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.

Aloe vera plants can turn brown due to sunburn, fungus or bacteria. The plant may be getting too much sunlight or the soil may be too wet. Sunburn will make aloe vera leaves turn dry and brown. Mushy brown leaves indicate a fungus, such as basal stem rot, which occurs in the cold and damp. Aloe rust thrives in high humidity and causes brown spots that spread. Bacterial soft rot develops in high humidity and wilts the leaves. To prevent browning, aloe vera plants should be allowed to dry thoroughly between watering.
