Many of you have reached out to me about building raised garden beds this summer.  After our seemingly endless winter, the sun is shining today and our temperature should top 60 degrees.  It's really time to start gardening! 

I swear by the method of dense companion planting in raised beds (read Sally Jean Cunningham's Great Garden Companions - it's my "go to" gardening bible).  Planting your crops close together, with herbs and flowers interspersed amongst them, will eliminate the empty spaces where weeds might take root.  And if you line your beds with "hardware cloth" (1/2" wire mesh that you can find at Home Depot or Lowe's), the burrowing critters won't be able to find their way to your crops.  Most importantly, raised beds will save your back when you're tending the garden!

I've built two types of raised beds and they're both attractive and durable.  The first type - which is less costly, but more labor intensive (perfect for experienced DIY-ers) - was described in detail in an earlier post

The second type uses Raised Bed Corners and In-Line Connectors from Gardener's Supply Company and assembles in minutes. For a 12" high bed, all you need are the 12" raised bed corners and two rows of 2x6 lumber (see photo above of our expansion, half completed, with one row of 2x6 lumber already in place). Size possibilities are endless and you can even create beds that have sections of varying heights. Just make sure to purchase lumber that corresponds to the size of the corners and connectors that you intend to use. Include the in-line connectors if you plan to construct beds that are longer than 8 feet.

I used untreated cedar, but the National Gardening Association says that new ACQ pressure treated lumber is safe for vegetable gardens too.  My local lumberyard, Speonk Lumber, cut the cedar boards for me so that all I needed to do was slip each board into the slots in the raised bed corners and insert a screw to hold it all together.

Once I assembled my garden beds, I combined equal amounts of organic topsoil and compost from my local garden center (ordered for my initial beds by the cubic yard, which is far less expensive than purchasing by the bag), along with some peat, and shoveled everything into the beds.  To figure out how much soil mix I needed, I multiplied together the length, width and height of my bed in feet, and then divided by 27 to obtain the number of cubic yards of soil mix.  For my first beds, which were 18" high and 4' wide by 8' long, I needed (1.5 x 4 x 8) / 27 = 1.8 cubic yards of soil mix.

The only thing I had left to do was add water and seeds.  Providing a regular supply of water to your garden beds is critical.  In my 4' wide beds, I have three parallel lengths of drip hose running down each bed to ensure that every plant in the bed has access to an adequate water supply (see photo).  My irrigation operates on a timer, and I water before sunrise each day to ensure that the water goes directly to my plants' roots and doesn't evaporate in the heat of the day. Gardeners.com sells Aquacorners and DIY drip systems.  Although I didn't use them in my garden beds, they are well-reviewed on the Gardeners.com web site.

Rome wasn't built in a day.  But my garden beds were.  If you've been thinking about starting a garden, now's the time.  In the northeast, where I live, it's time to plant peas, lettuces, spinach, radishes and a host of other cool weather crops.  I'll have my hands in the dirt this weekend.  What are you waiting for?
