Heat Defense Granular 21-0-3 (12 lb)

Meet the granular built for hot, dry days

Exclusively available only in Sunday Lawn Plans

When temps rise and rain dips, this blend keeps your lawn on track. Premium ingredients support healthy growth and greener color, while the added surfactant helps water move into soil and reach roots more evenly, especially in arid regions. We also added leaf compost to support healthier soil. (Bet you didn’t know granular did that.)

One spread. One watering. Greener grass made simple. (We kept it humble. Your lawn won’t.)

How soon will I see results with Heat Defense Granular?

With good moisture, you should notice a greener, thicker lawn in about 1 to 2 weeks.

Is Heat Defense Granular safe for all grasses?

Sure is. While designed with the arid West in mind, this product can be used on any lawn or grass type.

When should I apply Heat Defense Granular?

Late spring is prime time, right before summer heat. You can also use it ahead of a forecasted dry spell.

Will Heat Defense Granular let me water less?

No. It improves water movement and soil moisture behavior but does not reduce irrigation needs. To reduce watering needs, add Sunday’s Drought Defense into your normal routine. You can use it alongside any Sunday lawn fertilizer, liquid or dry.
