    How to Care for Cosmos flower

    • In order to prolong flowering, you should deadhead the plants (prune off dead/faded flowers). This speeds up flower development and aids branching.
    • Because some of these plants can grow really tall, staking may be necessary. Offer them protection from strong winds, encourage balanced branching by pinching out (aka pruning) central shoots or stem tips, or stake them. Growing them against a fence can also provide the necessary support.
    • Water regularly until plants are established or if it is unusually dry. Make sure you don’t over-water cosmos; over-watering and over-fertilization can lead to plants with fewer flowers. Cosmos can tolerate dry soil, even in a hot, arid, sunbaked spot.
    • Cosmos beds may become weedy due to the fact that they self-seed, so remember to remove flowers before they go to seed or to thin seedlings in the spring.

    Propagating cosmos flower

    Cosmos plants readily self-seed. It’s best to propagate these plants after the threat of frost is gone. Although sowing seeds is the best and easiest way to propagate this plant, you can also propagate via stem cutting. When you take stem trimmings, it stimulates more leaf and flower growth. Besides seed, stem cutting is the best way to propagate this plant. Here’s how you do it:

    You’ll need sterile pruning shears or scissors and a pot of sterile, well-draining potting soil.
    Fill a small 3-inch container with moistened potting soil. Using a pencil tip, push straight down in the soil about 1 to 2 inches deep, making a shallow hole.

    Look for a cosmos shoot that has 3 to 5 leaf nodes on the stem. Cut under the last leaf node. At the last leaf node, carefully cut off the leaves, leaving the node intact for new growth.

    Bury the cut tip of the stem in the pencil-made hole. Make sure that the last leaf node is above the soil line. Push down the soil around the stem, compacting the soil to keep the stem upright and in place.
    Water generously and keep moist. You should notice new leaf growth within three weeks. If you do, you can gently pull the root ball out of the container, Transplant the root ball to its new location.

    How to grow cosmos from seeds

    Start seeds indoors, four to six weeks before the last frost. Or if you can sow cosmos outdoors directly in the garden well after the threat of frost is gone. Cosmos grow very quickly but can be killed by a late frost, so don’t rush it. They typically germinate in 7 to 21 days at 75 degrees Fahrenheit, followed by flowering in about 50 to 60 days.

    Loosen the soil to a depth of 8 inches. Plant the seeds and cover them with 1/4 inch of fine soil. Seed packets usually recommend precise spacing, such as at 2-foot intervals, or you can scatter the seeds and let the plants support each other as they grow. You can always thin them out later, moving the extra plants to another part of the garden.

    How to get cosmos to bloom

    Cosmos plants need full sun to bloom. Even the hint of shade, can restrict flowering. Also, to encourage more blooms, you need to deadhead the old blooms. For faster blooms, prune between the main stem and a leaf. The lower you cut in the stem, the longer it takes to grow more flowers.

    Harvesting

    Harvesting Seeds and Cut Flowers :

    To harvest more seeds, remember to leave a few flowers on the plant because they will self-seed.
    You can cut the flowers off anytime after blooming, but it’s best to pick some right when the petals have opened.

    If you cut the blossoms when they first open, they’ll last more than a week in water. Simply strip off the lower leaves and put them in a vase.
