On the flip side, a late killing frost in the spring can nip your hopes for emerging plants in the bud. During the day, plants and soil absorb and store heat from the sun.
As day turns into night, plants quickly begin to lose all their stored heat. Clouds can help insulate and slow the loss of heat, but a clear, wind-free night will afford no protection from frost. Softwoods, actively blooming, and potted plants are the most susceptible to frost damage. The telltale signs are usually visible within two to three days. Browned, mushy leaves and buds sadly greet the unprepared gardener.
The best way to cope with the effects of a sudden freeze is to plan ahead and have plant protection at the ready. Portable, potted plants can be brought into sheltered areas. Plants in large, heavy pots, and those growing directly in the ground, however, need to be covered.
Your first inclination may be to grab a vinyl tarp or plastic trash bags. Not the best idea. Plastic or vinyl materials are normally too thin to provide adequate insulation. Since they do not breathe, moisture can get trapped inside.
If temperatures drop low enough, this moisture will freeze on your plants, causing more harm than good. Instead of plastic, use natural fabrics like cotton or linen, an opened burlap bag, or newspaper.
These materials are thick enough to provide insulation, but allow enough ventilation for moisture to escape. Commercial coverings may be purchased, but you probably already have materials around the house you can use. Bed sheets, for example, work well for covering large plants and shrubs. The important thing is to cover the plants before sunset and be sure the covering reaches the ground beneath the plant.
This way, warmth absorbed into the soil during the day is trapped inside the insulating protection. And remember, frost can even occur in normally frost-free areas, so always pay particular attention to fall and spring weather forecasts. Although he was referring to 18th century fire safety, the words of Ben Franklin hold true for plants, as well.
The best way to avoid frost damage to your plants is to grow plants that can withstand the frost. It is a good idea to ask a qualified local nurseryman what is suitable to grow in your area. Even better, look around your own neighborhood, and see what survives and thrives in other yards and gardens. Choose varieties of plants that flower late, in areas where late spring frosts may occur. Some annual and perennial plants will survive frost on the foliage, but the same frost might kill any flower buds that have emerged.
Cold air is denser than warm air, so it sinks to the lowest point.Grbl wiring
Low-lying areas of the garden can be several degrees colder. Consequently, frost may occur in these areas when there is no frost evident anywhere else in the garden. Plant tender species on higher ground or on slopes where the cold air will flow past the plants as it moves to the low point.
Any sloping area is less prone to frost, because the cold air won't settle there as readily. Precondition your plants to withstand cold temperatures by discontinuing fertilizing in early fall, so that no new foliage is on the plant when cold temperatures arrive. Older leaves are much tougher and more able to withstand frost.
Garden fabric is easy to use: You can drape the cover right over garden plants or use hoops or a wooden frame to support it. Secure the edges of the fabric with soil or use Earth Staples. It keeps heat in, bugs out, and is an excellent windbreak for young transplants. It allows rain and overhead irrigation to reach plants and soil. All-Purpose Garden Fabric will protect plants from frost damage down to 28 degrees F. The fabric can be cut with scissors to fit over conventional-width rows or used as-is for wide-row plantings.
When not being used, the material should be folded and stored away from sun and moisture. Summerweight Fabric is a lightweight garden cover that does not trap as much heat as the All-Purpose Garden Fabric and can be used all season to defend your crops against birds, insects, and the spread of insect-borne diseases.
It transmits up to 85 percent of available sunlight and will not block rain or overhead irrigation. This cover should not be used for frost protection. GardenQuilt is a thicker version of our All-Purpose Fabric, consisting of polypropylene fibers that transmit 60 percent of available light.
GardenQuilt provides excellent frost protection down to 24 degrees F. The thick fabric is ideal for extending the growing season into early spring and late fall, or for insulating strawberries, herbs, perennials, small fruits, and other tender landscape plants all winter long.
Hot, summer sun can affect the lush, moist flavor of homegrown lettuce, making it bitter; a few days of hot sun will make lettuce bolt to seed, ruining it for the season.
These UV-stabilized polyethylene shade net cuts summer sun by 50 percent, while allowing cool air to circulate freely.
Use fiberglass hoops to support the fabric; secure it with clothespins. Prepare the soil and seed the area or plant your transplants. Place the GardenQuilt or All-Purpose fabric directly on the ground or drape it over hoops. We recommend using support hoops for larger transplants, such as peppers or tomatoes, or when covering maturing crops later in the season.
If you lay the row cover directly on the soil, do not stretch the material tight. Leave some slack in the center to allow for expansion as the plants develop.
As the crop grows, it will push the cover up. If you are using support hoops, be sure to pull the cover taut over the hoops and bury the edges well to keep the fabric secure during windy days.Unexpected frosts can leave gardeners scrambling for anything to cover their not-quite-dormant or newly awakening plants.
Grandma used cotton bedsheets and comforters, but in this modern world, it would seem that a modern material like plastic would protect plants significantly better. Plastic can be used in some situations, but most of the time, the old ways are better. It doesn't have to freeze for plants to be damaged by frost; it just has to get cold enough for water vapor to condense on plant tissues that have been chilled to just below freezing. This is exactly what happens during a radiation frost, the most common type of frost event.
During a radiation frost, heat from plants, buildings and even the ground are lost to the still atmosphere. Plant leaves lose heat much more quickly than surrounding objects, the ground and even the air during a radiation frost.
This difference in temperature between the air and leaves encourages the formation of ice crystals that grow through surface cells and thin tissues. When tissues warm above freezing, melting the frost, their contents leak out, causing the death of these punctured cells. For some plants, this kind of damage is no problem -- they may look a little worse for wear, but will continue to grow normally.
