About soil condition, cotoneaster prefers well-drained, somewhat dry soil, but will also grow in average, slightly moist soil. It is tolerant of poor soil, but not of wet soil. It will not grow in shade.
So, like the other cotoneaster trees, cotoneaster berries require full sun to partial sun in order to produce the best berries. If you have a cotoneaster tree that is not in an area that gets full sun, you may not get as many berries as you would like. The amount of sun that your cotoneaster tree gets will also affect the size of the berries.
The temperature condition that is most favorable for the growth of cotoneaster berries is a warm temperature. The plant grows best in warm weather and can tolerate some cold weather. However, if the temperature gets too cold, the plant will not produce as many berries.
Ideal humidity condition for this plant is around 50%. If the humidity is too low, the leaves will start to turn brown and drop off. If the humidity is too high, the leaves will start to yellow and drop off.
For the fertilizer, this family of plant usually requires a lot of organic matter in the soil to keep the roots healthy. The roots are very sensitive to the chemicals in the soil and can be easily damaged. A good rule of thumb is to use a fertilizer with a low nitrogen content.
Pruning cotoneaster is important to prevent the plant from getting too large. It is also important to remove any dead or diseased branches. When pruning, be sure to cut back to a healthy bud or branch.
Propagation of cotoneaster is typically done through rooting of soft wood cuttings taken from the plant in late spring or early summer. The cuttings should be about 4-6 inches long and should be taken from new growth that is just beginning to harden off. After taking the cuttings, strip off the leaves from the bottom half of the cutting and dip the cut end into a rooting hormone. Plant the cuttings in a potting mix designed for starting cuttings and water well. Place the pot in a warm, bright location out of direct sunlight and keep the soil moist but not soggy. Rooting should occur in 4-6 weeks. Once the roots are established, the new plants can be transplanted into their permanent location.
Usually, the plant growth rate is quite fast. They can add 2 to 3 feet of growth each year and will often live for 20 to 30 years. The berries on a cotoneaster plant are typically a deep red, but can also be pink, orange, or yellow. These berries are not only beautiful, but they are also a great food source for birds.
Common problems for this kind of plant are that the leaves may turn yellow and fall off the plant. Also, the plant may not produce as many berries as it should. If you notice any of these problems, you should consult with a plant expert to determine the cause and find a solution.
