The Benefits of Raised Bed Gardening
Reduce Back Strain: Raised-bed gardening can reduce back strain because you won’t have to bend over as far to reach the plants. With easier access and less pain potential, you're better able to enjoy the labour involved in planting, tending, and harvesting vegetables. Build your raised beds so they're at least 12 inches tall. If the walls are slightly below waist level, you can sit on edges to work the soil and harvest your bounty without having to bend over at all.
Grow Longer: The soil in raised beds typically warms earlier in spring than the surrounding earth. It also tends to dry faster, so you can get cool-season crops planted sooner, extending the growing season and your vegetable crop choices.
Keep Clean: Spread mulch or pea gravel over the paths between your raised beds and your feet will stay clean, no matter how wet the weather. Because you won't walk on the beds, you'll be able to work in your garden without worrying about compacting the soil.
Overcome Bad Soil: Raised-bed gardening is the answer if you have sandy or clay soil. Instead of struggling with poor topsoil, all you need to do is fill your raised beds with high-quality garden soil and start gardening. Nutrient-rich soil means fewer struggles for plants and less frustration for the gardener. To keep the soil healthy, continue to top up your garden with compost or garden soil.
Reduce Weeds: Once your beds are filled with rich soil, cover the surface with and inch or two inches of mulch. This reduces weed competition and preserves soil moisture.
Stop Grass from Invading: Lawn grasses, which have spreading root systems, often infiltrate a standard garden and become a serious weed. But when you practice raised-bed gardening, nearby grasses won't be able to grow into your vegetable crop.
Stop Pests: Raised garden beds will put a stop to pesty critters such as moles and rabbits.
Never Till Again: Raised beds provide a healthier environment for beneficial microorganisms and earthworms because there's no foot traffic to compact the soil.
