Buying Guide
Choosing the right liquid fertilizer for your grass can seem overwhelming, but here are a few key things to consider:
- NPK Ratio: This refers to the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer. A balanced ratio like 16-4-8 is good for overall lawn health, while a higher nitrogen ratio may be better for promoting green growth.
- Grass Type: Different types of grass have different nutrient needs. Choose a fertilizer that is specifically formulated for your grass type.
- Soil Condition: Consider the condition of your soil. If your soil is compacted, you may want to use a liquid aerator in addition to fertilizer. If your soil is deficient in certain nutrients, choose a fertilizer that addresses those deficiencies.
- Application Method: Liquid fertilizers are typically applied with a hose-end sprayer or a pump sprayer. Choose a fertilizer that is easy to apply with your preferred method.
- Timing: The best time to fertilize your lawn is typically in the spring and fall. Avoid fertilizing during the hottest part of the summer, as this can stress your grass.
- Weed Control: If you also want to control weeds, consider a combination fertilizer and weed killer. However, be sure to use it carefully to avoid harming desirable plants.
