Care Guide
-
Hoyas need bright indirect light, and some can benefit from some direct sun. They do not do well in low light conditions, and need lots of light to thrive.
-
Hoyas are very sensitive to overwatering. Let the soil completely dry before watering, and be sure to let all the excess water drain out. Since hoyas are drought tolerant, when in doubt err on the side of under watering instead of over watering.
-
Hoyas like it warm, with 70 - 85°F as ideal, and nothing below 60°F. They don’t like drastic temperature drops, so keep them away from drafts and vents.
-
Hoyas do well in average household humidity (50 - 65%), and will thrive in higher humidity (65% +) Unlike aroids they do not do well with misting on their leaves, and doing so can cause fungal issues. Use other means to increase humidity in the areas with hoyas.
-
Chunky, airy, well draining mixes are perfect for hoyas. Aroid mixes with lots of bark and other chunky media work well. Hoyas like to be root bound, so smaller pots are okay. Hoya pots need to have plenty of drainage, and terracotta is a good option as the clay pulls moisture away from the roots and helps reduce any excess moisture in the soil.
-
Hoyas are non-toxic for people and pets!
-
Hoyas will climb up trellises - no moist moss poles needed! They just need a solid surface to wrap themselves around and off they go! They can be grown as hanging vines, and if the plant is big enough you can explore both growth types with the same plant.
The leafless vines that reach out from your hoya plant are looking for something to grab on to - don’t cut them back, as they’ll grow leaves eventually! If they don’t find something to grab they’ll fall downwards and grow into a hanging pattern. If they do find something to grab and grow secure, new little leaves will start to bud out of the vine.
Hoya varieties
Hoya obovata
-
This Hoya has fun circular leaves, and works really well as hanging vines. Care is the same as general Hoyas, and these big leaves benefit from being cleaned of any dust often.
Hoya pubicalyx
-
Hoya pubicalyx is one of the fastest-growing Hoya plants, and there are a few ‘splash’ and color varieties. Care is the same as general Hoyas.
Hoya carnosa
-
This is the classic Hoya plant, and it was a very popular houseplace in the 60s and 70s. This Hoya likes being rootbound, but also enjoys being repotted more frequently - up to once a year if needed.
Hoya carnosa 'Krimson Queen'
-
This is a variegated variety of Hoya carnosa - brighter light and warmer temps can lead to more white and variegation, along with bright pink vines! This Hoya likes being rootbound, but also enjoys being repotted more frequently - up to once a year if needed.
Hoya australis ‘Lisa’
-
This Hoya can tolerate some direct sun, and will get a wonderful red tint to “sun stressed” leaves. Unlike the Krimson Queen, this Hoya does not like it’s roots to be disturbed, so repot only when absolutely necessary.
Hoya 'Krimson Princess'
-
Brighter light and warmer temps can lead to more white and variegation, along with pinkish reddish vines! These leaves also can get the reddish tint of “sun stress” with bright light. Also thrives on being repotted frequently - up to twice a year.
