Cultivation Advice

Outside all year round, protect the pot to prevent the roots from freezing in winter and shelter it from the wind that is too cold. The burger is less hardy than the palmatum, so it will be necessary to protect it in winter as soon as the temperatures drop below -3°C. On the other hand, it tolerates the sun quite well, but still prefer an eastern exposure to avoid overheating in the middle of summer. It handles hot winds quite well and the leaves are less likely to toast than other Japanese maples. But that's no reason to take unnecessary risks; Grow it in partial shade by watering regularly in summer. In spring and fall, you can put it in full sun to promote small internodes (spring) and beautiful orange colors (in fall).

Maple trees need a substrate that is always moist. Water it regularly while allowing the root ball to dry out slightly between waterings to avoid excess water.  In spring/summer, watering will be done regularly, in hot weather, it's every day ! On the other hand, in winter, water according to the soil monitoring you do. Thanks to the rain and cold, you won't necessarily need to water regularly since the substrate will remain moist.

To do it right: Don't hesitate to water the entire root ball up to the roots, the water will drain through the holes under the pot or bathe it in water (drenching) for a few minutes, to be sure to water it well. We do not recommend putting a cup/container under your pot because the water will stagnate and can cause root rot.  (Too much water = asphyxiation).

Maple trees are understory species that thrive in cool soils. So avoid planting it in a substrate that drains too much or pottery that is too fine. Repot in the spring, every two years, as soon as the buds start to swell.

In the nursery, we use agricultural potting soil which is composed of black peat peat, blond peat, eco-aged, topsoil, horse manure, pozzolana.

During the winter, when the leaves have fallen, you can prune the structure and remove unnecessary branches. During the growing season, shorten the twigs to one pair of leaves with a good pair of scissors.

In the nursery, we use blue tomato/flower fertilizer NPK 12 12 17. Put a handful on the substrate (small or large depending on the size of the pot) from May to October, every 2 months.
