Pruning for Eriogonum tiehmii Reveal
Eriogonum tiehmii Reveal has an appealing, bushy growth habit that does not require pruning to maintain attractiveness. However, removing spent flower heads can encourage additional blooms. Here are some useful tips to remember:
- Remove the flower stalks as soon as they begin to fade in the late summer or early fall.
- Leave healthy foliage intact until winter arrives to continue using the leaves for photosynthesis.
- Maintain a tidy appearance by removing any dead or diseased foliage throughout the year.
Propagation of Eriogonum tiehmii Reveal
Eriogonum tiehmii Reveal can be propagated through both seed and vegetative means. However, seed propagation is the most common and easiest method for growing this plant.
Seed propagation
Seeds of Eriogonum tiehmii Reveal can be collected from mature plants in late summer or early fall. The seeds should be stored in a cool, dry place until ready for planting.
To sow the seeds, prepare a well-draining potting mix and fill a propagation tray or container with it. Then, scatter the seeds on top of the mix and lightly cover them with a thin layer of the mix. Water the tray sufficiently to make sure that the seeds remain moist during the germination process.
Place the propagation tray in a warm, well-lit area like a greenhouse or bright window sill. Germination may take anywhere from one to three weeks depending on temperature and moisture levels.
After the plants have emerged and developed their first set of true leaves, they can be transplanted into individual pots or directly into the ground.
Vegetative propagation
Eriogonum tiehmii Reveal can also be propagated through vegetative means such as stem cuttings or division of established plants.
To propagate through stem cuttings, take a cutting from a healthy and mature plant in spring or summer. The cutting should be about 4-6 inches long and include at least one node. Remove the lower leaves from the cutting, dip the cut end in rooting hormone, and plant it in a well-draining potting mix. Keep the cutting warm and moist until roots form, then transplant it into its final location.
Division of established plants is another method of vegetative propagation. This method involves carefully digging up an established plant and dividing the rootball into sections. Each section should have several stems and a good amount of roots. Replant the divided sections in well-draining soil and water thoroughly.
