Can double petal sunflowers be propagated by sowing?
The editor answers for netizens whether double petal sunflowers can be propagated by sowing and provides an introduction to the correct propagation methods of green plants and flowers. Let's take a look together!
Can double petal sunflowers be propagated by sowing? It depends on whether they are super double-petaled. The more petals there are, the more serious the degeneration of the pistil, the lower the pollination success rate, and the harder it is to produce seeds. Most of the double petal sunflower seeds on the market are actually imitated by single or semi-double sunflower seeds.
Double petal sunflowers (pine leaf peony) are mostly propagated by stem cutting. The stems (branches) are very easy to root, with the bottom of the stem shallowly buried in soil about 3CM deep, watered thoroughly (the soil should have good drainage, not too fertile, common nutrient soil is fine, the key is to ensure soil aeration and avoid continuous moisture or waterlogging).
Double petal sunflowers are perennial herbaceous plants with poor condition in winter low temperatures. The stems and leaves on the ground will wither and stop growing and flowering (excessive low temperatures can cause frostbite, it is recommended to maintain a minimum temperature of 4 degrees for potted care), and when spring comes, they will sprout again and grow new branches and flowers.
Can double petal sunflowers be propagated by sowing?
The branches of double petal sunflowers are relatively robust and full.
Double petal sunflowers are fleshy-rooted plants, suitable for online shopping for their stems for propagation by cutting. Their leaves are very easy to fall off, and even if the stems received do not have leaves, they can easily survive, without affecting subsequent growth, mainly relying on the nutrients in the stems to root. For stems with flower buds, the flower buds can be removed (it's not a big deal if the flower buds are not removed).
If friends at home have these double petal sunflowers and want to propagate a few plants, it is even simpler. Wait for the stems of the sunflowers to grow longer, cut off several sections with each section being over 9 centimeters long, remove the bottom leaves, and then insert them into the soil.
Subsequent management is also very simple. Insert the stems of double petal sunflowers into the soil, water thoroughly, and keep them in a semi-shaded place. Ensure the environment is well-ventilated and well-lit, the soil is not overly moist, and there is no waterlogging. Then, wait for the soil to completely dry out before adding water. It usually takes about 10-15 days for the stems to root and sprout.
