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.
Watering and Fertilizing. After orchids stop flowering, they need a rest period before they resume flower production. Many orchids, such as Cattleya and Oncidium, have pseudobulbs, which are fleshy stems that store water and nutrients. During their post-flowering rest period, reduce watering.
