How much 10-10-10 fertilizer do you use on lawn bushes?

For lawn bushes, a general guideline is to apply 1 to 2 pounds of 10-10-10 fertilizer per 100 square feet of area. It's best to split this application into two sessions, applying half in early spring and the other half in late summer. Always follow the manufacturer's instructions and consider conducting a soil test for specific nutrient needs. Be cautious not to over-fertilize, as this can harm the plants and the environment.
