Gardenias, with their white flowers like snow and rich fragrance, have always been loved by people. However, it is not easy to successfully pot gardenias at home and make them thrive and bloom. This article will analyze the temperature needs of gardenias in detail and provide professional potted maintenance tips to help flower lovers better care for this beautiful plant.
1. The temperature requirements of gardenias.
Gardenias are native to warm and humid environments, so they have high temperature requirements. During the growing period, the optimum temperature for gardenias is 18 to 22. In this temperature range, gardenias will grow faster, with lush foliage and more delicate flowers.
However, when the gardenia enters the flowering stage, the demand for temperature changes. In order to promote bud differentiation and bud growth, the temperature needs to be maintained between 26 and 28. If the temperature is too low, it will affect the flower bud differentiation of gardenias, resulting in a decrease in the number of flowers or even no flowering. Therefore, during the flowering period of gardenias, special attention should be paid to maintaining a suitable temperature.
In winter, gardenias are less hardy and need to be moved indoors as early as possible for the winter. In general, if the indoor temperature is kept between 5 and 10, gardenias can survive the winter safely. However, it should be noted that if the temperature is below -10, it will bring frost damage to gardenias, frostbite plants. Therefore, when maintaining gardenias in winter, it is necessary to take thermal insulation measures.
In spring, although the temperature gradually warms up, it is not too early to move the gardenia indoors. Because the temperature changes greatly in spring, the temperature difference between morning and evening is large, and moving out of the room too early can easily cause gardenias to be damaged by cold. Gardenias can usually be moved outdoors for maintenance until late April, when the temperature has stabilized.
2. Maintenance skills of potted gardenias.
1.Choose the right potting soil.
The first step in planting potted gardenias is to choose the right potting soil. Gardenias prefer fertile, well-drained, acidic, light clay loam soils. When preparing potting soil, acidic substrates such as humus and peat soil can be added to improve the acidity and fertility of the soil. At the same time, in order to ensure the permeability and drainage of the soil, an appropriate amount of granular materials such as perlite or vermiculite can also be added to the potting soil.
2.Watering wisely.
Gardenias prefer moist environments, but they should not be overwatered. During the growing period, keep the soil moist but avoid standing water. In general, water thoroughly every time, but don't let the water flood the surface of the potting soil. In the summer high temperature, you can increase the number of watering appropriately; In winter, when the temperature is low, it is necessary to reduce the frequency of watering to avoid root rot.
3.Proper fertilization.
Gardenias need proper fertilization during their growth. You can choose organic fertilizer or compound fertilizer for fertilization. Fertilize at regular intervals to ensure the normal growth and flowering of gardenias. However, it should be noted that the principle of "thin fertilizer and diligent application" should be followed when fertilizing to avoid excessive concentration leading to "burning" of plants.
4.Trim properly.
Gardenias need proper pruning during their growth. Through pruning, diseased branches, weak branches and overly dense branches can be removed, and the shape of the tree can be maintained and the tree can be ventilated and light. At the same time, pruning can also promote the flower bud differentiation and flowering of gardenias. In general, pruning in spring and autumn is preferable.
5.Pest and disease control.
Potted gardenias should also pay attention to pest and disease control. Common diseases include yellowing, powdery mildew, etc.; Common insect pests include aphids, scale insects, etc. Once pests and diseases are found, control measures should be taken in time so as not to affect the growth and ornamental value of gardenias. Corresponding pesticides can be used for control, but pay attention to the method of use and concentration.
In summary, the temperature requirements of gardenias and potting maintenance techniques are essential for their growth and flowering. Only by mastering these knowledge and skills can you successfully pot beautiful gardenias at home.
