How to care for Magonia holly

Plant care is minimal. In the spring, you will need top dressing, for this, azofoska is suitable, for 1 m² you will need from 95 to 120 g of the substance. In the summer, additional watering will be required, but only if there is no rain. Add 10 liters of water under one bush. The optimal interval between soil moisture is two weeks. Then the bush will thank you with its spectacular appearance. In addition to introducing water under the roots, you can moisten the leaves of the plant, for this use hose irrigation. Another important point of care is the timely loosening of the soil so that the rhizomes receive a sufficient amount of air.

If you need to transplant an evergreen beauty, it is better to perform this process in the summer.

Despite the fact that some sources write about the frost resistance of the plant, in our conditions it is better to cover it for the winter, using spruce branches for this. Try to follow this rule at least for young plants that are less than 5 years old.

Powdery mildew can form on the shrub if it is improperly taken care of. Also, gardeners are often faced with the problem of root rot, rust. To combat these diseases, fungicides are used.

Shrub pruning

Mahonia is quite tolerant of pruning and can even be cut all the way down to the ground if you want to give the bush new growth. But usually it doesn't need a lot of pruning. Pruning should be done in the spring when the bush has bloomed.

To maintain the shape of the crown of Magonia, prune it at the end of autumn, remove a smaller part of the total length of the branches. Older shrubs are often pruned “under the stump” in order to return the shrub to its former decorative shape.

Pests and diseases

Mahonia can usually suffer from rust and powdery mildew, but these fungi are easy to spot and can be easily treated with a garden fungicide at the first sign of infection.

On this plant, you can find signs of pests such as whiteflies, aphids, or scale insects. All of these insects can leave sticky dew that can lead to mold growth.

Preparing a place for planting young bushes

The place for the growth and development of Mahonia plays a significant role. This culture does not tolerate too sunny areas, direct sunlight can easily burn the plant, this can be easily seen on the foliage. The crop grows best in shaded areas.
