Jonathan Green’s Mag-I-Cal Plus for Lawns in Alkaline & Hard Soil contains sulfur and calcium sulfate dihydrate which lowers soil pH, is important to cell development and is vital to many grass plant functions. Poor soil that is hard and compacted is often the problem when it comes to growing a great lawn. When soil is too alkaline and compacted, air, water and nutrients cannot get down to the roots and the grass will not grow properly. Lawns thrive in slightly acidic to neutral soil with pH levels between 6.2 and 7.0. In soils with pH readings of 7.0 to 9.5, weeds thrive and the grass becomes light green and spindly. Additionally, Mag-I-Cal Plus helps to break up clay and compacted soils. This improves root penetration and promotes growth by increasing biological activity and releasing nutrients trapped in the soil.

Finally, a great pillow!
Size: Standard (Mid Loft), Number of Items: 1
Finally! After so much wasted money on sooooo many pillows, I come across this beauty! This pillow is amazing! I got the medium one, and it’s so perfect. Soft, yet supportive. I’m still surprised at how much I love it!

LOVE IT !
Size: Queen (Mid Loft), Number of Items: 1
I love this pillow. It is just right, firm enough yet soft. My head sinks in and is very comfortable. When I lift my head, the pillow bounces right back into shape. If it lasts, I will buy my family each a pillow as it is wonderful. I woke up with zero neck pain as I typically did when using a standard foam pillow. There is a very light scent yet when I covered the pillow with a protector casing and then a cotton case, there was zero scent. I highly recommend. Especially when compared to the comfort of a very expensive latex pillow my husband uses.

Memory foam could never
Size: Queen (Mid Loft), Number of Items: 1
Wonderfully firm, yet responsive and lightweight. Like a marshmallow for your head and neck. I'm a side sleeper, but this could be great for anyone needing firm but still very soft and comfortable support. Memory foam has nothing on actual latex.

Great pillow! I have two latex pillows now and I don't think I'll ever go back to standard pillows.
