Some people say that with all the pollution in the air today, it is hard to grow vegetables that are healthy. This may be true but for the pollution in the atmosphere to affect vegetables, the pollution must have contaminated the soil and unfortunately that is the case in many areas. The answer to this problem though is easy; use raised garden beds.
Raised garden beds are boxed in areas where you can control what soil is placed in the box, ensuring that it is contaminant free for the healthy growth of your vegetables. The bed is raised to a height of between 6 and 36 inches and then filled with a soil that you have bought. Once you have nutrients to that soil, you can plant your vegetables and whilst they are young and vulnerable to harmful contamination, will be safe in their enclosed area. As a raised garden bed has no bottom, as the plants get bigger and stronger, not so prone to contamination damage, they can spread their roots into the ground soil where they will benefit from the natural nutrients that exist in it. It is worth noting though that the soil in these raised beds tends to dry up more rapidly than ground soil and so may need more watering especially in the hotter weather.
Apart from varying in height, garden beds also vary in size and so you can either make one or buy one to a size that suits your needs. As far as the height of these beds goes, the most commonly used height is 11 inches but the higher ones are available for people who may prefer, perhaps because they want to sit on the side of the box whilst carrying out tasks such as weeding and other necessary maintenance. Obviously the lower the height, the faster the roots will reach the ground soil and so if you are concerned about that, that would be another reason to get a higher box.
Although many people do make their own raised garden beds in which case they will usually use cedar as that is one of the longer lasting varieties, many others opt to buy their garden beds in which case they will have a choice of either wood or plastic. As wood, even cedar is eventually going to be prone to rot or become mouldy, plastic is a popular choice and the plastic recycled garden beds 2015 come in many varieties and so you will surely find one that will ideally suit your needs.
Obviously possible potentially contaminated soil in your area is a good reason to use raised garden beds for growing your vegetables, many people even with good soil, opt to use raised garden beds as they can add a touch of character to their garden, plus of course give them a controlled quality of soil in which to grow their plants. Even if the soil in your area is good today, with the ever increasing number of contaminants in the atmosphere, you do not know how long your soil may remain healthy and unpolluted.
