Creating an organic swimming pool

By Margaret Shea, owner Dropseed Nursery

Two of my favorite things are floating in the water and growing native plants–so building an organic swimming pool has been on my wish list for years. We finally finished the project just in time for this year’s swimming season and it is a delight!

We found a pond design that was the perfect fit for both growing native wetland plants and cooling off in the water. This pond combines a deep swimming zone (ours is 8’ deep) with an adjacent shallow planting zone.

Since our soil does not hold water, we used a liner beneath the entire area. The swimming zone is enclosed by a wooden box (ours is 10’x20’) that separates it from the planting zone. Outside of this box is the planting zone–3’ of sand and gravel that slopes towards the swimming area. The wooden box holds the substrate back from the deep area.

Our planting area surrounds the entire pool and varies in depth from 0-1.5’. Ideally you want equal areas for the planting zone and the swimming zone.  A perforated pipe is beneath the sand and gravel, and a bubbler circulates water through the plant roots, into the pipe, and back to the pool. The plant roots work together with the substrate to keep the water clean and clear.

The pond is built above grade to prevent run-off from entering the pool (run-off carries nutrients from the soil into the pool and causes algae blooms). This means you have to wait for rainfall to fill the pond–luckily, we have a nearby spring we were able to use to fill the pond more quickly.

It is wonderful to finally have a wet area to plant species like soft rush, lizard’s tail, pickerelweed, rattlebox and blue flag Iris. Blue vervain, foxglove beardtongue, swamp hibiscus, fox sedge, blue lobelia and other species are thriving right at the edge of the pond where they are out of the standing water, but their roots are wet. The plants were put in the ground in May but are already doing their job to keep the water clear. (See the list of botanical names below.)

We are not the only ones enjoying the pool. Tadpoles immediately colonized the pool. It has been fun watching birds drinking from the shallow area and we have a red-eared slider who sometimes basks on a rock between swims.

You can learn more about the process of building one of these ponds on David Pagan Butler’s YouTube channel.

Kentucky Botanical Symposium 2021 Speakers and Facilitators :

Brittney Viers, QF/NRCS TN State Coordinator/Southeastern Grasslands Initiative Liaison will be discussing Remnant Grassland Restoration on Private Lands in Kentucky and Tennessee.

“I’m originally from Northeast TX, which historically was the Blackland Prairie region.  My parents and I moved to southern Indiana since my Mother is from there.  I spent the rest of my childhood growing up on a row crop and cattle farm, but realized that natural history and ecology was my passion.  While in college at Murray State University studying Wildlife Biology I started working for IN DNR Div. of Nature Preserves and fell in love with the glades and barrens of southcentral IN.  I stayed at MSU to acquire a masters degree in Botany.  Because of my native plant and natural communities knowledge, I became a quail biologist in KY and later in TN working with private landowners desiring to restore habitat and improve their quail and other upland wildlife populations.  In 2019, I got the chance to have a strictly grasslands and quail focused position through a specialized Farm Bill grant in both KY and TN.  I will always strive to merge private lands work with restoration practices in degraded remnant grasslands since they are in desperate need of our recognition, care, and attention”.

Presidents Message

As we send out our last newsletter of the year, I wanted to give thanks to all our membership for supporting Kentucky Native Plant Society over the years and to all of the new members who continue to give me hope for our growing organization. We have been able to accomplish a lot this year as an organization, from organizing several virtual meetings, hosting a few in person hikes as well as contributing to native plant documentation through our inaturalist projects and plant atlas and distribution efforts. Our grants program continues to fund important native plant research conducted by students at universities and has expanded to include rare plant restoration efforts. The ladyslipper continues to be a monthly resource to find the latest native plant news and our website is continually improving as we provide compile native plant resources such as native plant sales, nurseries, herbariums and general native plant information . Our last organized event of the year, the annual Kentucky Botanical Symposium, is next Wednesday, December 8th, 9am-11:30am EST, and I encourage everyone to join in and learn about some current native plant projects programs occurring across our state and also learn from nearby state partners on existing programs that we could network or model here in Kentucky. I hope that everyone has had time to see the beautiful fall colors and the first glimpse of the frost flowers here in Kentucky, I know my family has enjoyed the first frost flower finds! Please check our website for any updates, upcoming planned events, visit our gear shop for gifts for friends and family, and visit a nearby natural area to view all of our wonderful native plants as they transition into winter. One of my favorite winter native plant activities is moss and lichen hunting, native plant wreath making, and reviewing the bud and bark characters of our many native trees.

Have a great December and upcoming Holiday fellow native plant enthusiasts!

For the love of Kentucky Plants,

Tara Rose Littlefield
