I have apple and pear trees on my plot. I saw them whitewashing trees in the neighboring garden - they say it protects from frost cracks. Is this actually true in 2026, or is it outdated now? What's the best thing to whitewash them with?
Whitewashing tree trunks really does help - it protects against sunburn and temperature fluctuations that cause cracks, especially at the end of winter and early spring 😊 It's best to whitewash in October-November and repeat in February-March while the snow is still on the ground. Use a lime solution (slaked lime with glue or copper sulfate) or special garden paints based on lime - they're breathable and hold up well. It's a simple and time-tested method that's definitely still relevant today, hasn't lost its purpose.
