Summer Gardening Guide: June

Location: Georgia | Zone: 8a/8b

While the calendar says summer officially starts on June 21st, anyone living in Georgia knows the "scorching" truth: summer arrived weeks ago! As the May mildness fades into the heat of June, our focus at Old Oak Homestead shifts to one of the most powerful tools in a gardener’s belt: succession planting. By staggering your crops rather than planting everything at once, you ensure a steady, continuous harvest instead of an overwhelming surplus. It’s the best way to optimize your space and keep younger, more resilient plants growing all season long.

Master Your Summer Gardening Succession Schedule

• Continue planning for your fall and winter garden.

  
  

• Start planning out your succession planting schedule.

  
  

• Take a tour of your garden looking for places where you can intercrop allowing you to place more successions. This is really effective for small garden spaces.

• Experiment with different varieties and planting dates, observing how each crop performs under varying conditions. This hands-on approach not only enhances your gardening skills but also fosters a deeper connection with the land and the cycles of nature. As we embrace the heat of summer, let us remember that with careful planning and execution, our gardens can continue to flourish, providing us with bountiful harvests well into the fall.

  
  

• As the soil warms up, and the days become longer, ideal conditions are created for planting a variety of vegetables and herbs. This is the perfect time to sow fast-growing crops such as radishes, lettuce, and heat tolerant spinach, which thrive in the summer heat.

  
  

• Take advantage of the warm soil to plant second crops of slower-growing items like squash, cucumbers and peppers, ensuring that there is always something fresh to harvest from the garden.

• Make a plan for what you will do if you need to provide shade for you plants.

  
  

Summer Gardening Preparedness and Maintenance

Summer gardening in Georgia is as much about maintenance as it is about planting. To keep your homestead productive through the heat, focus on these core pillars:

• Swap, Don’t Stop: When spring plants pass their prime, pull them immediately. Having transplants ready to "plug and play" into those empty gaps ensures your garden space never stays idle.

  
  

• Fuel Growth: Summer crops are heavy feeders. Beyond initial composting, side-dress your plants with fresh compost or use a compost tea foliar spray to give your successions the nutrition they need to grow steadily.

• Armored Soil: Keep your soil covered! A 2-3 inch layer of straw or aged wood chips acts as armor against the sun, locking in moisture and suppressing weeds. For the best results, run your drip irrigation under the mulch to deliver water directly to the roots.

• Smart Irrigation: In the June heat, consistency is everything. Aim for at least 1 inch of water per week, preferably in the early morning. A quick "finger test"—poking the soil 2-3 inches deep—will tell you if your plants are actually hydrated or just surface-wet.

• Harvest to Multiply: The more you pick, the more they grow! Regularly harvesting tomatoes, squash, and cucumbers prevents the plant from "shutting down" and encourages it to keep producing fruit all season long.

Garden Tools and Supplies

As we move into the intense heat of July and August, providing "relief from the reach" of the afternoon sun becomes your garden's top priority. High temperatures and prolonged UV exposure can stall growth or even scorch your plants. Here is how to create a cooler microclimate on your homestead:

• Harness Natural Shade: Take a walk through your garden in the late afternoon. If you have trees on the property, use those naturally dappled areas for more sensitive crops. The filtered light helps soil retain moisture and prevents leaf scald. This is worked of us. We get afternoon shade from the trees around the garden, giving much relief from hot Georgia sun.

  
  

• Vertical Trellising: Use your tallest crops to your advantage! Planting sun-loving corn or sunflowers on the southern side of your beds creates "living shade" for smaller, more delicate greens growing beneath them.

• Shade Cloth Solutions: For wide-open areas, shade cloth is a lifesaver. Look for a 30% to 50% density—this blocks the harshest rays while still allowing for essential airflow and pollinator access.

• Temporary Fixes: Don’t be afraid to get creative! Outdoor umbrellas, pergolas, or even simple burlap screens can be moved around to provide instant relief during 90°F+ heatwaves.

• Microclimate Grouping: Group plants with similar water needs together. When they grow in a dense "canopy," they naturally shade their own roots, keeping the soil significantly cooler than exposed dirt.

Succession Seedlings and Natural Pest Control

Succession planting is only as good as the plants you have waiting in the wings. To keep your garden beds full and your pest pressure low, focus on these two essentials:

• The "Plug and Play" Method: We always keep a fresh tray of seedlings ready to go. The moment a spring crop is spent or shows signs of disease, pull it! Having a transplant ready to take its place immediately fills that gap, preventing weeds from moving in and keeping your harvest timeline on track.

