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.
While the foliage of orchids is mildly interesting, the reason most people buy orchids is to see them bloom. Once in bloom, orchid flowers can last for weeks. With the right care, you can get your orchid plant to bloom each year and enjoy those pretty flowers.
