In its natural habitat, it grows under the canopy of trees, where the sunlight is filtered and not direct. Therefore, it is best to grow this plant in partial to full shade. Direct sunlight may harm the plant, causing sunburn and leaf scorching.
Temperature Requirements
The optimal temperature for the growth of Oxyrhachis gracillima (Baker) C.E.Hubb. subsp. occidentalis Gledhill ranges between 18 to 25°C (64.4 to 77°F). The plant can tolerate some variations in temperature, but extreme heat or cold may affect its growth. Therefore, it is best to maintain the plant at room temperature or slightly cooler.
Soil Requirements
Oxyrhachis gracillima (Baker) C.E.Hubb. subsp. occidentalis Gledhill prefers well-draining and slightly acidic soil. The soil should have good moisture retention capacity, but not waterlogged. Ideal soil mixture for this plant includes a balanced mix of peat moss, perlite, vermiculite, and sand. The pH level should be between 5.5 to 6.5. Avoid using heavy clay soils or soils that are alkaline in nature.
Cultivation Methods for Oxyrhachis Gracillima Subsp. Occidentalis
Oxyrhachis gracillima subsp. occidentalis can be grown in both pots and garden beds. For pot cultivation, use a container with good drainage holes, and for in-ground planting, choose a location with well-draining soil and that receives partial shade.
Watering Needs for Oxyrhachis Gracillima Subsp. Occidentalis
Water Oxyrhachis gracillima subsp. occidentalis at least once a week, especially during the hot and dry seasons. Ensure that the soil is moist but not waterlogged because excess water can lead to root rot.
Fertilization for Oxyrhachis Gracillima Subsp. Occidentalis
Apply a balanced, slow-release fertilizer to Oxyrhachis gracillima subsp. occidentalis every three months. Alternatively, top-dress the soil with compost annually in early spring to improve soil quality and fertility.
Pruning Oxyrhachis Gracillima Subsp. Occidentalis
To promote bushier and more compact growth, pinch off the top branches of Oxyrhachis gracillima subsp. occidentalis every spring. Additionally, remove any dead, diseased, or damaged branches promptly to prevent further damage to the plant.
Propagation of Oxyrhachis gracillima subsp. occidentalis
Oxyrhachis gracillima subsp. occidentalis can be propagated through seeds or stem cuttings.
Propagation through seeds
The seeds of Oxyrhachis gracillima subsp. occidentalis can be sown directly into well-drained potting mix. The potting mix should be moistened before sowing the seeds to ensure good seed-to-soil contact. The seeds should be placed on the surface of the potting mix and lightly covered with a thin layer of the mix. The container should be covered with plastic wrap or a clear plastic bag to retain moisture.
The seeds typically germinate within two to four weeks. Once the seedlings have emerged, the plastic wrap or bag should be removed to allow for ventilation. The container should be placed in a bright location, but out of direct sunlight.
Propagation through stem cuttings
The stem cuttings of Oxyrhachis gracillima subsp. occidentalis should be taken from healthy, mature plants. The cuttings should be taken during the growing season and should be approximately 10 cm in length. The bottom leaves should be removed, and the cutting should be dipped in rooting hormone.
The cuttings should be planted in well-drained potting mix and covered with plastic wrap or a clear plastic bag to retain moisture. The container should be placed in a bright location, but out of direct sunlight. The cuttings typically root within four to six weeks.
Once the cuttings have rooted, they can be transplanted into individual containers or directly into the garden.
