What to do about the green aphids on roses
Roses are common ornamental flowers in homes. Plants in unsuitable growing conditions or improperly cared for are easily affected by pests, such as aphids. Roses are generally prone to aphid infestations during the spring. If there are a few green aphids on the plant's leaves, the affected leaves can be cut off, and the plant can be sprayed with chili water, camphor oil, or cigarette butt water to eliminate the aphids. If there are many green aphids on the rose plant, the affected branches and leaves can be cut off, and the plant can be sprayed with chemical pesticides such as dinotefuran and pymetrozine.
If there is an outbreak of aphids during the spring and there are a few green aphids on the rose leaves, the affected leaves and branches can be cut off and burned, and the plant can be sprayed with diluted camphor oil or chili water.
If there are many aphids on the rose, after cutting off the affected branches and leaves, the plant can be sprayed with chemical pesticides such as Nupasak, Pyrethrin, dinotefuran, and pymetrozine to eliminate the pests. Generally, the plant can be sprayed with pesticides once every 7-10 days, and after 3-4 consecutive days of spraying, the effect of the pesticide can be seen. Using different pesticides alternately can enhance the pest control effect.
Roses thrive in warm, well-ventilated environments. If the plant is in a humid and dark environment for an extended period, its growth may deteriorate, making it susceptible to pests. During maintenance, it is necessary to open windows frequently to keep the indoor air circulating. During its growing period, the plant should be provided with adequate light and fertilization to promote growth and enhance its resistance.
During the spring and summer, to prevent the plant from being affected by pests, it is advisable to spray fungicides regularly. Generally, the plant can be sprayed with a fungicide once every 20-30 days to effectively prevent diseases and pests. During maintenance, the plant should also be provided with adequate light to enable photosynthesis, which can promote the growth of branches, leaves, and flowers.
The above introduction on dealing with green aphids on roses is hoped to provide flower enthusiasts with some knowledge about flowers.
