The Hoya Gracilis (a.k.a. Hoya Memoria) is a beautiful vining epiphytic hoya with silver speckled leaves and raspberry colored leaves, native to Indonesia. They are relatively easy to care for, and moderately easy to bloom.
Tip: we recommend Etsy for buying plants. Look for the best rated seller you can, and try to buy as close to your home as possible so the plant does not travel too far.
Bright indirect sunlight is ideal, they will be ok in medium too, but you want it as bright as possible to encourage blooming. No direct midday sun, but they can be ok with some direct early morning or late afternoon sun, a little bit of direct sun can help to encourage flowering.
Check the soil each week but only water it if the soil is dry or almost dry. They really do not want to sit in wet soil, root rot is the biggest killer of hoyas. They have not developed to grow in soil, they grow in tree bark int he wild, so planting them in normal soil can lead to root rot very quickly if you water it too much.
Tip: if you have your plant inside another pot, make sure to tip out any excess water from the external pot about 5 minutes after watering. The soil must not be allowed to get water logged as they hoyas can get root rot easily. Remember they grow in tree bark in the wild and do not like to sit in wet soil.
Feed them a balanced feed monthly in the spring and summer to encourage growth.
They will not need repotting every year, but check the roots in spring time and repot them to a bigger size if needed.
60% is best, they thrive in humid air. They are used to living in rain forests in the wild. They will be fine in lower humidity, but the higher the better to encourage flowering.
In the daytime 15-35°C (59-95°F) is a good range, and down to 5°C (41°F) at night.
How to Propagate Hoya Gracilis
Propagate hoya gracilis by taking stem cuttings, you can cut off a whole branch and then chop that into smaller sections that have at least 2 leaves and at least one more node that you can strip the leaves from. This will be under the soil. Put the cuttings n soil with the naked nodes pushed in to the medium, then cover it with a plastic bag to up the humidity. Leave the bag a bit open to allow air to circulate. Keep it in indirect sunlight or a couple of months while it roots. You’ll know when it has rooted well as the cuttings will start to put out new growth from the top of the plant.
