Generally speaking, Field Maples are pretty tough customers when it comes to frost. However, young plants aren’t always quite as resilient against the cold as their older counterparts. With a few simple steps, you can protect your Field Maple hedge and get it safely through the winter months. Here’s how to do it.
Extra Care During the First Year
If you’ve just planted your hedge, keep in mind that it isn’t fully ready to handle a deep freeze yet. The roots haven’t had enough time to really anchor themselves deep into the soil, and that signature winter hardiness takes a little time to develop. During that first year, you’ll definitely want to follow these tips:
What to keep in mind:
- Give your Field Maple plenty of room by planting it in a generously sized hole.
- Use a bit of compost and steer clear of mineral fertilizers for now.
- Make sure to give the plants a good soak for several weeks after planting.
- Spread a layer of brushwood or fallen leaves over the root zone for insulation.
Potassium: The Secret to Cold Resistance
Field Maples often show off with a big growth spurt once they settle into a new spot, so a little nutritional boost never hurts. The best time to help them out is in September or later in the fall by applying a potassium-rich fertilizer. This specifically supports the Field Maple’s growth process.
But potassium isn’t just about growing tall; it’s a game-changer for frost resistance. By using a potassium-heavy fertilizer (like potash), you’re actually strengthening the plant’s cell walls. This prevents the fluid inside the cells from freezing as easily, helping your Field Maple handle those plummeting temperatures.
Finally, try placing some brushwood or evergreen branches over the roots. If you tuck the branches slightly into the soil, they won’t blow away in a winter storm. This layer acts like a blanket, preventing the biting wind from freezing the ground too quickly and keeping the roots near the trunk nice and cozy. This extra bit of protection ensures your hedge will bounce back in the spring, providing you with that beautiful, leafy privacy screen we all love.
