Whether the plot is big or small, in the country or in the city, virtually every gardener covets a small greenhouse to start seedlings, protect delicate flowers or grow out-of-season herbs and vegetables. Fortunately, enough backyard greenhouse kits are on the market to meet almost every requirement and budget. Here are some of our favorite DIY greenhouses, starting with this beauty from BC Greenhouse. Available from bcgreenhouses.com; prices vary.
DIY or Do It For Me
Offering 81 square feet of floor space, the German-made Riga III is a great greenhouse for the home gardener, including those who prefer to have someone else install their growing space for them. If you buy your own, you can ask a pro to come out to your site to unpack and install the greenhouse, and haul away any packaging and trash. Available at Amazon; $3,750.
Measuring at 8' x 12', this barn-shaped greenhouse has ample growing space for any avid backyard gardener to start seeds, force bulbs, or overwinter perennials. For maximum stability, the greenhouse should be affixed to a concrete or timber base, or attached to the Rion base kit, sold separately. Available on Amazon; $2,459.
Defend Raised Beds
Who says your backyard is too small for a greenhouse? This zippered covering functions much as a greenhouse or cold frame would, and yet is compact and completely portable. Stake it over a raised bed in spring to protect germinating plants or move it over a vegetable patch in fall to protect crops from icy rains. Wherever you choose to place it, it promises to extend your growing season and keep plants healthy. Available on Amazon; $39.98.
This snap-together greenhouse can be entirely assembled without the use of tools. Simply connect the rods, anchor the fixture to the ground with included stakes, and slip the plastic cover over the frame. The sturdy structure is best for use in climates that don't get much snowfall, as harsh winter storms may damage the plastic cover. Still, what this small greenhouse lacks in all-weather durability, it makes up for with its low price. Available on Amazon; $63.69.
