The soil should be well-drained, yet this species is adaptable to various soil types. When planting, ensure there is ample space for this plant to reach its mature height of 1.8 meters and spread its upright growth habit. Planting is best done outside of frost conditions, and regular watering is necessary to support its establishment, particularly during dry periods.

Pruning of Thalictrum flavum subsp. glaucum is generally minimal and straightforward.

To maintain the health and vigor of Thalictrum flavum subsp. glaucum, it is essential to meet its average water needs. Ensure that the soil remains consistently moist but well-drained, as overwatering can be just as detrimental as drought. During the growing season, particularly in the warmer months, monitor the soil moisture closely and water when the top layer begins to dry out. This species, while not drought-tolerant, is adept at utilizing the water provided efficiently. Watering should be reduced as the plant enters dormancy in the cooler months to match its decreased water requirement.
To ensure vigorous growth and optimal flowering, Thalictrum flavum subsp. glaucum requires proper nutrition through strategic fertilization. Commence feeding in early spring to coincide with the onset of new growth. A balanced, slow-release fertilizer is ideal, as it provides a steady supply of essential nutrients throughout the growing season. Apply the fertilizer according to the manufacturer's instructions, taking care to distribute it evenly around the base of the plant, but not against the stem to prevent any potential damage to the plant. A second application can be beneficial in midsummer to sustain the plant's needs during the peak of its flowering period. Regular fertilization not only enhances the ornamental qualities of the plant but also bolsters its overall health and vigor, allowing it to thrive in its setting.
