Ideally, the plant prefers temperatures between 60°F (15°C) and 80°F (27°C) during the day and cooler temperatures at night.
Soil Requirements
The ideal soil for mountain goldenrods is well-drained, moist, and nutrient-rich soil. The plant prefers soils with a pH range of 5.5 to 7.5. It can grow in different soil types, including sandy loam, clay, or loamy soils. Good drainage is crucial since the plant is susceptible to root rot if the soil becomes waterlogged. Supplemental watering may be necessary in dry weather conditions.
Cultivation Methods
The Solidago simplex Kunth ssp. randii (Porter) Ringius var. monticola (Porter) Ringius, commonly known as the Rocky Mountain goldenrod, grows best in full sun to partial shade, and can tolerate a variety of soil types. It can be propagated through division or seeds, and should be planted in the spring or fall.
Watering Needs
Rocky Mountain goldenrod requires regular watering during the first growing season to help establish a healthy root system. Once established, it is drought tolerant and only requires occasional watering during extended dry spells.
Fertilization
It is unnecessary to fertilize the Rocky Mountain goldenrod unless the soil quality is poor. If the soil is lacking in nutrients, add an all-purpose fertilizer in the spring when new growth appears.
Pruning
Pruning is not required for Rocky Mountain goldenrod unless you want to control its size or shape. To promote bushier growth, pinch back the tips of the stem in the spring when the plant is still young. Additionally, deadheading spent flowers will encourage new growth and prolong the blooming period.

Common Diseases
One of the most common diseases to affect Solidago simplex Kunth ssp. randii (Porter) Ringius var. monticola (Porter) Ringius is powdery mildew, a fungal disease that causes a white or gray powdery coating on the leaves. To manage this disease, it is important to provide good air circulation by thinning out crowded plants, removing infected leaves, and ensuring plants do not become overcrowded. You could also use fungicides to protect the plant against this disease, but it should only be used as a last resort.
Common Pests
Aphids are small, soft-bodied insects that can cause damage to Solidago simplex Kunth ssp. randii (Porter) Ringius var. monticola (Porter) Ringius by sucking sap from the plant’s leaves, causing them to curl, wilt, or turn yellow. To manage aphids, you could introduce natural predators like ladybugs to prey on them or use insecticides to control their population. You could also remove them by hand by spraying them off with a strong stream of water.
Another common pest that may affect Solidago simplex Kunth ssp. randii (Porter) Ringius var. monticola (Porter) Ringius is spider mites, which are tiny pests that feed on the plant’s leaves and cause them to turn yellow and drop off. To manage spider mites, you could introduce predatory mites or lacewings to the area, using insecticidal soaps and oils, or by using a strong spray of water. It is also important to keep the plant well-watered because spider mites thrive in dry conditions.
By being proactive and regularly inspecting and caring for your Solidago simplex Kunth ssp. randii (Porter) Ringius var. monticola (Porter) Ringius, you can ensure a healthy and long-lasting plant that will bring beauty to your garden for years to come.
