Hoya thomsonii ‘Pink’ is a captivating houseplant known for its fuzzy, oval-shaped leaves and clusters of star-shaped pink blooms. These flowers emit a sweet, honey-like scent, making it a favored choice among plant enthusiasts.
Hoya Thomsonii Pink Care
Hoya thomsonii ‘Pink’ thrives in bright, indirect light, which encourages vibrant foliage and flower production. While it can tolerate gentle morning sun, avoid direct afternoon rays as they can scorch leaves. Position the plant near an east or west-facing window, or use a sheer curtain to diffuse intense light.
To prevent root rot, allow the top layer of the potting medium to dry out slightly, or even nearly completely, between waterings. Overwatering leads to yellowing leaves and foliage drop, while underwatering causes drooping or shriveled leaves. The plant’s thick, waxy leaves store water, similar to succulents, indicating its tolerance for drier conditions.
A well-draining, airy mix supports the plant’s epiphytic nature. Suitable blends often include orchid bark, perlite, and coco coir. This substrate allows roots to breathe and mimics the plant’s natural growing conditions where it attaches to trees or rocks.
Hoya thomsonii ‘Pink’ prefers temperatures between 15°C and 28°C (65-85°F). Protect it from cold drafts or temperatures below 10°C (50°F). Higher humidity, ideally 50% to 70%, is appreciated, especially in drier indoor environments. Grouping plants or using a humidifier can provide this.
Fertilize lightly every 4 to 6 weeks during spring and summer with a balanced liquid fertilizer. Avoid over-fertilizing, and reduce or cease feeding during cooler, dormant months. Repotting is infrequent, only necessary when the plant is root-bound or the potting medium has degraded.
Propagating Hoya Thomsonii Pink
Propagate Hoya thomsonii ‘Pink’ using stem cuttings during spring or summer. Select a healthy stem section, 10 to 15 centimeters long, with at least one node. Make a clean cut just below a node using sterilized scissors or pruning shears.
Remove leaves from the bottom to expose nodes, as submerged leaves can rot. Optionally, allow the cut end to callous for a few hours to a day to prevent rot, especially when rooting in soil. Rooting can occur in water, sphagnum moss, or a well-draining soil mix (e.g., perlite and coco-peat).
Provide warm, humid conditions for cuttings. Placing them in a location with consistent temperatures and high humidity, or creating a mini-greenhouse effect with a plastic bag, encourages root development. Once roots are established (5 to 7 centimeters long), transfer the cutting to a small pot with a suitable, well-draining potting mix.
Common Problems with Hoya Thomsonii Pink
Lack of blooms is a common concern, often due to insufficient light; the plant needs bright, indirect conditions to flower reliably. Plant maturity also plays a role, with younger specimens sometimes taking a year or two to bloom. Manipulating day length by providing shorter light periods, especially as autumn approaches, can encourage flower bud formation.
Yellowing or dropping leaves signal care imbalances. Overwatering often causes mushy, soft, uniformly yellowing leaves, sometimes with root rot. Underwatering may cause individual leaves to yellow, shrivel, and feel dry. Sudden environmental shifts or nutrient deficiencies can also contribute to leaf discoloration, with lower leaves yellowing if nutrients are lacking.
Pest infestations are a potential problem. Common sap-sucking pests like mealybugs, spider mites, and scale insects can affect Hoya thomsonii ‘Pink’. Identify them by their appearance or sticky residue. Regular inspection helps early detection and prompt treatment with appropriate horticultural solutions.
Fungal problems, such as root rot and leaf spot, can arise from improper environmental conditions. Root rot results from consistently wet soil due to overwatering or inadequate drainage. Leaf spot, characterized by dark spots, is exacerbated by excess water on foliage, high humidity, or poor air circulation. Addressing these factors and ensuring good airflow helps prevent fungal development.
