Propagation of Crataegus disjuncta Sarg.
There are a few different propagation methods that can be used for Crataegus disjuncta Sarg.:
Seed Propagation
The most common method of propagation for Crataegus disjuncta Sarg. is through seed. The seeds are stratified in a cool, damp place for about three months before planting in containers or in nursery beds. Germination usually occurs within one to three months. It is important to note that not all seeds may germinate, and it may take a few tries to get a good yield.
Cuttings Propagation
Another propagation method for Crataegus disjuncta Sarg. is through softwood or semi-hardwood cuttings. Cuttings should be taken in the early summer when the new growth is still green. These cuttings can be rooted in hormone-treated medium under mist, and will usually root within two to four weeks. Before planting the cuttings, it is important to remove all the leaves except for the top two or three.
Grafting Propagation
Grafting is another propagation method that can be used for Crataegus disjuncta Sarg. In this method, a piece of stem with buds is taken from a desirable cultivar and grafted onto the rootstock of a related species. This method is generally used to reproduce specific cultivars, and is often used in apple orchards.
Whichever propagation method you choose to use for Crataegus disjuncta Sarg., it is important to ensure that the young plants are protected from cold temperatures and strong winds until they are well-established.
