Shield your orchard from winter’s worst. Our guide details the 7 best tarps, from breathable fabrics to heavy-duty covers, all trusted by veteran farmers.
A late spring frost is a fruit grower’s nightmare. You see those perfect, delicate blossoms emerge on your apple and peach trees, a promise of the harvest to come, only for the forecast to predict a sudden plunge below freezing. Protecting those blossoms isn’t just about saving a few flowers; it’s about saving your entire crop for the year.

Frost Protection Basics for Your Home Orchard
The goal of any frost cover is simple: trap the radiant heat coming up from the ground. The earth soaks up solar energy all day and releases it slowly overnight. A good cover creates a microclimate around your tree that can be several degrees warmer than the surrounding air.
The most critical rule is to drape the cover over the tree so it reaches the ground. Don’t just wrap the canopy like a lollipop, and never cinch it around the trunk. You need to create a tent that seals in that precious ground heat. Put your covers on in the late afternoon before the sun sets and temperatures drop, and be sure to remove them in the morning once the frost has melted. Leaving a non-breathable cover on during a sunny day can cook the very blossoms you’re trying to save.
Many beginners grab a cheap plastic sheet, but this can do more harm than good. Standard plastic doesn’t breathe, trapping moisture against the leaves and blossoms. When that moisture refreezes, it causes direct cellular damage, effectively burning the plant. The right material makes all the difference.
Grizzly Tarps: The Heavy-Duty Canvas Standard
When you think of an old-school, reliable solution, you’re thinking of a heavy canvas tarp. These are the gold standard for durability. Made from thick, woven cotton duck, a quality canvas tarp can last for decades if cared for properly.
Their weight is both a benefit and a drawback. On a mature, sturdy apple or pear tree, the heft helps the tarp stay put in a breeze without needing a dozen rocks to hold it down. The woven fabric also has a degree of breathability, which reduces the condensation that plagues plastic tarps. This makes it a bit more forgiving if you’re late getting it off the tree in the morning.
However, that same weight makes them a real chore to handle, especially for one person trying to cover a large tree. They are also expensive upfront and can become incredibly heavy if they get soaked with rain before a frost. For a young tree with a delicate structure, a waterlogged canvas tarp can easily snap branches.
Agfabric Plant Cover: Breathable Frost Blanket
If canvas is the old-school muscle, then modern frost blankets are the lightweight, technical solution. Often sold under brand names like Agfabric, these are made from spun-bonded polypropylene. It feels like a thick, white interfacing fabric and is designed specifically for agricultural use.
The biggest advantage is that this material is highly breathable. Air, sunlight, and even water can pass through it. This means you can leave it on for several days during a prolonged cold snap without worrying about suffocating the tree or causing fungal issues. Its light weight makes it perfect for draping over very young or fragile trees, like a newly planted Japanese maple or a flowering dogwood, without causing damage.
These blankets come in different weights, offering varying degrees of frost protection, typically from 2 to 8 degrees. The downside is their durability. They are prone to tearing on sharp branches or thorns and can be shredded by a strong wind if not secured properly. While not as cheap as a basic poly tarp, they offer a level of plant safety that non-breathable materials just can’t match.
Farm & Fleet Poly Tarp: Top UV-Resistant Pick
The ubiquitous blue poly tarp has a place in the orchard, but you need to choose the right one. The cheap, paper-thin versions will photodegrade and fall apart after just a few weeks in the sun. Look for a heavier-duty poly tarp, often silver or brown, that is specifically labeled as UV-resistant.
A good UV-treated poly tarp from a place like Farm & Fleet or a similar supply store offers an excellent balance of cost, durability, and water resistance. It’s completely waterproof, which is useful if you’re expecting a wet, freezing rain. They are also relatively lightweight and easy to clean and store.
