The stems and leaves of green pineapple are blackened and rotten. It is easy to get new potted plants by this treatment.

If you find that the bottom of the stem is black and the leaves begin to blacken slowly, some friends think that the green pineapple can no longer live and throw it away. What would you do if it were you?

The branches and leaves of green pineapple turn black, generally because of watering too hard, the roots of the soil can not breathe normally for a long time, which will eventually cause rotten roots and rotten stems, and even the leaves will continue to blacken. Of course, it is also partly due to frostbite caused by low temperature. Green pineapple is a tropical foliage plant. The lowest maintenance temperature should be kept above five degrees Celsius. When the temperature is too low, the stems and leaves are also easy to cause frostbite.

Once it is found that the bottom of the branches of the green pineapple is black, it must be pulled up in time, and the old soil will be thrown away directly, which contains fungal diseases. The next step is to deal with the rotten roots of green pineapple, and if the branches and leaves turn black, they should be cut off in time.

After cutting off all the blackened parts, soak in the germicidal solution, which can be soaked in carbendazim solution or potassium permanganate solution for 5 minutes or 10 minutes before being replanted.

The remaining healthy stems and leaves can be re-cut in the soil, or you can choose hydroponic rooting, and the leaves at the bottom should be removed to prevent the leaves from being soaked in water or buried in the soil.

Re-use new potted soil and new flowerpot cultivation, the old flowerpot must be sterilized before use, otherwise it is easy to cause secondary infection.

Re-cutting green turnip pot, should be raised in a ventilated environment, bright light, or weak scattered light, avoid being raised in the sun or exposure environment, otherwise it will be easy to wilt, serious will cause drying up.

After that, it is necessary to keep the soil moist, but not too humid. in addition, it is necessary to spray water regularly to maintain a certain amount of air humidity. another key is to pay attention to ventilation and avoid being kept in a sultry space, otherwise it is also easy to cause fungal diseases.

Maintain green pineapple in summer and avoid putting it directly in the air outlet of the air conditioner, otherwise the branches and leaves will wilt easily.

When the temperature is higher in summer, the green pineapple will consume more water, so you should replenish the water regularly, as long as you avoid stagnant water in the basin or support basin. The leaves should also be cleaned regularly to prevent them from accumulating too much dust and affecting photosynthesis.

It is not difficult to feed the green pineapple. Some friends are afraid that the green pineapple will freeze to death in winter and lower the temperature by less than 10 degrees. It is necessary to move it to a warm place indoors for maintenance. The lowest temperature had better be kept above 7 degrees. If frostbite occurs, the frostbitten part must be cut off directly, and then move to a place where the temperature is higher than 10 degrees, but do not put it next to the heating where the temperature is too high, otherwise the branches and leaves will rot easily.

If it is found that there are yellow spots on the leaves of green pineapple, it is likely to be infected with fungal diseases. in addition to pruning diseased leaves, fungicides should be sprayed regularly, which can be sprayed with chlorothalonil or methyl topiramate once every 5 days. spray about 3 times in a row can be completely removed. If you just cut off the leaves without spraying, it is easy to cause secondary infection.
