Frequently Asked Questions

What is the best source of nitrogen for lawns?

There are many different types of Nitrogen. The best source of nitrogen for your lawn is a blend of nitrogen sources. At lawnsynergy, we blend different sources of nitrogen into each bag so that your lawn is continuously fed. Cheap fertilizers only contain urea. Our fertilizers contain polymer-coated urea, ammoniacal, and bio-solids. By combining multiple nitrogen sources, you are sure to receive a lush lawn.

What is the best fertilizer for grass root growth?

15-20-12 Starter Lawn Fertilizer is the best fertilizer to use when trying to increase root development typically at seeding. Additional phosphorous enhances and encourages root development, and with our blended nitrogen sources, your grass seed will germinate and develop faster.

What is the best fertilizer for grass in summer?

It depends on your lawn type. Warm season lawns such as bermuda grass and zoysia grass greatly benefit from higher nitrogen fertilizer such as 20-0-10.
Cool season grasses benefit from lower nitrogen fertilizers during the summer months such as our 10-0-20.

How do I increase nitrogen in my lawn?

By simply applying lawnsynergy's 20-0-10 lawn fertilizer. 20-0-10 is a perfect blend of slow-release nitrogen for continuous feeding, and 10% potassium for strength and stress.

Apply fertilizer every 6-8 weeks for a nice dark green lawn.

Will too much nitrogen burn your grass?

Yes, it can. But a large amount of fertilizer must be applied for burn to occur. If you follow the label and apply the fertilizer at the correct time, and apply the correct amount, there is no reason to worry about burn.

Always water in your fertilizer application to begin activation.

Burn can occur if fertilizer is spilled in one area when applying. Be sure to begin pushing the spreader before opening the latch.
