The Hoya Silver Dollar thrives in bright, non-direct sunlight. These plants can tolerate various light conditions, including partial to full sun, but they perform best in full sun exposure. They appreciate sunny rooms and windows when grown indoors.

-Watering Needs

-Temperature and Humidity

Though Hoyas can adapt to different temperature and humidity levels, they prefer warm and moderately humid environments. Monitor indoor temperatures and humidity levels to ensure a comfortable environment for your Hoya Silver Dollar.

-Soil and Fertilizer

Plant your Hoya Silver Dollar in a well-draining, lightweight soil mix to encourage healthy root growth. Apply a balanced, water-soluble houseplant fertilizer with a ratio of 5-10-5, 8-8-8, or 10-10-10 every three to four weeks during the spring and summer months to provide essential nutrients.


Hoya Silver Dollar plants are non-toxic to both humans and pets, making them a safe addition to any indoor living space.

Propagation Techniques

Propagating a Hoya Silver Dollar plant can be done using a few different methods.

Stem cuttings:

  1. Cut a healthy section of the stem, ideally with at least two nodes, and remove the lower leaves from the cutting.
  2. For optimal results, it’s essential to provide a well-draining soil mix to prevent rot. A combination of potting soil, perlite, and orchid bark could be an excellent mix for propagating Hoya Silver Dollar cuttings.
  3. Afterward, place the cutting in a small container filled with this soil mix, ensuring that at least one node is buried in the substrate.

Water propagation:

  1. Place the stem cutting in a container of water, ensuring that the bottom node is submerged.
  2. Change the water frequently to prevent stagnation and bacteria growth.
  3. Once the roots develop, transfer the cutting to a suitable soil mix for optimal growth.

To encourage successful propagation, provide your Hoya Silver Dollar cuttings with the following conditions:

  • Indirect sunlight: Cuttings should be placed in a location with bright, indirect light. Avoid exposing the cuttings to direct sunlight, as this could cause the leaves to burn or dry out.
  • Humidity: Maintain a high humidity level around the cuttings, as this promotes root development. You can achieve this by placing a plastic bag or cloth over the cuttings or using a humidity tray.
  • Temperature: Keep the cuttings in a warm environment, somewhere between 70°F and 80°F (21°C to 27°C). Cooler temperatures may slow down root development and hinder the propagation process.
  • Patience: It’s essential to remember that Hoyas, including the Silver Dollar Hoya, can be slow to develop roots. Allow the cuttings enough time to establish roots before transplanting to a larger container.

By following these propagation techniques and providing the necessary conditions, you should be able to successfully achieve new Hoya Silver Dollar plant growth.

Common Pests and Diseases

The Hoya Silver Dollar plant, also known as Hoya carnosa, is generally a low-maintenance plant with few pests and diseases. However, there are still a few potential issues to watch out for to ensure proper growth and care for the plant.

One of the primary pests affecting Hoya Silver Dollar plants are aphids. These small, soft-bodied insects can cause damage by sucking sap from the plant, leading to discolored and distorted leaves.

Aphid infestations can be controlled with insecticidal soaps, neem oil, or by introducing natural predators such as ladybugs.

For minor infestations, a simple solution of water and dish soap can be utilized to remove the mealybugs, while larger infestations may require a systemic insecticide.


In addition to pests, Hoya Silver Dollar plants can be prone to root rot, a common issue caused by overwatering. To prevent this problem, it’s important to use well-draining soil and avoid letting the plant sit in standing water.

If you notice signs of root rot, such as wilting leaves, remove the plant from its pot, trim away the affected roots, allow the plant to dry, and then repot it in fresh soil.

Other diseases affecting Hoya Silver Dollar plants may include leaf spot, caused by a fungal or bacterial infection. This can be treated by removing the affected leaves, improving air circulation around the plant, and applying a suitable fungicide or bactericide if necessary.
