Light Needs

Medium to bright indirect sunlight is ideal. They need a good amount of light to encourage the variegation, if it does not get enough it can fade.

How Often to Water A Syngonium Grey Ghost

Check the soil once a week and only water it if the top half of the soil is dry. You want to avoid over watering as it is the most common problem with aroid like this.

At watering time, it’s a good idea to keep an eye out for pests like Fungus Gnats.

Tip: underwater this plant rather than overwater it, they must not sit in soggy soil as they get root rot easily. Check the soil and only water if mostly dry, and make sure you don’t leave the pot standing in any excess water.


Feed your syngoniums a balanced feed once a month in the spring and summer to encourage growth.

Syngonium Grey Ghost Soil

Use a well draining mix, make sure it has plenty of perlite. If you are using a proprietary potting mix which can be a bit heavy add about 20% perlite.

When To Repot

Syngoniums tend to grow really quickly and they will need repotting at least once a year or more. A good thing to do is check the pots in spring, even if there are no roots growing out the bottom it is worth taking the plant out of it’s pot and look to see if it is root bound, as it will likely grow a lot in the coming growing months so you want to make sure it is in a big enough pot.


50% is ideal for this plant as they will thrive if given a little humidity. If your plant is not in a humid part of the home you can put it in a plant cabinet or give it a pebble tray under it with water in to increase the ambient humidity.

Tip: Keep them humid, aim for 50% or more in the day and they’ll be ok with a bit less at night. You can buy a humidity meter (affiliate link) to keep an eye on maximum and minimum levels.


The ideal humidity for a syngonium grey ghost is 15-30°C (59-86°F). Just don’t let them get down too cold in the winter, so be careful of draughty windows.

Syngonium Grey Ghost Propagation

It is really easy to propagate a syngonium grey ghost as they grow very quickly, follow these steps:

  1. Take a cutting that has at least 2 leaves (one is ok but I find two-leaf cuttings do much better) and make sure the cutting has a node a swell.
  2. Then leave the cutting for about 2 hours for the wound to seal over.
  3. Then pot the plant up in soil or wet sphagnum moss.
  4. Put it in a clear plastic bag, and almost seal it, just leaving a small air hole.
  5. Put in a bright place but out of direct sun, like to the side of a south facing window.
  6. Keep it moist and change the air every few days.
  7. In one to two months it should develop a good root system.
  8. Once it starts growing more leaves form the top you can take the bag off and pot it up.
