About soil condition, Acer shrub needs slightly acidic, well-drained soil. They are not tolerant of wet or heavy soils. If the soil is too alkaline, it can lead to chlorosis, or yellowing of the leaves.
Not too different with other plants, an acer shrub needs sunlight to grow. Sunlight helps the plant to create food through photosynthesis. The plant uses the sunlight to convert water and carbon dioxide into energy that it uses to grow. Without sunlight, the plant will not be able to create food and will eventually die.
The temperature condition in the Acer Shrub is optimal for the growth of the plant. The soil should be kept moist but not too wet. The plant should be fertilized regularly and should be given plenty of sunlight.
Ideal humidity condition for this plant is around 40%. If the air is too dry, the leaves will start to curl and drop off. The plant will also become less drought tolerant. If the air is too wet, the leaves will start to rot.
About fertilizer, this kind of plant is not really demanding. However, a little fertilizer in early spring will give it a nice boost. Be sure to use a root stimulator when planting. This will help the plant to develop a strong, healthy root system.
Pruning your acer shrub is an important step in maintaining its health and appearance. Acer shrubs are generally low-maintenance, but they do require occasional pruning to remove dead or damaged branches. You should prune your acer shrub in early spring, before new growth begins. Use sharp, clean pruning shears to make clean cuts. Make sure to prune any branches that are crossing or rubbing together, as well as any that are dead or diseased.
Propagation is most commonly done by rooting stem cuttings taken from the parent plant. Cuttings are best taken from new growth in late spring or early summer when the plant is actively growing. The cuttings should be 4-6 inches long and should have at least 2-3 leaves. Cut just below a leaf node and remove the bottom leaves. Dip the cut end of the cutting in rooting hormone and plant in a well-drained potting mix. Water well and place in a bright, but sheltered spot outdoors. Keep the soil moist, but not wet and in 4-6 weeks the cutting should have rooted and be ready to transplant.
Usually, the plant growth rate is considered to be slow to moderate. This is largely due to the fact that they have a relatively shallow root system. When acer shrub growth rate is taken into account, however, they are actually quite fast-growing.
Common problems for this kind of plant are: Pest and Diseases: Pests such as aphids, mites, scale, and borers can attack acer shrubs. Diseases such as powdery mildew, leaf spot, and tar spot can also affect these plants. Environmental Problems: Acer shrubs can be affected by environmental problems such as drought, heat stress, and cold damage.
