Geodes can be found all over the world. Areas with the most geodes, however, tend to be deserts, volcanic ash beds, or areas with plentiful limestone. In the United States, for example, you can find plenty of geodes in California, Arizona, New Mexico, Utah, Nevada, Iowa, Missouri, Illinois, Indiana, Kentucky, and Ohio.
Water and Sunlight. Basil plants are low-maintenance and do not require much care. What little care they require, however, is important to keeping the herb healthy and the foliage supple. Too much water, too little water and lack of sun will turn the basil leaf tips brown and cause them to curl. Basil -- whether growing indoors or out -- requires at least six hours of full sun to keep it healthy.
Fungal Infection. Brown patch is a fungal infection of zoysia grass responsible for the presence of brown spots. Caused by the fungus Rhizoctonia solani, brown patch also occurs on other grasses like perennial rye and bluegrass, according to the University of Nebraska-Lincoln Extension.atural Control. Remove and destroy affected grass after mowing to prevent disease spread. When mowing grass, use a sharp mower blade instead of a dull one; dull blades don't make a clean cut and create wounds that fungi can easily invade.
