Solenostemon – Mt. Washington – Coleus – Solenostemon scutellarioides
Adapatable as House Plant
Dead-Heading Not Necessary
Many people feel that coleus look best before they flower. To keep foliage in top shape, pinch off the blooms as they appear if you wish.
Rules of Thumb for Overwintering Plants Indoors:
1. Choose only healthy plants
2. Bring Plants indoors before frost damages foliage
3. Treat for disease and insects before bringing plants indoors
4. Place in bright areas and add humidity using pebble trays or spray bottles
5. Be careful not to over water
6 When active growth starts in spring fertilize and prune as needed
7. Introduce your plants slowly to outdoor conditions in spring
Use in beds, borders and containers

Pinching and Growth Regulators
One to two pinches can be used to increase branching and for shaping. For small pot sizes this may not be necessary, larger pots will probably require pinching. Florel can increase branching and reduce flowering. Cycocel/B-Nine tank mix or Sumagic spray at 3-5 ppm will help control growth if needed. Growing on the dry-side . will help control growth resulting in fewer applications of PGR.s.
Pest and Disease Management
Diseases are uncommon if good growing practices are used. Good sanitation practices include keeping greenhouses clean at all times, eliminating weeds and debris, disinfecting equipment in greenhouses as often as possible and keeping hose ends off of the greenhouse floor. Good water management practices are critical for good, healthy plant growth.
-Establish in a warm environment, plants subject to chilling may be stunted. -Proper water management is needed. Do not allow severe dry-down or overly wet soils. However, growing on the dry side will help control growth resulting in lower PGR use.
