How to care for coleus
Coleus is easy to grow plants but there are plenty of factors that affect them. Take care of these factors for the healthy growth of coleus.
Most of the people has a question :
How do I make my coleus more colorful?.
The one sentence answers is:
You should plant or place (if you are growing in a pot) in the spot where they get morning sunlight and afternoon shade.
This is because:
In the afternoon the sunlight is much stronger than morning and will destroy the plant. So, it’s best to protect them with shade. The foliage of the plant gets directly affected by the light.
If you plant them in full sun the dark-purple spots will start appearing on the leaves. Whereas planting them in full shade fade in the leaves color.

The soil looks dry. Your aim should be to keep the soil moist but not wet. Overwatering the plant causes root rot.
Why is my coleus plant dying?
If you’re growing them in a pot then water once or twice in a day. Potted plants need more water as compared to ground plants especially in summer.
However never overwater them because it causes root rot that destroys the roots and leaves, the plant unable to absorb water and nutrients. Eventually, the plant died.
This plant likes hot temperatures ideally between 70-100 degrees F. They can tolerate hot temperatures but struggle in cold. Temperatures below 50 degrees F are not good for them.
Coleus Wasabi by
Serres Fortier To avoid this:
If you planted them in the pot it’s wise to bring the pot inside and place it in a warm spot.
Once the outside temperature exceeds 50 degrees F place them back. For ground planted you have to regrow them in the spring season.
Coleus prefers high humidity as the plant is habitat to tropical regions.

Coleus plants kept in the pot can be fed
liquid fertilizer in the growing season.
In the fall or winter fertilizing plants isn’t necessary as the growth of plants is minimal in these seasons.
If the plant is in the ground then fed slow release fertilizer is a good option.
To increase the abundance of leaves and vibrant foliage, choose a fertilizer that has a high
nitrogen level. Nitrogen is an important mineral in the plant’s growth. Pruning How do I make my coleus bushy?
Pruning is very important to keep the plant clean and bushy. Especially for coleus, the plant has a habit to get leggy. Prune them from time to time to encourage growth.
Here what you should do:
Take a sharp shear and sniff off spindly stems, ideally a short distance above the leaf node. This will result in the stem popping from the cut points.
You can also do pruning to make the plant neat or to stop from overgrowing.
However, this depends upon you whether you want to let them grow or bound in a certain size.
Should I cut the flowers off my coleus?
The coleus also bear flowers but they look faded in front of their bright and vibrant foliage. So, it’s wise to pluck the buds whenever you notice them in the plant.
Also, these fade flowers need the energy to grow which slows down the growth of the foliage.
By removing the plant’s buds you redirect the energy in the production of colorful leaves.
Coleus spread a lot, they need large space to spread but before you plant them in a larger area first grow them in a small pot.
They are easy to care for in pots, after they grow a few inches transplant them in the garden or plant bed.
Coleus Tricolor by

Rootbound will stop the plant’s growth. If you don’t want coleus to spread and remain in its current size then plant in a pot or container.
But their health will suffer and eventually, you have to give them more space to spread. So, after they grow a few inches in a pot transplant to a large area.
