Top 5 Heat-Tolerant Trees You Should Plant in Your Garden

Summer is getting hotter, and gardeners everywhere are noticing that some trees just can’t keep up with rising temperatures. If you want a garden that thrives even in the heat, choosing the right trees is essential. Heat-tolerant trees not only survive high temperatures but also provide shade, beauty, and sometimes even edible fruits, making your garden more enjoyable during the hottest months.

Here’s a look at five top trees that can handle the heat while bringing charm and function to your outdoor space.

• Water moderately until established; once mature, it tolerates drought well.

• Prune in late winter to maintain shape and encourage blooms.

2. Crape Myrtle (Lagerstroemia indica)

Crape myrtles are heat lovers that add vibrant color to any garden. Their long summer bloom time makes them a favorite for gardeners who want consistent beauty through the hottest months.

3. Olive Tree (Olea europaea)

Olive trees aren’t just for the Mediterranean—they’re perfect for hot gardens with sunny conditions. Their silver-green leaves add texture, and mature trees can even produce olives if the climate allows.

3. Do heat-tolerant trees need special soil?
Well-draining soil is key. Most heat-tolerant trees do best in soil that doesn’t stay soggy, though some can adapt to a variety of soil types.

4. How do I keep my heat-tolerant trees healthy during extreme heat waves?
Mulching around the base helps retain moisture, and deep watering during prolonged heat can keep young or stressed trees healthy.
