In all honesty, you could probably just let hardy outside plants take care of themselves during the winter, and they’d probably be fine. (Can you tell that I practice pretty laissez-faire plant parenting?) However, if you’re a superb plant parent, follow these simple instructions to ensure that your outdoor plants have the most relaxing winter hibernation ever.
Know Your Plants
You should first inventory all of your current plants. Determine which plants are annuals and perennials, if you don’t already know. Annuals have a single growing season and won’t return after the winter. Common annual flowers that can be easily removed and composted include geraniums, sunflowers, marigolds, and zinnias.
Bring any tropical or subtropical plants inside as well. Even though they may thrive outdoors in the summer, ferns and palms aren’t sturdy enough to endure winter conditions like snow and freezing temperatures. Just be careful to inspect them for bugs before you bring them inside, or else you run the risk of having bugs infest all of your other plants (a mistake I’ve made several times).
How can plants be kept alive outside throughout the winter?
I’ve only recently started gardening in the winter, so I was concerned that the cold would kill my plants. This is the result of some time I invested in research and testing several ideas.
You must give outdoor plants enough of water if you want them to survive the winter. Mulch the soil after it has been watered to keep the moisture and warmth in. To avoid frost, cover and enclose the plants as needed.
Different plants will require different care, and there are proper and wrong ways to go about it. If you follow the appropriate instructions, keeping your plants alive during the winter is not difficult.
How should outside potted plants be cared for during the winter?
You might need to give your pots additional protection depending on where you reside. The following are a few choices for overwintering containers:
- Put many pots next to the house or wall on the ground. Put the cold-hardiest plants outside the grouping, and the weaker ones in the middle. Place straw bales around the outside. Putting them together improves the insulation’s mass and volume, shielding them from chilly breezes that could cause freezing and desiccation.
- Mulch pots with straw, mulch, or chopped leaves for further insulation. Snow is a wonderful insulator as well. Grouping pots in a premade pond liner and filling it with mulch is an intriguing concept for insulating containers.
- The only insulation for roots is the wall of the pot itself because the majority of roots usually tend to be on the exterior of the rootball. To insulate roots, place foam along the walls of square pots that is at least an inch thick before planting. Fill the internal walls of rounded pots with foam peanuts.
- Fill the container up with soil and bury the pots there.
- Plant the rootball in the ground after removing it from the container. Clean the container, then keep it inside. Next year, remove the root ball and repot it in the same or a bigger container.
- Burlap, bubble wrap, old blankets, or geotextile blankets can all be used to wrap pots. Since the roots require protection, the entire plant doesn’t need to be covered. The root zone will retain heat thanks to the support of these protective covers.
- Cover plants at night with cloth, burlap, or plastic if low temperatures are anticipated. If you use plastic, make sure to take it off during the day because the heat can hasten the growth of the buds. Additionally, when covering, take care not to harm the plants’ tops. Plant damage from the cold and pests is facilitated by injury.
- To offer further security, place your pot inside of a larger pot. The bigger pot should have extra insulation or sturdy walls for this to work optimally.
Hard freezes may be unusual to nonexistent in USDA Zones 7 through 11, therefore it may not be essential to add insulation or move pots indoors for the winter. There are several tasks, nevertheless, that you should still be mindful of. Plant development will stall in the winter because of the lower temperatures, and watering may become less regular. However, salt can accumulate in the soil and increase toxicity levels. Leach the salts out with water. As required, fertilize plants as well.
Can I keep potted plants outside over the winter?
Clean up any empty pots before storing them as the first step in winterizing the container garden. Clay and terra-cotta pots should be kept dry and upside-down or on their sides. Most terra-cotta pots shouldn’t be left outside in frigid weather because they could crack or break because they are constructed of porous clays. Choose terra cotta pots made of special clay that can withstand freezes if you must leave them outside (like Impruneta, for example). Terra-cotta pots typically do not hold up as well to freezing as glaze-coated pots, which are typically fired at higher temperatures.
Wrap the sides of planted terra-cotta and glazed containers with layers of bubble wrap or burlap coated in plastic to keep them safe when left outside.
Once the plants go dormant and their water needs are reduced, wrap them to prevent them from absorbing any more moisture. (Wrap containers holding
After the first hard frost, wrap evergreen plants in plastic.) If you have empty concrete, cement, or clay pots that are too heavy to move, clean them as thoroughly as possible.
