Potted flowers should be scientifically preserved according to different habits in autumn.

The management of flowers in autumn is very important, because everything begins to wither in autumn, and the conservation of potted flowers should be more careful. Watering and fertilization, temperature, light, pruning, cold protection and warmth of potted flowers should not be careless, and scientific maintenance should be carried out according to the different habits of potted flowers. the specific methods are introduced as follows:

Watering and fertilizing

The climate in autumn is cool, the temperature difference between day and night is large, and the water evaporation of basin soil is slow. Daily watering should determine the watering times and quantity according to the climate characteristics and the growth habits of potted flowers.

Generally, it can be watered once a day, if too much watering, the plant is prone to rot, resulting in leaf yellow shedding; under watering, there will be drooping leaves and weak plant growth. Watering is appropriate to keep the basin soil wet and dry.

In autumn, most potted flowers are in a period of exuberance, usually topdressing and ripening dilute liquid fertilizer every 10 days. Potted flowers that bloom in autumn, such as dahlias, chrysanthemums, cyclamen and magnolia that bloom in winter, can be applied more nitrogen, phosphorus and potassium fertilizer to promote their blooming and leafy. Pine and cypress, iron tree, brown bamboo, hanging orchid and asparagus should be fertilized 1 to 2 times, which can not only keep the leaves green, but also increase the ability to protect against the cold after winter. Generally speaking, before Frosts Descent, flowers that need to spend the winter in the open air should stop topdressing to avoid freezing damage.

Reasonable pruning

Potted flowers sprout a lot of buds in autumn, which should not be allowed to develop, and weak branches should be cut off properly so as not to consume nutrients. For the retained branches, leaves should be left to pick buds, plants with strong growth should be cut heavily, and those with weak growth should be cut lightly; potted flowers pregnant with flower buds in autumn, such as plum blossom, wax plum, rhododendron, etc., should not be heavy-cut, but can be treated with coring. Reasonable pruning is beneficial for the plant to accumulate nutrients and lay a foundation for future growth. It can promote the aging of branches and enhance the ability of cold resistance.

Autumn combined with pruning, cutting flowers and trees, the survival rate is also higher, such as cutting rose and so on.

Prevent disease and dispel insects

Autumn is a good time to control plant diseases and insect pests. Before potted flowers enter the house, medicine can be sprayed to prevent overwintering diseases and insect pests. If diseases and insect pests have been found, targeted and thorough treatment should be taken.

Enter the room in due course

The time for potted flowers to enter the house should be different according to different flowers. Milan, jasmine, asparagus and other warm flowers can enter the room early; kumquat, plum blossoms and other slightly cold-resistant or more cold-resistant flowers can enter the room late.

In addition to cold-resistant flowers such as pine, cypress and holly that survive the winter in the open air, and flowers such as red leaves and yellow clover that enjoy leaves after frost, it is better for most flowers to enter the house in front of Frosts Descent.

Protect against cold and keep warm

After Cold Dew, if the light is insufficient, the temperature is improper, and the fertilizer and water are out of balance, it is easy to weaken the plant. Potted flowers that are afraid of Cold Dew and are not tolerant to low temperatures, such as Milan, Fusang, poinsettia, Michelia, etc., are extremely prone to frostbite, so they should be maintained under the eaves with plenty of sunshine and leeward. When the temperature drops to 5 ℃, move into the sunny place indoors.
