I live in Scarborough, Ontario. I would like to garden this year with raised beds. Kindly give me some contact addresses of people/ shops who sell raised beds or raised bed components cheaply. I visited some stores but they are very expensive. If I have no other option but to construct a raised bed from lumber, please advise how to construct one, the lumber that is okay for vegetables and other construction materials needed.
Raised garden beds are an excellent way to grow vegetables and flowering plants, for a number of reasons, including: the soil warms faster in spring, the beds are more accessible, the soil doesn’t become compacted by foot traffic, and they are easier to keep free of encroachment from grass or invasive plants. You’re right that they are expensive to buy, however, and I don’t know of any shops where they are cheap.
If you want wooden raised beds, cedar is probably the best option. It is rot-resistant and will last longer than most other kinds of lumber. Pressure-treated wood is not recommended for raised beds because of the possibility of chemicals leaching into the soil. Most experts suggest a bed no wider than 4 feet, so you can easily get to the middle of it from either side, and of 8 to 10 feet long. Here’s how to determine the size of beds built from lumber:
Here’s an example of how to build a raised bed:
Besides lumber there are many other building options, including wattle, logs, concrete blocks, even sandbags. Other possibilities include masonry, cinderblock and rock.
