Light Conditions
Eriogonum desertorum typically grows in areas with full sun exposure. The plant requires at least six hours of direct sunlight every day to thrive. In areas with partial shade, the growth rate may be slower, and the plant may not reach full maturity.
Temperature Requirements
Eriogonum desertorum is native to the Mojave and Sonoran Deserts of North America, where temperatures can reach up to 120°F during the day and drop to around 50°F at night. The plant is able to tolerate a wide range of temperatures, but it prefers warm climates. The optimal temperature range for growth is between 70°F and 90°F. At temperatures below freezing, the plant will typically go into dormancy.
Soil Requirements
Eriogonum desertorum grows best in well-draining soil with low to moderate fertility. The plant is able to tolerate a wide range of soil types, including sandy and rocky soils. However, the soil must be well-draining to prevent waterlogging, which can be detrimental to the plant's growth. The ideal soil pH range for Eriogonum desertorum is between 6.0 and 8.5. The plant often grows in areas with low rainfall, so it has adapted to be drought-tolerant and can survive in soils with low moisture content.
Cultivation methods
Eriogonum desertorum, also known as Maguire's Buckwheat, is a drought-tolerant plant that grows well in dry and arid climates. It prefers well-drained soil and full sunlight and is hardy in USDA zones 5-9. If you plan to cultivate this plant, choose a well-drained location with plenty of sunlight and plant it during the spring or fall when temperatures are cooler.
Watering needs
Eriogonum desertorum is well adapted to arid environments and can withstand long periods of drought. However, it is essential to water the plant regularly during the first growing season to ensure that the roots establish well. After the first season, you can cut back watering to once or twice a month. The plant thrives in dry conditions, and overwatering can lead to root rot.
Fertilization
Eriogonum desertorum is a low-maintenance plant that does not require fertilization. However, if you notice yellowing leaves or stunted growth, you can apply a slow-release fertilizer during the growing season. Avoid applying too much fertilizer as it can lead to excessive growth, reducing the quality of flowers.
Pruning
Eriogonum desertorum requires minimal pruning to maintain its shape and promote healthy growth. Prune away any dead or wilted stems or flowers and trim back the plant to 6-8 inches from the ground during the winter season. This helps to rejuvenate the plant and promote new growth in the spring.
Propagation of Eriogonum desertorum
Eriogonum desertorum (Maguire) R.J. Davis, commonly known as desert wild buckwheat, is a drought-tolerant perennial plant species native to the western United States. This plant is a great addition to any xeriscape garden as it thrives in hot, dry conditions.
Propagation Methods
There are mainly two ways to propagate Eriogonum desertorum- through seed propagation and vegetative propagation.
Seed Propagation
Propagation through seeds is the most common and easiest method for propagating Eriogonum desertorum. The seeds of this plant can be collected from the matured seedheads.
The collected seeds should be stored in a cool and dry place until it is ready for sowing. The best time for sowing the seeds is in the fall when the temperature is cool. However, one can also sow them in early spring.
Before sowing, the seeds should be scarified with sandpaper or filed lightly to break the hard seed coat. Soaking the seeds in water for 24 hours helps in germination.
Sow the seeds just below the surface of the well-draining soil mix. Keep the soil moist but not waterlogged. The seeds should germinate in 14 to 21 days. Once the seedlings have grown big enough to handle, they can be transplanted into larger containers or directly into the garden.
Vegetative Propagation
Propagation through vegetative means is another method for propagating Eriogonum desertorum. This method is useful if one has a desirable plant, and the goal is to create more of it.
Vegetative propagation can be done in two ways - through root division and stem cuttings.
Root Division: In the early spring, when the plant is still dormant, carefully dig up the plant from the ground. Gently separate the clumps into smaller divisions. Make sure each section has roots and a few stems. Transplant each section immediately to its new location and keep it well-watered until established.
Stem Cuttings: In summer, select a healthy and disease-free stem from the plant. Cut a 6-inch length of the stem right below the leaf node. Remove all the leaves on the lower half of the cutting. Dip the cut end of the stem in rooting hormone and insert it well-draining soil mix. Keep the soil moist but not waterlogged and place it in a warm and sheltered location. The cuttings should start to root within six weeks.
Propagation of Eriogonum desertorum is not a difficult task, and anyone can do it with a little effort. With the right conditions, the plant will thrive and provide years of enjoyment.
