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.
During the quiet period, the orchid grows new leaves and stores up energy for the blooming cycle. When it is ready, it will send up one or more spikes from which new blooms will sprout. For certain plants, the blooms may last up to eight weeks or more.
