How To Grow Equisetum Hyemale

grow-equisetum-hyemale

Equisetum hyemale is commonly called scouring rush or rough horsetail. Equisetum is not a rush, fern, or reed. This horsetail is a non-flowering, rush-like, perennial, which is native to Europe, North America, and Asia, and is invasive in most places. It is very easy to grow Equisetum Hymale!

It is a single surviving genus that dates back 350 million years. Its name comes from the Latin word equus meaning “a horse” and seta meaning “a bristle.”

The stems

It occurs in wet woods, moist hillsides, and the edges of lakes, rivers, and ponds. This species has rigid, rough, hollow, jointed-and-segmented, bamboo-like, dark green stems that are about 1/2 inch in diameter at the base.

Photosynthesis happens in the stems of this plant. Fertile stems bear pine cone-like fruiting heads about 1-inch long, which contain a lot of spores.

If you live in an area that is frost-free, the evergreen stems are pretty in winter.

The stems are also high in silica and were used by early Americans for polishing pots and pans. (1)

The leaves

Tiny, scale-like leaves attached to the stem and fuse into an ash-gray sheath, which is a 1/4-inch long. The leaves end in a fringe of teeth marks at each stem node (joint). During the growing season, these teeth shed.

This ancient plant spreads by rhizomes (underground stem that acts like a root). It is commonly called horsetail or winter scouring rush, but there are several varieties. This particular species is one that has been used for centuries for tooth and gum care.

In your landscape

Horsetail reeds (Equisetum hyemale) is a great addition to the edges of backyard ponds and water features. The reeds thrive where soils are moist, but the plant remains above water. Depending on where you live, it can be invasive. This species of horsetail multiplies in a “thicket.”

The reeds may stay green where frost is not a concern. The reeds are typically grown only as a potted plant, because they spread quickly via underground rhizomes. It grows to a height of 2 feet to 4 feet.

Soil

Equisetum Hyemale tolerates a wide-range of moist soils It will even grow in up to 4 inches of standing water. A large colony of reeds forms in the wild. Equisetum Hyemale is a very aggressive plant, which needs to be restrained by a pot. Once established, it can be challenging to remove because the rhizomes spread wide and deep. Any small section of rhizome left behind will sprout a new plant. In water gardens, plant in pots, or it will choke out other plants.

This horsetail species likes a slightly acidic soil with a clay, loam, sand mix. It particularly likes wet sites. It is perfect for a bog garden, containers, or water gardens.

Light

Grow Equisetum Hyemale in full sun, partial sun, or partial shade depending on your particular climate.

Climate

This species of horsetail grows well in Zones 4 through 9.

Maintenance

Indoors or outside, be sure to cut off any rhizomes growing out of the pot. This will keep the horsetail from spreading into the pond or surrounding soil.

Place the pot so the rim is above the water surface, near the edge of a pond or water feature is perfect.

Prune the dead stems after they turn brown in winter. Provide some winter interest by leaving the stems in place until new stems emerge.

Watering

Water horsetail reeds twice-a-week or more, so the soil stays moist, almost wet. Pots sitting in water need less watering. Water pond plants only if the potting soil surface looks dry.

Pests

Equisetum Hyemale does not have any serious insect or disease problems. The only problem is its very aggressive and spreading nature.

Fertilizer

When the reed is actively growing in spring and summer or every two months, apply a fertilizer made for pond or bog plants. Follow the recommended applications on the fertilizer bag.

Grow Equisetum Hyemale Indoors

Although a bog plant, horsetail reeds are low-maintenance and do well in pots on your patio, too. Plant Equisetum Hyemale in a non-perforated, 1-gallon pot with drainage holes.

Lift the pot once-a-month to examine the drainage holes. Cut back any rhizomes that are trying to escape.

Indoors, grow Equisetum Hyemale in moist soil and with a lot of light. A sunny window is perfect.

Use a potting soil that works best for bog and water garden plants. Set the pot in water that is no more than 4-inches deep.

    First off, I want to say how much I love the garden summits, I have learned so much. Thank you for doing that. Second, I live in West Michigan and just discovered this spring that the weed I have been pulling in my front flower garden is horsetail. I’m near Lake Michigan and our soil is sandy and dry. However the horsetail grows very well here in dry sand. I am now harvesting it to make a High Calcium Tea from Rosemary Gladstar’s recipes. I dry in the dehydrator, cut, and store. I think it has a wonderful aroma once dried.

