Are you excited for spring? March is the perfect time to step outside, feel the fresh air, and start planting for a beautiful garden. As the cold winter fades away, the soil slowly begins to warm up.
This makes it an ideal time to plant hardy perennials that can survive changing weather and bloom year after year. The best part? These plants need very little care once they are established. If you want a low-maintenance garden that looks dreamy from early spring to late summer, this guide is for you.
March planting gives roots enough time to grow strong before summer heat arrives. Even if there is a surprise late frost, many of these perennials can handle it easily. Let’s look at the best options you can plant now for a colorful, stress-free garden.
Why Plant Hardy Perennials in March?
Strong Root Growth Before Summer
When you plant in March, the soil is cool but not frozen. This allows roots to grow deeply before hot weather begins. Strong roots mean healthier plants.
Less Watering Needed
Hardy perennials are naturally tough. Once settled, they need less water and care compared to seasonal flowers.
Blooms Every Year
Unlike annual plants that last only one season, perennial flowers come back every year. You plant them once and enjoy them for many years.
Smart Watering Tips for Early Spring
While March is great for planting, you should water wisely.
- In cool weather, plants do not dry out quickly.
- Too much water can cause plant diseases.
- On sunny days, especially if using a cold frame, plants can heat up fast and dry out.
The key is balance. Check the soil before watering. If it feels damp, wait.
