When new growth appears, fertilize. But some gardeners prefer to dig the corms in fall after the leaves have yellowed, allow them to dry, store at a cool temperature in a dry material through winter, then replant in spring. I have not grown this plant, but there are those who think this process leads to better blooms. The bottom leaves of my plants are turning yellow, and the green leaves are starting to curl. Primroses are grown outdoors in beds or containers during the cooler months.
Primroses prefer partial or bright shade.
Best results come with an organically enriched, moist but well-draining soil. I live in Galveston County on wooded property with gumbo soil. The area is in partial to heavy shade. I'm looking for shrubs and ground covers that will live in this situation. We want a natural and informal look, like azaleas and native plants, and have heard that hydrangeas might be good.
