Understanding Perennials


Perennials are plants that live for more than two years, and they’re a wonderful addition to your garden. They offer variety, color, and a sense of stability while requiring less maintenance than annuals. Once established, perennials can take care of themselves through multiple growing seasons, with minimal interference from you.

When you plant perennials in August, you’re giving them a head start on the next growing season. This way, their roots can become established before the winter months, ensuring a strong and healthy plant come spring.

Plus, planting perennials in August could give you the opportunity to enjoy some late-season blooms, extending the beauty of your garden even further.

It’s important to choose perennials that are well-suited for your climate and growing conditions. Factors to consider include sunlight, soil type, and moisture level.

Keep in mind that perennials may have specific watering, fertilizing, and pruning needs, so familiarize yourself with the requirements of each plant before adding them to your garden.

Some perennials are more low-maintenance, while others may require a bit more attention. When selecting the right perennials for your garden, consider the following attributes:

  • Drought-tolerance: Perennials that can handle dry conditions are perfect for areas where water conservation is a priority.
  • Deer-resistance: If you’re located in an area with deer populations, choose perennials that are less appealing to these animals.
  • Pollinator-friendly: Select perennials that attract pollinators like bees, butterflies, and hummingbirds to support your local ecosystem.

Get inspired and start planning your August perennial garden today. A mix of carefully chosen perennials can be a long-lasting, beautiful, and eco-friendly addition to your outdoor space.

Factors to Consider

When selecting perennial plants for your garden this August, there are a few factors to consider to ensure their success:

1. Hardiness Zones: Make sure to choose plants suitable for your region’s climate. Check the United States Department of Agriculture (USDA) Hardiness Zone Map to find your zone, and select plants accordingly.

2. Sun Exposure: Different plants require different levels of sunlight. Some thrive in full sun, while others prefer shade or partial shade. Observe your garden’s sun exposure and choose plants that will thrive in those specific conditions.

3. Soil Type: Soil types vary from sandy to clay, and different plants have different soil preferences. Determine your soil type, and choose plants that will grow well in it. If necessary, amend your soil to improve its structure and fertility.

4. Water Requirements: Pay attention to the water requirements of your chosen plants. If you’re planting in a drought-prone area, opt for drought-tolerant perennial plants or consider installing an efficient irrigation system.

5. Garden Space: Consider the size and shape of your garden, as well as the available plantable space. Avoid overcrowding by selecting plants that will grow comfortably within the allotted space.

6. Plant Height and Spread: Some perennials are taller or wider when they reach maturity. Keep in mind the height and spread of each plant to ensure they fit harmoniously in your garden design.

7. Bloom Time and Color: Choose plants with varied blooming times and complementary colors to create an appealing visual landscape throughout the season.

By taking these factors into account, you’ll be well on your way to creating a stunning, low-maintenance perennial garden that you can enjoy year after year. Happy planting!
