Erigeron molle can be propagated through several methods including division, seed, and stem cuttings.
Propagation through Division
Propagation through division is an effective method of multiplying Erigeron molle plants. This involves dividing the clumps of the mature plant into smaller sections and planting them separately. Division should be done in the spring or fall, as these are the times when the plant is dormant. To carry out this method, follow these steps:
- Choose a mature, healthy plant and dig it up from the ground.
- Identify the separate clumps of the root system.
- Using a sharp and sterilized cutting tool, cut the separate clumps from the mother plant and make sure that each section has healthy roots attached.
- Plant each section in a separate pot or in the ground, ensuring that they are watered thoroughly.
- Maintain good watering and soil conditions and regular application of fertilizers for the plants to establish quickly.
Propagation through Seed
Seeds can be collected from mature Erigeron molle plants and sown directly into a pot or in the ground in the fall season. Sowing seeds is an easy process and involves the following steps:
- Collect seeds from mature Erigeron molle plant when the seedheads are dry and brown.
- Sow seeds in moist soil and cover them with a thin layer of fine soil.
- Water the soil gently and place the pot in a bright location that receives some partial sunlight.
- Germination typically occurs within several weeks in favorable conditions.
Propagation through Stem Cuttings
Stem cuttings are another method of propagating Erigeron molle plants. It is best to use stem cuttings in mid-spring when the plant is actively growing. Here is how to grow Erigeron molle through stem cuttings:
- Select straight, healthy stems of the plant and cut them from the base with a sharp and sterilized tool.
- Remove the bottom leaves from the stem and dip the cutting in rooting hormone powder.
- Insert the cutting into a pot filled with well-draining soil or a rooting medium, making sure that the leaves do not touch the soil/medium.
- Water lightly, cover the pot with a plastic bag, and place it in bright and partially shaded light.
- Roots should form in 2-3 weeks, after which the plant can be transplanted into individual pots and grown until they are strong enough to be planted in the garden.
Erigeron molle is an easy plant to propagate through a variety of methods. It is an ideal choice for those who love to experiment with plant propagation.
