- Protect from frost and moisture in the first winter - this is how it works
- Have shade nets ready - more important in winter than in summer
The local Norway maple was the inspiration for the refinement to spherical maple. A robust winter hardiness is thus laid in the floral cradle of the Acer platanoides Globosum. Nevertheless, winter protection is recommended under certain conditions. This guide explains when and how the safeguards work.
Older maples do not need winter protection
Protect from frost and moisture in the first winter - this is how it works
Stable winter hardiness builds up on the young maple in proportion to the degree of rooting. Under normal conditions, this process is largely completed by the end of the second year. In the first year, it is therefore advisable to protect the sapling from freezing frost and permanent wintry wetness. How to do it right:
- After the autumn planting, cover the root disk with leaves, needle brushwood or compost
- Alternatively, cover the tree disc with a centrally perforated coconut disc (winter protection disc)
The protective layer is removed as soon as the thermometer exceeds the freezing point for several days. Otherwise, condensation could form, increasing the risk of fungal infection.
Have shade nets ready - more important in winter than in summer
If winter comes with a combination of freezing cold and bright sunshine, a shade net should be at hand. Under the influence of fluctuating temperatures, there is a risk of frost cracking in the bark. Therefore, wrap the crown in a breathable mesh. Shade the trunk with reed mats or garden fleece. If you are in a hurry, simply place wooden boards in front of the maple.
Water when there is a frost
A Norway maple suffers damage from drought stress more often in the winter than during the summertime. The roots, which are mainly spread out flat, are denied access to water in the frozen ground more quickly than deep-rooted trees. If there is no snow or rain for a long period of time, the water reserves in the pipelines are quickly exhausted in sunny winter weather. In dry winter weather, water a maple regularly on frost-free days.
tips
In the bucket, a maple is vulnerable to frost every winter. Wrap the pot with winter fleece or coconut mats (€21.90) and place the jar on a block of wood. Please do not forget to water the tree occasionally on frost-free days so that the root ball does not dry out.
