Don’t Just Plant Seed—Give It What It Needs to Grow

When you plant new grass, the biggest challenge isn’t just getting it to sprout—it’s getting it to establish strong roots.

Starter fertilizer is designed specifically for new seed or sod, with higher phosphorus to help roots develop quickly and absorb nutrients more efficiently. 

Without it, your lawn may come in thinner, slower, and less resilient.

Lawn Synergy 15-20-10 Starter Fertilizer is specifically formulated to support early root development, uniform establishment, and steady growth during the critical first weeks after seeding or sodding.


Not All Starter Fertilizers Are the Same

  • 15-20-10 Formula - High phosphorus for faster root development
  • Slow-Release Nitrogen - Feeds longer for continuous growth.  
  • Micronutrients - Darker green color with iron and needed nutrients.

This balanced nutrient profile supports young turf when root development matters most.

Why Starter Fertilizer Matters

Without Starter Fertilizer, New grass struggles to develop strong roots early on.

That can lead to:

  • Thin, patchy growth
  • Slower germination
  • Weak turf that doesn't fill in propertly

Starter fertilizer gives new grass exactly what it needs during the most important stage of growth.


When to Apply

Use at the Time of Seeding or Overseeding

  • New Lawn installations
  • Overseeding thin or patchy areas
  • Sod installation

Starter fertilizer is most effective when applied at the time of planting, helping seeds establish faster and stronger.

Lawn Synergy 15-20-10 provides the structured, professional nutrition your lawn needs during establishment — when root development determines long-term success.

Great on paper, but milky
Size: 4 Ounce (Pack of 1)
Based on my research I think it's one of the best physical sunscreens. Highest active ingredient percent and good price. It is quite white and harder to melt in and I still tan quite deeply.

Too thick and Difficult to Spread
Size: 4 Ounce (Pack of 1)
I’ve been using this sunscreen for several years. It was getting a good rating from Environmental Working Group in terms of being healthy for the skin. However, I finally gave up on it because it is so thick and difficult to spread. There are other healthy sunscreens that are not so thick and chalky.

Not oily.
Sprays evenly. Does not have that bug spray sent. Lasts a long time. You don't have to overspray to get good coverage. Works great for mosquitoes.
