The simple method of flower propagation: water insertion
The editor will answer your questions about the knowledge of hydroponic flowers, the simple method of flower propagation - water insertion, and will share detailed content next.
Artificial propagation methods for flowers include seeds, spores, and vegetative propagation, among which cutting is the main method. The advantages of the cutting propagation method are numerous, the main ones being: simple method, abundant materials, large output of seedlings, fast seedling growth, early flowering, and the ability to maintain the inherent characteristics of the original variety. In addition to these advantages, water insertion propagation has the following benefits: sufficient water, high humidity on the water surface, good ventilation, small temperature difference between day and night, which is conducive to root growth, simple management, hygienic, time-saving, and labor-saving.
1 Water Insertion Method
1.1 Use containers with a larger diameter such as wide-mouth bottles, beakers, canned food bottles, and water cups, first fill them with water, then cut branches about 10 centimeters long, containing 2 to 4 healthy nodes free of diseases and pests, and insert them into the water. During the rooting process, it is important to keep the water clean and change the water every 2 days if necessary. Moreover, for branches that secrete sap from the wound, it is better to let them dry in a shaded place before inserting them.
1.2 Use large basins, glass tanks, ponds, or other water surfaces for insertion. First, find one or several pieces of foam board and make round holes about 3 centimeters thick at a certain row spacing and plant spacing. Then insert the cut branches one by one into the holes and float them on the water surface. Similarly, it is important to keep the water clean during the rooting process. Easy-to-root flowers can grow roots in about 15 days, while difficult-to-root flowers can grow roots after 1 to 2 months. When the roots grow to 3 centimeters, they can be taken out and planted in flower pots. Place the newly potted flowers in a shaded place, and after 7 to 10 days of acclimatization, a new flower has been successfully propagated. The method of water insertion rooting is suitable for many flowers.
