How to propagate mums or chrysanthemums?

 

Mums, also known as chrysanthemums, can be propagated through several methods, including division, stem cuttings, and root cuttings. Here's a step-by-step guide on how to propagate mums using division and stem cuttings:

1. Division:

   • Choose a healthy mum plant that has been growing for at least a year. The best time to divide mums is in early spring or early fall.
   • Carefully dig up the mum plant, trying to preserve as much of the root system as possible.
   • Gently separate the clump into smaller sections by pulling them apart or using a clean, sharp knife or garden tool. Each section should have its own set of roots and shoots.
   • Trim any damaged or rotting roots, and cut back the foliage to reduce stress on the divided plants.
   • Replant each divided section in a prepared garden bed or individual pots, ensuring the roots are properly placed and covered with soil. Space the divisions appropriately, leaving enough room for their mature size.
   • Water the newly planted divisions thoroughly and provide regular watering as needed until they become established.

2. Stem Cuttings:

   • Select a healthy mum plant with strong stems and vibrant foliage.
   • Take stem cuttings in spring or early summer when the plant is actively growing. Cut 3-4 inch (7-10 cm) sections from the tips of healthy stems, making clean cuts just below a leaf node.
   • Remove the lower leaves from the cuttings, leaving a few sets of leaves at the top.
   • Dip the cut ends of the stems in a rooting hormone powder or gel to promote root development (optional).
   • Insert the cuttings into a well-draining potting mix or rooting medium. You can use a tray, small pots, or a propagation tray with individual cells.
   • Mist the cuttings with water and cover the tray or pots with a clear plastic bag or a plastic dome to create a humid environment.
   • Place the cuttings in a warm location with bright, indirect light. Avoid direct sunlight as it may cause excessive heat and drying out.
   • Check the moisture level of the rooting medium regularly and mist the cuttings as needed to maintain humidity.
   • After a few weeks, gently tug on the cuttings to check for resistance, indicating the presence of roots.
   • Once rooted, transplant the rooted cuttings into individual pots or a prepared garden bed. Continue to care for them by providing adequate water, sunlight, and nutrients.

Remember to provide the newly propagated mums with appropriate care, including regular watering, well-draining soil, and adequate sunlight. With proper attention, the propagated mums should establish themselves and grow into healthy plants, ready to bloom in their next season.
