Grow the best heirloom cosmos seeds for a beautiful garden
Cosmos bipinnatus, sometimes known as garden cosmos, is a half-hardy annual that may self-sow for several years. Allow the cheery demeanor of the heirloom cosmos, swaying in the breeze, to brighten your days. Heirloom cosmos blooms will appear 50 to 60 days after they are planted. Heirloom cosmos may grow to be two to six feet tall while in bloom and can become top-heavy. Plant in bunches or as a thick border along a fence line to avoid this problem. The leaves will intertwine, the colony will self-sustain, and you will surely enjoy their display. Try Eden Brothers' Heirloom Crazy for Cosmos Seed Mix if you can't pick a favorite!
Heirloom Cosmos are easy to grow!
Cosmos is a Greek word that means "balanced universe" or "harmony." It is a native of Mexico and one of the easiest flowers to grow. These beauties are appropriate for all zones and are ideal for beginning gardeners as well as youngsters!
Plant your heirloom cosmos seeds in the spring, while the earth is still soft enough to work. Heirloom cosmos like to be in the sun or partial shade. These flowers are very adaptive, thriving in situations ranging from ordinary to poor soil quality, as well as drought.
After the fear of frost has gone, scatter your heirloom cosmos seeds. Because seeds do not require direct sunshine to germinate, they can be covered with dirt to a depth of approximately 1/4 inch. For around 10 days, water your seeds, keeping the soil wet but not waterlogged. Germination might take as little as a few days or as long as two weeks.
Heirloom cosmos are easy to maintain
Heirloom cosmos require little to no maintenance once the seeds begin to grow. During hot, dry times, water your heirloom cosmos. If you want to boost flowering, you may use a general purpose fertilizer once or twice a season, although these blossoms are mostly self-sufficient. Make careful to deadhead old flowers as they droop if you want your cosmos plants to keep flowering throughout the summer. After blooming, trim heirloom cosmos down to 12 inches in warmer areas; they will bloom again in one to two months. Flower clumps should be divided every three years or so.
