Elm-Leaved Goldenrod
Elm-Leaved Goldenrod (Solidago ulmifolia) is a popular choice for gardens both informal and formal since it thrives best in full sun and is relatively drought tolerant. This is an herbaceous perennial native to North America. It has a simple spreading habit, with wiry green stems and small yellow flowers in late summer. The leaves of this plant are dark green and serrated. The foliage turns yellow in the fall and dies back in the winter. This plant is very hardy and can withstand extreme weather conditions, making it an ideal choice for gardeners in areas with hot or cold climates. This plant also produces a large amount of nectar, making it quite attractive to butterflies.
Elm-Leaved Goldenrod should be watered regularly; however, it is a drought-tolerant plant and will survive on very little water. Water it thoroughly when you do water it, and avoid wetting the foliage. It prefers moist but not soggy soil.
Elm-Leaved Goldenrod prefers full sun or very bright light. It will tolerate partial shade, but may not flower as prolifically. It also prefers well-drained soil.
Elm-Leaved Goldenrod is a very hardy plant and can tolerate temperatures from 10 degrees Fahrenheit (-12 Celsius) to 97 degrees Fahrenheit (36 Celsius). However, it does best in temperatures between 50 (10 Celsius) and 68 degrees Fahrenheir (20 Celsius).
Elm-Leaved Goldenrod prefers low to moderate relative humidity. A humidity level between 40 and 60% is ideal.
Elm-Leaved Goldenrod prefers a well-drained potting mix that is slightly acidic. A mix that is equal parts peat moss, sand, and loam is ideal. It should also be amended with compost or aged manure for an added boost of nutrients.
Elm-Leaved Goldenrod does not need to be fertilized frequently, but an occasional application of a balanced fertilizer will help promote healthy growth and blooming. For best results, use a liquid fertilizer every two weeks during the growing season. Avoid over-fertilizing, as this can have a detrimental effect on the plant.
This particular houseplant is relatively resistant to pests, however like most plants, it can still be prone to aphids and mealybugs. To get rid of these pests, it’s best to spray a strong blast of water directly onto the affected area. If that doesn’t work, then a solution of water and mild soap can be sprayed onto the leaves. Be sure to rinse off the soap solution from the leaves and not let it dry on the leaves. For a more natural alternative, neem oil is a great way to get rid of aphids. Just mix a few drops with water and spray it directly onto the leaves.
Repotting should be done every 2-3 years in spring or early summer when the plant needs more room for its roots. It’s best to use a pot that is one size larger than the previous pot. If you choose to use the same size pot, just add some fresh potting soil.
Pruning is not necessary, however it is recommended if you want to control the size and shape of the plant. Pruning can be done in late winter or early spring before the new growth begins. Cut back the topmost stems to the desired size. If there is any dead foliage, it can be removed.
Mulching is not necessary, however it can help retain moisture and keep weeds away. A 2-inch layer of shredded bark or shredded leaves is a suitable mulch.
Elm-Leaved Goldenrod can be propagated by division or by seed. To propagate by division, simply carefully dig up the plant and separate the roots into smaller sections. Replant the divisions in the same area. To propagate by seed, simply sow the seeds in pots in late spring or early summer. Keep the pots in a sunny spot and keep the soil moist. Once the seedlings have established, they can be transplanted to their permanent locations.
Elm-Leaved Goldenrod rarely requires support. However, if the base of the plant is weak, it may need a plant stake or trellis to provide support.
This houseplant doesn’t typically require a rest period, however it may benefit from one in order to help it keep its healthy growth. It should be kept in a cool location and away from any direct sunlight during its rest period.
Elm-Leaved Goldenrod is not toxic to pets.
