Why Raspberries Freeze in Winter: These 3 Actions Are to Blame
09.02.2025 04:10
Raspberries freeze not only because of frosts, but also because of non-obvious mistakes made by gardeners.
To prevent this from happening, you need to correct three main mistakes that lead to raspberry freezing.
Late nitrogen fertilization
Raspberries need nitrogen fertilizers and organic matter, but only in summer.
If you feed raspberries with them at the end of summer or in autumn, the shoots will not have time to prepare for winter and may die.
They continue to grow, the sap flow does not stop and the buds on the roots wake up.
As a result, the raspberries go into winter weakened and can easily freeze.
In addition, nitrogen affects plant tissues and makes them more vulnerable to frost.
The cells become loose and when frozen, ice crystals destroy them.
Raspberry protection
To protect raspberries from frost, switch to potassium-phosphorus fertilizers from the end of summer.
They help the shoots to mature and prepare for the cold weather.
Abundant watering
Raspberries love moisture. However, excess water in August-September can be very harmful to them.
Shoots that are saturated with water will tolerate frost worse.
Also, overdried shoots will suffer from the cold and become brittle.
