About soil condition, Hardy evergreen shrubs can grow in a wide variety of soil conditions as long as the soil is well-drained. They are tolerant of both dry and wet soils, and can even grow in heavy clay soils. However, they will not tolerate soils that are consistently soggy or waterlogged.
So, like the other plants, evergreen shrubs need sunlight to grow. However, these hardy plants can tolerate less sunlight than most other types of plants. In fact, evergreen shrubs can do well in shady areas where other plants would struggle. If you're looking for a low-maintenance plant that can thrive in a range of lighting conditions, an evergreen shrub is a good option.
The temperature condition is one of the most important factors to consider when choosing hardy evergreen shrubs. Some shrubs are more tolerant of cold weather than others, so it is important to know what the minimum temperature is for the shrub you are considering. If the temperature gets too cold, the shrub will not be able to survive.
Ideal humidity condition for this plant is 60% to 70%. Hardy evergreen shrubs can tolerate a wide range of humidity conditions, but they will thrive best in an environment that is not too dry or too wet. If the air is too dry, the leaves of the plant will begin to turn brown and drop off. If the air is too wet, the leaves of the plant will begin to rot.
Mentioning fertilizer, this kind of plant needs plenty of organic matter in order to maintain good growth. Incorporate some type of fertilizer when planting and continued throughout the growing season. Look for a fertilizer that has a low nitrogen content and is higher in phosphorus and potassium. As for the roots, they like to stay on the moist side but not too wet. Amend the soil with organic matter to help with drainage and to keep the roots cooler in the summer. Hardy evergreen shrubs are pretty versatile when it comes to soil but prefer a well-drained soil.
Pruning is an important part of caring for hardy evergreen shrubs. By pruning, you can encourage new growth, remove damaged or diseased branches, and control the shape and size of the shrub. Evergreen shrubs can be pruned in late winter or early spring, before new growth begins. When pruning, be sure to use sharp, clean pruning shears. Make sure to make cuts at a 45-degree angle, just above a bud or branch.
Propagation is best done by taking semi-ripe cuttings in late summer. Take the cuttings from new growth at the tips of the stems. Cut just below a leaf node with a sharp knife or pruning shears. The cutting should be 4-6 inches long.Remove the lower leaves from the cutting, and dip the cut end in rooting hormone. Stick the cutting in a pot filled with moistened perlite, vermiculite, or sand. Cover the pot with a clear plastic bag, and place it in a bright, warm location out of direct sunlight. Keep the soil moist, but not soggy, and in 4-8 weeks the cutting should have rooted and will be ready to transplant.
Usually, the plant growth rate is relatively slow. However, there are a few varieties that grow at a medium to fast rate. When choosing a shrub, it is important to consider the adult size of the plant and how long it will take to reach that size.
Common problems for this kind of plant are pests and diseases. Pests include aphids, scale insects, and whitefly. These pests can be controlled with insecticidal soap or horticultural oil. Diseases include root rot, stem rot, and leaf spot. These diseases can be controlled with fungicides.