• The Hardening-Off Process: Don't rush your indoor starts into the Georgia sun. About 7 to 14 days before planting, begin placing your transplants outside in a sheltered, shady spot for an hour or two. Gradually increase their sun exposure each day. This "tough love" strengthens their cell walls, ensuring they don't wilt or go into shock once they hit the garden soil.

• Enlist a Beneficial Crew: In June, the best pest control isn't a spray—it's an ecosystem. By planting heat-loving flowers like Lantana and Marigolds alongside your vegetables, you invite predatory insects (like ladybugs and lacewings) to do the work for you. Look for flowers with open, accessible nectar to keep these "good bugs" hanging around all summer.

Companion Planting: June’s Perfect Pairs

Vegetable	Companion Flower/Herb	Why they work together
Tomatoes	Basil & Marigolds	Basil improves tomato flavor and repels flies; Marigolds deter root-knot nematodes and whiteflies.
Squash & Zucchini	Nasturtiums & Oregano	Nasturtiums act as a "trap crop" for aphids and repel squash bugs; Oregano provides a thick ground cover to trap moisture.
Cucumbers	Dill & Cosmos	Dill attracts predatory wasps that eat cucumber beetles; Cosmos bring in pollinators to ensure better fruit set.
Corn	Sunflowers & Beans	Sunflowers act as a physical barrier against wind; Beans fix nitrogen in the soil that hungry corn plants crave.
Peppers	Basil & Petunias	Basil masks the scent of peppers from pests; Petunias repel asparagus beetles and leafhoppers.
Melons	Marigolds & Mint	Marigolds protect the shallow roots from soil pests; Mint (in pots!) helps deter aphids and ants.

What to Sow and Plant in June

Direct sow - Early June

If you’ve already started these crops, consider this your next round of succession plantings. If not, don’t worry—there is still a perfect window of opportunity to direct sow! Just a tip: when planting heat-resistant lettuce or spinach, be sure to take extra steps to keep the soil cool so they can thrive in the June sun.

• Beans (Snap and Limas)

• Cucumbers

• Edamame

• Okra

• Heat resistant lettuce

• Heat resistant spinach

• Melons

• Summer Squash

• Watermelon

• Winter Squash

• Pumpkins

• Cover crops such as cowpeas or buckwheat are good choices for empty beds. We like to choose a variety that will not reseed and can be easily terminated.

  
  
  
  

Transplant - Mid June

Using transplants for succession planting is a game-changer for extending your season. We prefer this method because the tricky germination phase happens early and indoors, meaning your plants are strong and ready for the soil the moment a spot opens up. For example, starting corn inside ensures a head start, guaranteeing a harvest before the first frost hits.

• Lettuce

• Heat Resistant Spinach

• Melons

• Corn

• Summer Squash

• Spaghetti Squash

• Winter Squash

• Watermelon

• Spaghetti Squash

• Sweet Potato Slips

Herbs

Herbs and Flowers

In June, the Georgia humidity really begins to settle in. To keep your garden looking vibrant and your kitchen well-stocked, it’s time to focus on "heat-seekers"—plants that don’t just tolerate the high temperatures, but actually thrive in them.

Sun-Loving Summer Blooms

If you want a garden that stays colorful even when the thermometer climbs, these varieties are your best friends. They are resilient, drought-tolerant once established, and magnetic to local pollinators:

• Sunflowers & Zinnias: The quintessential summer duo. They love the full sun and provide excellent height and structure to your beds.

  
  

• Marigolds & Cosmos: These are workhorses in the garden. Marigolds help deter certain pests, while Cosmos offer a delicate, airy look that softens the garden landscape.

• Lantana, Pentas, & Celosia: These are true heat-warriors. Lantana and Pentas are butterfly favorites, and Celosia adds unique textures and "flame-like" colors that won't fade in the sun.

  
  

The Summer Herb Garden

Most Mediterranean herbs adore the June heat, provided they have well-draining soil. This is the peak time to get your aromatics in the ground:

• The "Big Three": Basil, Oregano, and Thyme love the warmth. Frequent harvesting of basil actually encourages it to grow bushier, so don’t be shy with the pruning shears!

• Woody Perennials: Rosemary and Sage are incredibly hardy. Once their root systems are established, they can handle the Georgia dry spells with ease.

• The Shade-Seeker: While most herbs want full sun, Cilantro is the exception this late in the season. To prevent it from bolting (going to seed) immediately, tuck it into a spot that receives afternoon shade and keep the soil consistently moist.

By choosing plants that embrace the humidity rather than fighting it, you’ll enjoy continuous blooms and fresh, fragrant harvests all the way through the peak of summer.
