Hydroponic culture frees the flowers from the pests and diseases of the soil, but it still suffers from environmental pests and diseases. The fungi, bacteria, and viruses in the air can still be immersed in the stems and leaves of water-cultivated flowers, causing them to undergo varying degrees of disease. Aphids and scale insects can float into the room with the wind and land on hydroponic flowers to suck juice. The moth lays eggs on flowers, hatches into larvae, and also jujubes the tender leaves and stem tips of flowers. Washing the roots into water-cultivated flowers will also carry fungi, bacteria, viruses, eggs, larvae, etc. If you do not examine them carefully, you will leave hidden troubles.
Due to the particularity of the furnishings environment, hydroponic flowers should not use chemical pesticides to kill insects, nor can they be sterilized with large doses of fungicides if pests and diseases occur. Although these drugs can play a role in insecticidal sterilization, they also cause pollution to the environment. Therefore, the possible pests and diseases in hydroponic flowers should be mainly prevention.
When selecting hydroponic flowers, choose plants that are as robust, lush, and free from pests and diseases as possible. If pests are found during the conservation process, they can be caught by hand or rinsed with tap water. The hydroponic flowers are not very infectious, and only a few leaves have brown lesions, dead necrosis, or irregular wet spot-like lesions, which are formed by fungal or bacterial infections. Remove it and do not spread it. Water-cultured flowers with disjointed and rotted roots can be treated with plant renewal methods. At the lower end of the stem section, branches that are still intact are cut at the lower end and inserted into clear water. After a period of maintenance and management, new roots can be developed. Become an independent plant.