In order to avoid water from building up within the pots, freezing, and cracking them, fill them as much as possible and cover them with lids or plastic sheeting. Although certain plastic pots may shatter if the soil inside expands during freezing temperatures, sturdy plastic and fiberglass pots are perfect for leaving outside. Durable hardwood-made wooden containers are also appropriate and will deteriorate gracefully over time.
In the winter, should you cover outside plants?
While some people will haphazardly cover a shrub, Reeves said that is probably not the best course of action.
The edges of the cover you select should be firmly fixed to the ground instead. For this, you can use rocks, firewood, or bricks.
Even though the leaves appear to be scorched, hold off on pruning shrubs until April. Walter Reeves contributed a piece.
Because their roots are not in the ground, container plants are particularly susceptible to the cold. Plants should ideally be relocated inside a garage, shed, or basement. Put them close together and cover them if you’re going to leave them outside. To keep the containers warm, wrap them in plastic or burlap.
Perennials and newly planted trees and shrubs can be shielded from the cold by a coating of mulch. Mulch serves to add an additional layer of defense against the soil’s ability to drive some shallow roots out of the ground as it freezes and thaws, making them even more vulnerable. To prevent rot, just be sure to keep the mulch a few inches away from the plant.
Wrap the trunk of any young trees or trees with thin bark (such as some fruit trees) with a trunk wrap. Otherwise, the bark can crack because it swells in warm weather and shrinks in cold weather.
Keep your plants warmbut not too warm
Many plants are particularly sensitive to cold air. Make sure they are shielded from the cold air as the first step in winter plant care. By insulating your home’s doors and caulking your windows, you can partially fix this problem. Additionally, during the hot months, if you store plants next to exterior doors or on leaky windowsills, make sure to relocate them to places where they won’t be stunned by the chilly air.
Keeping plants away from heat sources like fireplaces, radiators, and even heating vents is also a good idea. Blasts of hot air can harm your plant just as much as blasts of cold air. For the optimal conditions for plant life, keep your plants at a constant temperature of 65 to 75 degrees F (18 to 24 degrees C) during the day and above 50 degrees F (10 to 10 C) at night.
Reduce your watering and use warm water for plants in winter
The majority of houseplants “dorm” throughout the fall and winter even though they are inside. With less light, plants will grow slower and use less water and fertilizer. As a result, your indoor plants may require less feeding over the winter.
Observe the general recommendations for watering and only apply water if the soil is dry an inch or two below the surface. Keep in mind that leaving your plants submerged in water can result in root rot, fungus, mold, and a number of other problems. If you notice yellow leaves or moldy soil, you should lessen how often you water your plants. In the winter, you might also wish to give your plants warm water. It is best to water plants with warm water in the winter since it not only promotes faster and greater plant growth, but it also keeps the plants warm.
We advise you to stick to the typical “once per week” schedule used by most houseplant owners in order to maintain consistency and avoid disrupting the rhythm. But on the days you water your plants once a week, merely cut back on the water you give them by 25 to 50 percent.
Increase your home’s humidity
Low humidity during the winter months is a problem for both people and plants. Keep your humidifier on if you have one because plants prefer humidity levels of roughly 50–60%. If not, try grouping your plants in your home’s most humid areas—typically the bathrooms or kitchen—or setting them on top of a sizable tray or baking sheet that is moistened with water. Place some stones in the water, then place the plants on top of the stones (you just need to make sure the pots don’t touch the water).
Clean your plants
In the winter, the sun is scarce. Make sure the leaves of your indoor plants stay clean and dust-free so they can make the most of the little amount of light they receive. Put your plants in the bathtub once or twice a month, and give the leaves a gently rinse with a handheld sprayer or wipe them down with a moist towel to remove dirt and grime. Keeping the leaves clean will increase their capacity for photosynthesis.
Give them plenty of light
The final tip for maintaining indoor plant life is to remember that during the fall and winter, plants require light more than anything else. To ensure that every plant receives the necessary amount of sunlight, you must rotate your pots with extreme care. Use a full-spectrum lightbulb in a typical desk lamp to shine it on your plants for at least 12 to 14 hours each day if the amount of natural sunlight available is insufficient. Find out more about how to set up a grow light or buy an LED grow light from our shop.
As a final piece of advice, it’s important to remember that some of the suggestions we make in this post call for adjusting many variables.
