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.
Provide enough moisture. In order for buds to produce flowers, they need to be watered regularly. Orchids when budding tend to lose a lot of moisture and although buds are made up of mostly water, it will not be sufficient for the whole plant. Monitor the moisture content of your plant.
