Soil Requirements
The hairy goldenrod plant thrives in well-drained soils that are rich in organic matter. It prefers soils that are slightly acidic with a pH between 5.5-6.5. The plant can also tolerate soils that are slightly alkaline but may not grow as vigorously. Soil moisture is also a crucial factor in the growth of the hairy goldenrod plant. The soil must remain consistently moist, especially during the plant's flowering period.
In conclusion, the hairy goldenrod plant has specific growth requirements that should be taken into consideration. The plant requires full sun exposure, cooler temperatures, and well-drained soils with consistent moisture. By providing these optimal growth conditions, the hairy goldenrod can grow into a beautiful and thriving perennial herb.
Cultivation methods
Solidago hispida Muhl. ex Willd. is a hardy plant that grows best in well-drained soils with a neutral pH. It thrives in full sun but can tolerate partial shade. The plant is propagated by seed or division of the rhizome. Seeds can be sown directly into the soil in the fall or spring, and rhizome division is best done in early spring.
Watering needs
The plant requires regular watering during the growing season, especially during hot and dry weather. It is important to avoid over-watering, which can lead to root rot. One inch of water per week is sufficient for the plant to thrive.
Fertilization
It is advisable to fertilize the plant once a year in early spring using a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Over-fertilization can cause excessive growth and lead to weaker stems.
Pruning
The plant does not require regular pruning but can benefit from occasional trimming to control its shape and prevent the plant from spreading too much. Cut back the stems in late autumn after the flowering season. It is recommended to wear gloves when pruning as the plant can cause skin irritation.

- Replant the divided sections immediately in well-draining soil.
Cuttings
Cuttings are a quick and easy way to propagate Solidago hispida. You can take cuttings during spring or early summer when the plant is actively growing. Follow these steps:
- Cut a 3-4 inch stem from the parent plant.
- Remove the leaves from the lower end of the stem leaving only the top 2-3 leaves.
- Dip the cut end into rooting hormone.
- Plant the stem in a pot filled with a moist, well-draining potting mix.
- Keep the soil moist and place the pot in a bright location.
- After the cutting has rooted and begun to grow, transplant it to the garden.
By following these propagation methods, you can easily increase the number of Solidago hispida plants in your garden or share them with other gardening enthusiasts.
