One of the questions we get a lot is "What mix do I plant in my clay soils?" But, what is clay soil? Let's define it...

Clay soils are just soils that have a higher percentage of clay particles than silt or sand. Clay particles are smaller than silt and sand and tend to pack together which causes water to pool after rain events or from melted snow and runoff. Compaction from pedestrians or machines can exaggerate this packing of clay particles making the soil almost impenetrable to water. Clay soils can range from marginally clay dominant soils to almost all clay soils. OPN Seed's Clay Soil Mix is good for most areas where clay soils are found. The native species are adapted to grow in these soils and should do so.

Some things to remember:

Please keep in mind that this mix will take 2 to 3 growing seasons to fully establish and may display stunted growth as it works to establish. There are always exceptions and where this mix will grow is no different.

If the soil is very compacted, you may need to break it up before seeding. Contact us if you have questions about this.

If your soils are so clay based and compacted that they hold water like a swimming pool for weeks and months at a time and you can play a pickup basketball game on the other parts, you may need to amend the soils before planting.

Contacting your county Soil and Water Conservation District to get a soil test conducted may be a good idea in certain circumstances.

In most cases where these areas pool water for a few days and then it drains into the soil, this is your mix! Contact us if you have questions. We're here to help!

All of our native warm season grasses and seed mixes are sold PLS.

Broadcast Seeding is the process of sowing seed by hand. The seeds are sprinkled into the soil and can be lightly raked in to ensure germination.
