How To Propagate Physostegia
Physostegia, also known as the “obedient plant, can be propagated through several methods, such as division, stem cuttings, and seed propagation. Here are the steps to propagate Physostegia through division and stem cuttings:
Propagation By Division:
- Wait until the plant has finished flowering and has gone dormant for the season.
- Dig up the entire plant using a garden fork or shovel.
- Carefully separate the clump into several smaller sections, making sure each section has roots and at least one growing point or shoot.
- Replant the divisions in well-draining soil in a new location, making sure they are watered well.
Propagation By Stem Cuttings:
- Choose a healthy, mature plant and cut a 4-6-inch stem from it.
- Strip the leaves from the bottom half of the stem and dip the cut end into rooting hormone.
- Place the stem cutting into a container filled with a moist, soilless potting mix.
- To produce a humid climate, wrap the container in plastic wrap or a clear plastic bag.
- Keep the cutting in bright, indirect light and keep the soil moist.
- After a few weeks, the cutting should begin to produce new growth, indicating that it has rooted successfully. At this point, you can transplant it into a larger pot or outside in a well-prepared garden bed.
Propagation by Seed:
- Wait until the plant has finished flowering and the seed heads have turned brown.
- Cut the seed heads off the plant and collect the seeds.
- Before you plant them, keep the seeds in a cool, dry place.
- In the spring, sow the seeds in a well-prepared garden bed or in small containers filled with a soilless potting mix.
- The seeds should be kept moist and covered with a thin layer of soil.
- Once the seedlings have grown large enough to handle, transplant them into their final location in the garden bed.
Regardless of the propagation method you choose, make sure to keep the newly propagated plants well-watered and protected from extreme temperatures until they are established. With proper care, your Physostegia plants should grow into healthy, beautiful additions to your garden.
