How to propagate double petal sunflowers
If you want to know how double petal sunflowers propagate and the introduction of green plants and flowers in terms of sowing and cutting propagation of sunflowers, it can certainly help you. Let's learn about it together!
Can double petal sunflowers be propagated by sowing? It depends on whether they are super double petal ones. The more petals there are, the more serious the degeneration of the pistil, the lower the success rate of pollination, and the harder it is to produce seeds. Most of the double petal sunflower seeds on the market are imitated by single or semi-double sunflower seeds.
Double petal sunflowers (pine leaf peony) are mostly propagated by stem cuttings. The stems (branches) are easy to root, with the bottom of the stem shallowly buried in the soil about 3CM, and watered thoroughly (the soil should have good drainage, and the soil used for cutting should not have too much fertility, ordinary nutrient soil is fine, the key is to ensure soil ventilation and avoid continuous soil moisture or waterlogging).
Double petal sunflowers are perennial herbaceous plants with rhizomes. In winter, they become poor in low temperature conditions, the stems and leaves on the ground wither and stop growing and flowering (excessive low temperature can cause frostbite, it is recommended to keep the minimum temperature of potted plants above 4 degrees), and in the spring of the following year, they will sprout again and grow new branches and flowers.

The branches of double petal sunflowers are relatively strong and full
Double petal sunflowers are fleshy-rooted plants, suitable for online shopping for their stems for cutting propagation. Their leaves are easy to fall off, and even if the received stems have no leaves, they are easy to survive and do not affect subsequent growth. They mainly rely on the nutrients in the stems to root. For stems with flower buds, the flower buds can be removed (it doesn't matter much if the flower buds are not removed).
If friends at home have double petal sunflowers and want to propagate a few plants, it's even simpler. Wait for the stems of the sunflowers to grow longer, cut off a few segments, each segment should be more than 9 centimeters long, remove the leaves at the bottom, and then cuttings can be planted in the soil.
Subsequent management is also very simple. After the stems of double petal sunflowers are cut and planted in the soil, water thoroughly and keep them in a semi-shaded place. The environment should be kept ventilated and well-lit, the soil should not be too moist, and no waterlogging. Then, wait for the soil to completely dry out before supplementing water. It usually takes about 10~15 days to root and sprout.
