How to treat southern blight in orchids? Flower Clinic shares a little trick for a cure

Some sources say: the conditions for southern blight to develop are that acidic soil favors the disease, the pH tolerance range is PH1.9-8.4, and the optimum is PH5.9. Precisely because of this, some orchid growers say southern blight can be treated with plant ash, and it is estimated that it can be cured in the early stage when the disease is not too severe. But my three pots of orchids were also initially covered around the pseudobulbs with plant ash, a thick layer, yet the several pots of orchids all died one after another. In spring I bought Lühui Lütaisu and planted it in several pots. They got southern blight, and slowly all died. This was the last pot to go. With the mindset of treating a dead horse as if it were alive, I poured laundry detergent water (about seven or eight grams of water, with about one gram of laundry detergent added) onto the base of the old pseudobulb. After a few days, small shoots emerged. I had not expected anything at first, but unexpectedly it kept getting more and more vigorous! After verifying on many forums, I found that many flower growers have had similar experiences. Laundry detergent does indeed have a certain therapeutic effect on southern blight! The above is my personal summary. I hope everyone will point out any mistakes! Article source: http://www.yuhuagu.com/
