WHEN TO SET OUTSIDE
Two weeks after last spring frost, as coleus resents cool soil.
PLACEMENT & CULTIVATION
Coleus are often grown in containers that can be grouped with other shade lovers such as Begonia and Fuchsia to create instant gardens on the terrace. If planting in beds, make sure the soil is fertile and very well-drained. Many new coleus thrive in full sun, but if the leaves bleach try moving pots to afternoon shade. Coleus roots readily and can be re-planted slightly deeper than its previous depth in very well-drained soils, which will encourage fresh growth of roots as well as stems. Pinch back when planting to encourage a more bushy form and increase your supply, as coleus cuttings root easily in water.
About 1-2" a week. Keep evenly moist, allowing soil to dry slightly between waterings. Avoid saturated soils. Containerized plants may need more frequent watering.
Tolerates most soil pH levels.
Mix a time-released fertilizer into growing media or ground prior to planting. A regular application of water-soluble fertilizer is beneficial.
Diseases & Pests:
No major problems. Aphids can be controlled with several sprays of insecticidal soap, which smothers the insects.
