How Do You Take Care Of Rainbow Coleus?

Coleus Rainbow Mixture is a magnificent foliage display plant that produces a wide variety of vivid colors and may reach a height and spread of 12-15 inches if left unchecked.

Pinch out the variety to foster a bushy habit. Ideally suited to a shaded spot in the border or pots, but equally at home as an interior potted plant.

Grows well in partial to complete shade on wet, well-drained soil that has been amended with organic matter. It is quite easy to germinate and thrive on.


Coleus Rainbow Mixture prefers intense light each day in a sunny area, but it may also grow in partial shade.

Its leaves may burn if exposed to excessive light, however this is uncommon in natural light. If not provided with sufficient light, its leaves may droop.


Coleus loves soil that is regularly wet, rich, and well-draining. Amend the soil with compost or another organic material prior to planting.

Any good-quality potting mix will suffice for potted plants. Ensure that the container you purchase has drainage holes.


Coleus plants thrive in persistently damp but not saturated soil. While the soil should not be wet at all times, prolonged periods of drought can inhibit plant development and cause the leaves to turn brown around the margins.

Allow the soil to dry somewhat between waterings and water only until the top inch of soil feels completely dry to the touch.

Temperature and Humidity

Coleus is a tropical plant that thrives in hot, humid climates. In temperate climes, even the slightest suggestion of cold will kill the plants.

When temps fall into the 50s, bring plants indoors or shelter them. Take propagation cuttings before the weather becomes chilly.

Maintain a safe distance between indoor plants and air conditioner vents and other chilly locations. In arid locations, plants require some humidity, which may be provided by a humidifier or a bathroom atmosphere.

Wait until the weather reaches 70 degrees Fahrenheit or above before bringing potted plants outside in the spring.


You may not need to feed coleus plants at all if you have good soil. If your soil is deficient, amend it using a balanced slow-release fertilizer. If you fertilize sparingly, you’ll get the greatest color from your coleus leaves.

What is Rainbow Mix coleus?

Coleus, also known as Painted Leaves, is a tender perennial that is grown for its colorful foliage.

Rainbow Mix has solid or bi-colored leaves in shades of red, green, yellow, maroon and pink. Coleus is ideal for shaded gardens and makes an excellent container plant for indoor or outdoor use.

Does Coleus Rainbow Mixture likes pruning?

Pinch out the developing tips of plants when they reach approximately 6 inches in height to create full, bushy plants. Pinch underneath the flower buds to direct the plant’s energy toward leaves rather than flowers and seeds.

Without pruning, plants become leggy and lose their attractive form and thick foliage. If the plants stay leggy, they may require additional sunlight.

This is particularly prevalent with indoor plants throughout the winter, so provide them with some more sunlight or, if required, artificial light.

How do you propagate Coleus Rainbow Mixture?

Coleus Rainbow Mixture plants may be grown simply by rooting stem cuttings.

Cut a 4- to 6-inch long stem tip with a sharp shearing scissor. Ensure that the incision is made directly under a leaf node along the stem. Remove all leaves from the cutting’s lower half.

Dip the stem end in a rooting hormone compound and then plant it in a moist potting mix, covering the exposed leaf nodes with earth.

Put the container in a plastic bag, ensuring that the plastic does not come into contact with the cutting.

Place the covered cutting in a sunny, warm position for two to three weeks, or until new roots form.

Remove the plastic from the young plant and continue growing it in a bright, warm location.

Certain unique cultivars may be reluctant to root; thus, take numerous cuttings to guarantee that you have enough healthy plants.

How to Grow Coleus Rainbow Mixture from seeds?

Although the majority of modern coleus types sold in shops are hybrids that are nearly usually produced from cuttings potted up for nursery sale, seeds of many species are still available.

If you intend to grow coleus in an outdoor garden, start seeds inside around eight to ten weeks before the last frost date in your area.

Coleus is a simple plant to cultivate from seed. The seeds may take up to 21 days to germinate, so be patient.

To germinate, Coleus seeds require light and temperature. Sow seeds on top of moist soil or seed starting mix, gently pressing them into the soil and leaving them unprotected.

To begin, place the pots on a heating pad, seed-starting mat, or comfortable window sill and maintain a temperature range of 70oF to 75oF.

Once seedlings sprout, three to four weeks of warm weather will aid in their development into fully formed plants.

Sprinkle the small seeds lightly over a tray filled with potting mix and lightly cover with dirt.

Cover the tray with plastic wrap and place it in a sunny, warm position for approximately two weeks, or until seedlings grow.

Remove the plastic and continue growing the seedlings while maintaining a wet soil environment.

When the seedlings develop two sets of true leaves, carefully transplant them into their own pots and continue developing them until the seedlings are ready for outdoor planting. Prior to putting seedlings in the garden, ensure that they have been hardened off.

