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.
Yellow Leaves. There are many reasons that an olive tree may have yellow leaves and the course of action you take will depend upon the root cause. If there are just a few yellow leaves scattered throughout the canopy, it may be natural senescence.Since olive trees are not deciduous, they have continual leaf loss through the season.f the leaves are yellow with brown spots, your tree may be infected with Olive Peacock Spot. See below for Peacock Spot for treatment suggestions. If the leaves are turning brown and staying on the branches, your tree may be suffering from Verticillium wilt, which frequently results from overwatering or poor drainage.
