When to Plant Peonies

Fall and spring are the best times to plant these technicolor flowers. Peonies aren’t not frost tender (meaning they aren’t damaged by winter frosts), so they can be planted in whatever season works best for you. Late September and October are the prime months to take action.

The Peonies We’re Planting Right Now

Peonies come in a variety of bold colors, including pink, red, orange, yellow and white. But there’s also a special kind of peony that changes color as it blooms, and it’s called the Command Performance peony. The petals starts out deep red, then transforms to dark orange, peach and cream. Talk about gorgeous! Command Performance also has huge, fragrant blooms, but that’s just icing on the cake.

When planting peonies, space them about 3-4 feet apart. They should be placed no deeper than 2 inches below soil level. Peonies do best in full sun (about six hours of sunlight) with spots of shade, but the more shade they collect, the less flowers there are likely to be. Keep that in mind when finding the perfect spot for your new flowers.

Peonies grow best in well-drained soil and need to be watered at least once a week, especially if there’s a dry spell. There should be enough water to saturate the top five inches of soil. Compost, bonemeal, manure and fertilizer with high amounts of potassium and phosphorus will help your flowers develop.
