- Bolt cutters
Cotoneaster grows best in full sun, but can also tolerate partial shade. It can handle difficult circumstances, including poor soil. To get the best results, plant a cotoneaster shrub in moderately fertile, well-drained soil. They are adaptable to any kind of soil from sandy to clay, as long as it is not too wet.
Cotoneasters planted in the full sun develop dense branches, deep green foliage, and a lot of flowers and berries. Although this plant won’t be that good when planted in partial shade, it will still be able to produce flowers and fruits.
Follow the steps below to learn how you should plant a cotoneaster shrub.
- Buy a container-grown cotoneaster shrub from a well-known nursery
- Choose a spot carefully where you will like to keep the plant since cotoneasters do not transplant easily. Plant ground cover plants 5 feet apart, and keep a space of 4 to 6 feet while planting larger plants.
- Dig a hole which is twice as deep and wide as the plant’s root ball.
- Eliminate wire from the root ball if present with bolt cutters and use garden scissors to get rid of protective burlap.
- Get rid of densely matted roots before placing the cotoneaster shrub in the hole. Also, the top of the root ball must be at ground level. If you are planting a cotoneaster shrub near your house, turn it around so that it can face outside.
- Backfill the hole with some topsoil after you amend it with peat moss or compost.
- Apply a thick layer of bark mulch or wood chips soon after you plant cotoneaster, to preserve soil moisture and for keeping the weeds away.
Propagating cotoneaster plants
Cotoneaster plants can be propagated with softwood cuttings in the month of summer. It is a plant that can be easily multiplied by preparing cuttings. Although preparing cuttings is a little hard, it is still one of the best ways to propagate this shrub. Before starting this, get hold of rooting hormones since it will enhance your opportunities for success.
Birds are the biggest propagators of cotoneaster plants since they spread the seeds of the berries they have eaten. Once the berries become soft and mushy, the birds will no longer eat them and it will ultimately fall to the ground where they will start growing. These seedlings can be transplanted easily once they have grown a foot tall.
Pruning and caring for Cotoneaster Plants
It is very easy to take care of cotoneaster plants as its requirements are very limited. Regular pruning helps keeps the cotoneaster plants dense, assures beautiful flowers, and thick foliage. Mainly, cotoneasters require light pruning to get rid of wayward branches or to control any disease. While pruning cotoneaster plants, only cut out selected branches to the base rather than re-shaping or shortening them.
Evergreen cotoneasters should be pruned in the month of spring so that you can shape and balance the shrub as per your preferences. Deciduous cotoneasters must be pruned during the fall to remove dead leaves and berries. Ground cover kinds of cotoneasters must be pruned only to remove dead and damaged branches. You can prune the low growing shrubs by removing some of the oldest branches in the month of spring. Medium and tall-growing cotoneaster plants look perfect when they are left un-pruned since in this way they can maintain their natural shape.
Watering Cotoneaster Plants
It is important to water cotoneasters frequently during the first season so that it can develop extensive, deep roots. Cotoneaster only needs water in case of strong heat. Hence, it is advised to water cotoneaster plants during the month of summer, particularly when it’s been days since the last rainfall. Potted cotoneaster requires a lot of water, and so you should water these plants as soon as you see that the surface soil has dried off.
Diseases and parasites that affect cotoneaster plants, and how to fight them
Cotoneasters plants are quite resistant in the face of several diseases, but can, unfortunately, fall victim to fire blight. If the fire blight is a contagious disease, and if it happens to a cotoneaster plant then its chances of survival will be very low. These plants are also prone to attacks from parasites aphids and scale insects.
Use fungicides to control diseases like fire blight. Spray plants with dormant oil and lime sulfur to eliminate scale insects. You can also slow the spread of scale insects or mealybugs with a powerful blast of water. It is advised to plant aphid-trapping plants like nasturtiums or aphid repellents like French marigold to naturally regulate aphid populations.
Cotoneaster is a very attractive plant and is particularly acknowledged for its berries. Maintenance of cotoneaster plants, from planting to pruning is very easy. So what are you waiting for? Follow the steps above and plant a cotoneaster plant soon!
