Propagation of Pyrola bracteata Hook. var. hillii J.K. Henry
Pyrola bracteata Hook. var. hillii J.K. Henry, commonly known as Hill's wintergreen, is a native North American plant species belonging to the Ericaceae family. Propagation of this plant can be achieved through both sexual and asexual methods.
Sexual propagation
Pyrola bracteata Hook. var. hillii J.K. Henry propagates via seed germination. The best time to collect the seeds is during the autumn months after the fruit has matured. The seeds should be sown in a well-draining, moist, and rich soil mix. The soil acidity level should be within the range of 4.5-6.5 pH for optimal growth. After sowing, the seeds should be covered with a thin layer of soil and kept consistently moist and warm in a shaded area. Germination may take weeks to a few months, and once germinated the seedlings can be transplanted to their final location once they've grown to an appropriate size.
Asexual propagation
Vegetative propagation can be carried out through division and cuttings. One of the easiest ways to propagate Pyrola bracteata Hook. var. hillii J.K. Henry is by division. This method involves separating the roots and then replanting them. The time of division is crucial for the success of the propagation. It's best to carry out division during the spring or autumn months while the plant is still dormant. The separated plant parts should be replanted into a well-draining, moist, and rich soil mix.
Cuttings can also be taken during spring and summer. The cuttings can be around four inches in length and should be taken from the plant's side shoots. Dip the cut ends into rooting hormone before planting them in well-draining, moist soil in a shaded area. To increase the success rate of cuttings, keep the relative humidity high by covering the cutting with a plastic bag or container, providing a humid environment for the developing roots to grow. Once the cuttings are established, they can be transplanted to their final growing location.
