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.
They can lose leaves and flowers when too dry, or it is insufficiently humid, or strong light is drying them out. They prefer to be kept moist and can be watered every other day, depending on the kind of orchid. Distilled water is preferable because orchids can be susceptible to pollutants.
