7 Key to Keep Flowers, Shrubs, and Trees Alive in Georgia

Turn your Georgia garden into a Southern paradise with these tips to keep your plants thriving in the Peach State.

1. Choose the Right Plants

Like a great Southern recipe, choosing the perfect plants for your landscape is all about harmony. Select plants suited for your USDA zone. For those nestled in the northern reaches of the state, consider cool-loving species like flowering dogwood trees and forsythia to grace your garden. As you move south, from the foothills to the coastal regions, explore the rich variety of native plants, such as sea oats and yaupon holly. 

2. Practice Proper Watering Techniques

The Georgia sun is hot, and mastering proper watering techniques is like quenching your garden’s thirst with a tall glass of sweet tea on a hot summer day. Furthermore, the humid subtropical climate changes in an instant, from rainy stretches to dry air. Follow some simple steps to practice proper watering techniques in your Georgia landscape:

• Water deeply: Make your plants more drought-resistant by watering deeply. Additionally, aim to water two to three times per week for 30 minutes, depending on rainfall. 
• Morning sessions: Water in the morning between 6 a.m. to 10 a.m. to reduce evaporation and lower the risk of fungal diseases.
• Target the base: Water the base of your plants, not the leaves, to ensure that the roots receive the moisture.
• Install drip irrigation: Installing a drip irrigation system delivers water directly to your plant roots, ensuring efficient and consistent watering. It also helps combat Georgia breezes and evaporation.

3. Mulch Your Garden Beds

Mulch isn’t just for looks. It is a key ingredient in nurturing a healthy landscape in the Peach State. Georgia’s sunny days are usually scorchers, and your flower beds need all of the moisture they can get. Mulch provides a protective barrier that reduces evaporation and helps the soil retain water. It’s like a cool, shady hat for your plants. 

With the sizzling temps and sometimes cold winters, it is also important to protect your plants’ roots. Mulch also acts as a natural thermostat, keeping the soil cooler in the summer and providing insulation during the winter. 

Weed Control

If all of those benefits weren’t already enough, mulch is also your secret weapon in your battle against weeds. It creates a barrier between the soil and the sun which discourages pesky weeds from taking root. Your garden stays tidy, and you save time that you would be spending hand pulling weeds. It’s a win-win.

Soil Enrichment and Erosion Control

As the mulch breaks down, it adds valuable organic matter to your soil. This enriches the soil, improves its structure, and enhances its ability to nourish your plants. Furthermore, Georgia is no stranger to heavy rains. Mulch also prevents soil erosion by absorbing rainfall, keeping your garden beds intact, and preventing the loss of valuable topsoil. 

4. Enhance Soil Quality

A thriving landscape begins with a solid foundation from the ground up. The quality of your soil is a key player that creates the perfect foundation for your plants. Start by understanding your soil type. Georgia’s soils vary depending on your region, from sand to dense clay. Contact your local agricultural extension office to request information on soil testing in your area to determine your soil’s pH, nutrient levels, and composition. 

Amend as Needed

Now that you know your soil characteristics and its Southern personality, tailor your amendments to your landscape. Soil amendments address a range of common soil issues, including pH, nitrogen, phosphorus, and potassium levels. 

For the Peach State’s dense, clay soils, consider incorporating organic matter like compost to improve drainage and aeration. Furthermore, for the sandy soils of the coast, add organic matter to boost moisture retention. 

Adjust pH

Like most things in life, soil pH is a delicate balancing act. It measures the alkalinity or acidity of your soil. Your soil test results detail the pH level of your soil. Aim for a neutral pH of around 7 for a thriving landscape. If your soil test shows acidic soil, consider adding lime to raise the pH. However, if your soil is too alkaline, add sulfur to lower the pH.

Reduce Compaction With Aeration

Compacted soil is a common problem in Georgia landscapes. It restricts water flow and hinders plants’ access to vital nutrients. Aerate compacted soil to improve drainage and enhance growth using a core or spike aerator. 

The best time to aerate soil in the Peach State is during the growing season when the soil is not too dry or waterlogged in the spring or early fall. 

