Pruning
Pruning is necessary to maintain the shape and size of Crataegus iracunda Beadle var. stolonifera (Sarg.) Kruschke and to promote healthy growth. It is best to prune the plant during the dormant season in late winter or early spring before new growth begins.
The main objective of pruning is to remove dead, damaged, or diseased wood and to thin out overcrowded branches. It is also essential to remove any suckers emerging from the base of the plant to prevent them from competing with the main stem.
Disinfecting pruning tools with a solution of alcohol or bleach before and after use can prevent the spread of diseases among the plants.
Propagation of Crataegus iracunda Beadle var. stolonifera (Sarg.) Kruschke
Crataegus iracunda Beadle var. stolonifera (Sarg.) Kruschke, commonly known as the Hooked Hawthorn, is a deciduous shrub native to North America. It produces attractive white flowers and red fruits that are relished by birds and other wildlife. The plant can be propagated using several methods, including seeds, cuttings, and layering.
Propagation by Seeds
Seeds are the most common method of propagating Crataegus iracunda var. stolonifera. The seeds should be collected from ripe fruits in the fall and sown immediately. If the seeds are not sown right away, they should be stored in a cool and dry location until ready to use. The seeds should be sown in a well-draining soil mix and kept moist until germination, which can take several weeks to several months. Seedlings should be transplanted to individual containers when they are large enough to handle and grown in a greenhouse or nursery until they are of a suitable size for transplanting.
Propagation by Cuttings
Cuttings are another method of propagating Crataegus iracunda var. stolonifera. Softwood cuttings should be taken in the early summer when the plant is actively growing. The cuttings should be about six inches long and taken from the current season's growth. They should be dipped in a rooting hormone and placed in a well-draining rooting mix. The cuttings should be kept moist and in a humid environment until roots have formed, which can take several weeks to several months. Once rooted, the cuttings should be transplanted to individual containers and grown until they are of a suitable size for transplanting outdoors.
Propagation by Layering
Layering is a method of propagation that involves bending a flexible stem down to touch the ground and covering it with soil. The stem should be wounded at the point where it will be covered with soil to encourage root development. Once the stem has rooted, it can be cut from the parent plant and transplanted to its new location. Layering is best done in the spring or fall when the plant is actively growing.
Disease and Pest Management for Crataegus iracunda Beadle var. stolonifera (Sarg.) Kruschke
