Light Requirements
The plant Pilea microphylla (L.) Liebm. thrives in bright indirect light. It is best to place the plant near a window with filtered light as direct sunlight can burn the leaves. If the light source is too dim, the plant will not grow as well and may appear leggy and spindly.
Temperature Requirements
The plant is adaptable to a wide range of temperatures but prefers temperatures between 60-75°F (16-24°C). Avoid exposing the plant to temperatures below 55°F (13°C) as it may result in leaf drop and stunted growth.
Soil Requirements
Pilea microphylla (L.) Liebm. prefers a well-draining soil with a pH range of 6.0-7.0. A good potting mix should contain a mixture of peat moss, perlite, and either sand or vermiculite. A soil mix that is too heavy and retains too much moisture can lead to root rot and other fungal diseases.
Cultivation
Pilea microphylla (also known as "Artillery Plant") thrives in bright, indirect light and grows best in well-draining soil. It is essential to keep the plant away from direct sunlight since leaves might burn or wilt quickly under the strong light.
Propagation is by stem cuttings, which can be rooted in any loose, well-draining medium. When the roots are well-formed, transfer the plant into a new pot.
Watering Needs
The Artillery Plant requires consistent watering. Water it when the topsoil feels dry to touch. Avoid over-watering, as waterlogging can lead to root rot.
Using room temperature water is best, as applying cold water can cause shock in the plant. In the case of tepid water, allow it to reach room temperature before watering.
Fertilization
Feed the plant with a balanced, water-soluble fertilizer once a month, diluted to half strength during the growing season (spring and summer). In winter, you can skip the feed altogether, or simply fertilize once every couple of months.
The Artillery Plant also requires micronutrients like iron. Using a fertilizer high in iron or the addition of chelated iron can nourish it and prevent yellowing of leaves.
Pruning
Artillery Plant doesn't require regular pruning. However, pruning can enhance its form and also encourage bushier growth. You can trim back any leggy stems, and pinch back any overgrown foliage to create a fuller form.
If the plant appears to have an unbalanced shape, it might be due to overgrowth on one side. Move the pot regularly to ensure all parts have adequate access to light and don't forget to prune regularly to promote even growth and maintain its shape.
Propagation Methods of Pilea microphylla
Pilea microphylla, commonly known as the artillery plant due to its unique way of dispersing its seeds, is a popular houseplant that is fairly easy to propagate. There are various methods that can be employed for propagating this plant, including:
Stem Cuttings
Stem cuttings is one of the simplest methods of propagating Pilea microphylla. Cut a stem along with a few leaves from the mother plant, making sure it is 4-6 inches long. Strip off the leaves from the lower end of the stem, leaving a few leaves on the top. Dip the cut end into rooting hormone to promote root growth. Then, insert the stem into a pot with moist soil, making sure the leaves are not touching the soil. Cover the pot with a clear plastic bag to create a mini greenhouse effect. Maintain the moisture level until roots start to form in two to three weeks.
Division
Another method of propagating Pilea microphylla is through division. This method is best for larger plants that have developed multiple rosettes. Carefully remove the plant from its pot and gently separate the rosettes from each other. Make sure that each rosette has roots attached to it. Repot each rosette in separate containers with moist soil and water them well. Keep them in moderate light, avoid direct sunlight and let the soil dry out slightly between watering.
Leaf Cuttings
Leaf cuttings can also be used for propagating Pilea microphylla. Select a healthy full-grown leaf from the mother plant and cut it off from the stem, making sure it has a portion of the petiole attached. Insert the petiole into moist soil, burying it about an inch deep. Keep the soil consistently moist for several weeks until a new plantlet forms. It is important to note that not all leaf cuttings will root, so you may have to take several cuttings to ensure success.
Propagation is a great way to increase your plant collection or share your favorite plants with others. With the proper techniques and care, propagating Pilea microphylla can be a fun and rewarding experience.