The tradeoff is a big one: zero breathability. You absolutely must vent or remove these tarps first thing in the morning. If the sun hits a tree covered in a poly tarp, the temperature and humidity inside will skyrocket, scalding the foliage and blossoms. Use them for overnight protection only, and make taking them off your first morning chore.
Xpose Safety Rip-Stop Tarp for Easy Handling
For those of us working alone, wrestling a massive, heavy tarp can be the biggest challenge. This is where rip-stop polyethylene tarps shine. They are constructed with a reinforced grid pattern that prevents small tears from becoming large, catastrophic rips.
The main benefit is an excellent strength-to-weight ratio. A rip-stop tarp is significantly lighter than a canvas one of the same size but much tougher than a standard poly tarp. This makes it far easier for a single person to haul it out of the shed and drape it over a 10-foot peach tree without needing a ladder and a helper.
Like other poly tarps, they are not breathable, so the morning removal rule still applies. However, their durability and manageable weight make them a fantastic compromise. They hit a sweet spot for the hobby farmer who needs something tougher than a basic frost blanket but less cumbersome than traditional canvas.
Dayton Burlap Rolls for Wrapping Young Trunks
Frost protection isn’t just about the blossoms in the spring. Young trees, especially those with thin, smooth bark like maples, cherries, and young fruit trees, are highly susceptible to sunscald in the winter. On a cold but sunny day, the sun can heat the south-facing side of the trunk, causing the sap to flow. When the sun sets, the temperature plummets, and the trunk freezes rapidly, killing the active tissue and causing the bark to split open.
Burlap is the classic, time-tested solution. You’re not draping the tree; you’re wrapping the trunk. Starting from the base, wrap the trunk upwards like an athletic bandage, overlapping by about one-third with each turn. Secure it with biodegradable twine, but don’t tie it so tight that you risk girdling the tree as it grows.
This wrapping insulates the trunk, moderating its temperature and preventing the dangerous freeze-thaw cycle. It’s a different tool for a different job. A roll of burlap is an essential piece of kit for anyone with a young home orchard, protecting the long-term health of the tree’s foundational structure.
Planket Frost Protection for Delicate Canopies
Sometimes, you don’t need to cover a whole row of trees. You just need to protect one or two prized specimens, like a dwarf Meyer lemon in a pot or a special Japanese maple. For this, a specialized product like the Planket can be a huge time-saver.
These are essentially pre-made, circular covers, often made from a breathable frost blanket material. They come with built-in grommets or a drawstring around the edge. This design makes them incredibly easy to use: just drape the cover over the small tree or shrub and pull the cord to cinch it loosely at the base. It takes seconds.
The convenience comes at a price; they are significantly more expensive per square foot than buying a large roll of fabric. But for someone with limited time, physical limitations, or just a few specific plants to protect, the ease of deployment and removal can be well worth the extra cost. It’s a targeted solution for a specific need.
Harbor Freight Utility Tarp: A Reliable Value
Let’s be practical. Sometimes you just need to cover something now and you don’t want to spend a lot of money. The humble, inexpensive utility tarp from a place like Harbor Freight is a tool that has saved many a harvest in a pinch.
No one will claim these are top-of-the-line. They are thin, they will break down in the sun over time, and the grommets might pull out if you’re not careful. But they are cheap, widely available, and they absolutely work for short-term, overnight frost protection. For a few dollars, you can get a large tarp that can cover several dwarf trees or one medium-sized one.
This is your emergency option. Buy a couple and keep them folded up in the garden shed. When an unexpected frost appears in the forecast, you’ll have a solution ready to go. Just remember the cardinal rule of all non-breathable tarps: get it off the tree as soon as the sun is up and the danger has passed.
Ultimately, the best winter tarp is the one you have on hand and are willing to use when the temperature drops. Whether it’s a heavy canvas heirloom, a modern breathable fabric, or a cheap utility tarp, the key is preparation. Having the right cover ready before you need it is the difference between a basket full of fruit and a season of disappointment.
