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.
Rachis Blight. Also called petiole blight, this fungal disease has similar symptoms to the other fungal diseases that can afflict pygmy date palm trees and other palms. Rachis blight causes discolored streaks or lesions on the petioles of older fronds. The petiole is the stalk that connects a leaf to its stem.he fungus affects the tree's leaf blades and petioles and can later cause bud rot. Watch for signs of spots on the leaves of your palm; they begin small and yellow, then grow larger and become brown or black, and sometimes turn grey with a black area surrounding them. It also forms lesions on the petiole and rachis.
