Coleus in open ground

Plectranthus scutellarioides (L.) R. Br.

Growing coleus in open ground requires maintaining a temperature regime that excludes frost and selecting lighting conditions that determine the brightness of leaf coloration.

In the reference 6 varieties crop Coleus, where this is mentioned in the description.

In temperate climates, coleus is cultivated as an obligate annual due to its lack of frost resistance. Planting in open ground is carried out only after the soil has warmed up consistently and the threat of late spring frosts has passed. To ensure the ornamental quality of the leaves, lighting control is required: excess sun can cause burns, while a lack of light leads to a loss of pattern contrast and shoot etiolation.

Agrotechnology in open ground includes regular pinching of the tips to form a bushy shape and prevent stems from becoming bare. Flower stalks must be removed, as flowering exhausts the plant and slows the growth of vegetative mass. The crop requires a consistently moist substrate, yet it is sensitive to waterlogging, which triggers the development of root and stem rots.
