For growers
- Typically plant 1 liner per quart or 2-3 liners for 6 to 8-inch (1 gallon) pots
- Plant in late summer and allow plants to bulk before vernalization. Overwinter outdoors or inside cold greenhouses. Allow plants to emerge and flower with naturally occurring spring temperatures. This method provides larger plants, more uniformity and more flowers.
- Alternatively, plant vernalized liners in March and April. Plants will not be as uniform, full or as floriferous as in bulked, overwintered crops.
- Media pH: 5.8 to 6.2; media EC: 1 to 1.5 mmhos/cm (saturated paste).
- Watch for: spider mites, thrips, botrytis.
- Allow plants to dry, but not wilt, between irrigations to prevent root and stem rot.
