Beat the Heat with These Summer Gardening Tips

Summer Gardening Summer gardening tips

Summer is here, and the temperatures are rising, but that doesn’t mean your garden has to suffer! With a little planning and the right techniques, you can keep your plants healthy and flowering all season long. In this guide, I’ll share my top tips for thriving in the heat as a seasoned gardener. From choosing heat-tolerant plants to watering wisely, you’ll learn everything you need to know to create an oasis that looks as vibrant in August as it did in May. Let’s get started!

Select the Right Plants

When it comes to summer gardening, plant selection is key. Not all flowers and vegetables can handle the scorching sun and lack of rain. Instead of frustrating yourself with failures, focus on varieties bred to bloom in the heat. Some good options include:


  • Zinnias: These cheerful blooms come in an array of colors and hold up well in direct sun.
  • Marigolds: With their bright orange, yellow and gold hues, marigolds are a classic for border plantings.
  • Petunias: For trailing vines or containers, petunias pump out color all season.
  • Sunflowers: Nothing says summer like a backyard full of towering sunflowers.


  • Salvia: With spiky flower clusters in shades of red, blue and pink, salvias attract hummingbirds.
  • Daylilies: Low maintenance and drought tolerant, daylilies come back year after year.
  • Astilbes: Fluffy plumes of pink, red, or white make astilbes a beautiful choice.


  • Tomatoes: Cherry and grape tomatoes are more heat-tolerant than larger varieties.
  • Squash: Zucchini, yellow and pattypan squash thrive in warm conditions.
  • Peppers: Hot peppers like jalapeños stand up to the heat better than bell peppers.
  • Beans: Pole beans climb supports out of the hot sun.

By choosing plants adapted to your climate, you’ve already taken a big step toward success. Take the time to research what grows best in your area.

Prep the Soil Properly

The soil is your garden’s foundation, so it’s important to prepare it well before planting. Good drainage is essential in summer to prevent wilting and root rot issues caused by wet feet. If your soil is clay-based or compacted, work in organic matter like compost, aged manure or peat moss to improve its structure. This allows air and water to penetrate more easily.

You’ll also want to test your soil’s pH and nutrient levels. Most flowers and edibles thrive in slightly acidic to neutral soil between 6.0 to 7.0. If it’s too alkaline or acidic, amend with the proper materials, like sulfur or lime. And don’t forget to feed your soil – a well-balanced, slow-release fertilizer applied before planting will give seedlings a healthy start. Taking the time for these preparatory steps will set your garden up for success all season long.

Use Mulch Wisely

Mulch is your garden’s armor against the hot sun. It moderates soil temperatures, conserves moisture and suppresses weeds. The most effective mulches for summer are organic options like shredded bark, leaves, or grass clippings. They break down over time to enrich the soil. Inorganic mulches like gravel also work well but don’t offer the same benefits.

The key is to apply mulch thickly, around 2–4 inches deep. This creates a protective barrier while still allowing air to circulate below. Be sure not to pile it right up against stems, as this can lead to rot issues. And never use mulch that contains dyed wood, as the chemicals could harm plants. Properly mulched, your garden patch will stay much cooler and require less watering through the dog days of summer.

Water Wisely

During hot spells, plants can go through water quickly. But overwatering is just as bad as underwatering, so it’s important to water judiciously based on conditions. As a general rule:

  • Water deeply but infrequently, about 1–2 inches per week if it hasn’t rained. Light, frequent watering encourages shallow roots.
  • Water in the morning if possible, as evening watering can lead to fungus issues.
  • Use soaker hoses or trickle irrigation for a slow, deep drink without wasting water. Overhead sprinklers are inefficient due to evaporation.
  • Check soil moisture with your finger before watering. If the top few inches are dry, it’s time to quench your garden’s thirst.
  • Group plants with similar water needs together to water zones efficiently.

With a little observation, you’ll get a feel for how much your particular garden requires on any given day. Adjust as weather patterns change to keep plants hydrated without overdoing it. Proper watering is key to thriving in the heat.

Fertilize Wisely

While plants require nutrients to flower and set fruit, too much fertilizer can actually damage or kill them in hot weather. During the heat of summer, go light on the Nitrogen (N) and opt for a balanced, slow-release formula high in Phosphorus (P) and Potassium (K) instead. These nutrients promote blooms, root growth and drought tolerance.

Avoid high-nitrogen “quick release” fertilizers, as the excess can burn roots. And don’t overdo it – follow package instructions carefully. Too much of a good thing is still too much. As with watering, observe your plants and only feed as needed based on how vigorously they’re growing. Fertilize in moderation and your garden will thrive without stress.

Provide Afternoon Shade

On the hottest afternoons, even heat-loving plants can wilt. To keep your garden perky through the dog days of summer, consider adding some dappled shade. Umbrellas, pop-up canopies or shade cloth stretched on a frame all work well. Just be certain the shade fabric is breathable, so air can still circulate.

You can also try planting shade trees or tall perennials on the west or south side of your plot that will block the fiercest sun rays without casting too much gloom. Remember: plants still require some sunlight to photosynthesize. The goal is to take the edge off, not create deep shade. A little afternoon relief can make a big difference to your garden’s health.

Practice Pest and Disease Control

While a healthy, thriving garden is less prone to issues, pests, and plant diseases can still rear their ugly heads in summer. Stay on top of problems before they get out of hand with regular inspection and preventative care. Some effective strategies include:

  • Remove diseased plant debris promptly to prevent spread.
  • Practice crop rotation to avoid buildup of soilborne pathogens.
  • Use row covers or insect netting barriers against flying and crawling pests.
  • Spot treat with organic, targeted remedies like neem oil or insecticidal soap.
  • Release beneficial insects like ladybugs, lacewings or predatory mites for natural control.
  • Consider resistant varieties when available to prevent recurrence of issues.

Being proactive and addressing potential difficulties early pays off down the line with a stronger, more productive summer garden.

Enjoy Your Bounty!

What should I do if my plants are wilting on hot afternoons?
Provide some temporary shade using umbrellas, shade cloth or trees/shrubs until conditions cool off. Be sure plants still receive a few hours of sunlight and check soil moisture: often wilting is due to lack of water rather than heat alone.
How often should I water my vegetable garden?
Frequency depends on weather patterns, soil type and plant needs. As a general rule, water deeply 1-2 inches per week, or whenever the top few inches of soil are dry. Check soil moisture regularly with your finger and adjust watering up or down based on conditions. Overwatering can damage roots as much as underwatering.
What's the best way to control pests organically?
Prevention is key - maintain healthy plants, remove diseased material, and practice crop rotation. For specific pests, try targeted remedies like neem oil, insecticidal soap or releasing beneficial insects. Row covers also block many flying and crawling insects. Regular inspection allows you to address small problems before they spread. With an integrated approach, you can enjoy an effective organic pest management plan.
