Greensboro, North Carolina sits comfortably in USDA Hardiness Zone 7b, offering gardeners a sweet spot for growing a diverse range of plants. With average annual minimum temperatures between 5°F and 10°F, this zone provides a generous growing season that typically runs from mid-March through November. Understanding your local climate and seasonal patterns is the key to creating a thriving landscape that looks beautiful year-round.
In this guide, we’ll explore essential seasonal landscaping tips, top plant recommendations for Zone 7b, and practical DIY advice specifically tailored for Greensboro homeowners.
Understanding Greensboro’s Zone 7b Climate
Greensboro’s climate classification as Zone 7b means you have more flexibility than gardeners in colder regions while avoiding the intense heat challenges of southern zones. The city receives approximately 45 inches of rainfall annually, distributed fairly evenly throughout the year. This consistent moisture, combined with mild winters and warm summers, creates ideal conditions for both cool-season and warm-season plants.
First and last frost dates are crucial markers for Greensboro gardeners. The average last spring frost typically occurs around April 10-15, while the first fall frost usually arrives between October 25-30. These dates serve as your guideposts for planting tender annuals, vegetables, and warm-season grasses.
Spring Landscaping Tasks (March-May)
Spring marks the beginning of active growth in Greensboro gardens. As soil temperatures warm and daylight increases, it’s time to prepare your landscape for the growing season ahead.
Soil Preparation and Testing
Before planting, conduct a soil test through the North Carolina Cooperative Extension. Greensboro soils tend to be acidic clay, often requiring amendments to improve drainage and pH balance. Add organic compost to flower beds and vegetable gardens to improve soil structure and fertility.
Spring Planting Priorities
Early spring is ideal for planting trees, shrubs, and perennials. The cool temperatures and consistent rainfall help new plantings establish strong root systems before summer heat arrives. Consider these spring tasks:
- Divide and transplant perennials like hostas and daylilies
- Plant bare-root roses and fruit trees before they break dormancy
- Direct-sow cool-season vegetables including lettuce, spinach, and peas
- Apply pre-emergent herbicides to prevent crabgrass and other warm-season weeds
Mulch Application
Apply a 2-3 inch layer of organic mulch to garden beds in late spring. This helps retain soil moisture, regulate temperature, and suppress weeds during the hot summer months. Popular mulch options in Greensboro include pine bark, hardwood chips, and pine straw.
Summer Landscaping Tips (June-August)
Greensboro summers bring heat and humidity that can stress plants and lawns. Proper watering and maintenance practices become essential during this period.
Watering Best Practices
Water deeply and infrequently rather than shallow, daily sprinkling. Most established landscapes need about 1 inch of water per week, either from rainfall or irrigation. Water early in the morning (5-9 AM) to minimize evaporation and reduce fungal disease risk.
For lawns, consider letting cool-season fescue go dormant during extreme heat rather than fighting to keep it green. It will recover when temperatures moderate in fall.
Summer Plant Care
Deadhead spent blooms on annuals and perennials to encourage continued flowering. Monitor for common summer pests including Japanese beetles, aphids, and spider mites. Prune spring-flowering shrubs like azaleas and rhododendrons immediately after they finish blooming.
Container Gardening
Summer is perfect for adding colorful containers to patios and entryways. Choose heat-tolerant annuals like lantana, portulaca, and zinnias. Ensure containers have adequate drainage and use high-quality potting mix rather than garden soil.
Fall Landscaping Focus (September-November)
Fall is planting season in Greensboro. Cooler temperatures and reliable rainfall create perfect conditions for establishing new plants.
Tree and Shrub Planting
September through November is ideal for planting trees and shrubs. The soil remains warm enough for root growth while air temperatures cool, reducing transplant shock. Water new plantings thoroughly and continue through winter if rainfall is insufficient.
Leaf Management
Don’t bag those fall leaves. Instead, mulch them with your lawn mower and leave the shredded leaves on the grass. This returns nutrients to the soil and reduces waste. Excess leaves can be composted or used as mulch in garden beds.
Perennial Division
Fall is an excellent time to divide overgrown perennials. Plants like daylilies, hostas, and black-eyed Susans can be split and replanted, giving you free plants for other areas of your garden or to share with neighbors.
Winter Landscape Care (December-February)
Winter in Greensboro is relatively mild, but proper care ensures your landscape survives cold snaps and emerges healthy in spring.
Protecting Tender Plants
While Zone 7b rarely experiences prolonged severe cold, occasional dips into single digits can damage marginally hardy plants. Protect tender shrubs like hydrangeas and gardenias with burlap wraps or frost blankets during extreme cold events.
Pruning Dormant Trees
Late winter (February) is the best time to prune deciduous trees and summer-flowering shrubs. With leaves gone, you can easily see the branch structure and make clean cuts. Avoid pruning spring-flowering shrubs like azaleas and forsythia until after they bloom.
Planning and Ordering
Use winter months to plan next year’s garden. Browse seed catalogs, sketch landscape designs, and order plants from local nurseries. Many specialty plants sell out early, so advance ordering ensures you get your first choices.

DIY Landscaping Projects for Greensboro Homeowners
Rain Garden Installation
Greensboro’s clay soils often lead to drainage issues. A rain garden captures runoff and allows it to slowly infiltrate the ground. Choose a low spot in your yard at least 10 feet from your foundation. Plant with native wetland species like swamp milkweed, cardinal flower, and blue flag iris.
Pollinator Garden Creation
Support local bees, butterflies, and hummingbirds with a dedicated pollinator garden. Include plants with staggered bloom times to provide nectar throughout the growing season. Group plants in drifts of at least three to make them easier for pollinators to find. See our Best Plants for Greensboro NC Gardens guide for specific recommendations.
Edible Landscaping
Incorporate food production into your ornamental landscape. Blueberries make excellent foundation shrubs with beautiful fall color. Fig trees thrive in Greensboro’s climate and require minimal care. Herbs like rosemary, thyme, and sage provide year-round interest and culinary value.
Erosion Control on Slopes
Greensboro’s rolling terrain often includes sloped areas prone to erosion. Plant groundcovers like creeping juniper, vinca, or native green-and-gold to stabilize soil. Consider installing a dry creek bed to manage water flow and prevent washouts.
