Cosmic Stone and Garden Supply has been your local stop for the highest quality gardening and landscaping supplies since 2007.  We specialize in offering a variety of all-natural, Maine based products as well as the expertise to help with your landscape project.  We offer several mulch products, a variety of stone sold individually or by the pallet, as well as compost, loam, and other aggregates.


Whenever possible, we use Maine products.  Our entire yard is chemical and dye free.  We have a variety of Mulch, Compost, Loam, and Stone Products for you to choose from.  Our prices are reasonable as is our delivery.  Our delivery fee is one price for up to 10 yards of mulch or 6 yards of stone/loam/compost.  Our goal is to get your products to you in a few days.  Call us and we can help you with any questions you may have.


We also offer stone birdbaths, granite tables, and granite planters, all in different sizes.  They are found throughout the yard for when you are looking for a unique yard piece or perhaps the perfect gift.  Our selection is always changing as we make all of these products in Topsham.  Don't see exactly what you want, let us know.


Our yard is constantly refreshed to provide you with what you need, when you need it.  We use the same suppliers for our products all season long so the mulch you buy in May will match what you need to spruce things up in August.


We hope to open in late April and begin deliveries as soon as the heavy loads road postings come down in early May.Maine mulch.  Maine garden.  Maine compost.  Maine loam.  Maine stone.  Brunswick Mulch.  Topsham Mulch.  Freeport Mulch.  Bowdoin Mulch, Harpswell Mulch, Bath Mulch, Bowdoinham Mulch, Phippsburg Mulch, Brunswick Compost.  Topsham Compost.  Freeport Compost.  Bowdoin Compost, Harpswell Compost, Bath Compost, Yarmouth Mulch, Yarmouth Compost, Maine stone, Topsham Stone, Brunswick Stone, Harpswell Stone, Bowdoin Stone, Arrowsic Stone, Bowdoinham Stone, Midcoast Stone, Midcoast Mulch, Midcoast Compost,  Bowdoinham Compost, Phippsburg Compost, MOFGA, MOFGA Compost, Mulch Delivery.
