Propagation of Crataegus irrasa Sarg.
Crataegus irrasa Sarg., commonly known as the Parsley-leaved hawthorn, can be propagated by several methods:
Seed Propagation
Seeds of Crataegus irrasa Sarg. can be obtained from ripe fruits. The seeds should be sown immediately after collection, as they do not retain viability for long periods. The seeds should be soaked in water for 24 hours before sowing to enhance germination. A well-draining potting mix should be used, and the seeds should be sown at a depth of 2-3 times their size. Germination usually occurs within 2-3 months. Seed propagation is the easiest and most common method of propagating Crataegus irrasa.
Cuttings Propagation
Crataegus irrasa Sarg. can also be propagated by softwood or hardwood cuttings. Softwood cuttings should be taken during the growing season, while hardwood cuttings should be taken during the dormant season. The cuttings should be about 6-8 inches long, with a few leaves attached at the top. The base of the cuttings should be treated with rooting hormone, and then inserted into a well-drained potting mix. Place the pot in bright, indirect light and spray the cuttings with water regularly. Roots should develop within 3-6 weeks for softwood cuttings and within six months for hardwood cuttings.
Grafting Method
Grafting is a process that involves combining the tissue from two or more plants to create a new plant. Crataegus irrasa Sarg. can be propagated by grafting onto a compatible rootstock. The preferred time for grafting is in the early spring before new growth begins. The graft should be made using a whip-and-tongue or cleft graft. The newly grafted plant should be placed in bright, indirect light, and protected from excessive heat and cold.
Overall, Crataegus irrasa Sarg. can be propagated by either seed, cutting or grafting methods. Careful attention should be paid to the type of propagation method used to ensure a successful outcome.
