Overview

The hoya plant, also known as Hoya carnosa or wax plant, requires warm temperatures to thrive and grows almost exclusively as a houseplant in the United States. Gardeners value hoya for its clusters of waxy, fragrant flowers with pale pink petals and red stars in their centers. The plant may take several years to begin producing flowers each year. In some cases, the hoya blooms twice per year, but only if provided with excellent growing conditions. Suitable for hanging baskets, the plant's long vines trail over its container to create an exotic display in any indoor garden.

Step 1

Plant hoya at the same depth at which it was previously grown in a medium-sized container filled with all-purpose potting soil. Water thoroughly after planting to compact the soil and bring moisture into contact with the roots.

Step 2

Keep the hoya plant in a location that receives bright light throughout the day, such as a west-facing window. Maintain a temperature of 70 to 80 degrees F during the day and about 65 degrees at night.

Step 3

Water the hoya once each week during spring, summer and fall. Reduce watering frequency to once every two weeks during winter, when active growth has ceased. Do not allow the soil to dry out once flower buds have formed.

Step 4

Feed hoyas once each month using an all-purpose houseplant fertilizer. Apply according to the manufacturer's directions for optimal dosage. Water before and after applying to release the nutrients into the soil and prevent injuring the roots.

Step 5

Re-pot hoyas once every four to five years to provide additional room for growth and a fresh growing medium. Increase the size of the container by about 1 to 2 inches each time, as the plant has a modest root system that won't need too much room for additional growth.
