How to keep Solidago Erecta.
Light
The showy goldenrod does best when it receives continuous exposure to direct sunlight. While it can tolerate spots where sunlight is partially obstructed, it grows most vigorously in bright, open sun. Greater light intensity can boost its development. However, too much sunlight or light that is insufficiently filtered can cause damage. Considering the environments it normally inhabits, this outcome is to be expected.
Temperature
Showy goldenrod is native to habitats with temperatures ranging from 32 to 90°F (0 to 32°C). It favors moderate temperatures, so adjustments should be made during extreme weather to ensure its optimal health and growth.
Fertilizer
The best time to fertilize a Showy goldenrod is in early spring, when it is coming out of dormancy and entering active growth. Fertilization supplies essential nutrients for healthy growth. Although Showy goldenrod has fairly low fertilizer requirements, applying fertilizer annually can improve its survival and promote better, longer-lasting flowers.
Pruning
Showy goldenrod is a herbaceous perennial known for its vibrant yellow flowers. To maintain its health and appearance, prune it in early spring by cutting the old stems down to the base. This encourages new growth and prevents the plant from becoming overly leggy. Additionally, remove any spent blooms to promote continuous flowering. Be careful not to cut any healthy green tissue to ensure the plant remains in optimal condition.
Pot & Repot
For healthy growth and to prevent root rot, showy goldenrod needs excellent drainage when planted in pots.
