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 Problems. Fungal problems (like root rot) can also cause leaves to turn brown. In addition you can be feeding your plant well and it wonât be able to absorb the nutrition if its root system is compromised. If the roots of your plant are turning brown or black and feel mushy or slimy this is a sign of root rot.ry moving your anthurium to a slightly less sunny location or try to filter out a portion of the sunlight with a thin, filmy curtain. Or you can have the window next to your anthurium plant tinted. If you use a curtain, remember that it shouldnât block out all of the sunlight. It should only block a portion of it.
