Soil   For terrestrial or bog gardens, Louisiana Iris grows well in almost any soil, but does best in sand/loam mix with additional rich organic compost added to the soil. Place the rhizome with 1/2 the rhizome in the soil, roots down, pointed side up.

In the Pond Use heavy loam soil in at least a 10 inch container, or larger, with two or three inches of water above the soil. Fertilize using Waterlily World Fertilizer Tabs throughout the growing/blooming season. (Fabric planters work well with all Louisiana Iris when planted in the pond, as Fabric Planters allow oxygen at the roots).

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 inexpensive / poor Topsoil at Lowes or Home-Depot. Good soil clumps together as a ball in your hand with only a little moisture. 

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.

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.

Some DO's and DON'TS regarding Aquatic Planting Soil  

DO NOT use potting soils ( as they are too light and will float right out of the pot). Potting Soil has organic material that will rot and foul your water!

DO NOT add too much composted material (as it is too rich in organic matter and it will ferment underwater and destroy the ecology of your pond).

DO NOT use 100% calcined clay as there is no nutritional value in calcined clay.

DO NOT add rocks, stones or pebbles to the top of your planting container as this will inhibit the growth of your plants. Plants do not grow in rocks and stones in nature!

DO NOT purchase API Aquatic Planting Media or Microbe-lift Aquatic Planting Media as these products are NOT suitable for waterlilies, lotus or most other pond plants. They are suitable for submerged grasses ONLY!

Planting Directions

For your terrestrial garden, plant your Louisiana Iris rhizomes in moist, rich, slightly acidic, loamy soil that is well drained, in full sun to part shade. Does well with up to an inch of water per week. Plant iris rhizome with tips up, leaving the top portion above the soil line and the bottom half of the bulb below the soil. Water after planting and when soil is dry and make sure plant has  5+ hours of sunlight. 

When placing your Louisiana Iris in the pond, use a container that is at least 10 inches wide. Use heavy loam soil and place the container in the pond with up to three inches of water above the top of the pot. Fertilize with Waterlily World Fertilizer Tabs from May until August.

Increase your blooms by adding aquatic plant tabs in the soil around your Louisiana iris throughout the growing season
