How to Help Outdoor Roses Survive Winter
This article provides useful gardening tips on how to help outdoor roses survive the winter, which may be of great help to you. Let's take a look!
How to Help Outdoor Roses Survive Winter
Use Plastic Film: If you want your roses to survive outdoors during winter, you need to build a frame and cover it with transparent plastic film. Control Temperature: Keep the temperature around 18 degrees Celsius. Reduce Watering: Water evaporation is slow in winter, and the plant's absorption capacity is weak. Prune Branches: Cut off the dead, weak, diseased branches, and the tender branches that sprout in autumn.
1. -- Using Plastic Film --
If you want your roses to survive outdoors during winter, certain measures for insulation need to be taken. First, build a frame around the roses with wire, then cover the frame with transparent plastic film, and finally secure the plastic film with strings. Also, make a few small holes in the plastic film for ventilation.
2. -- Controlling Temperature --
Roses are somewhat cold-tolerant and can withstand temperatures as low as -15 degrees Celsius. They enter dormancy when the temperature drops below 5 degrees, with the optimal growth temperature being between 15-26 degrees. When grown outdoors in winter, it's best to keep the temperature around 18 degrees Celsius and ensure at least 6 hours of sunlight per day.
3. -- Reducing Watering --
In winter, roses usually enter a dormant period. When grown outdoors, they typically do not require watering. Since water evaporates slowly in winter and the plant's absorption capacity decreases during dormancy, excessive water can lead to frost in the soil. Therefore, it's sufficient to water once with an antifreeze water before winter arrives.
4. -- Pruning Branches --
When the temperature drops below 5 degrees, you need to prune the roses appropriately. First, cut off the dead, weak, diseased branches, and the tender branches that sprout in autumn. After pruning, water once with a root-setting water, spray with diluted organic nutrient solution, and then cover with straw for insulation.
