With tender loving care, you can grow lush and healthy hoya curtisii even if it is your first plant.

This easy-to-care-for vine needs a bit of light and some watering, and it will be growing all year long indoors.

We consulted with the pros and the home flora growers on keeping your hoya curtisii growing like a weed but not looking like one.

What Is Hoya Curtisii?

The hoya curtisii is a part of the Apocynaceae family. It is a succulent plant with small ½-inch leaves shaped like hearts and are often dotted with silver or gray specks. The creeping vine is delicate, and although it can be slow to start, it grows quickly and fills out nicely with proper care.

– Flowers

The hoya curtisii produces webs of tiny fuzzy blooms once or twice a year. The unique flowers are typically white, yellow-green, or beige with a pink or red center. The flowers are very fragrant, with a citrusy or melon-like scent.

– Other Names

The hoya curtisii is known by several other names. Some of the most common include:

  • Fung wax flower
  • Hoya Aloha
  • Porcelain flower
  • Tiny leaf porcelain flower
  • Wax flower

– Origins

The hoya curtisii is originally from the Philippines, Thailand, and Malaysia. However, you can buy them from just about any nursery or garden store and grow them indoors all year long.

How to Care for Hoya Curtisii

Although caring for your hoya curtisii can be as simple as giving it a drink once in a while, you need to keep it happy. As with any plant, the hoya curtisii likes to have some food and water and maybe a little conversation as well.

– Hoya Curtisii Light Requirements

The hoya curtisii thrives in bright light as long as it is indirect light. In other words, do not put it directly in the sun outside or in a window that gets full sun. If you rotate it and move it from time to time, you can put it almost anywhere.

– Hoya Curtisii Water Requirements

Watering hoya curtisii is pretty simple. You can treat it like a wildflower and just water it after it dries out. It is better to dry it out a bit than to be waterlogged because it is susceptible to root rot. Watering once a week is good enough for your hoya curtisii.

One way to tell if your hoya curtisii needs watering is to test the soil. Just use your finger to see how dry it is. It would be best if you let the soil dry at least two or three inches down. Also, make sure you have the proper drain holes in your pot.

– Soil Requirements

Any kind of high-quality soil that drains well is excellent for your hoya curtisii. You can typically find soil for cacti or succulents at the gardening shop. The best soil for hoya curtisii is two parts soil and one part pumice or perlite.

– Fertilizer

You can add light organic fertilizer to the soil when you plant your hoya curtisii, but you do not have to feed it regularly. Those who grow hoya curtisii will usually top-dress it once with organic compost in the spring.

However, other experts claim that giving your hoya curtisii fertilizer once a month in the spring is best. Use the macro and micro ingredient fertilizer for indoor plants. Mix ¼ teaspoon with a gallon of water and apply once a month.

– Temperature Requirements

Since it comes from a region with a warm climate, your hoya curtisii likes to stay warm. This thrives better when temperatures are between 65 and 75 degrees. However, make sure it does not get lower than 60 degrees at night. Never let their temperature go below 50 degrees.

– Humidity Requirements

Your hoya curtisii is a tropical plant, and it likes to be in humid conditions at all times. If you do not like humidity in your home, give your plant a little water spray or humidifier to keep it happy. Always keep the humidity above 50 percent.

– Pot Size Requirements

Your hoya curtisii does not like being moved often, but eventually, it may need to be repotted. But only go up one pot size. Hoyas do not need a lot of room, and it takes the soil too long to dry out if it is overpotted.

How To Propagate Hoya Curtisii

Hoya curtisii propagation works best with a stem cutting in the soil in the late spring or early summer. The hoya curtisii has small aerial roots under each set of leaves. Make the cutting about three inches long, remove the two leaves above those aerial roots, and put the end in moist soil.

– Rooting in Water

It is often good to root your hoya curtisii in water before putting them in soil. Just put the cut end under the aerial roots in a glass of water until they start rooting. Then, you can transfer them to soil with two parts succulent potting mix and one part perlite.

