What are the propagation methods of sunflowers
Life knowledge series: This article introduces the propagation methods of sunflowers and the green plant flower planting techniques that describe the cultivation of sunflowers. Here is a comprehensive introduction.
How to propagate sunflowers through cutting?
Sunflowers, Portulaca perennial flowering plants, have many species and are a common and beautiful flower in summer and autumn. Many friends have planted them in front of and behind their houses when they were young. Single-petal sunflowers have the ability of self-sowing. They grow wherever the seeds fall and bloom on their own without needing care. A little rain can make them grow, and the flowers of various colors are quite beautiful. Sunflower leaves are different, with round leaves, needle leaves, single-petal flowers, double-petal flowers, and rhizomatous ones, as well as annual ones. In fact, the maintenance and propagation methods are almost the same for rhizomatous sunflowers and annual sunflowers grown from seeds, both can be propagated through cuttings.
How to propagate sunflowers? Teach you a trick, roots in 7 days, flowers in 10 days, just right for autumn propagation.
Sunflower cutting method and specific cutting steps
1. Cutting time and stem selection
Cutting can be done in spring, autumn, and summer. When propagating sunflowers, one or two long sunflower stems are sufficient. You can ask friends for some or buy some, as several stems can be purchased for just one dollar outside. You can mix different flower colors in one pot. Fresher and plumper stems are more likely to survive, as long as they are not too dry and weak.
2. Prepare potting soil and stems
Prepare a small flower pot and fill it with loose and breathable sandy soil. Mix in a little sand or vermiculite to prevent soil compaction. Cut the stems into small sections, about 3 to 4 centimeters long, to make the sunflower plants bushier and produce more flowers. The density of cutting should be high, with a spacing of 2 centimeters. Let the cut ends of the stems dry first.
3. Specific cutting method
First, moisten the potting soil, then insert the dried stems into the soil. The stems should be planted about 1 centimeter deep. After planting, spray water to keep the soil moist. You don't need to water on the first day. Place the pot in a shaded area with scattered light and water again the next day. After a week, the stems will start to grow roots and gradually be exposed to sunlight for normal maintenance. Avoid direct sunlight, as the light is quite strong now. Place the pot in a cool and well-ventilated area and prevent waterlogging to avoid stem rot before roots grow.
What are the propagation methods of sunflowers
Generally, roots start to grow within 5 or 6 days after cutting. If the stems had flower buds before, they will bloom on their own. The growth is really fast. When new leaves or flower buds start to grow on the stems, you can water with diluted cake fertilizer, chicken manure fertilizer, or use slow-release fertilizer or phosphorus-potassium fertilizer to encourage more flowering and vibrant colors.
