How to Plant Coleus:
If you want to start planting coleus seeds outdoor, then you have to plant them in autumn.
You can buy a packet of coleus seeds or mixed colours. Sprinkle the tiny seeds on the seedbed prepared by cocopeat. Now lightly cover it with some more potting mix. Now cover the tray with a plastic sheet and keep it in a warm spot until you can see the saplings.
After the winter, you have to transplant them to the bigger pot unless you don’t want to grow them on the ground. Keep it indoors or shade area before you repot the plant. The repotting before spring can damage the sapling. Make sure the saplings are sturdy enough to sustain the repotting stress and outdoor atmosphere.
You can also propagate coleus from cutting. It is the most popular and easiest way to propagate coleus.
You need to select a healthy stem that has 3-5 leaves. Take a sharp scissor and cut at least a 4-inch stem. Now remove a few leaves from the lower part. Take a little rooting hormone and dip the end of the stem in it.
You can plant it either in cocopeat or in water. If you place it in a pot, cover it with plastic to give a greenhouse effect Within a few days the roots will come. You have to re-pot it after 6 weeks.
You can take lots of cuttings at once so that you will have many plants.
The lighting condition plays an important role in the size and colour of the leaves. Morning sunlight is very good for this plant.
If the plant gets only morning sun and shade in the afternoon, you will get the best result as the plant will thrive. The darker leaves of coleus plants can handle more sunlight.
The shade spots are best for the plants that come with lighter colour leaves. It is very important to save the plant from heavy winds as it can break easily.
While repotting the grown-up coleus plant, make sure it is hardened well so that it can survive harsh weather and light.
Prepare the soil with normal garden mix and organic compost. Dig a little deep hole in the soil so that the root balls stay intact. If the roots are potbound, then tease them a little.
The base of the stem should be at the same level as the pot. Add the soil a little around the plant and push softly to remove the air pockets. Now water thoroughly.

Coleus does not have much demand for high-quality soil. The average garden soil will do good for it. However, make sure that the soil must be well-draining. You can add garden soil and organic compost in equal parts and blend them well to make the soil. There must be a potting hole in the planter.
Coleus is a tropical plant that thrives in warm areas. If the area is humid and hot, the coleus leaves will be vibrant in colour. They just need morning sun to make this plant sturdy.
If you stay in a dry and hot region, then you must keep it in a semi-shade. Cold temperature is not liked by coleus. It loves moisture in the soil but should not be soggy. Add lots of water only when the soil is well-draining.
To grow coleus vigorously, you need to add a good amount of fertilizer. You need to add chemical fertilizer which is high in nitrogen. You can also add liquid water-soluble fertilizer as well.
If you love organic compost, then add cow dung manure. If the particular fertilizer comes with any direction from the manufacturer then follow them. Add the fertilizer twice a year, preferably in March and November. All through the year, you can spray some liquid fertilizer as well.
The watering routine for coleus must be constant. The best soil for coleus must be moist every time, however, it should not be soggy.
If the soil is not wet all the time, then it is not a problem unless the dry period will be longer. The long dry period slows down the growth of the plant. If the plant starts to dry out, the leaves start to turn brown. If you notice the brown spot on the coleus leaf, then increase the watering.
Before watering check the soil. If the topsoil is dry, you are free to add water. If you stay in dry areas, try to add mulch to keep the moisture locked in the soil. However, make sure you should not add cedar mulch as they are harmful to coleus.
On hot and dry days, add water twice a day while keeping it outdoor.
For the best growth of the coleus plant, you have to pinch the flower so that the plant gets all the nutrients.
Start the pruning of the plant when the plant is about 6 inches long. For that, you have to pinch the growing tips of the plant. If you don’t want coleus seeds, then it is good to avoid flowering so that the plant uses all the energy in its leaves.
