The Battle of Fertilizers: Liquid vs. Granular

Your lawn has endured the scorching heat and freezing cold, and now it’s time to give it a boost of nutrition. But with so many options available at your local garden center, choosing the right fertilizer can be overwhelming. Don’t worry, though! Our guide to liquid vs. granular fertilizer will help you make an informed decision and provide the best care for your lawn.

Liquid Fertilizer: A Quick Fix

Liquid fertilizer is a concentrated solution that you dilute with water and spray onto your lawn. Some liquid fertilizers come in a dry, water-soluble form that you have to dissolve. These fertilizers are quick-release, which means they provide immediate nutrients to your grass. However, because the nutrients are absorbed quickly, liquid fertilizer needs to be applied more frequently than granular fertilizer.

Liquid fertilizers usually come in convenient bottles that can be attached to a garden hose. Some popular options include High Nitrogen Liquid Lawn Food Fertilizer, AgroThrive All Purpose Organic Liquid Fertilizer, and Garden Lawn Liquid Spray.

Granular Fertilizer: Slow and Steady

Granular fertilizer, on the other hand, is dry and comes in the form of pellets. Most granular fertilizers are controlled-release, which means they release nutrients slowly over a period of six to eight weeks. However, there are also quick-release options available.

You can find granular fertilizer in various-sized bags or bottles at physical stores or online. Some recommended options are Scotts Turf Builder Weed & Feed3, Scotts Turf Builder Triple Action, and Milorganite All-Purpose Eco-Friendly Slow-Release Fertilizer.

Controlled-Release vs. Quick-Release Fertilizer

When choosing a fertilizer, it’s important to consider whether you want a controlled-release or quick-release option. Controlled-release fertilizers provide nutrients gradually over time, ensuring long-term lawn health without the risk of toxicity. Quick-release fertilizers, on the other hand, act immediately when watered, providing fast results and a higher concentration of nutrients.

It’s generally recommended to opt for controlled-release fertilizer for overall lawn health. However, quick-release fertilizer can be a suitable choice if you need quick results or have specific nutrient demands.

Nutrient Content in Liquid and Granular Fertilizers

Both liquid and granular fertilizers contain the three essential macronutrients: nitrogen, phosphorus, and potassium. These nutrients are crucial for grass growth and development. The ratio of these nutrients, often referred to as N-P-K, is typically displayed on fertilizer labels. For example, a 24-25-4 ratio means the fertilizer contains 24% nitrogen, 25% phosphorus, and 4% potassium.

Both types of fertilizers provide the same nutrients to your grass, and most fertilizers are safe for all grass types.

Pros and Cons: Liquid vs. Granular Fertilizer

Liquid and granular fertilizers each have their own advantages and disadvantages.

Liquid Fertilizer Pros:

  • Nutrients are immediately available to the grass after application.
  • Provides an even distribution of nutrients due to identical ratios in every drop.
  • Easy application process, often using a spray bottle attached to a garden hose.
  • Can be mixed with herbicides or pesticides for a comprehensive treatment.
  • Shows faster results due to increased mobility in the soil.
  • Ideal as a starter fertilizer for new lawns or for reviving dying lawns.

Liquid Fertilizer Cons:

  • Can stimulate rapid shoot growth and hinder root development if overused.
  • Requires more frequent re-applications compared to slow-release granular fertilizer.
  • Generally more expensive, especially for large lawns requiring multiple applications.
  • Shorter shelf life compared to granular fertilizer.

Granular Fertilizer Pros:

  • Ideal for long-term grass health.
  • Requires fewer applications compared to quick-release liquid fertilizer.
  • Longer shelf life and often more cost-effective, especially when bought in bulk.
  • Can be applied regardless of the time of day or year.

Granular Fertilizer Cons:

  • Requires a spreader for application, which can be more time-consuming.
  • Not suitable for lawns requiring immediate nutrient boosts.
  • Requires sufficient watering for nutrients to reach grassroots.
  • Some granules may contain dust or broken particles, leading to uneven distribution.

How to Apply Liquid Fertilizer

Applying liquid fertilizer is less physically intensive compared to granular fertilizer. Most liquid fertilizers can be applied by attaching a spray bottle to a garden hose.

Here’s how to apply liquid fertilizer:

  1. Choose a clear, sunny day with no wind to avoid wasting the fertilizer or causing burn spots.
  2. Apply the fertilizer at the end of the day when the temperature has cooled.
  3. Spray an even application across the lawn, making sure not to apply too much in one area.
  4. Walk backward as you fertilize to avoid stepping on the freshly treated grass.

How to Apply Granular Fertilizer

There are three tools you can use to spread granular fertilizer: a rotary spreader, a drop spreader, or a hand-held spreader. The choice of tool depends on the size of your lawn.

Here’s how to apply granular fertilizer:

  1. Calibrate your spreader according to the instructions on the fertilizer bag.
  2. Pour the granules into the hopper, being cautious not to spill any on the grass.
  3. Walk around the perimeter of your lawn, spreading the granules evenly.
  4. Once you’ve covered the perimeter, move in straight lines to cover the middle section, overlapping slightly to avoid missing any spots.

Factors to Consider When Choosing a Fertilizer

When selecting a fertilizer, consider the following factors:

  1. Your lawn’s health: If you have a healthy lawn, slow-release granular fertilizer is a great choice. Quick-release fertilizer may be more suitable for struggling grass or when establishing a new lawn.
  2. Application convenience: Liquid fertilizer is easier to apply, especially when using a spray bottle attached to a garden hose.
  3. Application frequency: Granular fertilizer requires fewer applications than liquid fertilizer.
  4. Budget: Granular fertilizer is typically more cost-effective, particularly when purchased in bulk.

FAQs on Liquid vs. Granular Fertilizer

Q: What other uses does liquid fertilizer have?
A: Liquid fertilizer can be used to feed seedlings, potted plants, container gardens, or as a pick-me-up for plants that need a nutrient boost.

Q: What other uses does granular fertilizer have?
A: Granular fertilizer can promote healthy outdoor garden beds by applying it before planting seeds or seedlings. It can also be used in planting holes before transplantation.

Q: Can liquid and granular fertilizers be used simultaneously?
A: Yes, you can use both types of fertilizers together. For example, you can apply a controlled-release granular fertilizer to jumpstart new grass growth and then spray liquid fertilizer every few weeks for continuous nutrition.
