Hoya memoria
Water quality isn’t as much of an issue with this group, though I’m sure they won’t object to some pure water. When increasing light, slowly acclimate the plant to avoid burning of leaves. Plants should not touch most lamps/lights as it can cause burning. Hoya can also do very well under artificial lights or a sunny windowsill. You want to give it as much light as needed for good leaf development and strong/ growth. You may have to adjust the amount of light that particular plant is getting- might be too much that it scorches or not enough. As a baseline, I would recommend temperatures 65-85F, not going below 60F, which is why they tend to do well in average household temperatures (if not on the warm side of house temps).Īgain, a widely varied topic depending on the type and species that you’re going, but most Hoya will do well with 500-2500 footcandles (aka 5000-26000 lux, aka 100-500 umol/m2/s PPFD). Research the species you’re looking to grow. For highland species, it seems that they don’t want it hot, but prefer intermediate temperatures and want a cooler night period. For the “lowland” type species, they are usually liking warm and humid temperatures without large drops in temp at night. It is not easy to give a blanket statement.
When dealing with Hoya species, there is a lot of variation in preferred temperatures as Aroids come from many different elevations. Bill’s Orchids, LLC Basic Culture Sheet – Hoya
