Betula utilis is a deciduous tree that is native to the Himalayan region. It typically grows to a height of 30-40 m (98-130 ft) and has a trunk diameter of 1-1.5 m (3.3-4.9 ft). The bark is smooth and reddish-brown in color. The leaves are ovate-shaped and have a serrated margin. The flowers are small and yellow-colored. The fruit is a small, woody cone.

About soil condition, Birch grows in a wide range of soil types, from well-drained sandy soils to heavy clay soils, and even tolerates occurs on sites that are seasonally waterlogged. It is not, however, able to tolerate waterlogged soils that are poorly drained for long periods.
So, like the other trees, the Betula utilis needs sun to grow. It is a deciduous tree, meaning it sheds its leaves in the fall, and needs sunlight to produce food for itself in the spring and summer. The Betula utilis can tolerate partial sun, but it grows best in full sun.
The temperature condition that is best for Betula utilis is cool to cold. The tree does not tolerate heat well and will experience significant stress if the temperatures get too high. The leaves of the tree will begin to wilt and the tree will eventually die if the temperatures remain high for an extended period of time. The tree does best in temperatures that are below 70 degrees Fahrenheit.
Ideal humidity condition for this plant is 50%. If the humidity drops below 30%, the leaves will start to turn brown and drop off. If the humidity is too high, the leaves will become yellow and start to drop off as well.
Mentioning fertilizer, this family of plant requires a lot of attention when it comes to keeping them healthy. If the leaves turn yellow, it could be a sign of over-fertilization. Also, too much fertilizer can lead to root problems. If you see the leaves falling off the plant, it's probably because the roots are not getting enough water.
Pruning is a critical part of maintaining a healthy birch tree. By pruning away dead or dying branches, you allow for new growth and help the tree to stay strong. Pruning also helps to control the shape of the tree, so that it doesnt become too wild. To prune your birch tree, start by removing any dead or dying branches. Cut these branches back to the point where they meet a healthy branch or the trunk of the tree. Next, trim away any branches that are growing in the wrong direction, or that are rubbing up against other branches. Finally, cut back any branches that are too long or that are growing out of control. Pruning your birch tree may seem like a lot of work, but its important to do it on a regular basis to keep the tree healthy and looking its best.
Propagation of birch trees (Betula utilis) is typically done by rooting stem cuttings taken from the desired tree. Cuttings should be taken from young, healthy trees in late spring or early summer. The cuttings should be about 6 inches long and should have at least 2 leaves. Before planting, the cuttings should be placed in a rooting hormone. The cuttings can then be planted in a well-drained potting mix. The pots should be kept in a shady location and the soil should be kept moist. It can take several months for the cuttings to rooted and establish. Once they are rooted, they can be transplanted to their permanent location.
Usually, the plant growth rate during the spring and summer months when the days are long and the temperatures are warm. The average growth rate for this species is about one foot per year. However, during the fall and winter months, the average growth rate decreases to about half a foot per year. The reason for this decrease is likely due to the shorter days and cooler temperatures during these months.
Common problems for this kind of plant are Japanese beetles, aphids, and scale. Japanese beetles are the most serious problem, as they can strip a tree of its leaves in a matter of days. Aphids and scale can also cause damage, but are not as destructive as Japanese beetles.
