All About Dasylirion Wheeleri
Desert spoon, common sotol or the sotol plant are all common plant names for Dasylirion wheeleri. This long-lived native of the Chiahuahuan Desert of northern Mexico has been naturalized as far north as southern Arizona, western Texas, and New Mexico. This evergreen succulent shows off its large rosette of serrated blue to grayish-green leaves radiating out in a circular axis from the tall stem. The leaf ends tend to become frizzy. Along with serrated leaf margins the plant has an overall hazy texture.
Dasylirion wheeleri is one of the species in this genus. It’s native to the arid lands of northern Mexico and the southwestern United States. It’s a slow to moderate growing perennial shrub with a single trunk that has no branches. Its upright sword-shaped leaves look stunning. Due to the inward curvature at the leaf bases, one of its common names is desert spoon.
The leaf blades are grayish-green in color. They are long, slender and have toothed margins. The stout short trunk that develops on mature plants grows from 9 to 15 feet tall. They are harvested for multiple reasons in the wilds among Arizona flora, Mexican forbs, and Texan prairies and deserts. Because of over harvesting, they’re now salvage restricted. Some plants live for up to 100 years.
Once the plant is mature, it blooms in early summer with a pole-like stalk of tiny flowers. Flowering occurs only every few years on flower spikes of clustered tiny blooms that grow in late spring to summer. The color of the flower indicates the gender of the plant. Male flowers are creamy yellow hues while female flowers are purple-pink.
These striking features have helped the plant win the Royal Horticultural Society Award of Garden Merit. As the name suggests this plant is used to make an alcoholic beverage called sotol, which has a long history of consumption among the people of Mexico who first cultivated the root of the plant for the beverage 300 years ago.
Dasylirion Wheeleri Care
Common sotol or spoon is a slow-growing, durable, carefree and drought-tolerant plant native to arid lands. Here are some specific care requirements for this perennial succulent xeriscape plant.
Light & Temperature
These plants are sun-loving and native to hot climates. Therefore, it’s best to grow the common sotol shrub in full sun. They can tolerate partial sun as well. The plant is hardy in USDA Zones 8-11. They prefer higher temperatures but will show some heat stress above 100°F. The plants cannot stand very long periods of frost.
They should be grown in areas where the temperature doesn’t go below 0°F in winters. Consistent exposure to these temperatures can kill a plant. Since it’s difficult to grow indoors, you may want to drape a frost blanket of some kind over the plant if sub freezing temperatures persist.
Water & Humidity
This plant is drought-tolerant and prefers dry conditions so it has little watering needs. Give it 1 inch of water per week upon establishment. You may have to water regularly but during extended drought in hot summers. After establishment, don’t apply extra water. Avoid watering the crown as that may result in root rot. During winters you can reduce the frequency of watering even further. Most of the time natural precipitation is enough for this plant.
Common sotol likes porous soils such as garden loam soil, sandy soil, and clay soil. These plants require higher concentrations of sand that provide fast drainage. The preferable pH range for the soil is between 5.5 and 6.7. A soil test can tell you if you’re in that range.
Spoon Flower Fertilizer
You don’t really need to fertilize the plant. However, light spring fertilization with a balanced formula will ensure good growth. Young common sotol plants benefit from a high phosphorus fertilizer applied sparingly in the first year of growth. This helps them establish their roots in the soil.
Common Sotol Propagation
You can propagate the plant by seeds or by cuttings. However, growing it from seeds is quite a time-consuming process as germination and establishment are slow. Instead, take a cutting from a parent plant with sterilized shears. Choose a plant that’s at least a few feet tall and a few years old. Set the cutting in a dry place out of direct sunlight to allow a callous to form over the cut.
Then plant it in a small pot in the same soil used to grow the parent plant, and lightly water. Keep the container in a bright, dry area. Within 2 to 4 weeks you’ll have baby sotol plant.
Pruning Dasylirion Wheeleri
Being a slow grower, the plant does not require pruning as such. You can remove dried spent flowers as needed. Prune out dried, yellow or senescent lower leaves any time of the year. Try not to prune otherwise, as this can damage your plant. Always wear gloves when you remove dead leaves to protect your hands from serrations on the fresh green leaves.
There are no serious growing problems with Dasylirion wheeleri. You just have to make sure that the soil in which they’re growing drains well. Chronically wet soil can lead to root rot.
Serious growing problems don’t occur, unless you’ve planted your common sotol in the wrong conditions. Ensure it has well-draining soil, full sun, and not too much water, and you’re set. Significant imbalances in any of these basic conditions can create optimal environments for root rot.
There are no known issues of pests with this plant.
The plant does not suffer from any particular disease. High humidity or overly wet soil can lead to fungal infections of root rot in some cases. There is no treatment for root rot once it sets in, and damaged plants will need to be disposed of. Avoid planting in that spot for at least a couple of seasons, and solarize the soil to kill of remaining fungi.
