Evergreen trees is one of the most popular trees to plant. Many people choose to plant them because they are low maintenance and provide year-round interest. They are also relatively easy to care for and can tolerate a wide range of growing conditions.

About soil condition, evergreen trees as a whole prefer slightly acidic soil, though some varieties will tolerate neutral or even slightly alkaline conditions. They also tend to do well in nutrient-rich soils, though too much nitrogen can actually lead to problems such as excessive growth of soft, weak foliage that is more susceptible to damage from wind and rain.
Not too different with other plants, evergreen trees need sunlight to produce food. They use sunlight to convert carbon dioxide and water into carbohydrates and oxygen in a process called photosynthesis. Evergreen trees generally have shallow root systems, so they dont compete well with other plants for sunlight.
The temperature condition is ideal for evergreen trees. They thrive in cool to moderate climates and can withstand extreme cold. Some species of evergreen trees are even known to survive in temperatures as low as -60 degrees Fahrenheit.
Ideal humidity condition for this plant is around 50%. If the humidity drops below 40%, the leaves will start to turn brown and fall off. If the humidity gets too high, the leaves will start to droop and the plant will become susceptible to fungal diseases.
Regarding fertilizer, this family of plant is not too demanding and will do well with a yearly addition of compost or slow-release fertilizer in the spring. Be sure to apply it to the root zone and not on the leaves.
Pruning evergreen trees is an important part of keeping them healthy and looking their best. Unfortunately, pruning is often overlooked or done improperly. This can lead to damage to the tree and an unsightly appearance. The best time to prune evergreen trees is in late winter or early spring, before new growth begins. This gives the tree time to heal before the stress of summer. When pruning, make sure to remove dead, diseased, or damaged branches first. Then, trim back any branches that are rubbing against each other or growing in an unwanted direction. Finally, cut back any branches that are overcrowding the center of the tree. Pruning evergreen trees may seem like a lot of work, but its worth it to keep them healthy and looking their best. With a little care, your evergreen trees will thrive for years to come.
Propagation is the process of creating new plants from a variety of sources: seeds, cuttings, and division. All evergreen trees can be propagated from seed, but some, like pines and firs, require a period of cold stratification in order to germinate. Cuttings from evergreen trees can be tricky, as they often do not root well. The best time to take cuttings is in late spring or early summer. Evergreen trees can also be propagated by division, which is best done in early spring or fall.
Usually, the plant growth rate is pretty slow. They might only grow about 6 inches a year. But, there are some evergreen trees that can grow up to 24 inches a year. The growth rate really depends on the tree species and the growing conditions.
Common problems for this kind of plant are needlecast, dieback, and needle drop. Needlecast is a disease that causes the needles of the tree to fall off, while dieback is a condition where the tips of the branches start to die. Needle drop is when the needles of the tree drop prematurely.