Common Problems

As with any plant, the hoya curtisii is susceptible to pests and diseases. Sometimes no matter how careful you are, these things happen. The main things to remember are to never over water it, keep it from getting below 50 degrees, and keep it at 50 percent humidity or higher. Keep your eyes open for these issues.

– Pests of Hoya Curtisii

It seems like all plants get bothered by certain pests. For the hoya curtisii, the main critters to watch out for include:

  • Aphids
  • Fungus gnats
  • Mealybugs
  • Spider mites

1. Aphids

These are the most common type of houseplant pests. These soft little bugs are yellow-green and are under ¼ inch long, so they are difficult to spot. But once you spot them, all you have to do is spray them with your sink sprayer, and they will be gone. They especially hate cold water.

Once you get rid of the original infestation, spray your hoya curtisii with neem oil or insecticidal soap. Do this every other day for two weeks. Maybe, you can sprinkle a bit of catnip over your plant. Aphids hate catnip. Just keep your cats away.

2. Fungus Gnats

About the size of a fruit fly, a fungus gnat is about 1/16 to 1/8 inches long. They are typically found in moist soil where they like to lay their eggs. You most likely will not even notice them until they multiply enough to cause damage. They eat the roots, and the lower leaves will turn yellow and fall off.

There are many traps you can use to get rid of these tiny terrors. A sticky card trap is just a yellow notecard with a sticky adhesive. Put a few on top of the soil, and they will get stuck to the adhesive. Be sure to use yellow because they are attracted to the color.

Flypaper is also suitable for catching those gnats. However, they are sticky and tend to get stuck to things you do not want any of that to happen. Only use them if the sticky cards do not work.

Once the fungus gnats are gone, prevent their return by keeping the soil dry, which is best for your hoya curtisii anyway. You can also use mosquito dunks to keep the bugs away. Or cover the drain holes with fabric to keep them out of there because sometimes they multiply in the drain holes

3. Mealybugs

At about 1/20th of an inch, the minute pink mealybugs are covered in white wax, which is what you will often notice. You may see a fuzzy white spot where the stem and leaf meet. These are the mealybugs feeding on your hoya curtisii.

You may first notice that your hoya curtisii is starting to lose leaves or turn yellow. Or it may just look wilted. Eventually, they will stunt the growth and even kill the plant if you let it go too long.

If you see them early, cut off the stem they are feeding on to get rid of the whole bunch of them. Then you can spray the rest of the plant with water and insecticidal soap. Neem oil will work for this pest too.

4. Spider Mites

If you see webs all over your hoya curtisii, you probably have a case of spider mites. They are incredibly tiny bugs that suck the sap out of your plant until it dies. These small mites are only about 1/25th of an inch long, so you will see their web or their damage rather than seeing them.

To get rid of the spider mite, you will have to be diligent. They often start their web under the curled edge of leaves. Like the aphid, these bugs hate cold water, giving them a cold spray to blow them away.

Once you get rid of the initial colony of spider mites, spray or wipe down your hoya curtisii with neem oil or insecticidal soap to keep them away. Do this once a week or whenever you see new webs starting to form.

– Leaf Problems

Hoya curtisii leaves can have issues sometimes, just like other plants.

Some of the problems that can crop up include:

  • Yellowing leaves can be caused by too much water. Make sure your hoya curtisii has proper drainage, and do not overwater it.
  • Thinning leaves are a sign of stress in your hoya curtisii. Make sure the water is draining well and that the soil is not too compacted.
  • Misshapen leaves are often a sign of stress as well. As with other issues, be sure your plant is not being over- or under-watered. Also, make sure your hoya curtisii is not getting too hot or too cold.
  • Wrinkly leaves are a sign of not enough water. Your plant is thirsty, or you need higher humidity in the room.
  • Dropping leaves right after they grow is a sign of too much water or not enough water. Make sure you are giving your hoya curtisii enough water but not too much.
  • Leaves that do not grow can mean the plant is going dormant because of a change in its environment. Did you move it from another room? That could be the problem.
  • Vines dying back is a sign of not enough sunlight. Give your plant more light by rotating it once in a while or move it closer to a sunny window.