  • Tammy

    I would LOVE to grow this in my garden. I’ve had my share of dental problems and complications over the years and this would be so nice to have. Any ideas on where I can purchase a start of it? I checked with a few local nurseries here in the Dallas area and no one seems to have it.

    • Dawn

      I located a lot of horsetail growing at the river and brought home some root. Planted it in sand, watered it, and in two short weeks it was sending up large numbers of shoots. Have been drying the shoots, grinding them, and eating a heaping teaspoon each day for two weeks. Some of my cavities are looking better and some need much more time to respond. Thank you VERY much for this valuable information.

      Hi Tammy,

      I live in Dallas as well and have been looking for this species of horsetail. Even online and in stores, no one is selling the Hymale species. Let me know if you have any luck!

  • Lora Stone

    How does Equisetum Hyemale compare to Equisetum Arvense? Do they both work as well as the other?

    • Priti

      I watched Doug Simon’s DVD called “Alternatives to Dentists” and he says that you need the hymale species. Avernase is available in abundance, so I contacted the grow network to ask, but no response. If you find something out, let me know!

  • Debbie

    Wild horsetail grows like a weed along the sides of my driveway, which runs through a wet area. It is not as large as the plant described in the article, maybe growing 6-9″ tall, but I am wondering if it can be used for the same purposes. I am slowly trying to identify and find uses for the many varieties of native plants that grow around here. It is much easier and better than destroying them as weeds and replacing them with cultivated ones.

  • Bonnie

    Echoing the posts above, Tammy, and Lora, where might we purchase starts? and how does hyemale compare to arvense? Thanks for the great post.

  • Yes! I have been searching for Equisetum Hyemale TO GROW for months now and can not find a source of it in Canada (B.C.).
    Can anyone help me here?
    Thanks!

  • Sonya

    I really enjoyed this article thank you! I’m trying to reverse periodontal disease organically. Please explain how to use this plant, eg tea, chew n spit, swallow etc. Also what part of plant to use and how/when to harvest it. Any tips on getting rid of gum disease would be appreciated as well. My dentist suggested I rinse my mouth with diluted chlorine and told me that once you have it there is no cure. I’m sure there’s another way.

    • Darla

      Marjory has been recommending a book by Doug Simons called Alternatives to Dentists. I am sure it will have some good information on reversing gum disease. My husband had gum disease and he started using a toothpaste called thieves aromabright toothpaste marketed by young living essential oils. Over a years time it has totally reversed his. I’m sure a lot would have to do with the severity of the disease as to how long it would take, but I would check out those two things.

  • Joy

    I’m not sure why anyone with livestock would want it around, as it can be poisonous in large enough doses. While adults won’t eat it, young animals may.

  • I just bought some on EBay to plant. It arrived quickly and in great shape. I will be planting it tomorrow. Thank you for the timely article!!

    • Judith

      Great info, thanks so much.
      I was not sure how to grow it indoors.
      Does anyone know a good source to buy it from, that will ship here to Minnesota? I was going to order it from Amazon, but I am not sure which seller to use.

  • This is the variety I am familiar with around western Washington. https://www.pugetsound.edu/academics/academic-resources/slater-museum/exhibits/terrestrial-panel/common-horsetail/ (Equisetum arvense)
    It resembles a bottle brush. The article by a local collage describes the native uses. I have only used it for scouring after cooking on a wood fire. It would be interesting to try drying it and maby use the powder as an abrasive additive to my baking soda/coconut oil dentifrice.

  • Victoria

    How is horsetail used to care for the teeth?

  • Tirzah

    How do you have drainage holes in a non perforated pot? (Sincere question, not trying to be a smart alec.)

    • Betsy

      Hi Tyra’s, I think what they meant is you plant in the pot with drainage holes and place that pot into another that is not perforated. So it will hold water and you can lift out the plants and trim the little roots that are trying to escape.

  • Mary McLaughlin

    How do you use the horse tail plant for dental care? The article said all about growing it but not what to do with it for your teeth.

  • Veronica Scott

    Thank you for the information on how to grow Equisetum Hyemale.

    I’m very interested and wanted to try this herb.

    Please, direction on how to use it.

  • thar

    Highly invasive. No, I will not be growing this anywhere near my yard. However, I enjoy seeing it in our local parks.

  • I have heard that horsetail tea is good for urinal tract infections. Is this so?
