Pilea microphylla, also commonly known as artillery plant, is an annual or short-lived perennial. It’s best recognized by its many pairs of small, fleshy green leaves that give the plant an almost fern-like appearance.
Tiny green flowers appear during the growing season but they aren’t very prominent. However, they do release a burst of yellow pollen, which earned the plant its common name.
Artillery plants grow best in warm conditions and require bright, indirect light, along with moist but well-draining soil.
The artillery plant, also known as Pilea microphylla, is a fun and easy-going houseplant that adds a lively touch to any indoor space. With its fleshy, bright green leaves arranged in pairs along creeping stems, it has an attractive fern-like appearance. But what makes this plant truly distinctive is the tiny flowers it produces during the growing season. They burst open and release yellow pollen into the air, earning the artillery plant its catchy common name.
When it comes to successfully growing this plant indoors there are a few key things to know about caring for it. One important factor is understanding the artillery plant’s light requirements. I’ll explain exactly how much sunlight it needs to thrive. Read on for a complete care guide covering water, soil propagation, and troubleshooting tips as well!
Optimal Sunlight Conditions for Artillery Plants
The artillery plant does best with bright, indirect sunlight. While it tolerates some direct sun, too much of it will scorch the plant’s delicate leaves. I recommend placing it in an east or west-facing window where the sunlight is naturally filtered. A sheer curtain can also help diffuse the rays. South-facing windows tend to have very intense light, so be sure to filter it. North-facing windows usually don’t provide enough light for this plant.
During the warmer months, you can place the artillery plant outside in a spot that gets a mix of sun and shade. Just bring it back inside before temperatures dip below 60°F
If the plant’s leaves start to turn yellow, it’s likely a sign that it needs more sunlight. On the other hand, if the tips turn brown and crispy, your plant is probably getting too much direct sun. Make adjustments until you find the sweet spot!
Water Requirements
The artillery plant has moderate watering needs. I suggest watering whenever the top inch of soil becomes dry to the touch. During the growing season, this is usually every 7-10 days. Reduce watering frequency in the winter when growth slows. The plant stores water in its thick leaves, so it tolerates occasional droughts quite well. But extended periods of dryness will cause leaf browning and drop.
Make sure the pot has drainage holes to prevent soggy soil, which can lead to root rot. Tip: Allow excess water to drain out after watering, then dump any water that collects in the saucer.
Ideal Soil Conditions
The artillery plant grows best in loose, well-draining soil that retains some moisture. I recommend using a quality potting mix formulated for indoor plants. You can also make your own blend by combining:
- 2 parts potting soil
- 1 part perlite or coarse sand
- 1 part peat moss or coco coir
The sand and perlite provide drainage while the peat and coco coir help retain moisture. Re-pot in fresh soil every 2-3 years to replenish nutrients. Choose a pot that’s 2 inches larger than the current container.
Fertilizer Needs
During the active growing season from spring through summer, you can fertilize monthly with a balanced liquid fertilizer diluted to half strength. But go easy on fertilizing, as excess nutrients can burn the artillery plant’s roots. I personally find that my plant grows quite well with occasional compost top-dressing rather than chemical fertilizers.
Humidity Preferences
The artillery plant appreciates average to high humidity but doesn’t require special measures to increase it. Simply grouping plants together helps raise the ambient humidity. Regular misting also provides a humidity boost. Just be sure to keep the leaves dry going into nighttime to prevent disease.
If the air is very dry, use a pebble tray or humidifier nearby. Avoid drafty areas as well.
How to Propagate Artillery Plants
Propagating pilea microphylla is quite straightforward! You can grow new plants from stem cuttings or division.
Stem cuttings – Cut a stem right below a leaf node. Remove the bottom 2 sets of leaves and place in water or moist potting mix. New roots will sprout at the nodes in a few weeks.
Division – Carefully divide at the root ball, ensuring each division has some roots and foliage. Re-plant divisions in small pots.
Troubleshooting Common Problems
-
Yellow leaves – This usually indicates too little light. Move to a brighter location.
-
Dry, brown leaf tips – The plant is getting too much direct sun. Filter the sunlight.
-
Leaf drop – Overwatering and soggy soil causes leaves to drop. Allow soil to dry out between waterings.
-
Leggy growth – Insufficient light leads to weak, leggy growth. Provide brighter light to compact growth.
With the proper care, the artillery plant makes an easy, rewarding houseplant. Just be sure to provide it with moderate humidity, loose and moist soil, filtered sun, and average room temperatures. Avoid overwatering, and fertilize lightly, for the healthiest plant possible!
Pilea Microphylla Care
Here are the main care requirements for growing Pilea microphylla:
- Plant in loose, well-draining soil.
- Choose a location with bright, indirect sun.
- Water regularly, but allow the soil to dry out between waterings.
- Fertilize lightly during the growing months if desired.
Light
Pilea microphylla does best with part sun conditions. It should receive plenty of bright, indirect light but too much sun will have a detrimental effect on the plant.

Is artillery fern invasive?
How do you care for an artillery plant?
The Artillery Plant is generally easy to care for, but like all plants, it can encounter pests, diseases, and common problems. Spider Mites: These tiny pests can be identified by the fine webs they weave on the plant. They cause yellowing or speckled leaves. Increase humidity around the plant and wash it with a strong stream of water.
How big does an artillery plant get?
Plant Type and Habit: The Artillery Plant is an evergreen perennial plant with a creeping habit. In its natural habitat, it often spreads over rocks and other surfaces, forming a lush carpet. Size: It generally grows to about 6-12 inches in height (15-30 cm) and can spread widely if given room, making it an excellent ground cover or pot filler.
Are artillery plants hardy?
Hardiness: It is hardy in USDA zones 11-12 and is typically grown as an annual or indoor plant in cooler climates. Uses: The Artillery Plant is used as an ornamental plant in rock gardens, terrariums, and as a ground cover in warm climates. It’s also popular as a houseplant due to its adaptability and ease of care.
What does an artillery plant look like?
The artillery species has plump leaves like a succulent. They are either green or variegated pink and white, one-eighth to one-half inch long, and “obovate,” or rounded and narrower at the base. The leaves are arranged in opposing pairs, like a fern frond. In nature, the species produces tiny pinkish flowers followed by brown fruits.
