金絲馬尾

一星期前去x觀園買了盆金絲馬尾,買時有兩盆可以揀,一盆多d芽仔,一盆蘭頭大d,我買了後者,葉太教我三日淋一次水,放於風處~

前日發現開始葉黃,葉子上有一點點黑色,請問應該怎麼處理?

太濕,開始爛根,
而葉面要殺菌

請問d蘭根點算?要點樣殺菌呀?add3icon

Your orchid is in a very ill condition. The composite is too wet and the root system is rotten, suffocated by water. Yellow color of the leave means the orchid is in a very bad shape.
Quickly take the whole plant out of the composite, wash the root and the whole plant, sterilize it with anti-fungal drug, put the poor plant in a shady with some air current area for a few days, say 4-5 days with misting occasionally. Then, put it in new composite again, better in clay pot, and keep the composite at the relatively dry, say watering every 7 days. Your plant takes a few months to recovery if not die. If you water the plant  every 3 days as instructed by Ms Yip, your cultivation area should be outdoor, not indoor. She does water her orchids every three days in Yuen Long.   I think she should sell this orchid in a good and healthy conditon as she is a honest orchid seller.

    Antifungal can be 百菌清、多菌靈、甲基托布津. All are in power form, and mildly toxic. Diluted the power as instructed with water. Put the whole plant in the solution for 10 minutes and put it in a good air current shady place to let it dry.
百菌清 is available in flower market. 百菌清、多菌靈、甲基托布津.are avaliable in Shenzhen.
Don't be frustrated if your orchid die as I expected. To cultivate Chinese orchid will face a lot failure in the beginning. It takes years years to master the skill. In fact, your orchid is a strong species and good for beginner.

我第一次種國蘭,預咗交學費,原來得好少根,重比我浸爛了~add8icon

情況不妙！！

Not too bad. But, it takes a bit skill to help it survive.
Cut away the rotten root that has already been black in color.
Sterilize it with antifugal for 10 minutes
Wrap the pseudobulb ( that has not rotten) with new wet sphagnum moss, spray with  蘭菌王 ( very important solution). Put the whole thing into a transparent plaster bag and fix it . Make some holes in the bag for respiration. Put it in bright area. Always keep the bag moist, not wet. Wait for a few months to see what happen.  
This may work. I have successfully rescued my Japanese orchid.

我浸咗百菌清,剪咗爛根,遲d換過過盆,希望可以救得返,多謝大家提點~

Keeping Chinese orchid a bit dry is safer than keeping it too wet. Air current is VERY important. Have you gone to the Chinese orchid green house? If you have been there, you will notice the cultivation environment.

Be aware the root system may not be adequate to supply water for the evaporation from its leaves in Hong kong weather in the coming weeks. Or you may be better to mist its leaves more frequently in the day time, or put a plaster bag with holes ( to increase humidity) covering the leaves when potted. You can find these informations from books.

我唔敢包住棵花呀,不過會試下噴多d水~

Don't let water staying on leaves over night.

唔怕,好通風~

芒骨出事

道人,佢d根已經爛晒喇~

只要蘭頭未收縮、乾水，還有一絲希望，不過我失敗左，教你唔到。
在書本上和網頁上都有提供方法，不仿一試。
