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.
* Most orchids can tolerate more sunlight if there is a good air movement to keep the leaves cool. Remember brighter sunny weather often means higher temperatures. Good air movement is critical. * Orchids that need direct sun, prefer dappled sunlight as they get in nature. In the northern hemisphere, several hours of dappled morning sunlight during on all but the hottest days of summer should be fine. Late afternoon sun, which is often combined with high temperatures, should be avoided.
