Close the grill and cook for about 15â20 minutes, turning every 5 minutes or so. Check the corn ready when the husks start to get kernel-shaped char marks and pull away from the tip. If the kernels don't feel tender when poked with a fork, it's fine to leave the corn on until the husk chars black.
Orchids will lose their flowers after a certain time because they are spent and are producing new flowers on the stem. Also, some will lose flowers when they are too dry or have parasites.
Losing flowers is a normal event for most plants. Flowers bloom and run their course, then dry and fall from the plant. This makes way for new blooms. If your orchid is losing flowers, check the water and humidity conditions. Orchids like a high level of humidity and you can mist them lightly with a spray bottle. They usually need watering every couple of days, although in summer they may need daily watering.
