Three Propagation Methods for Gardenias
This article introduces the three propagation methods for gardenias, which will surely help you. Let's learn about them together!
Many flower enthusiasts have been very successful in growing flowers, and their gardenias have even bloomed in abundance. However, they want to grow another pot but don't want to buy from the flower market. They want to try propagating gardenias themselves but don't know where to start. In fact, propagating gardenias is quite simple, and they have a strong vitality. As long as you know a bit about it, you can propagate successfully. This article is a summary of a flower enthusiast's experience with propagating gardenias through cutting, with three methods that are simple and hoping to be helpful to other flower enthusiasts.
Three Propagation Methods for Gardenias
1. -- Propagation by Cutting --
In mass production, southern regions often propagate in open-air beds from June to August, while northern regions do so indoors from October to November. Select healthy branches from the current or second year, with cuttings 8-10 cm long and having two leaves. Space them 5 cm apart in length and width for even rows, with a cutting depth of 2-3 cm. To promote root growth and improve survival rates, soak the lower ends of the cuttings in a solution of 40-100 mg/L indole acetic acid or naphthylacetic acid for 24 hours before planting. Maintain temperatures of 25-30°C and humidity above 80% for 3-5 weeks to root.
For cuttings that have survived, first plant them in small pots of 10 cm. When potting, ensure the roots are intact and spread out. Water daily, keeping the soil not too dry or too wet. After one year of growth, apply some dilute liquid fertilizer. When the plants reach 20 cm in height, you can pinch the tips to shape them into 3 or 4 branches, which will bloom the next year.
2. -- Layering Propagation --
The common method is high-stem layering. Select 2-year-old woody branches on the mother plant, make a ring-shaped cut, and fill a bamboo tube or plastic bag with moist moss, peat, or humus, then wrap it around the branch and tie it. Regularly water it to keep it moist. Under normal conditions, it can root in about one month. After rooting, it can be cut from the mother plant and potted to become a new plant.
3. -- Division Propagation --
Select plants with dense branches and robust growth, remove them from the pot, cut off a part of the plant from the roots, then pot it, and it becomes a new plant. Division is usually done in late autumn or early spring when the plant is dormant. Never perform division during the growing season.
The above are the three propagation methods for gardenias, including cutting, layering, and division. Have green plant enthusiasts understood these methods?
