Caring tips for Hoya Sigillatis

These plants are quite easy to care for, but keeping them in the conditions they prefer is important for ideal growth. We have listed some basic requirements that can help you grow your plant with mesmerizing colors.


We advise you to keep your plant under bright, indirect sunlight, but please avoid placing it under direct sunlight as it can damage sensitive leaves.

They live under shades of large trees in their natural habitat, so placing them under partial shade would make these plants feel at home, encouraging them to produce mesmerizing colors. However, if the plant’s leaves turn red, you should change the location as they are the effects of harsh sun rays in most cases.


They prefer to grow under slightly acidic to neutral soil, so keep the pH level between 6 and 7 for ideal growth. Moreover, you can prepare a good potting soil mix with the help of charcoal, perlite, and pine bark mixed with your regular potting soil.


We recommend that you water the plant when the upper layer of the soil is dry. Overwatering the plant can cause root rot, so make sure that you do not leave the plant’s roots under standing water for too long.


A temperature range of 60 to 95 degrees Fahrenheit is ideal for these plants to grow. Keep a stable temperature and avoid placing them under extreme conditions for too long.

They are not frost-hardy, so bring them inside the house if you live in an area with freezing winters. Temperatures below 55 degrees Fahrenheit can completely stop your plant’s growth.


These plants prefer a high humidity level of 65 to 85 percent. It is difficult to maintain such high humidity levels in an average household, so we advise you to mist your plant or use a humidifier to maintain a stable and high humidity level.


Feed the plant with any standard houseplant fertilizer once a month from spring to summer season. Feeding the plant helps boost its overall growth pace, but make sure that you completely cut back on fertilizing during the winter when the plant goes inactive.


Pruning these plants depend on how you use them. If you want to hang them from the basket, we recommend you do minor trimming once a month.

They can grow quite tall and cover up a lot of space if you do not prune them, so occasional pruning is an essential practice to control the plant’s overall growth.

Pests and other diseases

Pests such as mealybugs, scales, spider mites, and aphids are commonly seen in these plants. You can use neem oil sprays to eliminate all these pests and protect the plant from getting infected.

Propagating Hoya Sigillatis

They can be propagated using the stem cutting method. There are a few tips that can help you get the best results.

  • Choose a healthy stem and make a clean cut, ensuring that a few leaves remain intact to the stem.
  • Place the cuttings in the water and wait for the roots to develop.
  • Do not drown the leaves in water.
  • Place the roots a few inches below the soil.
  • Water the plant more often in the early stages of its growth.
