Buying Guide: How to choose lawn fertilizers

Using lawn fertilizers is an outstanding lawn care manner. It makes grass color better. Besides grass needs to be recovered from stress, like winter or dry month. If you are using lawn fertilizer, weeds will stay away from your grass and diseases too.

How to choose lawn fertilizers?

There are few important points to think about when choosing lawn fertilizers.

Lawn fertilizer consists of Nitrogen (N), phosphorus (P), and potassium (K). These three nutrients your garden needs the most. But remember, don’t overdose. Too much nitrogen can cause extreme growth, leading to massive problems.

If you take a look on the fertilizer bag, you will see three numbers. These are percents if nitrogen, phosphorus, and potassium. The first number is for nitrogen, second for phosphorus and third for potassium.

10-10-10 mixture is a good basic mix for spring.

Example – take a look at this lawn fertilizer – . You will see numbers on the package – 10,0 and 6. It means – 10% of full weight is nitrogen, 0% phosphorus, and 6% potassium.

Important! – Check what kind of nitrogen is used in the product. Nitrogen can consist of fast-release or controlled-release nitrogen. Check this table for advantages and disadvantages.

Nitrogen Type Advantages Disadvantages
Fast release:

ammonium nitrate;

ammonium sulfate

1. Quick greening
2. When soils are cold it’s providing nitrogen
3. Inexpensive
1. Can cause fast growth
2. Can burn your grass
3. Losses through soil or air.
Controlled release:
(slow-release)sulfur-coated reactivated sewage sludge
1. The grass is growing more solid and sprucely.

2. Can’t burn grass

3. Don’t loss through soil or air.

1. Is working bad at cold soil

2. Expensive

3. Slow color change.

There are many types of lawn fertilizers. There is a particular lawn fertilizer for winter or fall. They are made for winter of/and falls because of high potassium structure. I don’t think that there is any obstacle not to use it in the spring too.

Potassium helps for heat and cold tolerance, resistance to diseases and of course – stress release. If you have new or freshly laid sod, I suggest starter products. They will help the grass to grow and will kill all harmful weeds.

Nitrogen helps plants to survive the winter and the heat. Also contributes to survive if the soil is too wet. Also makes grass greener.

Lawn fertilizer tips

  • Choose slow-release fertilizer. You can wait longer between applications – every six to eight weeks.
  • Don’t go over 25-0-6 percents.
  • Go with granules
  • Make first fertilize when the soil temperature is ~ 55 degrees (Fahrenheit).
  • You will know when the temperature reaches 55 degrees because lilacs begin to blossom and the grass starts growing.
  • Mid-April is the best month to fertilize
  • Second feeding should be placed after 4 weeks.
  • After the second week, fertilize every six to eight weeks.
  • Grass at the fall needs to be fed extra carefully, grass will need it more than in other seasons.
  • On all packages there is an application rate – don’t follow it. Start out only with a half of it.

When you are ready to fill the spreader – don’t do it on the grass. Or if you are doing it – put a tarp under it. This will prevent fallen fertilizer to burn the grass at that spot.

A broadcast spreader is a better choice than a drop spreader for homeowners. Broadcast spreaders are easier to use because they disperse the fertilizer wider. The best thing about broadcast spreader is that there’s less chance you’ll end up with strips in your lawn caused by not overlapping the rows correctly. Broadcast spreaders are much cheaper. They start at $32, while drop spreaders start at $84.

Clean stray granules, it’s good for nature.

  1. My wife and I are getting ready to start a garden, so thanks for the tips on choosing fertilizer. I like your point about applying fertilizer ever 6-8 weeks. I’ll have to make a schedule for fertilizing the lawn so I don’t use too much or too little during the spring.

  2. I had no idea that your plants need nitrogen, phosphorus, and potassium the most. My little brother is usually the one to garden, but I’ve been wanting to help him out. These tips will definitely help me get the best fertilizer. Thank you for sharing.
