Storage After Arrival
Unpacked immediately upon arrival, ventilate if not immediately planted. Ideal storage temperatures are 50-55 degrees Fahrenheit.
Soak corms in room-temperature water for 4-6 hours prior to planting. Leave the water running at a trickle to increase oxygenation during soaking. Allow plenty of room for bulb expansion.
Planting in Zones 7 and warmer (Fall Planting)
Choose a location that receives general crop rotation and has well-draining soil and that does not still puddle 5 or 6 hours after a hard rain. Adding organic matter of at least 2-3in will improve drainage. For fall planted anemones, it is recommended to remove plants from soil after harvest and plant a new/different crop in the same space for summer harvest. Plant bulbs 3-4in apart, 2-3in deep. Water after planting to encourage root development. Cover rows with frost cloth if temperatures drop below freezing.
Planting in Zones 6 and colder (Spring Planting)
Growing in Containers:
Fill a container with drainage holes with good-quality, well-draining potting mix. Leaving 3-4 inches between bulbs will allow plenty of room for growth. Plant about 2 inches deep. Water after planting to settle the soil around the corms and close any gaps. Once the danger of a hard frost has passed, place the container in a location that receives full to part sun all day.
Growing in Outdoor Landscape Beds:
About a month before last average frost, soak the bulbs 3-4 hours (but not more than 4 hours) in tepid water before planting outside in a well-drained location with full sun. Choose a location that receives general crop rotation and has well-draining soil that does not still puddle 5 or 6 hours after a hard rain. It is not recommended to use the same bed to grow anemones year after year without growing a new/different crop in the same location in between growing anemones.
Growing in Greenhouses:
Follow instructions for container growing. Ideal greenhouse temperatures are 45-48 degrees Fahrenheit at night and 58-65 degrees Fahrenheit during the day. Temperatures above 70 degrees Fahrenheit should be avoided as higher temperatures will affect growth and flower production.
Begin watering once plants begin to grow being careful not to allow the soil to become soggy. Fertilizer is not recommended during the first month in order to protect the young roots. After the first month, fertilize once or twice during the growing season using a general 7-3-7 NPK fertilizer. In warmer climates, wait until foliage dies back before completely removing it from the soil. In colder climates, anemone are annuals and bulbs will need to be replaced each year.
Using a 20-30% shade net is recommended. The netting helps to keep the soil cool, thus keeping the plants in flower production longer. The use of shading also will encourage the stems to elongate.
