When to Plant Perennial Flowers
Looking to build a garden that comes back year after year? Perennials are your go-to! These long-lasting beauties may die back in winter, but they come roaring back in springāstronger, fuller, and more vibrant.
Hereās what you need to know about when to plant perennial flowers:
Start Seeds in Spring
While some perennials are a little trickier to start from seed, many are totally doableāand budget-friendly!
Some take 3ā4 weeks just to germinate, so start early and follow those seed packet instructions closely.
Plant Mature Perennials in Fall
Buying from a nursery? The best time to plant mature perennials is in fallāat least 6 weeks before your first frost (October 20th in Central Ohio).
Why? Cooler temps + winter moisture = stronger root development.
