With a picturesque slotted maple, the magic of Asia will find its way into your garden. So that the popular ornamental tree can unfold its floral magic perfectly, it depends on the right care. Do you still have questions about watering, fertilizing, cutting and wintering? Then read well-founded answers here.

Slotted maple in the pot should be fertilized

How do I water slotted maple correctly?

The root system on slotted maple runs mostly flat and close to the surface. Proper watering not only serves to supply water, but also makes a valuable contribution to the advantageous deep growth of the roots. That is how it goes:

  • In case of dryness, pour the water directly onto the root disc
  • Water deeply 2 to 3 times a week instead of small amounts every day

With slotted maple in the tub, let the water slowly run out of the can spout onto the substrate until the first drops run out of the bottom opening. Water again only when the substrate surface has dried noticeably.

Is Japanese maple dependent on regular fertilization?

In the bed, the one-off application of fertilizer covers the nutrient requirement. In the fall or spring, give mature compost with horn shavings (32.93€) and water again. Slotted maple in pots should be fertilized every 4 weeks from April to September with a commercial green plant fertilizer in liquid form.

Is cutting part of the maintenance program?

Slow-growing slot maple varieties naturally develop a compact shape and do not tend to age. Cutting measures are rarely on the agenda here.

Fast-growing cultivated forms sometimes tend to grow sparsely and tolerate a beauty cut. The best time is in the transition from hibernation to the growing season. It is important to note that you limit the pruning to the one-year-old wood. Acer palmatum is very reluctant to sprout again from old wood.

When does winter protection make sense?

Slotted maple must gradually acquire a stable winter hardiness. The wood in the bed is threatened by frost damage, especially during the first 5 years. Therefore, before the onset of winter, cover the root disc with a 5 to 10 cm thick layer of leaves, fixed with needle brushwood. A breathable fleece hood protects the branches from the harmful combination of freezing frost and blazing sun.

tips

All efforts for a competent care program will come to nothing if you assign your slotted maple to an unsuitable location. The pivotal point for vital growth and an opulent foliage are sunny to partially shaded, wind-protected locations with sandy-humic loam.
