Light Requirements
Galium angustifolium Nutt. ex Gray ssp. onycense (Dempster) Dempster & Stebbins is a shade-tolerant plant. It typically grows in partially shaded areas where it receives filtered sunlight or dappled shade throughout the day. It can also tolerate full shade, but it grows slower in these conditions.
Temperature Requirements
The Galium angustifolium Nutt. ex Gray ssp. onycense (Dempster) Dempster & Stebbins is native to mountainous regions of western North America, where it grows in cool and moist environments. It grows best in a temperature range of 50-70°F (10-21°C). In hot and dry conditions, the plant can wilt and even die.
Soil Requirements
The plant prefers well-draining soils that retain moisture but do not become waterlogged. It grows best in soils with neutral to slightly acidic pH, ranging from 5.5-7.0. The Galium angustifolium Nutt. ex Gray ssp. onycense (Dempster) Dempster & Stebbins grows in a wide range of soil textures, from sandy to clay loam, but it prefers soils with higher organic matter content. The plant also benefits from a layer of organic mulch around the base to retain moisture and suppress weeds.
Cultivation
Galium angustifolium Nutt. ex Gray ssp. onycense (Dempster) Dempster & Stebbins thrives in well-drained, sandy soil. It prefers full sun but can tolerate some shade. The plant is hardy in USDA zones 3 to 7. The best time to plant Galium angustifolium is in the fall or early spring. Use cuttings or seeds to propagate the plant.
Watering Needs
Galium angustifolium requires moderate watering. The plant is drought-tolerant but needs regular moisture during the growing season. Water the plant deeply and infrequently, avoiding watering the leaves. Overwatering can cause root rot.
Fertilization
Galium angustifolium does not require heavy feeding. A light application of a balanced fertilizer in the spring can help promote growth. Avoid fertilizing the plant in the fall or winter since this can promote new growth that can be damaged by frost.
Pruning
Pruning Galium angustifolium helps keep the plant healthy and promotes new growth. Prune after the plant has finished flowering in late summer. Cut back the stems to the base of the plant. This will encourage new, bushy growth and prevent the plant from becoming leggy.
Propagation of Galium angustifolium Nutt. ex Gray ssp. onycense (Dempster) Dempster & Stebbins
Galium angustifolium Nutt. ex Gray ssp. onycense (Dempster) Dempster & Stebbins, commonly known as slender bedstraw or northern bedstraw, is a beautiful and fast-growing plant. It is an ideal plant for propagation since it can be easily propagated by both seeds and cuttings.
Propagation by Seeds
The ideal time for sowing the seeds of Galium angustifolium Nutt. ex Gray ssp. onycense (Dempster) Dempster & Stebbins is in the early spring. The seeds can be sown directly in the garden bed, or they can be started indoors and transplanted later.
Before sowing the seeds, prepare the soil by loosening it to a depth of about 2-3 inches. Spread the seeds on the soil, and lightly cover them with a thin layer of soil. Water the soil gently to keep it moist, but not overly wet.
The seeds will germinate within 10-15 days, and the seedlings will be ready to transplant after about four weeks. Transplant the seedlings to their permanent locations, spacing them about 6-8 inches apart.
Propagation by Cuttings
Galium angustifolium Nutt. ex Gray ssp. onycense (Dempster) Dempster & Stebbins can also be propagated by stem cuttings. The best time to take cuttings is in the spring or early summer.
To take the cuttings, select healthy stems, and cut them to a length of about 4-5 inches. Remove the lower leaves, leaving only a few pairs of leaves at the top of the stem. Dip the cut end of the stem in a rooting hormone, and insert it into a pot filled with moist soilless potting mix.
Cover the pot with a plastic bag to create a humid environment, and place it in a bright location out of direct sunlight. Keep the soil moist, and within a few weeks, the cuttings will develop roots and new growth.
Once the roots have developed, transplant the cuttings into their permanent location, spacing them about 6-8 inches apart.
