How to propagate a sunflower
An introduction to the propagation and timing of planting sunflowers, let's get to know together the green plants and flower introductions on how to propagate sunflowers and the methods and timing.
Sunflowers, Portulaca perennial flowers, have many varieties and are a common and beautiful flower in summer and autumn. Many friends planted them in front of and behind their houses when they were young. Single-petal sunflowers have the ability to self-seed, growing wherever the seeds fall, germinating and flowering on their own without needing care. A little rain can make them grow, and the flowers of various colors are quite beautiful. Sunflower leaves vary, with round leaves, needle leaves, single-petal flowers, double-petal flowers, and rhizomatous ones, as well as annuals. Actually, the maintenance and propagation methods are quite similar, and both rhizomatous sunflowers and annual sunflowers grown from seeds can be propagated by cutting.
How to propagate sunflowers? Teach you a trick, roots in 7 days, flowers in 10 days, just right for autumn propagation.
Methods and specific steps for propagating sunflowers
1. Timing and selection of branches
Propagation can be done in spring, autumn, and summer. When propagating sunflowers, one or two long branches are sufficient. You can ask friends for some or buy some, as they are quite cheap outside, with several branches costing only one dollar. You can mix different colors of sunflowers in one pot. Fresher and plumper branches are easier to survive, and any branches that are not too dry or weak can be used.
2. Preparing potting soil and branches
Prepare a small flower pot and fill it with loose and breathable sandy soil. Mix in a little sand or vermiculite to prevent the soil from becoming too compact, allowing the branches to survive easily when planted in the soil. Cut a branch into short sections, about 3 to 4 centimeters long. To make the sunflowers more full and produce more flowers, plant the branches densely with a spacing of 2 centimeters. Let the cut ends of the branches dry first.
3. Specific propagation method
First, water the potting soil to make it moist, then insert the dried branches into the soil. The depth of insertion should be about 1 centimeter. After planting, spray some water to keep the soil moist. On the first day, you don't need to water. Place the pot in a shaded area with diffused light and water it the next day. After a week, the branches will start to grow roots, and then gradually expose them to sunlight for normal maintenance. Avoid direct sunlight as it is quite strong now. Place the pot in a shady and well-ventilated area, and make sure the soil does not accumulate water to prevent the branches from rotting before they have time to grow roots.
How to propagate sunflowers
Generally, roots start to grow within 5 or 6 days after propagation. If the branches had flower buds before, they will bloom on their own, and the growth is really fast. When new leaves or flower buds start to grow on the branches, you can water with diluted cake fertilizer, chicken manure fertilizer, or use slow-release fertilizer or phosphorus-potassium fertilizer to encourage more flowers and brighter colors.
When growing sunflowers in pots, expose them to more sunlight and fresh air, and pinch the tips to promote more branching. This will make the plant more full and able to bloom into a large flower ball. In autumn, plant a sunflower branch and grow a large pot within 30 days, blooming 100 flowers at once!
