Is it okay to prune chrysanthemums in September?
Do you know about these? Let's delve into the content regarding chrysanthemums, such as whether it is okay to prune them in September. Let's find out together.
As soon as September arrives, some enthusiasts ask if it's okay to prune chrysanthemums in September. This is mainly because after a period of rapid growth, the plants have become quite tall, and the height needs to be controlled. Whether chrysanthemums can be pruned in September depends on the type and the region.
For small chrysanthemums that bloom around November, you can lightly prune them now to maintain a good plant shape. Early bloomers, garden chrysanthemums, and summer chrysanthemums have already formed buds and do not need to be pruned.
Counting the days, some chrysanthemums are almost at the White Dew season, and large chrysanthemums are about to form buds. The main tasks are to remove excess lateral branches, maintain the terminal bud, prevent pests, straighten the stems, and avoid lodging.
As the temperature drops, chrysanthemums enter a rapid growth period. Generally, water-soluble fertilizers, at a dilution of 1000-1500 times, should be applied every five to seven days, with the specific concentration adjusted accordingly until the buds show color.
Currently, the main pests include aphids, cotton bollworms, and larvae of leaf-rolling moths. Pay attention to daily observations and manually remove them. Aphids can be treated with suitable chemicals, or a solution of laundry detergent can also be effective. As the temperature starts to cool down, many pests emerge. Small balconies can opt to hang mosquito repellent coils to drive away pests.
The above is all about whether it is okay to prune chrysanthemums in September. Have green plant enthusiasts understood this?
