Hoya Curtisii are awesome hanging basket plants known for their beautiful foliage.

Main things to know to care for Hoya Curtisii.

  1. Water. Let your Hoya Curtisii dry out completely before watering. When it’s time to water, give your plant a thorough watering.
  2. Light. Place Hoya Curtisii in a place getting bright indirect sunlight (south, east, or west facing windows). This plant can handle some direct sunlight as well.
  3. Fertilizer. Feed your plant a natural or synthetic fertilizer. If using synthetic, make sure to dilute the recipe in half.
  4. Humidity. Hoya Curtisii can handle low to average household humidity, but will grow quicker in higher humidity.

Hoya Curtisii thrive with these plant care tips.

Light

Hoya Curtisii are in the Hoya family meaning they can handle very bright light. This means you can place this plant in a spot getting bright indirect sunlight, and it can even handle some direct sunlight.

A south facing window is a great spot for Hoya Curtisii as long as the plant is placed behind a sheer curtain or a few feet away from the window. You can even place this plant in a greenhouse under plant grow lights as I do with a lot of my Hoya’s.

Hoya Curtisii can handle a spot in your house getting lower light, but don’t have high expectations for the plant to grow into a much larger plant.

Water

Hoya’s like to dry out in between waterings. These plants can handle a little bit of drought so you only need to water when your moisture meter says dry.

You can even stick your index finger about two inches in and check the soils moisture. If it’s completely dry, it’s time to give your plant a thorough watering.

Feel free to bottom water your Hoya Curtisii or place the plant under your faucet to give a good watering.

Soil

Hoya Curtisii thrive in well-draining soil and don’t like to sit in dense, compacted soil.

Since these plants like to dry out in between waterings, it’s important that your plant is sitting in well-draining soil that has good air flow going through the soil. If the soil is too compact, the plant can suffer from root rot.

A simple soil recipe is 50% coco coir, 25% perlite, and 25% worm castings. If you don’t want to make your own soil, you can buy pre-made soil like Fox Farm Ocean Forest potting soil.

Temperature

Hoya Curtisii do well in any home that is between temperatures of 60 degrees F to 90 degrees (15 degrees Celsius to 32 degrees Celsius). These plants prefer the warmer side of things and it helps the plant grow and possibly even bloom in the home.

Fertilizer

Plants need to be fed fertilizer as they need the nutrients to grow and thrive in your home.

There are many types of fertilizer available on the market and these include natural and synthetic fertilizer. If using a synthetic fertilizer, it’s important to dilute the recipe in half as synthetic fertilizers are often too strong and can hurt your plants.

I fertilizer all of my plants with a mixture of Liqui-Dirt and Dyna Gro. Every time I water my plants, they get fed a mixture of my favorite plant food and fertilizer.

You can also use slow-release granule fertilizer which you sprinkle on top of your plants soil.

Humidity

Hoya’s can live in average household humidity in your home, but they prefer high humidity in the 60%+ range. If you don’t have this available, don’t worry, as your plant will naturally acclimate to your home’s humidity.

If you do want to give your plant extra humidity, group high humidity plants together as they create a microclimate of boosted humidity just by being around each other.

You can also place your Hoya Curtisii on a pebble tray with water to add extra humidity around your plant.

Use a hygrometer to check the humidity around your plants.

Propagation

To propagate Hoya Curtisii, all you have to do is take a stem cutting that has a few nodes on the stem. Place the stem cutting in water.

To make things even easier for propagating this plant, I recommend getting a container and placing moist sphagnum moss in the container. Then lay your stem cuttings on top of the damp moss and place in a spot getting sunlight. I’ve found the most success propagating Hoya Curtisii this way.

I like to keep things easy by fertilizing every watering so I don’t ever forget to feed my plants. You can use a slow release fertilizer or a fertilizer you add to water to feed your plant the nutrients it needs.

This is a also great plant to place in a bathroom getting bright indirect sunlight because of the added humidity from showers and baths.

How do you propagate Hoya Curtisii?

You can either place the cutting in water or place the stem cutting on top of damp spaghnum moss in a covered container. I find this one of the easiest ways to propagate cuttings like this because the container adds extra humidity.

As you can see pictured below, I’m growing my Hoya Curtisii propagation in moss.

Can I water my plant using tap water?

I do not use tap water on my houseplants because our tap water is filled with minerals and properties that hurt our houseplants. We instead use a reverse osmosis system and water our houseplants using that system.

You can also let tap water sit out for 12 hours before using it. Depending on where you live, your tap water may be just fine. I live in an area where our water is recycled again and again so our water isn’t the highest quality.

Is Hoya Curtisii toxic to pets?

No, this plant is not toxic to pets.  You can get more information on toxic and pet-friendly plants at ASPCA here.

Common pests

Hoya Curtisii are prone to pests just like any other plant. Common pests include mealybugs, scale, and aphids. Pests can hurt your Hoya Curtisii which is why prevention is key.

Prevent pest infestations on your plant with these tips.

  • Inspect your plant before purchasing. If you’re buying a plant online, inspect your plant away from your other plants.
  • Quarantine your new plant for two weeks and keep away from other plants.
  • When bringing a plant home, treat it with natural or synthetic pest preventative.
  • Regularly check your plants for pests. This is also a great time to clean your plants with a mixture of soap and water.
  • Cut off dead or rotted leaves.

If you ever find pests on your Hoya Curtisii, quarantine the plant away from your other houseplants. Remember that not all pests are bad pests and some pests may even be beneficial for your plant.

You can spray neem oil to get rid of pests or you can use rubbing alcohol to wipe away mealybugs. Use a cotton swop dipped in rubbing alcohol and wipe away bugs and larvae.

Make sure to check all of your other plants as it is easy for pests to spread.

I also recommend Bonide Systemic Granules to prevent pests, particularly gnats.

Bonide Systemic Granules are a great way to get rid of unwanted pests.

Brown tips: If your Hoya Curtisii has browning tips, this may mean your plant is receiving too much sunlight and it’s burning the plant.
