Recommended Potting Mix

Hoya macrophylla requires well-draining soil with alkaline and calcium. It will grow most comfortably with the right base of soil mix that is easy to combine such as equal parts of the following: perlite, cactus mix, and organic mix rich in charcoal. Your regular potting mix can be a substitute for the cactus mix if you don’t have any.

Lighting Requirement

Since Hoya macrophylla is not sunlight-hungry, you must place it in an area that does not get much sun. You can place it in an east-facing window where it can get enough light. When deciding to hang your Hoya macrophylla, avoid placing it to your window where the sun is directed or it gets bright light.

Direct sunlight can give you lousy Hoya leaves, so it’s better to avoid direct sunlight. If you think your macrophylla looks gorgeous as an outdoor plant, then make sure to place them with no direct access to sunlight. A shaded patio or under a canopy of trees.

Watering Needs

Talking about a low-maintenance plant, watering Hoya macrophylla doesn’t need to be frequent. As long as its soil is moist, your Hoya is doing good. To be able to give the proper dampness that your Hoya needs, it is better to check the surface and the drain holes beside and under your pot. If these parts are all dried up, then it’s time for your Hoya to drink up.

When watering your Hoya, make sure to soak it to assure that it is getting enough water, soak—but never drown, thorough watering is needed because over-watering might lead the plant to root rot or wither. Before putting it right back in its place, make sure you drain it well. Another tip, you can use distilled water or even tap water to water your Hoya plants.

Temperature & Humidity Requirement

Hoya macrophylla ideal temperature is between 65 and 80oF (18 to 27oC). They love it warm and cozy. And because its natural habitat has a tropical kind of climate, your Hoya might hibernate, or go into dormancy when the temperature drops a little. Keeping your Hoya in a bright place and waiting for its time to wake is the best thing to do during these sleepy moments.

Hoya macrophylla likes it humid, and unless you have a terrarium, you cannot give the plant the best humidity it wants. You should know the area’s humidity levels before placing your Hoya macrophylla there. By spraying a decent amount of water on its soil surface, it can go through the day without feeling like drowning at night.

Though this plant doesn’t need high humidity, a humidifier or placing it together with its fellow hoya plants or succulents may also help, though sitting the plants beside each other is not that recommended because they are prone to fungi.

Fertilizer Requirement

The best time to apply fertilizer on the plant is during its growing season. Though Hoya macrophylla only requires to be fertilized once a month, it is not really recommended to fertilize it during winter when your Hoya is in its sleeping or dormancy period.

Organic fertilizer is enough to help your Hoya macrophylla grow, and unless you want it to grow quicker than usual, do not spray fertilizer on it more than once a month.

Propagation

One of the best ways to grow your Hoya macrophylla collection, or to give them away to your circle of friends, is to propagate it. And Hoya macrophylla propagation is easy and requires less effort. By cutting off a healthy stem, preferably not the budding ones, including two nodes and a leaf or two, your next Hoya is ready to live.

Though sphagnum moss makes it easy to propagate, without it, the propagation can still be a success. Place your stem cut to water and wait for two to three weeks for the plant’s roots to grow. Once its roots appear, you can re-pot your Hoya and poof! Another Hoya plant grows.

Growth Zone

Do not expect the Hoya macrophylla plant to grow quickly, as it is really a slow-grower. Though it can grow 5-7 feet tall, depending on how you maintain it, this plant is a good houseplant when you live in a country with generous humidity and sunshine. But if you live in countries with cold temperatures, it is best to maintain a regular indoor plant size as it has to stay indoors due to cold seasons.

Potting and Pruning

Your Hoya plant doesn’t need a large pot to grow for it prefers bounded roots. A small to medium-sized pot with drain holes is enough for the plant to grow comfortably. (The plant needs good drainage for it to grow) Since this plant is a climber, support for the plant’s leaves to climb would be a good help. Your plant may need repotting after a year or two, depending on the status of the soil, since in the longest time it gets acidic, or your Hoya plant grows a little bigger, it does not mean you have to re-pot on a bigger container, remember that Hoya loves its roots bounded.

Remember to prune your plant when dry or yellowish leaves appear, cutting damaged foliage and stems will also help the plant to re-grow into new stems. When you choose to keep your plant indoors, you may trim it according to the length that you like.
