What factors affect the flowering of wax plants? A summary in one article
Light
For potted wax plants (Hoya), in spring and autumn it is best to place them on an outdoor south-facing windowsill or near a south-facing window indoors, which keeps the leaves emerald green and glossy and produces good flowering. In summer, they need to be moved to a shaded spot to prevent direct strong light, otherwise the leaves easily turn yellow. If kept in a place with insufficient light for a long time, the leaf color becomes pale and the flowers are few and not vivid.
Fertilizer and water
During the growing season, in addition to watering according to the principle of "dry when dry, wet when wet," you also need to frequently spray water on the leaf surface. In summer, watering should be sufficient, and at the same time attention should be paid to increasing air humidity to promote robust growth. In the peak growing season, apply a dilute cake fertilizer water combining nitrogen and phosphorus once or twice a month. Suitable temperature: wax plants (Hoya) are not cold-tolerant; the suitable growing temperature is 15°C-25°C. In winter, the room temperature should be kept above 10°C. If it is below 5°C, it is prone to cold damage, causing leaf drop, and even the death of the entire plant.
Repotting
It is best to choose tall-footed pots. Young plants should be repotted once every spring, and mature plants can be repotted once every 1-2 years. For plants that already have flower buds and flowers in bloom, the pot must not be moved at will, otherwise it easily causes bud drop and flower drop.
Pruning
Young plants should be pinched early to encourage branching, and supports should be set up in time so they can climb and grow upward. When repotting, part of the old roots should be cut off. After the flowers fade, let them wither and drop naturally; do not cut off the flower stems, because most of the flower buds for the next year will still sprout at the same place. If they are cut off, it will affect the number of flowers the following year. This is precisely one of the main reasons many flower enthusiasts find that their wax plants (Hoya) do not bloom or bloom very little.
