Considered very low-maintenance and especially hard to kill, this is a perfect plant for those who do not believe themselves to have a green thumb.
Hoya Publicalyx Soil
Having the right growing medium is essential to keep your Hoya in optimum health. A well-draining soil, rich in organic material that is water retentive but not prone to becoming waterlogged, is ideal. To create a perfect growing medium, combine peat or coco coir to perlite and orchid bark in equal parts.
Hoya Publicalyx Fertilizer
During the warm growing spring and summer season, your Hoya will appreciate regular feeding from a balanced liquid fertilizer that is high in potassium. Ensure that you follow all label instructions and do not overfertilize. This plant should not be fertilized during fall and winter. Foliar applications of fertilizer have been indicated to encourage flowering.
Hoya Publicalyx Watering
Like many other houseplants, it is important not to overwater this Hoya, as it may lead to root rot. This plant should be allowed to dry out around 1-2 inches before rewatering. When rewatering, it is good to give this Hoya a thorough soak. Depending on growing conditions, Hoya Publicalyx will likely need to be watered around twice a week during the growing season and around once a week during fall and winter cooler months.
Hoya Publicalyx Light Requirements
To give the best Hoya Publicalyx care, grow it in a lot of bright indirect light. At least six to seven hours daily is recommended. In its natural environment, this plant is accustomed to growing around and under other plants, thereby receiving dappled sunlight. It is best to try to emulate these conditions in the home. Without sufficient light, these Hoyas will considerably slow down their growth. However, too much direct, intense sunlight will cause leaf scorching.
Hoya Publicalyx Temperature & Humidity
Being a tropical plant, Hoya Publicalyx likes to remain warm, around 65 – 85 degrees Fahrenheit at all times. Therefore, do not place your Hoya near anything that will cause an intense fluctuation of temperatures, such as a heater, cold window, AC unit, or near drafts. In addition, this Hoya likes to be kept in an area with at least 60% humidity, which is above the average humidity level of a typical household. Therefore, it is recommended that you install a humidity tray, humidifier or mist the leaves of your Hoya frequently to keep humidity levels high.
Repotting Hoya Publicalyx
As this Hoya likes to remain relatively rootbound, it may not need to be repotted for up to five years or even longer. If the soil is draining well and your Hoya appears healthy, you will not need to repot it. When the time for repotting does come, ensure that you only move up to a container that is 1-2 inches larger in diameter than the previous pot and ensure it has drainage holes.
Hoya Publicalyx Maintenance & Pruning
Pruning of Hoya Publicalyx is not necessary to maintain the health of the plant. However, in spring you may remove dead, discolored, or unwanted stems using sterilized pruning shears.
Hoya Publicalyx Propagation
Propagation of Hoya Publicalyx is straightforward and may be done through either stem cuttings, leaf cuttings, or from seed. Propagation by seed is the easiest but requires a significantly longer period of time to get a healthy new plant. To take a stem cutting, use a sterilized blade to cut a 6-7 inch piece of stem from the end of the stalk at a node during active growth. Allow the cutting to callus and remove lower leaves from the stem, leaving a few leaves at the top of the end of the cutting. Plant your cutting in a container with fresh soil and ensure that nodes are buried up to a couple inches. Water thoroughly and place in indirect light. Alternatively, you may take a leaf and plant the stem about 1.5 inches in the soil, and within two months, new plants should sprout from the base of the leaf.
