Cultivation Methods
Oxalis gracilis Jacq. var. lilacea T.M.Salter is a relatively easy plant to grow and care for. It thrives in well-draining soil, and a location that receives partial shade is ideal. However, it can also grow in full sun as long as it's not too hot.
When planting, ensure that the soil is well-drained, and if necessary, amend it with organic matter. Plant the bulbs about 2-3 inches deep and space them about 6 inches apart.
Watering Needs
It's important to keep the soil consistently moist during the growing season, but not overly wet. Overwatering can cause the bulbs to rot, so ensure that the soil is well-drained and not waterlogged.
During the dormant season, reduce watering but do not allow the soil to dry completely.
Fertilization
Oxalis gracilis Jacq. var. lilacea T.M.Salter benefits from regular fertilization during the growing season. Use a balanced fertilizer every 2-4 weeks throughout the growing period.
Be careful not to over-fertilize, as this can lead to excessive leaf growth at the expense of flower production.
Pruning
Pruning is not necessary, but removing the spent flowers can encourage continued blooming. If the plant becomes too leggy or overgrown, it can be cut back to the ground to encourage new growth and rejuvenation.
Propagation of Oxalis Gracilis Jacq. var. Lilacea T.M.Salter
Oxalis gracilis Jacq. var. lilacea T.M.Salter, commonly known as pink woodsorrel or slender yellow woodsorrel, is a low-growing, perennial plant that belongs to the family Oxalidaceae. It is native to the southwestern United States and Mexico and is widely grown as an ornamental plant because of its attractive foliage and pink flowers. Propagation of this plant is relatively easy, and it can be propagated by three methods: seeds, cuttings, and division.
Propagation by Seeds
Propagation of Oxalis gracilis Jacq. var. lilacea T.M.Salter using seeds is a simple process. The seeds are formed in small, round capsules that are produced after the flowers fade. To propagate the plant using seeds, collect the capsules when they turn brown and split open. Take the seeds out and sow them directly on the soil in a pot or garden bed. The best time to sow the seeds is in the spring or early summer. The seeds usually take about two to three weeks to germinate. Keep the soil moist, but not too wet, during this period.
Propagation by Cuttings
Oxalis gracilis Jacq. var. lilacea T.M.Salter can also be propagated by stem cuttings. To propagate the plant using cuttings, take stem cuttings that are about 5-6 inches long. Remove the leaves from the bottom and dip the end of the cutting into rooting hormone. Plant the cutting in moist, well-drained soil and keep it in a warm, humid place. The cutting will root in about two to three weeks. Once it is rooted, you can transplant it to a pot or garden bed.
Propagation by Division
Propagation of Oxalis gracilis Jacq. var. lilacea T.M.Salter can also be done by division. To propagate the plant using this method, dig up the entire plant and carefully separate the clumps using a sharp, clean knife. Each division should have several healthy stems and roots. Replant the divisions immediately in a new pot or garden bed. Water them well and keep them moist until they become established.
Overall, propagating Oxalis gracilis Jacq. var. lilacea T.M.Salter is a relatively easy process that can be done by anyone with basic gardening skills. Whether you use seeds, cuttings, or division, you can have new plants in no time.
