-inch-high raised bed, dig a hole the same depth and two to three times as wide as the tree’s root ball. Raised bed planting offers a solution to this problem, as raised beds dry out faster and offer better drainage. Beds should be at least 6 to 8 feet wide and 8 to 10 inches high.
