The hydroponic method for gardenias
If you want to learn about the hydroponic method for gardenias and related gardening experience, let's get to know it together.
Hydroponic method for gardenias:
1. Gardenias are among the easiest flowers to hydroponically cultivate, and can be obtained through water insertion and root washing methods. The water insertion method can be carried out from April to October. Select several healthy branches free from diseases and pests, remove the basal leaves and dense branches, and directly insert them into water for cultivation, which easily takes root. The root washing method involves selecting strong, well-shaped soil-grown plants, cleaning the soil from the roots, and planting them in a hydroponic container, adding water to 2/3 of the root system, and within about 10 days, new water roots will sprout from the old roots and stem base.
2. In the early stages of hydroponics, change the water every 2-3 days, avoid direct sunlight, and frequently spray water on the leaves. When the water roots grow to 3 cm or more and the plant shows a strong growth, it should be moved to a bright area and switched to nutrient solution care, with a recommended 1/4 to 1/3 concentration of the garden test nutrient solution. The nutrient solution should be changed every 2-3 weeks, and only clear water needs to be added to compensate for the evaporated moisture. During the growing period, spray 0.05% ferrous sulfate solution on the leaves every 2 weeks, or add ferrous sulfate to the nutrient solution to keep the leaves green and shiny.
3. During the growing season, if the air is dry, spray water on the leaves and surrounding environment to maintain air humidity and wash off dust, keeping the leaves fresh and bright.
4. Gardenias thrive in a sunny and well-ventilated environment. In the midst of summer, they should be protected from direct sunlight and placed in a cool and ventilated area to prevent the leaves from turning yellow. In winter, they should be placed in a sunny area inside. It is reported that receiving more than 5 hours of sunlight a day can ensure the plant grows well with abundant flowers and leaves. However, the room temperature should not be too high in winter, as it may affect flowering the following year.
5. Gardenias have a strong branching ability, often forming three-way branches, which can lead to overlapping and tangled growth. It is important to promptly thin out the branches on the main stem and, in combination with shaping, remove crossing, parallel, overlapping, withered, and overly long branches to achieve a well-proportioned, appropriately long and short, and aesthetically pleasing plant shape. The above is an introduction to the hydroponic method for gardenias.
