How to repot gardenias
This article provides a detailed explanation of the related topics about repotting gardenias, and will guide you through the following information.
How to repot gardenias, in order to promote their growth and development, it is necessary to repot them at the right time during cultivation. The general principle of repotting is to start with a small pot and then move to a larger pot, following the sequence and timing the repotting appropriately.
In the seedling stage, gardenias should first be planted in a 3-inch pot, and as the plant grows and develops, it can be gradually moved to a 5 to 6-inch pot, and finally to an 8 to 10-inch pot. The repotting is mainly based on the height of the plant and the fullness of the branches and leaves. Generally, the size of the pot should be proportional to the height of the plant. That is, the height of the plant should be greater than or equal to the diameter of the pot. Following the growth rate of gardenias, repotting every 1 to 2 years is sufficient, and finally, plant them in a large pot.
This method of gradually repotting according to the size of the plant can not only ensure the nutritional area of the plant but also allow the roots to develop fully, making the plant robust and symmetrical. If a large pot is used to cultivate the seedlings, it not only wastes pots and soil but also looks unbalanced with a small plant in a large pot, which affects the aesthetic appeal of the potted flowers.
Sometimes, in order to inhibit the growth of flowers, such as when cultivating potted tree trunks and ornamental flowers, the method of not repotting for a long time (some every 2 to 3 years) is often used, or the original pot size is maintained, combined with controlled fertilization and watering, to slow down the plant's growth and achieve the purpose of controlling its development.
When repotting, it is necessary to first cover the drainage hole at the bottom of the selected pot with pot shards to prevent the loss of soil. To ensure good drainage, place an appropriate amount of coarse sand or clean炉灰 (炉灰 = cinder) at the bottom of the pot, and then add the potting soil on top. During repotting, remove the original pot, remove some of the old soil around the roots, and then plant the plant in the center of the new pot, filling new soil around the roots.
To allow the roots to spread out, after filling the soil, gently lift the plant upwards and then press down on the soil surface of the pot with your hands, tapping the bottom of the pot against the ground to settle the soil. When filling the new soil, do not plant the plant too deep, maintaining the original depth. Planting too deep is not good for the growth of gardenias. Also, leave an inch of space at the top of the pot for watering. After repotting, water thoroughly and then place the pot in a shaded area. Especially for plants with severely damaged roots, it is necessary to wait until the roots have recovered and the leaves are growing normally before moving them to a semi-shaded area for management. The above is an introduction to how to repot gardenias.
