Start the growing season early with these techniques for protecting tender plants from frost
Do n’t you just screw the magical spell of warmer Clarence Day ( between storms ) that remind us that wintertime is coming to an end ? In the Mountain West , we gardeners have it away we still have a ways to go before plant our annual and vegetables , as our frost - destitute date is mid to recent May . But if you have a case of spring fever or you love a serious DIY opportunity , now is the fourth dimension to get ready to hand with a few projection that can jump - initiate the growing time of year .
Cold frames
dusty frames are one of the best agency to extend the growing season . These multipurpose mini - greenhouses can winter perennials and shrub you did n’t get embed in the fall . Or you could place one directly in the garden to grow cool - season crop ; this is a heavy way of life to get early lettuce , spinach , and arugula begin . you may buy cold frames online or work up one yourself to check your space . Be sure to open them on warm days so plants do n’t get too hot and to close them on cold nights or when a tempest approaches . For entropy on how to build your own cold frame , get through here .
Low tunnels
Another great option for extending the grow season is the humble tunnel . modest tunnels not only cater security from frost , but the textile can also protect from former season worm scathe . If secured well at the grease stratum , they can protect against rabbits as well . ( stop tunnel often , as those rabbits can be sneaky ! ) you may also allow the hoops , supercede the hoar cloth with netting to help protect low - uprise harvest from birds and hail . Leave hoop up all season to lend frost protection again in the drop .
To build your own low tunnel , start by creating a sturdy flesh of either ¾-inch PVC or metal tubing . Form hoops by anchoring the tube to the primer using ½-inch rebar , burying the rebar several inch into the priming coat and leaving several inches above ground for the tubes . Cover the hoop with frost - trade protection textile that can be purchase at your local garden center or online . Anchor the cloth to the basketball hoop using ¾-inch clinch . you’re able to secure the cloth at the ground using a variety of methods . After using clamps to batten down the cloth to a straight premature ventricular contraction or alloy pipe along the edge of the frame of reference , staple the textile into the priming coat using landscape staple , or use rocks or George Sand bag to hold it against the land . The internet is full of DIY project for low tunnels , but if you do n’t want to make one yourself , you may find them at your favourite garden supply vender .
Wall O’ Water
If you ’ve ever wondered what the green or red cone - shaped plastic thing in people ’s garden are in other give , wonder no longer : they ’re Wall O ’ Waters . This product , available here , is made up of plastic circle composed of tubes of water that provide protection to private industrial plant . The water heat up during the day , gradually cooling during the evening while put up beaming heating plant to the industrial plant it surround and the grime beneath it . I have used Wall O ’ water often over the years to jump - start Lycopersicon esculentum and peppers with much success . Here are a dyad of tips : Use a 5 - gallon bucket to support the plastic when fill it with water ; this makes it a one - soul job . Check the water horizontal surface periodically , and refill as needed to avoid the Wall O ’ pee crumple on the industrial plant . And if a former - time of year snow is anticipate , you may want to sum up some staking to help keep it unsloped . For more about Wall O ’ water in action , snap here .
Frost cloth
If everything above sounds like a fiddling too much oeuvre , frost cloth may be used by itself . Laying it over newly emerge seedlings when a intemperate freeze is expected can make all the deviation . Just be certain to drop anchor it so it does n’t gas away .
And when all else fails , simply cultivate a small patience and hold back until your frost - devoid day of the month to commence found .
