How to Grow Coleus Indoors

Growing coleus indoors is very easy if you follow a few basic steps.

Choose a healthy coleus plant or take a cutting and root it in water.
Place the plant in a well-lit spot with indirect sunlight.
Use a pot with proper drainage to avoid root rot.
Water regularly and maintain a warm indoor environment.

Watering Tips for Coleus Plant Indoors

Watering is the most important part of coleus care.

Water your indoor coleus when the topsoil feels dry.
Avoid overwatering, which can cause yellow leaves and root rot.
In winter, reduce watering frequency as the plant’s growth slows down.

Best Soil for Coleus in Pots

Coleus thrives in loose, well-draining, and nutrient-rich soil.

Mix garden soil with compost and cocopeat or perlite for aeration.
Avoid heavy clay or soggy soil that retains water.
Use a pot with drainage holes to prevent waterlogging.

Coleus Plant Sunlight Requirements

Light plays a big role in keeping coleus leaves vibrant.

Indoors, place your coleus near a window with filtered or indirect sunlight.
Morning sun is okay, but protect from harsh afternoon rays.
If light is too low, the plant may grow leggy and lose color.

Coleus Plant Temperature and Humidity Needs

Being a tropical plant, coleus loves warmth and moisture.

Ideal temperature: 18°C to 30°C.
Don’t expose to cold drafts or sudden temperature drops.
Mist occasionally or use a humidifier during dry seasons to maintain humidity.

Fertilizer for Coleus Indoor Plants

Feeding your coleus encourages strong growth and rich colors.

Use a balanced liquid fertilizer (like 10-10-10) every 2 to 3 weeks.
Apply during spring and summer growing months.
Avoid over-fertilizing, which may lead to weak stems or faded leaves.
