Cultivation Methods and Precautions for Small Chrysanthemums
An article sharing the cultivation methods and precautions for small chrysanthemums, related to green plants. Here are the details introduced by the editor for netizens.
Cultivation Methods and Precautions for Small Chrysanthemums
Small chrysanthemums are best planted in sandy loam soil rich in humus, with good drainage and fertility. During growth, they need plenty of sunlight, but should avoid strong sunlight around noon and cold during winter frosts. The watering principle is to water thoroughly when dry, avoiding waterlogging. During the vigorous growth period, fertilize with a compound fertilizer dissolved in water every 2-3 weeks, and stop fertilizing during flowering.
Small chrysanthemums are easy to care for. They have high ornamental value with bright colors and a faint fragrance, making them very suitable for pot cultivation at home. They are also adaptable, easy to propagate, and grow quickly, making them ideal for beginners.
Techniques for Pot Cultivation of Chrysanthemums
1. Potting Soil Selection
Chrysanthemums prefer loose, humus-rich acidic sandy soil. The general soil mixture is a ratio of humus soil, garden soil, river sand, and organic fertilizer of 2:2:1:0.5. This mixture ensures good aeration and drainage. Avoid using garden soil that has previously been used to grow chrysanthemums. After preparing the soil, if possible, use dolomitic lime to disinfect before use.
2. Potting and Planting
Planting chrysanthemums should be done on a sunny day. Place coarse sand or small stones at the bottom of the pot to increase aeration, then cover with the prepared and disinfected potting soil. After planting the chrysanthemum, press the soil surface firmly with your hands and cover the top with a layer of fine sand to reduce the growth of small flying insects in the pot.
Cultivation Methods for Small Chrysanthemums
1. Soil
Small chrysanthemums have a wide adaptability to soil and are best planted in sandy loam soil rich in humus, with good drainage and fertility. Note that the soil should be disinfected before use.
2. Sunlight
Small chrysanthemums thrive in a sunny environment and do not tolerate shade. They require plenty of sunlight to promote growth and flowering, but should avoid strong sunlight around noon and cold during winter frosts.
3. Temperature
The optimal temperature for the growth of small chrysanthemums is 18-22 degrees Celsius, and for flowering is 10-25 degrees Celsius. If the temperature drops below 5 degrees, they will be frostbitten. Therefore, when external temperatures are too low, they need to be moved indoors or insulated. If temperatures exceed 25 degrees, the plant will have larger leaves, longer flower stems, and fewer flowers.
4. Watering
Watering small chrysanthemums should be adjusted according to seasonal changes. In summer, water twice a day, early morning and evening, to keep the potting soil moist. In winter, water less frequently, about once every 3 days.
5. Fertilizing
Fertilizing small chrysanthemums should follow a regular pattern, generally using a compound fertilizer dissolved in water every 2-3 weeks. Note that fertilizing should stop after the flowers bloom in February, and a dilute nitrogen fertilizer can be applied again after the flowers fade in May.
Precautions for Caring for Small Chrysanthemums
1. Watering Principle
The watering principle for small chrysanthemums is to water thoroughly when dry. If too much water is accidentally added, promptly remove the excess water to prevent root rot and repot with new soil. After watering, it is best to place the plant in a well-ventilated area to reduce waterlogging.
2. Diseases and Pests
Common diseases of small chrysanthemums include sclerotinia, gray mold, (T-J) disease, and downy mildew, which can be controlled by spraying 50% wettable powder of carbendazim and metalaxyl. Diseased branches and leaves should be cut off promptly to avoid affecting the growth of healthy plants.
The comprehensive explanation of the cultivation methods and precautions for small chrysanthemums provided above is hoped to be a reference to help solve your green plant-related issues.
