Watermelon Pilea
The Watermelon Pilea (Pilea cadierei) is an attractive, evergreen perennial. A native of China, it has bright green, quilted leaves with silver markings. It grows up to 12 inches (30 cm)tall and spreads slowly. It has small clusters of white flowers that bloom in the spring. A well-established Watermelon Pilea is very easy to care for and makes a great addition to any indoor garden.
Watermelon Pilea should be watered regularly when the soil is dry to the touch. Aim to water the plant deeply but be sure to not overwater it. Always dump out any remaining water from the saucer, as this can cause fungal issues if the plant stands in water for too long. You may also want to mist the foliage to increase the humidity around the plant.
Watermelon Pilea prefers bright indirect light. Avoid a spot that gets too much direct sunlight, as it will cause the leaves to burn. Place it in a room with plenty of sunshine during the day or within a few feet of a window that will get at least four hours of bright light per day. You may also want to consider using LED bulbs to keep the light levels consistent throughout the day.
The Watermelon Pilea prefers to grow in temperatures between 60°F -75°F (16°C - 24°C). Do not allow temperatures to drop below this range, as this can cause damage to the plant. It can also handle warmer temperatures up to 80°F (27°C). However, avoid putting the plant in extremely hot spots, like near a heater or fire.
Watermelon Pilea prefers medium to high humidity. If the environment is too dry, the leaves will start to look scorched and limp. To increase humidity around the plant, use a pebble tray with water and add a humidifier in the same room. Alternatively, you can also mist the leaves regularly.
Watermelon Pilea prefers a light, well-draining soil. You can use a commercially prepared mix or create your own with equal parts peat moss, perlite, and vermiculite. To promote good drainage and aeration, add some extra perlite or sand into the mix. Make sure to water regularly and provide plenty of good drainage.
Watermelon Pilea grows best when fertilized once a month during the warmer months (spring and summer). Choose a fertilizer that is high in nitrogen, phosphorus, and potassium. Aim to use one that is suited for leafy plants. Organic options are also available and can be applied every two weeks instead.
Watermelon Pilea is susceptible to common pests like aphids, scale, spider mites, and mealybugs. If you see any of these pests on the plant, you should take action right away. You can start by gently brushing them off the leaves with a soft cloth or brush. For especially bad infestations, you may need to use insecticidal soap or neem oil. Be sure to follow the directions on the label and spray directly onto the affected areas.
As the Watermelon Pilea grows, it will need to be repotted. The best time to do this is in the spring when the plant is actively growing. Choose a pot with good drainage and make sure it is not too large for the root system. If the plant is root bound, it may need to be divided into several smaller plants. Be sure to use a light, well-draining potting mix.
To maintain a healthy shape and size, Watermelon Pilea should be pruned regularly. The best time to prune is in the spring or summer months. Pruning is especially important for variations of this plant that have cascading foliage. Use clean, sharp shears to cut away any dead or diseased leaves, as well as any stems that are too long. Avoid over pruning the plant, as this could damage the overall health of the plant.
Mulching the Watermelon Pilea helps to keep the soil moist and cool. You can use any type of organic mulch such as pine bark, straw, or wood chips. Make sure that the mulch is not too thick, as this can cause the soil to become waterlogged. Water the plant regular and maintain the mulch level.
The Watermelon Pilea can be propagated using stem cuttings. Start by taking a 6-8 inch cutting from a healthy stem. Dip the cut end in rooting hormone and place into a pot with moist, well-draining soil. Keep the cutting in a bright location and lightly mist the soil every few days. Once the roots have grown, the cutting can be transferred to its own pot.
Provide support for the Watermelon Pilea with a stake or trellis. This will help the plant to stay upright and prevent the stems from sagging or breaking due to the weight of the foliage. A few pieces of kite twine or bamboo sticks work perfectly for this purpose.
Watermelon Pilea will enter a dormancy period during winter. During this time, the plant will need less water and sunlight. Move the plant to a cooler spot in the house and try to keep the temperatures below 65°F (18°C). You can also reduce the amount of water given to the plant during this time.
Watermelon Pilea is toxic for both cats and dogs if ingested, so it should not be kept near animals. Symptoms of toxicity include drooling, vomiting, and difficulty swallowing. If you suspect your pet has eaten the plant, seek veterinary help immediately.
