What to do if the Brazilian iron withers

Replace the potting soil

When growing ornamental plants at home, pots and soil are very important. New pots and new soil can be replaced according to the different growth stages of different plants. This will enable the plants to grow better. If the pots are not changed for a long time, the roots in the pots will grow into a clump, seriously affecting the plant's nutrient absorption.

Therefore, in order to avoid this situation, it is necessary to change the pot and soil. When changing the soil, the soil must be disinfected and the use of compound soil fertilizers without sufficient ascites should be avoided.

Fungi cause the blight of Brazilian ironwood

Fusarium oxysporum is a fungus that harms plant growth. Due to environmental influences and improper breeding, it may cause explosive growth and plant wilt caused by Fusarium oxysporum. You should use 6000 times potassium permanganate solvent to spray as rooting water, and then water it twice after the plant comes back to life to prevent it.

After a plant becomes sick, the diseased plants and residual plants should be destroyed in a timely manner to prevent the spread of the bacteria and cause a disaster.

Pythium is also an important cause of wilt of Brazilian ironwood. When Pythium occurs, 800 times of 25% metalaxyl should be used for spraying, and the spray should be thorough.
