Himalayan birch 'Moonbeam' Betula utilis subsp. jacquemontii 'Moonbeam'

Water

The Himalayan birch, or Betula utilis var. jacquemontii 'Moonbeam', should be watered deeply and thoroughly, allowing the water to reach the root zone. During the growing season, watering once or twice a week may be necessary, depending on weather conditions. The soil should be kept consistently moist but not waterlogged. Each watering session should consist of approximately 1-2 gallons of water for young trees, increasing the amount as the tree matures. In the winter, reduce the frequency of watering since the plant's water requirements decrease.

Light

Himalayan birch thrives in full sun to partial shade conditions. The ideal location is one where the tree receives at least 6 hours of direct sunlight daily, although it can tolerate some light afternoon shade. Ensure it is planted in a spot that is well exposed to natural light.

Temperature

Himalayan birch can tolerate a wide range of temperatures, from chilly winters to warm summers. The tree is hardy and can survive temperatures as low as -20°F and up to 90°F, making it suitable for many climates. The ideal temperature range for promoting growth is between 50°F and 70°F.

Pruning

Pruning the Himalayan birch is generally done to remove dead or diseased wood, to shape the tree for aesthetic purposes, or to remove any branches that may pose a hazard. It is best to prune in late fall or winter when the tree is dormant. Prune sparingly, as birches do not respond well to heavy pruning.

Cleaning

As needed

Soil

For the Himalayan birch, a soil mix with a pH of 6.0 to 6.5 is ideal. This plant prefers well-draining soil rich in organic matter, such as a mix of loam, compost, and sand. Regular mulching can help maintain soil moisture and health.

Repotting

Himalayan birch trees do not typically require repotting as they are usually planted directly in the ground. These trees have a fast growth rate and should be given ample space to grow.

Humidity & Misting

Himalayan birches are tolerant to a wide range of humidity levels and do well in outdoor conditions where the humidity fluctuates naturally.

Suitable locations

• Indoor

  Provide bright light, cool temps, and good air circulation.

• Outdoor

  Plant in full sun to part shade, in moist, well-drained soil.

• Hardiness zone

  5-7 USDA

Life cycle

The life of Himalayan Birch 'Moonbeam' begins with seed germination, typically in spring when soil temperatures warm up. Seedlings develop, establishing a root system and sending up shoots that will become the young sapling's trunk and primary branches. As the sapling grows, it undergoes a vigorous period of vegetative growth, characterized by the elongation of the trunk and development of a branching structure, along with the unfurling of its distinctive white-barked limbs and ovate, serrated leaves. After several years, the tree reaches maturity and begins its reproductive phase, producing catkins that contain the flowers; male catkins are long and pendulous, while female catkins are shorter and upright. Following pollination, seeds are produced and dispersed, often by wind, which can lead to new seedlings if they land in a suitable location. The tree can live for many decades, continuing to grow and produce seeds annually, with older trees developing deeply furrowed bark and a stately, broad crown.

  Late Winter-Early Spring

• The Himalayan birch, specifically the Betula utilis subsp. jacquemontii 'Moonbeam', is usually propagated by seed or less commonly by cuttings. The most popular method is by sowing seeds, ideally done in late fall to early winter. The seeds require pre-stratification - a process of simulating winter conditions to break dormancy - which involves storing them in moist sand within a cold frame or refrigerator at 34°F to 41°F (1°C to 5°C) for around 60 to 90 days. After stratification, the seeds should be sown in well-draining soil and lightly covered. They will need consistent moisture and should be kept in a cold greenhouse or a similarly cool environment. Germination can be irregular and may require patience, as it might take several weeks or even months. Once the seedlings have grown sufficiently and after the risk of frost has passed, they can be transplanted to their final position in the garden.
