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.

Amazing daily devotional.
Format: Hardcover
The very best morning devotional book I have ever purchased. I have given several copies to friends and ordered the large print edition for myself as began on January 1. I read it complete in 2025 and started again this year.

Insightful and encouraging as well as biblical
I've been a Christian for over 40 years. This is hands down the best of ocean life ever read. I've read os won't chambers and Charles spurgeon. And they're great. But what I got from this devotional was a perspective that I had never seen before it challenged my thinking on Grace and Grace living. If anyone is struggling with performance anxiety or general OCD. Focusing on the grace of God can be a great help. Every devotion highlights our need and God's wonderful perfume provision of grace. I can't recommend this devotional enough. In fact it's one of my number one gifts for the people at church.

Worth every penny!!
Color: Black
This kitchen sink caddy was exactly what I wanted. It's well made and small enough to fit on my new sink. It holds soap, dish rag or small sponge, drain stopper, and my two scrub brushes. Looks good, too
