The leaves of my french marigold are wilting, and the flower droops over due to its weight and skinny stem. (I have positioned the flower to lean against the glass this time).
This is the 2nd time already!
Why do the leaves keep wilting, a few at each time? Is it too little watering, air too dry or insufficient sunlight? I have tried to spot for pests and signs of infection... nothing!
I live in Singapore, the pot is 6 inch deep. I used to water it once every 7 days until the water runs out from the bottom. Right now I poke my finger in every 3 days and water it when it feels dry.
The pot is placed at a south west facing window (in my office around 25 degree celsius) which will get around 5 hours of sunlight behind a glass pane.