For instance, if you relocate your plants away from a drafty window, the amount of light they receive will almost surely change, and possibly the humidity will as well. For this reason, after you’ve moved your plants, keep an eye on them every day. To get it correct, you might need to try a few different things or need to go back and undo some modifications.
What should I do with my plants over the winter?
To ensure they receive enough light, place indoor plants close to a window, but keep them away from drafts and other chilly air currents. Avoid cracking open windows near plants, and check the condition of your window insulation.
Can you leave plants in plastic containers outside?
Nurseries must maintain the health of the plants while safeguarding them from threats such as sudden frost and nosy visitors. Peat moss, pressed paper, and composted cow manure are just a few plant pot materials that are promoted for their biodegradability and minimal environmental impact. Their concern for the environment goes beyond organic fertilizers and native plants to encompass advances in containers. However, because these pots might break down in the soil, especially after watering, handling expenses and unintentional plant harm may rise. Large perennial plants and trees are especially well-protected in more robust containers, which are typically made of plastic, until you purchase them.
When the season is over, what should you do with your potted plants?
Ten things to do:
- 1.) Don’t just clean, “sanitize.
- 2. Remove the dead materials.
- 3. Cut off the wilted perennial flowers.
- 4.) “Put compost on top of the gardens.
- 5. One final grass cutting.
- 6.) Apply lawn fertilizer.
- 7.) Guard the delicate material.
- 8. Examine the mulch.
Once fall arrives, when should I cover my plants?
We are lucky to be able to cultivate semi-tropical and/or tropical plants, such Bougainvillea, Lantana, and Yellow Bells, outdoors if we reside in regions with moderate winters.
The frost-sensitive plants, whose vibrant blossoms we love in the summer, frequently require additional care in the winter. When is the final frost? Even gardeners in chilly climates have to make a guess.
Damage to the leaves and occasionally even to the roots can happen when temperatures fall between 32 and 24 degrees F.
How to Protect Plants From Frost
What can you do, then, to help safeguard your frost-sensitive plants? During the chilly nighttime hours, cover them. The soil absorbs the heat of the sun during the day. When plants are covered in the evening, the heat that the earth radiates back into the night is trapped by the covering.
What Should You Cover Plants With?
You might be unsure about the best coverings to use on your frost-sensitive plants.
You might do as we do and go through your linen cupboard for used blankets, sheets, and towels. Of course, burlap and frost cloth purchased from your local nursery work great as well. Frost protection fabric is available on Amazon.
Are plants protected from freezing by a sheet?
QUESTION: Fabric or plastic is the best material to use as a cover to shield outside plants from the chilly air.
When the temperature drops low enough to cause the moisture on plant leaves and buds to freeze, the threat of frost typically materializes overnight. You must cover plants to prevent the moisture from freezing in order to protect them from cold. It’s crucial to utilize the proper materials, even though an unexpected cold can leave many gardeners racing to find something to cover their sensitive plants.
It is ideal to use a cotton covering because it will let moisture out while yet shielding your plants from cold. Fabric coverings will both capture the heat that is radiating from the ground and stop the freezing air from coming into direct contact with the wetness on the plant. Large plants and shrubs are best covered with bed linens or comforters. Newspaper can be used to low-growing vegetation, but it can frequently be challenging to make it stay put. I have recycled old towels, sheets, and even cardboard boxes as well as pillowcases. Whatever you choose to use to cover your plant, just make sure the canopy traps the warm air within and extends to the ground.
You can use plastic, but it’s crucial to remember that you shouldn’t let it touch your plants. Because it can hold moisture against plant tissues and worsen freezing damage, plastic that comes into contact with your plants is frequently much worse than no protection. For their frost-sensitive plants, many gardeners will frequently install high stakes or forms so they can cover them and secure them without worrying about the coverings blowing away at night or harming the branches. As long as the plastic won’t come in contact with the plant in any manner, it is acceptable to cover a structure like this with plastic.
And keep in mind that the more cover layers there are, the better the insulation is. So, feel free to cover priceless or delicate plants with more than one cover, especially during really cold temperatures. You may, for instance, cover the plant with a sheet of plastic and then an old blanket.
Whatever method you choose, it’s crucial to remove the covering as soon as the risk of frost has gone so that the plant can absorb light and to avoid heat buildup when the sun comes out.
