When to Plant Chives in Maine (2026 Guide)
Chives are a fantastic herb for local gardeners in Maine, known for their resilience and wonderful mild onion flavor. With a frost-free season of around 150 days in places like Portland, where the last spring frost is expected by May 8, chives are easy to grow and maintain. They start to pop up early in the spring and can be harvested until the October 5 first fall frost, making them a lovely addition to your garden.
These hardy perennials will thrive with minimal care, returning year after year with delicious green leaves and charming lavender flowers. Whether you are an experienced gardener in Augusta or a beginner in Bangor, growing chives is a rewarding activity that will enhance your culinary endeavors. Plus, their attractive blossoms can attract beneficial insects to your garden.
It's essential to understand the best times to start, transplant, and harvest your chives to ensure a successful crop. In Maine, you'll want to get your seeds started indoors by April 1, and transplant them outdoors around May 15. Keep in mind the chilly nights and occasional late frosts that can occur in early spring, especially in areas with microclimates.

Common Mistakes Growing Chives in Maine
- One common mistake is planting chives too early in Maine, especially in the northern areas, where late frosts can still occur. Always check frost dates to avoid losing your plants to unexpected cold snaps.
- New gardeners often forget to divide chive clumps every few years. This practice rejuvenates the plants and promotes healthy growth. Not dividing can lead to overcrowded conditions and reduced production over time.
- Ignoring local soil conditions is another pitfall many face in Maine. Maine's soil can be clay-heavy or alkaline, which might affect drainage and nutrient availability for growing chives. It's essential to amend the soil for optimal growth.
- Many gardeners in Maine underestimate the importance of harvesting flowers before they fully open. Harvesting too late can result in excessive self-seeding, leading to a crowded mess of chives in your garden beds.
- A frequent error is neglecting to water properly during unexpected dry spells. Maine's coastal and varying climate can cause fluctuations in moisture levels, so pay attention and water as needed to keep your chives robust.
