Why are raised garden beds important?
It is essential to know why these beds are necessary for certain crops and how gardeners can benefit from them. Installing raised garden beds has both advantages and disadvantages. These can be helpful for gardeners suffering from back strain so they do not need to bend over when planting. Weeding is also handy for gardeners as they can simply sit at the sturdy edges of the garden beds. GrowVeg shares how you can use raised garden beds for better gardening. Read on!
What are the disadvantages of a raised garden bed?
Beds that are made of wood or other materials need to be filled with potting soil and compost. These are more expensive than the traditional vegetable garden. If you live in a dry climate, increased drainage is required for raised beds as they need more watering. Having a long-term irrigation system can make things easier.
Why do you need a raised garden box?
It keeps the weeds from the pathways, prevents hard soil formation, provides better drainage and drives away pests. This blog gives the basics of what to do when installing raised garden beds for your favorite crops.
Can you walk on a raised bed?
When beds and paths are clearly separated, walking on the soil can be avoided. As the soil squashes down, the essential air pockets can be removed. This makes it difficult for the plants’ roots to grow. Raised bed gardening provides a clear physical distinction between the growing area and the paths. You can access your garden without stepping on your plants.
