It is important to read the label before application. Overfertilizing can lead to burnt or damaged foliage, so be sure to follow the instructions.
Pruning of Crataegus faxonii Sarg.
The best time to prune Crataegus faxonii Sarg. is early spring before bud break. Remove any dead, diseased, or damaged wood. Also, prune older wood to encourage new growth and better form. Do not remove more than a third of the plant at once. Light pruning after blooming during midsummer can promote a second flush of flowers.
Propagation of Crataegus faxonii Sarg.
Crataegus faxonii Sarg., commonly known as Faxon hawthorn, is a shrub or small tree that belongs to the Rosaceae family and is native to North America. It is an attractive plant used for ornamental purposes as well as for its medicinal properties. The plant has sharp thorns and produces white flowers in the spring, followed by red berries in the fall.
Propagation Methods
There are several methods through which Crataegus faxonii Sarg. can be propagated. These include:
Seeds
Seeds are the most common method of propagating Crataegus faxonii Sarg. The seeds are usually collected from the fruit in fall, cleaned, and stored until the following spring. They should be planted in a well-draining soil mix in a location with full sun. Germination typically occurs within 2-3 weeks, and the seedlings should be fertilized and watered regularly until they are large enough to be transplanted.
Cuttings
Another method of propagating Crataegus faxonii Sarg. is through cuttings. Semi-hardwood cuttings, taken in the late summer or early fall, are usually used for this purpose. The cuttings should be planted into a rooting hormone mix and placed in a greenhouse or in a shaded location. They should be watered regularly and monitored for signs of new growth. The Cuttings are usually ready for transplantation after a year.
Grafting
Grafting is a more advanced method of propagation and is usually performed by horticulturists. Scionwood, taken in the winter, is grafted onto rootstock of a similar species of Crataegus. The grafted plants are then grown in ideal conditions until they are mature enough to be transplanted, usually several years.
Propagation of Crataegus faxonii Sarg. can be performed through seeds, cuttings, and grafting methods, depending on the skill level of the propagator and the desired number of progeny. With the proper care and attention, the cuttings and seeds of Crataegus faxonii Sarg. can produce healthy, robust young plants.
Disease Management for Crataegus Faxonii Sarg.
Crataegus faxonii Sarg. is a deciduous shrub or small tree that is susceptible to various fungal and bacterial diseases, which can cause different types of problems, such as leaf spots or blight, cankers, powdery mildew, and rust. A good disease management program begins with prevention, through proper care and cultural practices that promote plant health, including regular irrigation, fertilization, and pruning, to remove diseased or dead plant tissue, and improve air circulation and sunlight penetration. Chemical control may be necessary in severe cases or when preventative measures fail.
Leaf spot diseases are common in hawthorns, and they are caused by several fungal species, such as Phyllosticta spp., Entomosporium spp., and Diplocarpon spp. They typically produce small, circular to angular, dark brown or purple spots on leaves, which may coalesce and cause defoliation. To manage leaf spot, use resistant cultivars, avoid overhead irrigation, and apply fungicides containing chlorothalonil or copper-based compounds at regular intervals during the growing season.
Blight is another fungal disease that affects hawthorns, usually in wet or humid conditions. It can cause dieback of young shoots and leaves, as well as cankers and sunken lesions on twigs and branches. To manage blight, prune affected parts, keep the soil well-drained, and apply fungicides containing azoxystrobin or propiconazole during bud swell and bloom stages.
Powdery mildew is a fungal disease that causes a white to gray powdery coating on leaves, stems, and flowers, weakening the plant and reducing its aesthetic value. It is most severe in dry, warm conditions, and can be managed by avoiding overcrowding, improving air circulation, and using fungicides containing myclobutanil or propiconazole at 7-14 days intervals.
Rust is a fungal disease that produces orange-red pustules on leaves and stems, and can cause severe defoliation, especially in wet springs. To manage rust, remove fallen leaves, use resistant cultivars, and apply fungicides containing chlorothalonil or triadimefon before and after flowering.
Pest Management for Crataegus Faxonii Sarg.
Crataegus faxonii Sarg. is generally not a target for major pests, but it can be infested by several insect species, such as aphids, scale insects, borers, and leafminers, which can damage leaves, twigs, and fruits. A good pest management program begins with monitoring, identification, and prevention, through regular visual inspection, trapping, and cultural practices, such as pruning, mulching, and fertilizing. Chemical control may be necessary in severe cases or when preventative measures fail.
Aphids are small, soft-bodied insects that feed on sap from leaves and stems, and excrete a sticky honeydew that can attract ants and promote fungal growth. They can be controlled by using insecticidal soap or neem oil, which disrupt their feeding and reproduction.
Scale insects are small, flat, and oval or round insects that attach themselves to leaves and bark, and suck sap from the plant. They can cause yellowing, curling, or wilting of leaves, and can be controlled by using horticultural oil or pesticides containing insect growth regulators or systemic compounds.
Borers are the larvae of beetles and moths that tunnel into the bark and wood of the tree, causing dieback, girdling, or death. They can be prevented by keeping the plant healthy, removing infested wood, and applying insecticides containing carbaryl or bifenthrin at the base of the trunk and major branches.
Leafminers are small larvae that feed inside the leaves, creating serpentine or blotchy mines that can reduce the photosynthetic capacity of the plant. They can be controlled by removing infested leaves, using insecticidal soap or spinosad, and enhancing the natural enemies of the pest, such as parasitic wasps and lacewings.
