It thrives in full sun to partial shade and can be grown in USDA hardiness zones 5 to 9. The plant can be propagated through seeds, cuttings or division.
Watering Needs
Once established, Eriogonum vimineum Dougl. ex Benth. var. californicum Gandog. is drought-tolerant and requires infrequent watering. Water the plant deeply and thoroughly, allowing the soil to dry out between watering sessions. Overwatering may lead to root rot and other fungal diseases.
Fertilization
Eriogonum vimineum Dougl. ex Benth. var. californicum Gandog. does not require regular fertilization. However, you can apply a slow-release fertilizer in the spring to provide the plant with nutrients. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Avoid over-fertilizing, as it can lead to excessive foliage growth at the expense of flower production.
Pruning
Eriogonum vimineum Dougl. ex Benth. var. californicum Gandog. does not require frequent pruning, but you can remove dead or damaged stems anytime during the growing season. After flowering, you can cut the plant back to promote bushier growth. Avoid pruning the plant in late summer or fall, as it may interfere with the next year's growth and flower production.
Propagation of Eriogonum vimineum Dougl. ex Benth. var. californicum Gandog.
Eriogonum vimineum Dougl. ex Benth. var. californicum Gandog. can be propagated through seeds and cuttings. The propagation method that works best may depend on the specific climate and environment it will be grown in.
Propagation by Seeds
Seeds can be collected from the plant when they are ripe and dry. They can then be sown directly in the ground or started indoors and transplanted later. The seeds should be planted at a depth of about 1/4 inch and spaced about 6 inches apart. The soil should be kept moist but not waterlogged.
Propagation by Cuttings
Eriogonum vimineum Dougl. ex Benth. var. californicum Gandog. can also be propagated by cuttings. In early spring, take cuttings about 4 to 6 inches in length from the parent plant. Remove the leaves from the bottom half of the cutting and dip it in rooting hormone. Plant the cutting in sandy soil and keep it moist. After a few weeks, the cutting will develop roots and can be transplanted to its final location.