Other plants, especially those originating in tropical areas, can't tolerate even the rare frost and may be killed to the ground. Plastic seems like a good idea for frost protection, but it's just too thin to provide any insulation to plants. Since frost forms when leaf temperatures dip, simply covering the plant isn't going to be enough to protect it -- the trick is to use an insulated covering to capture heat that's radiating from the ground.
Plastic that touches plants is even worse than no protection in many cases, since it can hold moisture against plant tissues and cause more serious freeze damage. However, when used as a row cover or placed directly on the ground around a plant, plastic can be an effective tool in the battle against frost.
In general, you should toss plastic covers out of your emergency plant supply closet, but thick bedspreads, cardboard boxes and heavy curtains are still winners. Just ensure that when you cover your plant, the cover reaches the ground, trapping warm air under the plant's canopy.
The better the cover does this, the safer your plant will be from frost. In areas where frost is frequent and unpredictable, gardeners often erect tall stakes or forms around their frost-sensitive plants so they can drape their covers over the plants and secure them without worrying about the coverings bunching or blowing away in the night.

So when the frost is coming, be sure to cover up your tender plants. Bedsheets, plastic, straw, hay, mulch, leaves, and anything else you have on hand that will insulate will do the trick in protecting your plants. The reason for this is so the condensation that collects under the cloth will not refreeze and still kill your plants by freezing.2008 ford 4 6l engine diagram diagram base website engine
Giving your plant some clothes on a cold night can be the difference between a total bust and an amazing garden. You can buy a multipurpose garden fabric here :. I mean to either hope you have fog in the morning or build a fire only to let it smolder overnight. All you have to do is start a fire and let it smoke and smolder. This allows a blanket of smoke to cover your plants instead of a blanket of condensation.
Fog works the same way. If you have fog during extremely cold temperatures, it will lay on your plants like a blanket and offer protection. So before you ultimately do anything, check the weather.
See if the fog is coming in with the cold. If you have small children and watch a lot of Mickey Mouse Clubhouse then you probably just busted out laughing. You can see what I mean here. Either way, if the water is constantly touching the plants, then no ice is able to form. Therefore, your plants will be protected when you wake up in the morning. The key to this working properly is a light amount of water or mist and also to be sure that the water is constant during freezing temperatures.
So just keeping a soaker hose running or light sprinkler going should be enough to protect your plants from freezing. All you have to do is build a fire and instead of letting it smolder as I mentioned earlier just keep it going.
Big farms and vineyards are known for using this option. They say it is costly because of fuel and labor. However, if you are homesteading, you most likely use family to help you and burn your own wood. But if you are up for pulling an all-nighter, this is a great option for you and very cost-effective as well. This option is just about fully watering the dirt around the plants.Plant Pot Frost Control Covers
You can purchase antitranspirant here. This does require you to buy an outside product but if you are wanting an easier method to keep your plants from freezing this could be it. A lot of people especially urban homesteaders plant a lot of their produce in pots.
This is a great option for them since all of their produce can be easily moved to any location desired. You do this by tying your plant up, so it is nice and tall.
Then put a stake in the ground to secure it. After you tie and stake the plant up, then you wrap burlap around it like a fence.
When done adding the burlap, you then stuff the inside with mulch, leaves, or hay. This insulates the plant and keeps it from freezing. Okay, I seriously doubt anyone is going to be hanging out with their plants in a frost with party hats on their heads and blaring party music.
However, if you feel so inclined to do that there is no judgment here.Most gardeners keep fabrics and covers on hand to protect plants from cold. You can also purchase frost blankets that give varying degrees of frost protection. Another reason to cover plants is for protection from wind, sun, hail and pests, and floating row covers are the ideal material for this.
Frost protection should be removed every day, but row covers can remain in place for weeks or months. When the weather begins to dip, it can affect the plants and shrubs. Plants at 39 degrees can begin to feel the chill and require a cover just to be safe. Blankets, bed sheets, burlap and even old comforters wind up protecting garden plants in winter. Garden centers sell various weights of covers.
Heavier weights with thicker material called frost blankets can protect against 8 degrees of frost. Midweight row covers provide 2 to 4 degrees of protection. Support covers with frameworks or stakes so they don't touch the foliage. Allow enough overhang so the cover edge rests flat on the ground. Hold the edge down with rocks or sandbags so the cover doesn't blow away and the heat stays under the cover. Frost covers stay on overnight. Put stakes and frameworks around plants in advance of predicted cold to lessen your workload when frost is due.
Place frost covers over the plants before sunset so you can capture the ground heat, which will slowly re-radiate beneath the frost blanket during the night.
The next day, once temperatures rise above freezing, remove the covers so the sunlight can reheat the ground. Dry the covers out before reusing them if they become wet. You can layer frost covers, depending on the degree of cold expected. Start with a frost blanket if a low temperature of 29 degrees Fahrenheit is predicted.
Add a layer of plastic sheeting over the top if temperatures are expected to drop several degrees lower. Remove the next morning. Row covers have many built-in pores that allow air exchange and let in light. Because of this, row covers can stay on a longer time than frost covers. Midweight row covers admit 75 to 85 percent of available light, yet buffer strong winds and let rain in. Lightweight row covers admit 95 percent of available light.
Both weights exclude pests like aphids, caterpillars, squash bugs, cucumber beetles and birds if you seal the edges of the cover against the soil. If your crops, such as squash, tomatoes and peppers, need pollination, remove the row covers when the plant flowers to admit pollinators. For leafy greens, keep covers on until you want to harvest the crop. For warm-season vegetables, leave the covers on longer. Remove row covers from tomatoes with ripe fruits for easier harvest and for increasing late summer light levels.
Plants that need pollinating should have the covers lifted slightly so that bees and other pollinators can easily travel in and out of the covered garden bed. Allow wind to circulate as well to give the flowers an opportunity to pollinate naturally.
