Every 14 days in Spring and Summer with nitrogen rich plant food.
In Spring, when they have been cut back, using peat-based or soil-based compost.
Sow seeds on surface of compost, indoors, in warmth and in light.
Propagate in Spring, from seeds or stem cuttings 2-3 inches long in water or in compost.
Coleus needs bright light to keep their leaf colour brilliant. Pinch out shoot tips regularly to encourage bushiness. Remove flower spikes to encourage more leaves. Cut back within 3 inches of the compost in Spring.
To test for watering, push a skewer, knitting needle or a pencil into the soil; if it comes out completely clean, the plant needs water.
In hot and in dry rooms, red spider mites can cause discolouration. Wash off heavy infestations of red spider mites under the water faucet. The two most common causes of failure are watering with hard water and letting the compost dry out.
