Eriogonum abertianum Torr. var. villosum Fosberg typically grows in full sun with little to no shade. It requires direct sunlight for proper growth and development. Lack of sufficient light can lead to stunted growth and spindly stems.
Temperature Requirements
The plant prefers warm to hot temperatures. It is adapted to the arid climate of its natural habitat and can tolerate high temperatures during the day and low temperatures at night. The ideal temperature range for Eriogonum abertianum Torr. var. villosum Fosberg is between 60 to 90 degrees Fahrenheit.
Soil Requirements
Eriogonum abertianum Torr. var. villosum Fosberg requires well-drained soil. It grows best in sandy or gravelly soils with low fertility, which are characteristic of its native habitats. The plant can tolerate alkaline soils with a pH range of 7.5 to 8.5. It is not suitable for clay soils or soils with poor drainage.
Cultivation Methods
Eriogonum abertianum Torr. var. villosum Fosberg is a low-growing shrub that can tolerate heat, drought, and certain soil types. It prefers sandy, well-drained soil and grows well in full sun. The plant is hardy in USDA zones 5-9 and can be propagated through seeds or cuttings.
Watering Needs
While Eriogonum abertianum Torr. var. villosum Fosberg is drought-tolerant, it still requires regular waterings during its establishment period. Water the plant deeply and then allow the soil to dry out slightly before watering again. Mature plants may not require as much watering, but it's important to keep an eye on soil moisture levels during hot, dry weather.
Fertilization
Eriogonum abertianum Torr. var. villosum Fosberg doesn't require much fertilization but can benefit from a slow-release, low-nitrogen fertilizer in the spring or early summer. Avoid fertilizing in the fall, as this can promote new growth that may not have time to harden off before winter.
Pruning
Pruning for shape and size can be done in the late fall or early spring. Remove any dead or damaged branches, and cut back any overgrown branches to maintain a more compact size. Avoid heavy pruning, as this can damage the plant and reduce flowering. It's best to prune no more than a third of the plant at any one time.
Propagation of Eriogonum abertianum Torr. var. villosum Fosberg
Eriogonum abertianum Torr. var. villosum Fosberg can be propagated through seeds, cuttings, and division.
Propagation by Seeds
Seeds of Eriogonum abertianum Torr. var. villosum Fosberg can be collected from the ripe seeds which can be obtained by collecting the brownish-black seeds. Before sowing, the seeds can be stratified for 30-60 days at a temperature of 40-50 °F.
Propagation by Cuttings
Eriogonum abertianum Torr. var. villosum Fosberg can also be propagated by cuttings. Semi-hardwood cuttings are taken during summer, treated with rooting hormones, and placed in a well-drained potting mix. The cuttings should be kept in a propagation unit with high humidity until they root.
Propagation by Division
Division is a rapid and straightforward method to propagate Eriogonum abertianum Torr. var. villosum Fosberg. It involves separating the existing clumps into several smaller ones, each with roots, and transplanting them into prepared soil. The division should take place in early spring, and the new plants should be planted at a depth of 0.5 inch below the soil surface.
