Coleus Makes a Magnificent Houseplant
Although usually planted outdoors, with proper light and food, a coleus plant can make a great addition to your collection of house plants. Start with a beautiful, healthy coleus plant and care for it properly, and you will be rewarded for your efforts with a magnificent house plant.
Here's What You Will Need
- Small coleus plant
- Commercial potting soil
- Planter pot that drains
- Commercial house plant fertilizer (diluted)
I am going to assume you have just returned from a local nursery and have a young coleus seedling that is ready to be put in a nice, attractive planter.
How to Plant an Indoor Coleus
- First, use a light, well-draining potting soil (you can't go wrong with Miracle Gro®) in your pot. Put your little seedling in the pot and cover the roots with potting soil. At this point, you are looking at a rather dull-looking seedling wondering if I really know what I'm talking about. But, please don't underestimate this tiny little plant, which can grow and fill out a pot very nicely with some absolutely stunning foliage.
- The intensity of the light your plant receives on a regular basis will determine the intensity of the foliage color, so place your new plant in a south window for several hours of bright sunshine daily, and although they will adapt to somewhat lower temperatures, they will be at their best at around 75-80 degrees with moist (NOT soggy) soil. If you are fortunate enough to have a fluorescent grow light, by all means, use it for your coleus. The colors will become even more vibrant.
- Feed your coleus house plant once a month with a liquid houseplant fertilizer, but dilute it to about 40-50% water.
- Flower buds must be pinched off immediately because you don't want your coleus plant to go to seed. Once it goes to seed, it dies. Just keep pinching off the flower buds and your plant will thrive.
- If your plant becomes too leggy, pinching it off will help in that regard as well. A coleus plant is grown for its foliage and not for its flowers, so get them out of there quickly. When tips are pinched off, the plant diverts its energy to the sides making your plant full, bushy and gorgeous. Coleus plants are durable; cut them back almost to soil level if they start looking too leggy.

Questions & Answers
Question: How deep and far apart do I plant the Coleus seeds?
Answer: Coleus seeds barely need to be covered with potting soil, so just sow them on top of the soil, then just lightly put some soil over them. If you want your coleus to be thick, which I think is the best, sow them about a half an inch apart. If it looks like they are growing too close together, you can simply transplant some of them to another location, but I have always had good luck planting them pretty close together.

I believe you did the right thing. Coleus can make great houseplants, and in the spring (if you choose), you can put them back out in the yard. The only other alternative would have been to cut them back all the way to the ground and leave them to re-emerge in the spring.

I just took my colesus out of ground, It was getting to cold 40°. I put them in pots and bought them in the house.The purple one I have it seem like the leaves were closing up wilpping curling up don’t know if it’s in shock. But I’ve been keeping my eye on it. The green one some are curling up. I actually saved these plants from the store throwing them away. I bought them home during the Spring. When the fall and winter comes through I couldn’t stand to see my plants get frozen. Did I do the right thing by bringing them inside. Deb Love ❤️

Got a potted coleus from a florist; although it's gone through some trauma (there was a squirrel encounter prior to the plant being moved indoors), it's bounced back wonderfully. That said, it flowered indoors this year, and it's doing just fine--growing a little too vigorously, in fact, that I can't keep up with all the cuttings. So, flowering = death might depend on the variety?

There are so many different types of coleus, sometimes it's hard to choose just one. Thanks for reading.
