Recommended Planting Times for Perennials
09/04/2014
From our experience and trials, we've learned the critical importance of knowing how to schedule your perennial crops. One planting time does not fit all when it comes to perennials, especially the broad selection offered by Walters Gardens. While some really need to be planted the year prior, others perform just as well when planted in spring for summer sales.
We've developed a chart that includes the recommended planting times for a number of key genera like Baptisia, Coreopsis, Echinacea, Helleborus, Hibiscus, and more.
