Answer: When hostas turn brown it is usually due to lack of soil moisture. These plants need an evenly moist soil, and the more sun they receive the more moisture they need. A little morning sun is fine, a little dappled light all day is fine, but more than that and it may just be too sunny for them as well. Fertilizing would not help, in fact it would add more stress on the plants by pressuring them to grow. YOur local professionally trained garden center staff should be able to help you analyze the site and see if it is suited to hostas.
