A raised bed vegetable garden are usually built with wood, concrete blocks, rock or other materials which are then filled with earth. Depending on your requirements they can stand anywhere from six inchesto waist height above the land. Common motives for building a raised bed is for simpler accessibility for individuals who find the bending over movements, so familiar to conventional gardening, tricky or awkward to carry out.
It's important to consider your construction materials prudently since lumber, for instance, that has been treated can enable toxic chemicals to leak into the soil and which winds up in the vegetables themselves. It's better to use hard wood or rocks.
You need to take into account how level your garden is as well. A slanting area is more demanding to work on than a flat one and if it's really steep you might get soil erosion subsequent to heavy rains. One tactic to help cope with this is to position the beds across the slope.
In addition, if your garden is very breezy you might have to put up windbreaks. Ensure that they are porous so the air can pass through, otherwise they will fall down or produce turbulence and you'll have to begin again. They can be man made like a fence or an alive barrier such as a hedge. The latter tends to be more pleasing but will take time to grow and will entail effort to keep it healthy and appearing good.
The most common shape for a raised bed garden is a rectangle although now and then they're circular with a slice removed so the center can be reached more easily. These are called keyhole gardens and are especially good in regions where there's a shortage of water. In these circumstances a chimney type structure may be constructed in the middle and filled with grass and twigs. When this is filled with water it permits it to run more evenly into the earth, effectively reaching the roots of the vegetation sown in the raised bed.
Planting is ordinarily done in geometric patterns and is closer together than you normally find when gardening in rows directly into the ground. The closeness of the crops to each other can cause a microclimate which helps to preserve moisture and keeps the weeds down. Furthermore the soil doesn't get compressed, as there are no human boots walking on it, so the roots can grow without restraint. These dissimilarities from conventional planting regularly lead to more vegetables being produced.
