A Beginner's Plant Care Guide to Wax Vines, Hoya (Wax Plants)
Common Name: Wax plant, Wax Flower, Porcelain Flower, or just Hoya
Botanical Name: Hoya species (see below for available varieties)
“Hoya Hoarding” is a real thing - there are many avid Hoya collectors out there! Finding and adding new Hoya varieties to your growing indoor plant collection is almost as irresistible as acquiring art or antiques! From the delicate hanging needle-like foliage of the Hoya linearis, to the bold and glossy leaves of the Hoya Australis, these indoor plants fill many homes with elegance, beauty, and glamour.
Hoya will give you bursts of flowers in the right environments. However, their bloom time is brief, so keep your eyes peeled for their fragrant and fleeting offering. Hoya are easy-care indoor plants if you have the medium to bright indirect light that they need. They don’t require constant watering and do not require high humidity levels. But note -- the species with thinner leaves will need more water than those with waxy leaves.
These houseplants like lots of bright, indirect sun. These Hoyas are able to tolerate medium light, but they’ll become weaker, leggy, and produce fewer leaves in lower light.
Let your Hoya indoor plants dry out between waterings. Soak the soil thoroughly until the water drains out of the drainage holes. You’ll need to water more when they’re receiving more light, so adjust accordingly. Avoid over-watering. When the colder months arrive, cut back on watering; in wintertime, only water when their soil is completely dry.
Most Hoyas love warm environments - 65-85℉ - and should be kept away from drafty windows and doorways during the colder months.
Although Hoyas can handle most household humidity levels, they will grow more rapidly when the humidity is higher than 60 percent. Do what you can to increase the humidity for these tropical, hanging, indoor plants. Try adding pebble trays filled with water under your indoor plants, group plants together, or use a cool mist humidifier.
For Hoyas, a higher nitrogen fertilizer encourages foliar growth. When they’re about to bloom, switch to a higher phosphorus content. Fertilize with a complete liquid fertilizer or fish emulsion twice a month during the summer. You can also apply a top dressing of worm castings or compost in the spring as this acts like a slow-release fertilizer. Only fertilize during the growing season (spring through summer).
- Hoyas like to be root bound so don’t be so quick to repot!
- You can train your Hoyas to grow up a pole or some other support - if you like that look.
- When you find the right spot for your Hoya, try not to relocate it.
