Propagation of Ruellia nudiflora var. glabrata
Ruellia nudiflora var. glabrata can be propagated through various methods such as seeds, stem cuttings, and division.
Propagation by Seeds:
The best time for collecting seeds of Ruellia nudiflora var. glabrata is during autumn. The collected seeds must be sown on well-drained soil at a depth of about ΒΌ inch. The soil should be kept moist, and the seedlings will appear within two to four weeks. Once the seedlings have grown to a height of about 2 inches, they must be transplanted to a pot or a well-prepared bed.
Propagation by Stem Cuttings:
The best season for taking stem cuttings of Ruellia nudiflora var. glabrata is early spring. Cut a stem of about 8 inches length from a mature plant. Remove all the leaves except the top two or three leaves. Place the cutting in a rooting hormone and then insert it into a well-draining soil mix. The soil should be kept moist and the cutting will root within 3-4 weeks. The propagated plant must be transplanted once it has grown to a height of about 4-6 inches.
Propagation by Division:
Ruellia nudiflora var. glabrata can be propagated by division either during early spring or early autumn. The clumps can be divided into smaller sections, and each section must have at least one stem with roots. Plant the divided sections in well-drained soil and keep the soil moist until the plant is established.
