Create the climate your plants want in your garden. Want to make it warmer in the fall and winter? Cooler in the summer? It takes just a few hours to get started for year-round growing.
The framework for dealing with the different seasons really is a frame. You'll need to create a supporting structure to hold up a variety of fabrics over your plants. In our video on fall planting, Tricia shows the permanent metal frame she built over her raised beds. If you prefer a removable framework you can use our curved pieces of wire for hoops -- simply sink each end 1 foot into your garden soil, spacing the wire supports 4 to 6 feet apart. To make a taller curved hoop, use 10 foot lengths of PVC pipe for the arches. Choose rebar that fits within your PVC pipe. Stabilize the pipe by pounding 1 foot pieces of rebar into the ground at 4 to 6 foot intervals along the sides of your garden bed. Leave 6 inches of rebar above the ground, and pair it with a matching piece on the opposite side of the bed. In late summer, slip the PVC pipes over the rebar to create the tall hoops. When warm weather returns in the spring, remove and store the pipes or leave them in to support any shade cloth you may use during the hot summer months. If you have raised beds with wooden sides you can make permanent PVC pipe arches by attaching the pipes to the outside of the beds. Another option is to make a rectangular framework of PVC pipe. We have snap fittings to connect the lengths of pipe. Just check your pipe diameter and look at our selection of 3-way, 4-way, 5-way, and slip T connectors. This framework can be dismantled for the warm season, or left in place year-round, anchored by rebar.
Keeping the fabric on the frame
Any fabric draped over a framework needs to be secured with clamps or clips. We have aluminum or plastic rowcover clamps to hold fabric onto the structures. To tie the edges of the fabric down to the ground, use our Clip-It or Tufbell Clips, and secure them in the soil with Ground Staples. High winds can play havoc with row covers, so when that becomes a factor in your weather add extra ballast with bags of gravel along one side of your row. Weigh down the other side with boards (for easy removal when you want to harvest or check on your vegetables). Or another secure way to hold down your row cover, greenhouse plastic (Tufflite) or shade cloth is to add an aluminum rowcover clamp over your plastic snap clamps. It provides a super tight connection over your PVC pipe.
Check soil temperature
You may be able to skip the late-summer, soil-cooling step if your soil is a comfortable temperature for the seeds you'll be planting. Most seeds need a temperature of 75°F to 90°F to germinate. Look at your seed packet to see the soil temperature ranges for your seeds, then test the soil temperature at various places in your garden bed with a soil thermometer.
If your soil temperature is not cool enough, water the soil thoroughly to lower the temperature, and install shade cloth on your structure. Clamp the shade cloth in place, then check the soil temperature daily until it is cool enough to plant your seeds. Shade cloth is another great way to reduce the occurrence of sun scald on your tomatoes or peppers.
Floating row covers
Here is a quick overview of the different weights of Agribon row covers we carry, and their uses. If you want the ultimate in sturdy row covers, check out our PVA film.
Add extra warmth to your garden bed, as cold weather approaches, with greenhouse plastic. Another technique used by Eliot Coleman (farms in Maine) is to use a second layer of frost protection in very cold temps. He uses a layer of floating row cover supported by wire hoops over plants in his greenhouse. Want more information about growing in the winter?
