In the face of native maple giants, such as sycamore and Norway maple, there is no doubt about a robust winter hardiness. However, small maple species in tubs raise the question of whether they can survive a Central European winter with biting frost unscathed. This guide explains the circumstances under which winter protection is recommended for maple trees.

Larger maples are well hardy

Young maple trees need winter protection - here's how to do it right

In the year of planting and the following two to five years, a maple is busy gradually building up its winter hardiness. Until then, the tree or shrub needs protection from severe frost. The following precautions have proven successful in garden practice:

  • Before the first frost, cover the root disc with a 5 to 10 cm thick layer of leaves, compost or bark mulch
  • Cover the young shoots with a breathable fleece in the year of planting
  • In later years, when the sun is blazing and there is heavy frost, cover a shading net

Also protect the trunk of the young maple tree from intense winter sun. When temperatures rise after a frosty night in direct sunlight, the bark can crack. Leaning some planks against the trunk will prevent this damage. Alternatively, wrap the tree trunk with reed or coconut mats. (21.90 €)

Protect maple in the tub from frost every year - this is how it works

Maple varieties with shrub-like and small growth are ideal for life in large pots. This form of cultivation makes the root ball behind the vessel walls vulnerable to frost. With the following precautions you strengthen the winter hardiness of maple trees in the tub:

  • Before the onset of winter, move the tub to a sheltered niche
  • Place on wooden or styrofoam plates
  • Cover the pot with fleece, foil or coconut mats
  • Layer autumn leaves, straw or bark mulch on the substrate

It is important to note that under this winter protection, the root ball is threatened by drought stress. Therefore, water regularly on mild days.

tips

If winter returns at the time the leaves sprout, frost damage is sometimes reported on slotted maple varieties (Acer palmatum). Wilted leaves and limp shoot tips are typical symptoms of the dilemma. First wait a few weeks to see whether the tree will regenerate on its own. Only then should you cut the frozen branches back into the healthy wood.
