Some plants, like liriope and azaleas, can collect fertilizer granules in the whorls of their leaves and injury may result. If the soil in a lawn is compacted, aerate the soil, then fertilize. Watering the fertilizer in afterwards will reduce the chances for injuring any groundcover or lawn grasses.
Does fertilizer improve the quality of soil?
If the soil lacks minerals, then fertilizer can improve its quality. The primary nutrients or minerals in soil required for growth are nitrogen (N), phosphorus (P), and potassium (K).
