With the maple, the name says it all. But it's not just its spherical shape that makes it so popular in our gardens. It is also very easy to care for.

The maple is created by the so-called head finishing from the maple. It takes its name from the spherical tree top. The leaves show the shape typical of maple leaves: serrated several times and growing in umbels. In autumn, depending on the variety, the leaves change from golden yellow to bright red. In spring, the maple also forms winged seeds. Because of the beautiful shape and the pretty leaves, the ornamental tree is often planted in the garden.

  • Family: Soap tree family
  • Subfamily: Horse chestnut plants
  • Genus: Maples
  • Species: Norway maple / Acer platanoides
  • Botanical name: Globosum

The maple tree is between three and five meters high and is very garden-friendly due to its low height. But keep in mind: the tree top is protruding and can be up to a few meters in diameter, which is why the tree therefore needs a lot of distance from the house wall. It is perfect for the home garden and can also be planted in a large tub, then it will remain even smaller due to the restricted growing conditions.

The round crown develops its shape by itself. A form cut is therefore not necessary. The scissors should only be used if the tree top becomes too lush. Generally the tree grows rather slowly. The final height will therefore only be reached after a few years. The trunk, which is currently growing, develops a strong scope.

Location and soil conditions

The maple loves light and sun, so it also tolerates great heat. However, he likes wind less, which is why a protected location is ideal. The tree does not make any special demands on the ground, the ground should only not be too acidic. For example, normal garden soil mixed with compost is optimal. The size of the planting hole is more important because the roots need a lot of space. A planting hole that corresponds to the circumference of the tree crown is ideal. You have to loosen the subsoil well so that the roots can grow into the depth unhindered.

Incidentally, you can plant maples in any season when the weather is frost-free. However, after planting and in the first few weeks after planting, keep in mind that the maple requires a lot of water. Watering once a week is sufficient later. After a year, the tree has grown well and does not need any additional water, except during very long and warm dry periods.

Important care measures

To water:

It is better to water less often, but then abundantly. The reason for this is the "parenting effect" for the roots. When the water supply is running, the roots remain flat. Dry earth, on the other hand, means that the tree forms roots deep down and is better able to take care of itself.

Fertilize:

The maple doesn't need any fertilizer. In spring, you can still enrich the parent environment with compost.

Cut:

A topiary is also not necessary. If necessary, you can remove dead branches and thin out a too dense, lush crown.

Wintering:

The tree is frost-resistant and hardy. It can therefore easily survive the cold season without special winter protection.

Combat the most common diseases and pests

❒ Powdery mildew:

Insects can hardly be dangerous to the maple, because healthy maples are resistant and robust. Powdery mildew can occasionally appear, but this usually disappears on its own. It is only important that you remove infected leaves. If there is more infestation, it helps to spray the trees with a milk-water mixture (9 parts water, 1 part milk) or a baking powder-water mixture (5 liters of water, 3 packets of baking powder).

❒ Verticillium wilt:

Verticillium wilt caused by a fungus may also occur. The fungus clogs the water pipes and causes the leaves to wither. Fresh shoots, on the other hand, die immediately. Infested shoots must be cut out in the event of an infestation. Another fight is difficult. With all fungal diseases, the use of fungicides is also advisable.

❒ red pustule:

Red pustule is also a fungus that mainly affects dead or weakened wood. You can recognize the disease by orange or red growths. The tree bark also changes color. Such an infestation is difficult to combat. As an immediate measure, it helps if you cut away all affected areas and burn the cut, i.e. do not throw it on the compost. Otherwise it could happen that the fungal spores spread further.
