Self-planted flowers should pay attention to the prevention of diseases and insect pests

Flowers enter the autumn to prevent and cure the occurrence of diseases. At this time, 1% Bordeaux solution can be sprayed on the leaf surface and back of the leaf for 3 times to prevent diseases. The preparation method of 1% Bordeaux solution is as follows: 1 gram of copper sulfate, crushed and dissolved with hot water 50 ml; then 1 gram of quicklime, pulverized with a few drops of water, and then added 50 ml of water to filter the residue; pour the two solutions into the same container at the same time to stir well, that is, a blue transparent Bordeaux liquid all day.

Two methods of killing flowerpot insects and ants

When small flying insects appear in ① flowerpots, you can use three or four cotton cuttings (cotton sticks) to be fully dipped in dichlorvos, so as not to drip down, and then insert the end of the handle into the pot soil around the plant, and the flying insects can be eliminated.

When ants appear in ② flowerpots, cigarette butts and cut tobacco can be soaked in hot water for a day or two. When the water turns dark brown, part of the water will be sprinkled on the flower stems and leaves, and the rest will be diluted and poured into the flowerpot, and the ants can be eliminated.
