Fertilizer: This plant does not require heavy fertilization. A balanced fertilizer may be applied once a year in spring to improve growth and flowering.
Water: Solidago graminifolia var. media prefers moderate moisture levels. It can tolerate drought conditions but will grow better with regular watering.
Propagation: This plant can be propagated by seed, division, or stem cuttings. Seeds can be planted in fall or early spring, while division and stem cuttings can be done in spring or early summer.
Cultivation Methods
Solidago graminifolia (L.) Salisb. var. media (Greene) S.K. Harris, commonly known as blue-stemmed goldenrod, is a perennial plant that is quite easy to cultivate. You can grow the plant from seeds, rhizomes, or cuttings. To grow from seeds, plant them in moist soil during the spring season. Sow the seeds lightly and ensure that there is not too much exposure to sunlight. The germination process usually takes around two weeks. Cuttings should be taken during late summer and planted in the same manner. On the other hand, rhizomes should be planted in the fall. Ensure that the soil conditions are excellent by mixing in compost or manure a few weeks before planting.
Watering Needs
Blue-stemmed goldenrod prefers moist but well-drained soils. For the plant to thrive, it needs to receive an adequate amount of water regularly. However, over-watering should be avoided as it can lead to root rot and other fungal diseases. The watering frequency will depend on the location and climate, but the thumb rule is to water when the soil feels dry to the touch. During particularly hot weather spells, the plant will require more frequent watering.
Fertilization
The blue-stemmed goldenrod will benefit from an annual application of fertilizer, particularly during the spring season when the plant is in its active growth phase. A balanced blend of nitrogen, phosphorous, and potassium is suitable for the plant. By using compost or manure, you can provide the plant with the necessary nutrients and trace minerals that will support its growth. It is recommended to refrain from over-fertilizing the plant, as that may lead to weak and spindly stems.
Pruning
Pruning the blue-stemmed goldenrod is generally unnecessary unless you want to improve the plant's overall appearance or manage its growth. If you want to manage the size of the plant, you can pinch back the stem tips after blooming. Pruning the plant's old flowers and foliage will encourage the production of new growth and extend the blooming season. Regular pruning will help the plant maintain its shape and appearance, and it also prevents pests and diseases from taking hold in overcrowded areas. However, care should be taken to avoid cutting into the woody stems as this may cause damage to the plant.
Propagation of Solidago graminifolia var. media
Solidago graminifolia var. media can be propagated through several methods:
Seed Propagation
Seeds of Solidago graminifolia var. media should be collected when they are ripe, which is usually in late summer to early fall. The seeds can be stored in a cool, dry place until ready to plant. To achieve optimal germination rates, the seeds require stratification, which means they need to be exposed to a cold, moist environment for a period of time. Sow the seeds in a potting mix, cover with a thin layer of soil, and water evenly. They require a mild temperature and moisture to germinate properly. Germination of seeds is typically successful within 2-3 weeks.
Division
Solidago graminifolia var. media can be propagated easily through division. Divide the clumps of plants in spring or fall when the plant is not in bloom. Use a sharp tool to separate the plant into smaller sections. Replant the divided segments, covering their roots with soil and watering immediately. Make sure to place the divided plants in an area with the same level of sun and soil moisture as their original location.
Cuttings
Cuttings can also be used as a propagation method. Choose healthy stems that are about 4-6 inches in length. Take these cuttings in late spring or early summer when the plant is actively growing. Dip the base of the cutting in rooting hormone and plant in a seedling tray containing a well-draining medium. Water consistently and avoid exposing the cuttings to direct sunlight. The plants should root within 2-3 weeks. Once the cuttings have established roots, they can be transplanted into individual containers and then re-potted into larger containers before transplantation to the garden.
