The climate is only getting more and more extreme, requiring everyone to learn frost protection for plants. Without safeguarding your produce and flowers, they may not return when the seasons change, and temperatures warm again. These tips will help everyone preserve their hard work and keep nature in balance despite frigid winters.
To fight the good fight against the cold, you have to know what frost is, so it explains what happens to your plants. Frost is ice that forms after temperatures drop below freezing, or 32° Fahrenheit. There are two main types to worry about when it comes to plants:
These have different effects on the plants. Hard freezes should be the main inspiration for engaging in frost protection for plants because they can have enduring and irreversible consequences. The cold and ice on top aren’t actually what causes the most damage — it is the water’s movement inside the plant.
As temperatures shift, water moves, solidifies, expands, melts, crystallizes and ruptures. These constant, unexpected movements slowly destroy the plant over time, especially as ice damages cell walls.
This does not diminish the importance of treating outside frost, as well. If frost lingers too long on blades, leaves, petals and produce, it can weigh them down and change their strength. Iced greenery is brittle and more prone to breaking, especially if you are walking in the area. Plants that were previously resilient to occasional bumps by a wild critter or your foot may be unable to survive because of a frost.
The best way to protect lawns, gardens and yards is with proactive maintenance. First, you must find the first frost date of your area. This varies by climate and geography, but you can find it by looking up weather data. Experts determine the expected first frost of the year well in advance, so everyone can prepare.
Then, you can work on a before-the-frost checklist. Frost protection for plants during this period includes:
If you choose to cover plants, you have a few material options. Old bedsheets are a suitable DIY method. Drape everything so it covers the entire plant — all the way to the ground. The heat you secured by watering the soil will emanate and rise from the earth, sustaining the plants. Despite their thinness, the layer is adequate for keeping frost away. You can also use:
Avoid using any type of plastic, as moisture easily sticks to its surface. Unfortunately, this can make the issue worse, freezing itself to plants. Then, removing the cover could cause more damage than the frost would have without it.
Knowing the frost data and completing the checklist is the first step, but there are additional measures to take.
Covers can only protect your plants if you put them on early enough. They have to be settled before the frost hits — not as it is happening or after. They can be removed once the frost melts, but the early evening is the latest time to place them before the coldest temperatures
There are certain species you can prioritize when planning your flowers and garden to improve their chances of surviving a frost. Research native flower varieties to be even more eco-conscious. Cover crops like buckwheat and oats are ideal for this time of year.
If the soil has enough nutrients like potassium, they are more likely to build up resilience before the cold hits to survive the winter. If your garden is missing some essential nutrients, use fertilizers or compost to restore it.
Try not to walk on the grass as much as possible. You can prepare for this by creating designated traversal areas before the frost sets in. This will keep as much of the yard as safe as possible.
Covers are temporary solutions, but more serious actions can be taken. You can use cloches and cold frames to protect small plants more effectively.
Healthy plants thrive because of their foundation. The soil and everything around it must work synergistically to strengthen it for the hard months. This means eliminating reliance on chemicals, increasing the use of organic fertilizers and compost, and, where possible, removing invasive species and weeds.
Many plants may look weathered and destroyed after a frost, but give them time. The preventive measures you took will give it the best chance of reviving once the sun comes back out. You just have to practice patience. While some of the plants may be beyond repair, your work will have saved more than if you had not done anything.
Even if you have never made a conscious effort to safeguard your plants and greenery in the winter, this can be the first season where you do so. It is crucial for everyone to do their part to ensure biodiversity remains strong year-round and that essential resources, such as fruits and vegetables, remain abundant regardless of the season. Frosts are hitting at more erratic times every year, and even in times you may not expect, so preparation is critical to keep flora alive.
