About soil condition, the elder tree likes a warm and moist soil, but it is also able to tolerate a wide range of soil conditions. It prefers a soil with a high organic content, but it is also able to tolerate a wide range of soil conditions.
Similar to other trees, the elder tree requires sun in order to grow. However, it is not as picky as some other trees when it comes to sun exposure. The elder tree can tolerate partial shade, which makes it a good choice for locations that are not too sunny.
The temperature condition that is most conducive to the growth of elder trees is a warm climate. Elder trees thrive in warm weather and are able to tolerate cooler temperatures as well. However, they will not survive in cold climates. Elder trees need full sun exposure to grow and thrive. They will not do well in shady areas.
Ideal humidity condition for this plant is 50%-70%. When the humidity is lower than 50%, the plant may suffer from dehydration and when the humidity is more than 70%, the plant may suffer from too much moisture.
For the fertilizer, usually the plant can tell you what it needs. If the leaves are yellow, it probably needs more nitrogen. If the leaves are pale, it might need more phosphorus. And if the leaves are brown and crispy, it might need more potassium. As for the roots, they need space to grow. So, make sure to loosen up the soil around the tree every few years.
Pruning is an important part of keeping your elder tree healthy. Pruning helps to remove dead or dying branches, as well as branches that are rubbing against each other. It also helps to promote new growth and keep the tree looking its best. When pruning your elder tree, be sure to use sharp, clean pruning shears.
Propagation is typically done through seed, which germinates best when sown fresh in the fall. Start the seed in seed flats filled with a mix of sand, peat, and perlite. Sow the seed on the surface of the mix and press in lightly. Keep the flats in a bright location but out of direct sun, and water as needed to keep the mix moist but not wet. The seed will germinate in one to three months. Once the seedlings are large enough to handle, transplant them into individual pots filled with a rich potting mix. Water well and place the pots in a bright location but out of direct sun. Once the seedlings are established, they can be transplanted into the garden.
Usually, the plant growth rate is quite fast, with the average tree growing up to 2.5m in a single growing season. However, growth rate will vary based on a tree's specific location and growing conditions. For example, trees that are growing in more favorable conditions (i.e. with more sunlight and water) will typically grow faster than those in less favorable conditions. Additionally, the type of soil can also impact growth rate, with trees in sandier soils typically growing faster than those in heavier clay soils.
Common problems for this kind of plant are its shallow roots, which are easily damaged or uprooted by strong winds. Other problems include: fungal diseases such as leaf spot and powdery mildew, canker, root rot, and Verticillium wilt. Insect pests include: aphids, scales, whiteflies, and caterpillars.
