LAWN PLAN EXCLUSIVE

Soil Helper pouch

When water won't soak in, nutrients can't either

If your lawn has compacted soil, water-resistant patches, or just doesn't respond well to fertilizer, the soil might be the problem. Soil Helper combines 22-0-3 fertilizer with surfactant technology. The surfactant helps water spread and penetrate instead of running off or pooling. Nitrogen feeds growth. Seaweed supports root strength. Potassium improves stress resilience.

The good stuff inside

  • Surfactant technology Helps water penetrate compacted soil
  • Nitrogen 22-0-3 NPK Growth and greening once water reaches roots
  • Seaweed extract Root strength and heat tolerance
  • Potassium Stress resilience and water management
  • Zero pesticide fertilizer—everything you need, nothing you don't
  • Universally loved by climates and grasses

How to use

Apply in late spring or early summer before drought conditions.

1. Apply early morning or evening to a well-hydrated lawn.

2. Connect sprayer to hose and pouch.

3. Spray evenly until pouch is empty (about 10-15 minutes).

4. Water thoroughly after application.

5. Reapply every 4-6 weeks during growing season.

I see Soil Helper on my plan. What is that?

Soil Helper is a 22-0-3 fertilizer with surfactant technology to improve water flow in tough soils. The surfactant helps water spread and penetrate instead of running off or pooling. It's assigned to plans in drought-prone regions or for lawns with compacted, water-resistant soil. Think of it as fertilizer plus soil conditioning.

How do I know if my soil needs Soil Helper?

Water puddles or runs off instead of soaking in. Grass stays dry even after irrigation. You see dry patches next to wet spots. Push a screwdriver into the soil—if it's hard to penetrate, you have compaction. Soil Helper addresses these water penetration problems while feeding your lawn.

Should I aerate before or after applying Soil Helper?

Either works. Aerating before lets the surfactant penetrate through the holes. Aerating after is fine too. If you're doing both in the same week, apply Soil Helper first, wait 2-3 days, then aerate. The surfactant will help water move through the new aeration channels.

Can I apply Soil Helper if rain is expected?

Light rain 24+ hours after application is fine. Heavy rain within a few hours can wash the surfactant away before it works. Check the forecast and aim for a dry, clear day for application when possible. The surfactant needs time to break down the soil's water resistance.

Not perfect but better than what I had

I was paying a lot of money for professional fertilization services that nearly killed my lawn. I’m trying to do it in my own and while it’s not the best on the block, it’s way better than it was.

So far so good

It's early in the process, but I do see that my lawn is much greener than the neighbors, and there are less weeds. The pet spot repair has been great!

Great service

I have struggled with growing a lush green lawn for ever. I started the tailor made program with Sunday and it’s been amazing. I was sitting out in front of my house yesterday and a man walking his dog said you have the best lawn in the neighborhood. Highly recommended product.
