Cosmos Flowers Seed (Cosmos Dwarf Sensation Mix )1000 Seed - Covers 200 Sq.ft. Direct sow in after the danger of frost has passed. Seedlings are not winter hardy. Sow in full sun...A true sunshine worshiper. Prefers well drained soils so avoid heavy clay areas. DO NOT FERTILIZE. Rich, fertile soils tend to produce unusually tall, lanky plants with few blooms. Plants become top heavy and fall over. Cosmos can be a great cut flower with a vase life of 5-7 days. Harvest the blooms in the early morning hours, and select stems with flowers that have just opened. Remove the leaves below the water line. Generally trouble free, seldom falling prey to disease or insects, and they do not mind being crowded. Cosmos (Cosmos Bipinnatus Mix) - One of the most popular annuals to grow from flower seeds, Cosmos Bipinnatus, provide such an amazing display of color for the little amount of work they require. This Cosmos mix has colors of pink, white, and maroon. What a fabulous sight to see this mix of Cosmos colors in a field or meadow! They naturalize very easily and are attractive to bees and butterflies. Sometimes the name Mexican Aster is used for Cosmos flowers. Cosmos Bipinnatus seeds look like miniature pine needles, so they are easy to work with and sow. They don't mind over crowding, so scattering the Cosmos seeds over freshly tilled bare soil is a fast and easy way to sow the flower seeds. After scattering the seeds, compress the flower seeds into the dirt and cover lightly with no more than 1/16 inch of soil. Keep the soil moist, and very shortly fast-growing, fern-leaved plants will shoot up. When the seedlings are 4 - 12 inches tall, they transplant very well. Dig them up and move them wherever you would like them to grow. When Cosmos Mexican Aster flower seed is planted in the early spring, it is not uncommon to have a second planting in summer. By mid-summer there may be an abundance of dried seed pods. You can encourage re-bloom simply by cutting the plants back to 12 - 18 inches high. Allow those flower seed pods to open and drop their flower seeds onto the soil. Cosmos plants are liberal self-sowers, so helping them along just means there will be more blooms!