What are the Common Pests & Plant Diseases that affects Coleus Rainbow Mixture?

This Coleus is a favorite of groundhogs and juvenile rabbits. If you cover your plants early enough in the season, these pests will often move on to other plants by mid-summer.

Severe infestations of mealybugs, aphids, spider mites, whiteflies, and slugs should be avoided.

Unless the temperature becomes chilly and rainy, Coleus is rarely troubled by illnesses. If this occurs, look for symptoms of fungal illnesses such as mildew.

Assure that the plant has enough drainage, since stagnant water might result in fungal root and stem rot.

Is Coleus Rainbow Mixture poisonous?

Coleus is harmful to cats, dogs, and horses, according to the American Society for the Prevention of Cruelty to Animals (ASPCA). Therefore, keep pets away from coleus plants in your yard or on your property.

Coleus is classified as a non-poisonous plant for humans by the National Capital Poison Center. Individuals with sensitive skin, on the other hand, may experience skin discomfort after handling a plant.

How much water does Coleus Rainbow Mixture need?

Coleus is a thirsty plant that requires frequent watering to maintain a wet but not waterlogged soil. During the growth season, from April to September, water only until the top 1″ (2.5 cm) of the potting mix is completely dry.

The frequency with which you should water your plant is determined by the ambient temperature, the kind of pot, and the stage of growth of the plant.

During the winter, you should continue to water coleus, but on a less frequent basis. As a general rule, water only after the top layer of soil has dried out.

To water coleus, use room temperature water. Fill the pot halfway with water so that it drains out the bottom. Return the container to its saucer only when the water has ceased to drip.

Proper watering is critical for disease prevention, including root rot and fungal or bacterial concerns in the soil.

Allow a day or two for the water to settle before using it. This allows chlorine to dissipate and protects your tropical plant from injury.

Avoid squirting water on the leaves, since this might result in persistent wet stains.

How do you take cuttings from Coleus Rainbow Mixture?

You can multiply your plants as much as you want. Plants propagated from cuttings will retain their original color and leaf design.

The pruned 2–4-inch tips can be utilized to establish new plants.

Remove the lowest leaves from these cuttings and tilt the base of the stem.

Immerse the cutting at least an inch into a growth media such as soil, sand, peatmoss, vermiculite, or even water.

Maintain a moist medium (or fresh water) but do not add fertilizer. In a few days, roots will begin to form. These cuttings can be rooted directly in a shady garden bed over the summer.

After two to three weeks, carefully pull a cutting upward. If the young plant resists your tug, it has a strong root system and is suitable for transplantation.

Does Coleus Rainbow Mixture need repotting?

When your plant becomes rootbound and outgrows its present container, repotting is essential. Repotting coleus is best done in the spring, when the plants begin to develop strongly.

Choose a container that is 1″ to 2″ (2.5 – 5 cm) bigger than the existing container and has lots of drainage holes. Repot in a similar-sized container if you don’t want your plant to grow larger.

Replacing coleus is simple. How to repot a tropical houseplant is as follows:

Pluck the coleus gently from its pot and brush off any extra soil.

Untangle the roots if required and inspect for signs of root rot or damage—prune as necessary.

Fill a fresh container halfway with an acceptable potting mix.

Transfer your healthy coleus to a new location, ensuring that it is planted at the same height as it was previously.

Fill the pot halfway with potting mix, firm the soil around the stems, and thoroughly water.

Keep out of direct sunlight and in a bright place.

What type of soil do Coleus Rainbow Mixture needs?

Coleus should be planted in a well-draining potting soil that enables sufficient oxygen to flow and maintains the plant’s health.

The ideal soil will have a combination of peat moss, perlite, and pine bark. This sort of potting media retains precisely the right amount of moisture without turning mushy.

The same maintenance instructions apply when growing coleus in your yard—ensure that the soil drains rapidly.

When selecting soil for your container, a commercial all-purpose potting mix should suffice. For other plants, such as succulents, the soil may be too acidic or too rich for coleus.

When it comes to container soil, the most crucial piece of advice is to ensure that it drains adequately.

Does Coleus Rainbow Mixture need humidity?

Most tropical plants, like the coleus, require high amounts of humidity to survive. The average household is insufficiently humid for moisture-loving coleus plants.

The most effective method of maintaining correct humidity levels is to either place the pot on a pebble tray or to use an air humidifier.

Apart from putting a humidifier in the room, grouping several houseplant pots together can also help increase humidity.

Crispy leaves with brown tips indicate that the indoor air is too dry for your coleus.

Unlike other tropical houseplants that require daily watering, coleus leaves do not require spritzing. Watermarks on the velvety leaves might detract from the plant’s look.
