What Is Loam Soil?

Loam soil is a good mixture of Topsoil and Sand

If you are lucky enough to have good topsoil in your backyard, by all means, use your topsoil. All you will have to do is add fertilizer. If you are not so lucky--and your backyard is sand or heavy red or yellow clay, you can mix up a batch of loam soil.

 You can create your own loam soil by mixing these two ingredients together

• 2/3  Inorganic Topsoil (Little or no organic material added)
• 1/3  Pool Filter Sand

 Mix together thoroughly with a little water. Your soil should clump when squeezed. If your soil is mixed properly, it will not muddy your pond water.

You can purchase inexpensive bags of Topsoil at Lowes or Home-Depot. Don't buy brands like Scott's or Miracle-Gro, as they will contain too much organic matter that can foul your water. Buy an unbranded bag of topsoil instead.

You can purchase Pool Filter Sand at any store that sells pool supplies.

Marsh Marigolds prefer clay soil, make sure you add some clay to your loam soil mix for Marsh Marigolds!

Loam soil is well suited for all aquatic plants (except oxygenators). Oxygenators rarely need to be planted, just anchored in the substrate or in a container filled with sand or 1/8  inch pea gravel.

Sand holds little water but does allow for aeration and drainage.

 

Pondmegastore Tip In the south where there is extreme heat--Marsh Marigold will go dormant in summer but return the following spring.
