How to Grow and Care for Hoya Sunrise

Hoya Sunrise Care

The vines of these attractive, colorful plants can grow up to eight feet long, so growing them in a hanging basket is a way good way to display their waxy, trailing foliage and give them space. They can also be grown in a pot placed on a table or plant stand. A terra cotta pot will usually provide the best drainage. The colorful blooms vary from white to creamy white to pale pink, with the pink color most commonly seen with more exposure to sunlight. More sun also brings out the reddish color of the foliage.

Obtaining these plants can be tricky, as they’re still somewhat rare in the trade. But there are a number of online retailers who sell them. You might need to do some research to determine which vendors have them in stock.

Light

The hoya sunrise prefers medium to bright, but indirect, sunlight. Too much sunlight can harm the leaves, turning them yellow or brown. Up to two hours of direct morning sunlight is fine, but afternoon sunlight is too strong. Five to six hours of dappled sunlight per day is perfect. You might need to observe how the plant reacts to different locations to obtain the best amount of sun exposure, and that might mean moving it around a bit. It is said that the hoya sunrise obtains its best red foliage coloring when pushed just to the edge of “sun stress,” in other words, gradually giving it a bit more exposure to see if the color intensifies.

Soil

A basic potting mixture of soil intended for succulents, cacti, African violets, and orchids will work fine for a hoya sunrise plant. A soilless mix using peat, perlite andor vermiculite can also work well. The primary factor is to provide a soil mix that allows plenty of drainage and air circulation to keep the roots healthy. If soil is too wet, this plant is prone to developing root rot.

Water

Like other tropical plants that are grown indoors, this one likes to be watered thoroughly but only when the soil is dry. Hoya plants have adapted well over time to seasonal droughts in their native regions, and so allowing the soil to dry out between waterings is what they prefer. Water your hoya sunrise infrequently, every 10-12 days, just enough so that the top layer of soil is moist but not wet.

Temperature and Humidity

The hoya sunrise won’t survive prolonged cold temperatures. Avoid placing it near a drafty window or door. Because it is native to tropical environments, it prefers humidity, as high as 50% to 60%. Most home interiors are dry, so installing a humidifier or placing a saucer of water nearby can be helpful. The hoya sunrise also does not do well in high temperatures, so if the temperature goes above 75 degrees Fahrenheit for an extended period of time, you might place it in a shaded or dark spot to keep it cool.

Fertilizer

Feed your hoya sunrise monthly with a liquid fertilizer that has a higher percentage of nitrogen, perhaps a nutrient ratio of 3:1:2. Fertilize sparingly after watering (never apply liquid fertilizer to dry soil because doing so can damage or even kill some plants). Reduce fertilizing for a few weeks if the tips of the leaves turn brown.

Pruning Hoya Sunrise

Though you should trim off any dead or damaged leaves, don’t deadhead this plant to remove its spent flower bracts. This plant regenerates flower buds from old bracts, so leave them be and you’ll get more flowers. The best time for pruning the leaves is spring or summer after a period of bloom.

Propagating Hoya Sunrise

To propagate hoya sunrise take a cutting and place it in a small pot filled with sphagnum moss as a growing medium. Mist the surface lightly and regularly, and the roots should start to grow within about six weeks.

Common Pests and Plant Diseases

Hoya sunrise is relatively resistant to most pests, but the most common problems they encounter include root rot (usually from overwatering), mealybugs, and leafspot (which has several causes including bacteria or nematodes).

How to Get Hoya Sunrise to Bloom

Hoya sunrise can theoretically bloom continuously but also can benefit from a period of dormancy to help it replenish itself. The best time to do this is in summer after a period of spring blooming. Choose a spot with indirect sunlight or partial shade, which will deter it from forming flower buds too quickly. Check the weather forecast and do this when the temperature does not go below 55 degrees Fahrenheit or above 75 degrees Fahrenheit, for about two weeks.
