Why do potted flowers need regular cleaning?

The leaves of potted flowers at home are covered with dust, making otherwise beautiful flowers look "unkempt." Potted plants, especially foliage plants with broad leaves, tend to attract dust easily while being placed indoors. On one hand, dust blocks the stomata on the leaves, preventing the plants from absorbing moisture and oxygen from the air or releasing excess water from their bodies into the environment; on the other hand, dust also makes potted plants look dull and dusty, and after spraying water they become even more stained and unsightly. Therefore, in daily care, besides removing pests and treating diseases for potted plants, dust should also be removed promptly. Only in this way can the green natural space show its elegant style, and it is also greatly beneficial for purifying indoor air.

1. Timing for cleaning leaves

The time for cleaning leaves is in the morning, so that the leaves have sufficient time to dry before nightfall, avoiding the leaves being in a moist environment for a period of time due to lack of sunlight and lower temperatures at night.

2. Methods for cleaning leaves

Spraying method: Use the impact force of the water stream from a sprayer to wash the dust off the leaves.

Wiping method: Use a sponge or cotton cloth dipped in water to gently and repeatedly wipe the dust and dirt off the leaves.

Brushing method: Use a soft-bristled brush to brush the dust off the leaves.

Note: The first two methods are not suitable for cacti, succulents, and plants with fuzzy leaves. Once the leaves are wet, it is difficult for the moisture to evaporate, and even wiping the water off with a dry cloth cannot guarantee that they will dry within a certain period of time. Also, some flower buds that are sensitive to water, such as the flower buds in the leaf clusters of African daisies (Gerbera jamesonii) and the pseudobulbs in the leaf clusters of clivias (Clivia miniata), should not get wet, especially during the germination and bud-setting stages, as contact with water will affect the development of the flowers.

In addition, do not spray water directly onto the flowers. Flowers rot and wilt easily when they encounter water, and it can also lead to poor fertilization, affecting flowering and fruiting. Spraying water on the leaves of potted flowers such as pomegranate, crabapple, fuchsia, and crape myrtle can cause excessive growth of branches and leaves, so the latter two cleaning methods are recommended.
