How to Propagate Pilea Glauca

This plant can be propagated via three different methods. These are propagation via stem cutting in soil, propagation via stem cuttings in water, and via pups. Let’s look at each of these in detail.

Propagation in Soil

Bonide BND925 Bontone II

This process should be done during spring so as to reduce the chance of shock.  The steps for doing this are as follows:

  1. Using a sterile cutting utensil, cut off a healthy stem that includes a leaf and a node
  2. Dip the bottom of the stem cutting in a rooting powder
  3. Plant the cutting in a container filled with potting soil
  4. Water the potting soil and keep it moist but not soggy
  5. Set the container in a warm spot that gets plenty of bright, indirect sunlight
  6. Care for as a regular Pilea Glauca plant

Propagation in Water

This process should be done during spring so as to reduce the chance of shock.  The steps for doing this are as follows:

  1. Using a sterile cutting utensil, cut off a healthy stem that includes a leaf and a node
  2. Set the stem in a container filled with water
  3. Cover the plant with plastic wrap that has a few holes in it for ventilation
  4. Set the container in a place that gets bright but indirect sunlight
  5. Once roots appear, plant the stem in a container filled with sandy potting soil
  6. Care for as a regular Pilea Glauca plant


This method doesn’t require any extra effort on your part. Just care for the plant properly and it will reproduce itself naturally through small baby plants called pups.

Pilea Glauca Growing Conditions


These plants are rather easy to care for as long as they are provided with the right amount of sunlight, plenty of room for their roots to grow, and adequate warmth. Because they come from a warm and humid environment, it may be necessary to provide them with supplemental heat and warmth.

They require temperatures that range between 70 and 80 degrees Fahrenheit with humidity levels ranging between 60 and 90%. To provide these temperatures and humidity levels, consider using the following equipment:

How to Plant Pilea Glauca

A healthy Pilea Glauca will need to be repotted every two to three years. This is a chance to provide the plant with fresh soil that contains necessary nutrients for the health of the plant and to provide the plant with more room for its root system to spread out. Signs that a plant needs repotted are:

  • Stagnated growth
  • Compacted Soil
  • A plant that looks too big for its current container

The steps for repotting a Pilea Glauca are:

  1. Fill a new container that is two inches larger than its previous container with potting soil
  2. Create a hole in the soil for the plant to set inside
  3. Carefully remove the plant from its current container by laying the plant on its side and then pulling the pot off the root system
  4. Gently dust off any excess soil from its roots
  5. Set the plant into the hole in the new container
  6. Spread the soil around so that the plant is secure in its new container
  7. Water the plant
  8. Set it in a warm spot with indirect sunlight

Pilea Glauca Potting & Soil


Soil pH levels are not a big concern for Pilea Glauca plants, but what does matter to these plants is whether or not the soil drains well while still being able to retain a little moisture.  When deciding on which type of potting soil to use for your Pilea Glauca, be sure to look for soil that includes peat and perlite.

The following are some really great soil options to use with Pilea Glauca plants:

Just getting the soil right will not prevent drainage issues for your plant.  Remember, to get a plant container that can also drain off excess water.

Pilea Glauca Water Requirements

The most important thing to remember about watering this plant is the quality of the water given to it. Pilea Glauca is very sensitive to minerals in the water, and therefore, should only be watered with rainwater or distilled water that has been allowed to reach room temperature. If these types of water are unavailable for you, then you can use tap water as long as it has been set out for at least 24 hours so that some of the minerals have time to evaporate.

To reduce the risk of root rot, always test the plant’s soil before watering it.  If the top inch of the soil is dry, then the plant can use a drink; however, if the soil is still moist, the plant does not need any more water.  Different seasons of the year will require different amounts of water.  Winter usually requires fewer watering sessions than either spring or summer.

When you do water the plant’s soil, be sure to water it evenly and thoroughly so that excess water flows from the container’s drainage holes. You can also water it in the soak and dry method, but be sure to allow the soil time to fully drain off excess water.

Take advantage of modern technology by using a plant watering app.  This type of app can help track when a plant has been watered, set reminders to water it, and get answers to common plant care questions.

Pilea Glauca Light Requirements

These plants should be set in a place that gets plenty of bright, indirect sunlight.  These plants can, however, benefit from a few hours of direct sunshine in the morning. Just don’t leave them in direct sunlight for too long or during the hottest parts of the day since this will cause more harm than good.

Test your indoor lighting situation with a light meter to ensure that your plant is receiving the amount of sunlight it needs.

  1. Remove the plant from its container
  2. Wash off all the dirt from its roots
  3. Cut off any roots that are rotten
  4. Replant the plant in a clean container with fresh soil
