Care of the Dark Mystery Pilea Plant
Dark Mystery pilea plant grows well in well-draining soil, indirect sunlight, and a moderate temperature. Let’s take a look at the basic requirements of the Pilea Dark Mystery plant.
Soil
Dark Mystery Pilea plant grows the best in all-purpose, well-aerated, and draining soil. To fortify it, you can add organic matter like coco coir, vermiculite, perlite, or compost.
Since the pilea plant is native to rainy tropical and subtropical regions, you will need to create a similar environment for it. To do this, simply add two inches of mulch to the base of the pot to help retain moisture. Also, ensure that the soil is well-draining. To ensure water does not swamp the roots of the plant, you can add a handful of perlite or vermiculite .
Dark Mystery pilea grows well in acidic to neutral soil with a pH between 6 to 7.5.
Temperature
Dark Mystery pilea plants well in moderately warm temperatures, ranging from 62°F and 85°F during the day and 50°F and 65°F during the night. Like most houseplants, this plant does not do well in colder temperatures, so do not position it before the air conditioner, in a room with a cold draft, or outside in the frost.
Light
Contrary to what its name may suggest, Dark Mystery pilea plant thrives in bright places and should be put in a suitable spot where it can get about eight hours of light. However, make sure you do not put it in direct sunlight as it can burn the leaves. Place the plant in a south-facing room within three feet of a window for sunny conditions. If the plant is getting full direct sun, place a sun shade on the window to protect it from the harsh rays of the sun.
Avoid putting the pilea Dark Mystery pilea plant in north-facing rooms as too little light is not good for the plant and will result in drooping leaves.
Water
Dark Mystery pilea has a relatively high water requirement. Make sure the soil does not completely dry out before you water it. To determine when it is time to water, poke your finger 1 inch into the soil to check if the top soil is dry. If it is, you should give it about a cup of water every seven to nine days if it is placed in a 5-inch pot. If the pot is larger, adjust the water amount as necessary.
Adding perlite to the soil can also help it retain the right amount of moisture while ensuring aeration.
Humidity
Dark Mystery pilea plants enjoy moderate to high humid conditions. As such, it is important for you to maintain 40 to 60 percent humidity by watering the plant regularly and not letting the soil dry out. On the days when you do not water the pilea plant, it is important to spray around the stem so that the water can be absorbed by the roots.
If you live in a place with dry conditions, then it is a good idea to install a humidifier that adds moisture to the air.
Fertilizer
The potting mix you use to plant the pilea Dark Mystery pilea plant will have adequate nutrients to sustain the plant. By the time you need to replenish the nutrients, your plant will already have doubled in size and will require a larger pot anyway.
To fertilize the soil, you can add a half-strength liquid houseplant fertilizer by diluting it in the same amount of water, once in the summer and once in the spring season, to the growing pilea plant. You should not add fertilizer in the winter as the plant is dormant during the season and needs its rest.
Potting, Pruning, and Propagation of the Pilea Dark Mystery Plant
Let’s take a look at the potting, pruning, and method of propagation for the Dark Mystery pilea plant.
Potting
The pilea Dark Mystery plant should be placed in small pots about four to five inches wide. The soil should be all-purpose and rich, and you can add peat moss, perlite, and organic matter to enrich it.
Place the plant in the middle of the pot and pack the earth around it lightly. Make sure the plant is watered well and is placed where it gets plenty of natural indirect light.
After a year, your plant will have doubled in size and will need to be repotted.
Pruning
Even though the Dark Mystery pilea plant does not require a lot of maintenance, it can get unkempt over time. To keep your plant neat and tidy, you should neatly prune the plant’s dry and damaged lower leaves by snipping off the leaf close to the main stem.
You should also thin the pilea plant’s foliage when it becomes thick and scraggly as this will ensure better circulation of the air and will improve the plant’s aesthetics. Do not remove more than 20 percent of the plant at a time.
When pruning the plant, you should also take care to sterilize the shears as that can prevent the spread of infections.