5. Plant Native Species

Native plants are an important part of preserving Georgia’s biodiversity. They are adaptable and well-suited to the Peach State’s mild climate and potential frost. Additionally, they are low-maintenance and often require less water, fertilizers, and chemicals to thrive. 

Native plants are also an essential source of food and shelter for wildlife, including mammals and local pollinators. Furthermore, their deep roots provide erosion control and reduce harmful runoff. 

Popular Georgia Natives

Check out some popular Georgia natives that will make great additions to your landscape:

• American beautyberry (Callicarpa americana)

6. Protect Plants From Frost

A sudden frost can occur across most of the Peach State. It can damage sensitive landscape plants and even lead to plant death. Frost typically occurs in the winter. However, Georgia has experienced late spring and early fall frosts on rare occasions. 

7 Tips for Frost Protection

Follow these 7 tips to protect your landscape from frost:

• Check the weather: Keep a close eye on weather forecasts, especially during transitional seasons. 
• Cover plants: Cover plants and flower beds with blankets, old bedsheets, or cloth. Ensure the coverings reach the ground to trap heat and prevent frost from settling on your plants.
• Water: Well-hydrated plants are less susceptible to frost damage. Water your garden before a frost to create a heat reservoir in the soil.
• Mulch: A layer of mulch helps insulate the soil and maintain a more stable temperature. This can protect your plant roots from frost damage.
• Re-home potted plants: Bring potted plants indoors during a frost warning.
• Outdoor heaters: Gentle heat sources, such as outdoor heaters or incandescent holiday lights, can help raise the temperature around your plants. However, be cautious when using heat sources to prevent fire hazards.

7. Landscape Maintenance 

Maintaining a charming Southern lawn is a labor of love. Effective landscape maintenance requires a few simple steps:

Regular Pruning and Trimming

Shape your masterpiece with regular pruning and trimming, Prune trees, shrubs, and bushes to maintain their shape. Additionally, be sure to remove dead or damaged growth to encourage new leaves and blooms. 

Weeding and Mulching

Unwanted guests are always a sore sight, but weeds also compete with your garden plants for nutrients and space. Regularly weed your beds to control weeds. Furthermore, apply a layer of mulch to suppress weeds, lower your maintenance, and conserve moisture. As a bonus, the mulch also breaks down, enriching your soil. 

Proper Watering

Ensure that your plants receive adequate moisture. This isn’t always a problem in rainy Georgia seasons. However, the Peach State experiences the occasional dry spell. Additionally, consider installing drip irrigation or soaker hoses to deliver water directly to your plant’s roots and reduce water waste. 

Fertilization

Keep your Georgia natives thriving by providing nutrients. Adding the right nutrients at the right time is crucial for success. Choose the right fertilizers based on your soil test results. Fertilizers contain a label with three numbers representing nitrogen (N), phosphorus (P), and potassium (K). Different plants and turfgrass types require different ratios, Select an NPK ratio to suit your needs. 

Additionally, consider using a slow-release fertilizer for a long-lasting nutrient supply. Quick-release fertilizers provide a rapid nutrient boost, but they are best for specific situations like correcting deficiencies. 

When to Apply Fertilizer in Georgia

Spring and late summer are the best times to apply fertilizer in the Peach State. Apply a slow-release fertilizer in the early spring as your plants enter their active growing phase to replenish nutrient loss from the winter. 

Additionally, flowering plants appreciate a phosphorus-rich fertilizer application in the late spring to promote blooms. Lastly, apply a balanced fertilizer to prepare your plants for the cooler fall and winter temperatures in the late summer. 

Pro tip: For a natural touch, consider using organic fertilizers like compost, manure, or fish emulsion to enrich the soil, improve its structure, and provide slow-release nutrient sources. 

Control Pests and Manage Plant Diseases

Inspect your garden for signs of insects and diseases. Prevention and a proactive approach are your best defenses against these pests. Additionally, consider using environmentally friendly pest control methods to preserve Georgia’s Southern ecosystem.
