Just in time for spring: Raised beds for gardening

With winter behind us, we gardeners look forward to planting in spring, deciding on preferred vegetables and flowers and where to plant them for the best possible results.

We purchase from garden centers wisely and plant carefully, only to discover our plants are not thriving as we had hoped. If the problem is our soil and we have not had it tested at the OSU Extension, the soil might lack nutrients, and our gardens will struggle to produce a sizable fall crop. In such cases, a raised bed could offer the ideal solution.

There are many benefits to raised beds, particularly for individuals with decreased mobility, as they eliminate the need to kneel, bend down or perform tasks like rototilling. These beds, typically ranging from one to three feet in height, make planting, weeding and watering much easier on the body.

Soil conditions are improved since you avoid walking through raised beds, compacting the soil. Pest control also becomes easier, especially if the bed is lined inside with poultry wire, preventing moles and other burrowing animals from gaining access.

Overhead frames can be added to protect plants from cold nights or frost and can be used as protection for early seedlings.

Soaker hoses between plants offer slow irrigation, protecting the leaves from dampness and avoiding fungus or bacterial infections. With raised beds, higher vegetable yields are possible because of plants closer together, but not crowded, which avoids weeds.

However, raised beds dry out faster than ground soil and the initial cost of materials and construction can be discouraging.

Deterioration over time does require maintenance. Soil of a high organic matter needs to be added before each growing season. A compost bin is ideal for building rich soil and using mulch will retain moisture and prevent weeds from invading.

According to Penn State, rot-resistant wood such as cedar, redwood, oak and treated wood, although more expensive, is more durable. Boards from recycled plastic are not recommended as they tend to bow and lose their shape over time.

Pressure treated wood or railroad ties should be avoided as they contain chemicals that are toxic to plants.

Penn State suggests 3-inch galvanized screws are best for the support of the frame and installing stakes halfway through the bed prevents the wood from bowing from the pressure of the weight of the soil.

At the end of the growing season, if there was no infestation of insects or bacterial issues, the plants can be dug back into the soil to add organic matter.

Adding these nutrients to the soil will improve and enhance it in preparation for next years crops.

Gardeners love growing their own vegetables and flowers, taking pride in a successful crop and sharing with neighbors. Perhaps one or more raised beds are the solution for you.
