Hoya

Hoya Collection General Care

Known for their large, waxy leaves and beautiful flowers, Hoya plants are a versatile addition to any home garden. Ideal as trailing plants or just in a pot, members of the Hoya family come in various shapes and sizes. Our Hoya collection includes the trailing and potted versions of Hoya Kerri Heart, Hoya Wayetii, Hoya Pubicalyx Pink Silver, Hoya Australis Lisa, and the Variegated Hoya Carnosa.


The best way to identify Hoya plants is through their leaves. For example, the Hoya Kerri Heart features bright green, heart-shaped leaves. The Hoya Pubicalyx Pink Silver features longer, oval-shaped leaves, and the Hoya Wayetii’s leaves are even longer. The Hoya Australis Lisa and Varigated Hoya Carnosa feature round, light-colored leaves with dark edges, but the Australis Lisa’s leaves are circular while the Carnosa’s are teardrop-shaped.

General Care

Most members of the Hoya family come from Asia and Africa and will prefer warmer temperate climates. While Hoya plants of all types have similar care needs, some still require specific care to thrive. Check out our specific care guide blogs for more in-depth information regarding your particular Hoya plant. 

Light

Hoyas prefer bright, indirect light, similar to a succulent. And just like succulents, their leaves cannot tolerate harsh sun, especially in the afternoon. To ensure your Hoya gets at least six hours of bright, indirect sunlight each day, place it in front of the east or south-facing window. In the east, direct morning sunlight is far less harmful than the afternoon sun. Facing south, your plants will receive steady amounts of sunlight for most of the day.


On occasion, members of the Hoya family will tolerate medium light levels. However, they may not grow as quickly or appear paler in color.

Soil

Well-draining soil is a must for Hoya plants, although they aren’t too picky about their soil. To ensure your soil has the best possible air circulation, modify a traditional potting mix by adding some perlite and peat moss to increase drainage. You can also make your own potting mix with one part organic material to one part inorganic material– we recommend using peat or compost for organics and perlite for the inorganic part.

Water

Hoya plants need lots of water but prefer not to sit in wet soil for extended periods. When you water your Hoya, do so once a week, letting any excess water drain completely through the bottom of your pot. Water again only when the first inch or two of soil is dry to the touch. For best results, water your Hoya using the bottom-watering technique or by watering deeply using a single-hole watering can or watering bottle.

Temperature and Humidity

Hoyas need warm temperatures around 60 to 80 degrees Fahrenheit. In addition, they’ll also need more humidity than other houseplants. Keep your humidity around 60% near your Hoya to help it thrive. To increase or control humidity, place a humidifier near your Hoya or mist it regularly.

Fertilizer

Hoyas need nitrogen-rich fertilizer to help keep their leaves lush year-round. To fertilize, add some water-soluble fertilizer to your watering routine during the summer growing season, and add a little compost to the top layer of soil in the spring. 

Potting and Repotting

Surprisingly, Hoya plants prefer compact conditions in their pots, so you won’t need to repot them as often as other houseplants. Instead, repot your Hoya once every two years or whenever the roots begin to stick out from the pot’s drainage hole. When choosing a pot to house your Hoya, make sure it’s made from a porous material like concrete, terracotta, or ceramic to improve drainage.

Blooming

Although they’re known for their bright foliage, Hoya plants also sport a variety of colorful flowers during their summer growing season. To encourage blooming in your Hoya plant, increase the amount of sunlight they receive by a few hours each day. We also recommend switching to a phosphorous-based fertilizer just before the blooming period. 

Pruning

Under the right conditions, trailing Hoya plants can grow up to 20 feet tall! However, not everyone has the space to manage a twenty-foot vine. Pruning your Hoya regularly can help keep it under control. To prune your Hoya, cut off any unruly parts as close to the base of the plant as you can. When pruning, always use a clean, sharp pair of scissors. Any healthy cuttings you have can be used for propagation later!

Propagation

To propagate your Hoya, take a pruned cutting and strip the lower inch of its leaves. Then, let the cutting callous over for a day. After it’s calloused, dip the cut end into a rooting hormone if desired, and stick the cutting into a pot of fresh, moist soil. Mist your soil regularly and cover it with plastic wrap to create a tiny greenhouse to trap moisture. After about two weeks, tug on your cutting to check for root growth.
