How to Grow Hoya Plants

Light

Like all plants, hoya requires the proper lighting to thrive. They prefer bright indirect light, so a spot on a windowsill with morning light should work well. Keep them out of the harsh afternoon light as they may become burned or sun-stressed. Hoya plants can survive in lower light situations but are less likely to grow and bloom.

If you can’t provide hoya plants with the right amount of sunlight, opt for a grow light instead. There are many to choose from, whether you opt for a lightbulb for the lamp in the room or a specific grow light set up.

Potting Media and Fertilizer

Hoya plants prefer a well-draining potting medium with good air circulation. A soil-free mixture featuring plenty of organic materials usually works best. Look for chunkier options that include peat moss, perlite, and pine bark. These mixtures provide plenty of aeration and drainage, which are essential to a hoya plant’s health. You can also mix the potting medium yourself.

Fertilizer will also improve the fertility level of the potting medium, which will provide nutrients that help the plant grow. Liquid fertilizer is usually the best option, but you should always read the directions on the specific bottle you purchase when it comes to application.

Water, Temperature, and Humidity

Hoya plants require regular watering in the warmer months from spring through fall. In the winter, you should water less frequently. Always allow the soil to dry out between waterings. You can stick your finger in the first inch of the soil–if it’s dry, it’s usually time to water. The leaves will also become softer when the plant needs watering.

Hoya plants prefer a humid environment, as do many tropical plants. Misting is a good way to create humidity, but you can opt for a humidifier as well. Hoya is also a great bathroom plant since they love moisture.

Trellising Hoya Plants

If your plant seems leggy or you want it to appear denser, a trellis is a great option. The tendrils of hoya plants tend to naturally climb and attach themselves to surfaces, so a trellis will be easy to implement. Simply wrap the vines around the trellis, going upward. The plant should continue to grow up the trellis.

General Maintenance

When it comes to general maintenance, there are a few things that you should take note of. First, clean the leaves of hoya plants (and all houseplants), removing any dust and debris with a damp microfibre cloth. A layer of dust can block the plant’s ability to photosynthesize and its ability to grow.

Keep a keen eye out for bugs, as pesky houseplant critters can hurt your plant’s growth and overall health. Also, hoya plants do well when they are root-bound, so they only require a larger pot every few years. You should repot the plant as necessary to ensure it stays happy and healthy.

How to Induce Hoya Blooms

Hoya plants bloom with the proper care, so florals on your plant are a good sign. Check out the key tips for inducing hoya blooms below.

  • Lack of light is usually the main reason hoya plants don’t flower, so remember to keep them in bright indirect light.
  • Since hoya plants prefer to be root bound, give them ample time to grow and mature into their pots.
  • Fertilize and water often during the growing season to help the plant thrive.

How to Prune and Propagate Hoya Plants

While you might feel tempted, don’t cut off bare tendrils. Over time, these tendrils will grow leaves and peduncles for flowers. If you remove them, you may be stunting the growth of your hoya plant. After the hoya has flowered, be careful not to damage the base of the flowers called the peduncles. These will usually produce more blooms in the future.

If you think the plant looks a bit busy, you can always trim and propagate a few vines. Use sterilized scissors or pruning shears and cut four to six inches of the stem at a 45-degree angle below a node or aerial root. Submerge the stem in water and wait for the roots to grow. You can start a new plant or add it to the mother plant once the cutting has established roots.

Let Us Know How it Grows!

While there are many varieties of hoya plants, they generally require the same care. Proper lighting, potting media, watering techniques, and general maintenance should help the plant grow and thrive. And if you want to see those oh-so-dreamy blooms, the key is bright, indirect light.
