How to grow Garden Cosmos 'Red dazzler'
Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Red dazzler is thought of as half hardy, so it will require protection in frosts and low temperatures. Try to keep the ph of your soil between the range of 6.6 and 7.8 as Red dazzler likes to be in weakly acidic soil - weakly alkaline soil.
Growing Red dazzler from seed
Sow at a depth of approx. 0.25 inches (0.64 cm) and aim for a distance of at least 0.98 inches (2.5 cm) between Garden Cosmos plants. Soil temperature should be kept higher than 20°C / 68°F to ensure good germination.
Transplanting Red dazzler
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Red dazzler is a half hardy plant.
Harvesting Red dazzler
The botanical epithet is from the Latin bipinnatus meaning “staunch” or “like two small wings”.
