Storage After Arrival
Unpacked immediately upon arrival, ventilate if not immediately planted. Ideal storage temperatures are 50-60 degrees Fahrenheit
Planting in Zones 8 and warmer (Fall Planting)
Choose a location with 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. Plant bulbs 4-6in apart, 2-3in deep. Water after planting to encourage root development. Refrain from watering until leaves sprout (most likely will occur in spring).
Planting in Zones 7 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. Once the danger of a hard frost has passed, place the container in a location that receives full 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.
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. Following soaking instructions for outdoor landscape beds will give ranunculus a head start on growth.
Begin watering once plants begin to grow being careful not to allow the soil to become soggy. Fertilizing is not necessary. In warmer climates, wait until foliage dies back before completely removing it. In colder climates, ranunculus are annuals and bulbs will need to be replaced each year. On average, ranunculus begin to bloom 90 days after planting. Flowering typically lasts approximately 6 to 7 weeks for fall planted bulbs and 4 to 6 weeks for spring planted bulbs.
