March marks the beginning of spring for many gardeners in Zone 3, a region characterized by cold winters and short growing seasons. Planting perennials during this time can set the foundation for a vibrant and lush garden throughout the year. Choosing the right perennials is crucial to ensure they establish well and thrive in the cooler climate.
Why Plant Perennials in March?
Planting perennials in March allows them to develop strong root systems before the heat of summer. Early planting helps perennials establish themselves, leading to better flowering and increased resilience against pests and diseases. Additionally, planting in early spring takes advantage of the natural moisture in the soil and longer daylight hours.
Top Perennials for Zone 3 Gardens in March
- Peonies (Paeonia) – Hardy and fragrant, peonies thrive with early planting and will reward you with stunning blooms in late spring to early summer.
- Hostas – Ideal for shaded areas, hostas are low-maintenance and provide lush foliage throughout the growing season.
- Daylilies (Hemerocallis) – These adaptable perennials are tolerant of various conditions and produce vibrant flowers from early summer onward.
- Black-eyed Susan (Rudbeckia) – Bright and cheerful, Rudbeckia can withstand cold soils and bloom profusely in summer.
- Lavender (Lavandula) – Though sensitive to harsh winters, hardy varieties can be planted early to establish roots for later flowering.
Preparation Tips for March Planting
Before planting, prepare your soil by removing weeds and adding compost to improve drainage and fertility. If the soil is still frozen or overly wet, wait a few weeks until conditions improve. Consider starting some perennials indoors or in cold frames to give them a head start if the weather remains harsh.
Additional Tips for Success
- Plant during a mild spell to avoid damage from late frosts.
- Water newly planted perennials thoroughly to settle the soil around roots.
- Apply mulch to retain moisture and protect roots from fluctuating temperatures.
- Monitor weather forecasts and be prepared to protect plants from unexpected frosts with covers or cloches.
With proper planning and care, planting perennials in March can lead to a beautiful and resilient garden that blossoms year after year. Embrace the early season and enjoy watching your garden grow!
