1. Plant them in cloches or cold frames
Cloches are bell-shaped glass covers, also known as bell jars, that help your plants grow even in temperatures considered very low for seeds to germinate. However, you should know that these are very susceptible to wind, so you should always keep the soil leveled before putting the cloche down.
Keep in mind that cloches work better when they have some sort of wind protection, which is why you can try to put them near a wall or a hedge. Though watering plants is considered hard when using a cloche, the soil around it will not only keep it in place, but also keep the plants watered.
Cold frames are very easy to make and they resemble a small greenhouse. Usually, a cold frame is made up of four boards with a removable glass or plastic top. By using solar energy and insulation, your plants will thrive even during the cold months of January and February.
When you use a cold frame, you should keep in mind that though humidity is important to germinate seeds, excessive heat can harm them, even during the winter.
2. Protect Your Potted Plants
If you are planning to have your potted plants outside during winter, you have to make sure that they are plastic pots planted into the ground. There isn’t a clay or stone-like material that will last during winter when temperatures drop below freezing.
By planting the plant directly into the soil, the plastic pot will protect the most important part of the plant, the roots. Just make sure you water them directly and then dig them out when the weather is warmer–most likely in spring.
3. Apply Mulch
Mulch will act as an insulator, which holds heat and moisture for your plants. The easier way to do this is to use mulch made of wheat or pine straws, as it is easy to remove after winter and works well keeping in the heat. This is an easy and affordable way to keep large plants safe. Beware of using too much mulch. With some plants, such as roses, or fruits like strawberries, if you leave them covered for too long, they will not cool down in time for spring.
4. Bring In Your Exotic Plants
There are some plants that will definitely survive the cold weather outside, whether in a cold frame or potted right into the ground, but your exotic plants will not make it outside. The solution is to bring them inside, even if it sounds crazy, tropical plants will thrive when you keep them warm inside, especially when you keep them somewhere moist, like the bathroom or laundry room and when they have a window nearby.
5. Grow Plants That Will Flower During Spring
If you want to have healthy and pretty plants, it might be better to plant bulbs such as daffodils, day lilies or tulips, during the early winter so that by the end of the end of winter, beginning of spring, they will flower.
There are many other tips for keeping your plants alive during the harsh cold season. Make sure you don’t leave potted plants unprotected, water your plants constantly even when they are inside – but be careful about the amount of water, create insulation for your plants, and if needed, even find another source of heat.
We all love to have our gardens looking good during spring, and winter may not be that terrible, but rather a great time to start working towards your perfect plants for the new season.
