How To Care For Coleus Plant
It is an easy task when taking care of Coleus plants. All you need to do is ensure you meet its basic light, temperature, soil, and water requirements to ensure proper plant growth.
Coleus Light Requirement
The light requirement of the coleus plants varies with each variety of the plant. Varieties like the Coleus Wizard series can be planted and grown under full sun exposure.
However, most Coleus varieties grow well under full shade and that is why they are regarded as shade plants.
For the Coleus varieties that do require sunlight, prolonged exposure to direct sunlight can be harmful to the plant, so do ensure you regulate how much sun it takes in.
A great practice would be to grow the plant in a room next to an eastwards facing window, where it can soak up the early morning sun rays. During midday, relocate the plant to a full shaded area or room.
Coleus Water Requirement
You should aim for soil that is always kept moist, not soggy. Achieve this by letting the soil of the potted plant dry a little before the next watering session.
When growing coleus indoors, ensure you water it during the hot summer season twice a day. The same goes for Coleus care outdoors.
Cut back on watering during the winter season as it does go into dormancy and ensure that the water used is of room temperature and dechlorinated so as not to stress the plant’s delicate roots.
Coleus Soil Requirement
The soil type choice doesn’t matter when it comes to coleus plants, what matters is that the soil is rich, well-draining, and loose for the plant’s roots to breathe.\
It can be achieved through a proper mix of rich potting soil, mixed peat moss, mulch (don’t use cedar mulch as it is poisonous to the coleus plant), and some organic compost.
Keep the soil pH value in the range of neutral to a little acidic with a value between 6.5 to 7.0.
Coleus Temperature and Humidity Requirement
Coleus plants are tropical plants and as such require you to grow them in hot and humid environments.
Use a humidifier to provide humidity to the Coleus plant when growing them indoors and keep them away from vents or Air Conditioners.
Temperature levels should be left from 60 degrees Fahrenheit to as high as 80 degrees Fahrenheit. Anything lower than 50 degrees Fahrenheit could spell trouble for the plant coleus.
Coleus Fertilizer Requirement
Fertilizer should be used once a month if the soil used for planting coleus indoors is poor in nutrients.
Use a slow-release fertilizer or a liquid fertilizer that has been diluted and ensure you don’t overdo it.
First off, avoid propagation during a cold season or environment. It is best done during the summer or spring season and it can be done through stem cuttings.
Coleus Pruning requirement
Pruning should be done to keep the plant looking good and vibrant. With that being said, ensure that the tools being used for pruning are sterilized.
