Does coleus grow fast?

Coleus can be added to beds and borders for interest or grown in containers. They need fertile, well-draining soil and usually perform best in areas with partial shade, though many varieties can also tolerate sun. When growing coleus, keep in mind that these beauties can grow rapidly.

How quickly does coleus grow?

12-21 days
Coleus can benefit with bottom heat. Seedlings emerge in 12-21 days. As soon as seedlings emerge, provide plenty of light on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night.

How can I make my coleus grow faster?

Keep them indoors in a sunny window, and wait to move them outside until nighttime temperatures stay in the 50s. Coleus won’t grow any faster if you put them out early, and you could actually stunt their growth or they might die, even if temperatures stay above freezing.

Does coleus grow slowly?

They do need warmth; 70 degrees or higher will keep them happy. A few winters ago I had a collection of unhappy coleus plants. They did not die, but they grew very slowly, even with plenty of water and fertilizer. I had tried to grow them on a shelf under plant lights, but near the floor in a cool room.

How tall do coleus grow?

Coleus comes in three forms: upright, rounded and trailing. They range in height from 6 inches to 3.5 feet and grow 1 to 3 feet wide.

How long do coleus plants live for?

one year
While the lifespan of an average coleus plant is one year, you can prolong its life by pruning. Watch out for any small flower buds and prune it before the flower buds bloom. This is because once the plant starts producing flowers and seeds it will soon die.

Will coleus come back every year?

Coleus is a perennial, a tropical shrub, that is not hardy except in warm, frost-free zones. Cannas are reliably hardy in the ground outside from around Zone 7 and upward (warmer.) Here in the Chicagoland area, zone 5, Coleus is grown as an annual.

Why is my coleus growing so slow?

Diseases and pests can stunt the plant’s growth. Poor drainage is the biggest threat because it causes root rot. If the plant is in a pot, then repot it in a container with more drainage holes and in a mixture of peat and perlite. Pests that may attack coleus include mites and whiteflies.

How do I stop my coleus from blooming flowering?

Some Varieties Still Bloom Prematurely It may therefore be necessary to pinch (prune) these varieties at least once, as soon as you see the beginning of a flower spike. Pinching off coleus flowers is a snap: just squeeze the spike between the thumb and forefinger until it comes free. Or cut it off with pruning shears.

Why is my red coleus turning green?

Your coleus plant is most likely turning green because it isn’t getting enough light to maintain its original color. Coleus plants need lots of sunlight to keep their color, so if they aren’t getting enough, you’ll need to give it more to restore their beautiful hues.

How long does it take to grow coleus from seed?

Coleus are very easy to grow from seed and it’s fun to see the different colors of plants that will grow from one packet of seeds. If you plan to start them indoors, sow them 8 – 10 weeks before you want to plant outside. Germination takes 10 – 12 days if kept at 72 degrees F. They are also simple to propagate from cuttings.

Can Coleus grow in pots?

Coleus are low growing, so they look best at the front of a border, combined with other bedding plants, or in pot on a patio. If you’re growing coleus as a house plant, grow it in a bright spot that gets a little direct sun. You can buy coleus as ‘plug plants’ (young plants) in early spring.

Can You propagate coleus from cuttings?

You can propagate coleus by cuttings or seed. Cuttings will be identical to the parent plant, but newly seeded plants will be variable. Plants that are grown for propagation, however, generally do not look as good as ones grown exclusively for their foliage.

How much sun do coleus plants need?

Plants grown in containers indoors usually get plenty of light from indirect sun during the warmer (brighter) months but may need to be exposed to filtered sunlight during the winter. It doesn’t take much, but they do need some light. Coleus prefers a consistently moist, rich, loose soil.
