It’s a common belief that you should never plant trees during the summer in Texas. While spring and fall are often considered the ideal planting seasons, the reality is that a tree can be successfully planted almost any time of year—even during the hottest months—if it is planted correctly and cared for properly afterward.

Is It Okay to Plant Trees in the Summer in Texas?

The short answer is yes.

The heat of a Texas summer doesn’t automatically prevent a tree from becoming established. In fact, thousands of trees are successfully planted every summer by homeowners, landscapers, municipalities, and commercial contractors across the state.

The key isn’t when you plant the tree.

The key is how you plant it and how you care for it afterward.

Trees Don’t Know What the Calendar Says

Trees don’t have calendars. They respond to environmental conditions.

If a newly planted tree has adequate moisture in the root ball, proper soil preparation, and receives consistent watering during establishment, it can produce new roots throughout much of the year. Root growth often continues whenever soil temperatures are favorable, even when top growth slows.

A tree planted in July with proper irrigation is usually in much better shape than a tree planted in October that is forgotten and allowed to dry out.

The Biggest Challenge Is Water

Summer planting doesn’t fail because of heat alone.

It fails because the root ball dries out.

Container-grown trees have a relatively small root system compared to the size of the canopy. Until new roots grow into the surrounding soil, the tree depends almost entirely on the moisture contained within that original root ball.

During Texas summers, that root ball can dry surprisingly fast.

Consistent watering is far more important than the month on the calendar.

A tree planted in summer will need more frequent watering than one planted in winter.

The goal is to keep the root ball consistently moist—not constantly saturated and never allowed to become bone dry. Soil should be monitored to make sure there is an adequate amount of water, not too wet. Overwareing can be just as detrimental as letting the roots dry out.

Exactly how often to water depends on:

• Tree size
• Soil type
• Weather
• Wind
• Sun exposure

Clay soils hold water much longer than sandy soils, so watering schedules should always be adjusted to actual conditions rather than following a rigid calendar.

Black Nursery Pots Get Extremely Hot

One concern with summer planting is the temperature of black plastic nursery containers.

Black plastic absorbs sunlight extremely well, and on a sunny Texas afternoon the side of a nursery pot can easily reach temperatures of 150°F or higher.

Those temperatures can damage or kill roots growing against the inside of the container wall. Anyone who has removed a tree from a hot black nursery pot has often seen roots browned or dead on the southwest side while roots on the shaded side remain healthy.

The good news is that this problem disappears once the tree is planted.

The surrounding soil acts as insulation, keeping root temperatures dramatically cooler than those inside an exposed black container sitting in full sun.

In many cases, planting the tree actually protects the root system from the excessive temperatures experienced inside the nursery pot.

Proper Planting Makes All the Difference

Whether planting in March or August, the same fundamentals apply:

• Plant at the correct depth, with the root flare visible at or slightly above grade.
• Loosen circling roots if present.
• Backfill with native soil unless site conditions require amendments. This is the best time to add some compost and fertilizer to the soil surrounding the roots. We recommend one part compost to 2 parts native soil with some organic fertilizer mixed in.
• Apply 2–4 inches of mulch over the root zone, keeping mulch several inches away from the trunk.
• Water thoroughly immediately after planting.

These steps encourage rapid root establishment and reduce stress on the tree.

Mulch Is Your Best Friend

One of the simplest ways to improve summer planting success is by applying mulch.

A layer of organic mulch:

• Keeps soil temperatures cooler
• Reduces evaporation
• Conserves moisture
• Improves soil over time
• Encourages healthy root growth

Think of mulch as insulation for the soil.

Avoid Extra Stress

A newly planted tree is already adjusting to a new environment. Avoid adding unnecessary stress by:

• Skipping fertilizer unless a soil test indicates a need.
• Avoiding heavy pruning at planting.
• Protecting the trunk from string trimmers and lawn mowers by maintaining a good ring of mulch.
• Monitoring soil moisture regularly during the first growing season.

The tree’s priority should be root growth, not producing lots of new leaves.

The Bottom Line

While spring and fall generally provide more forgiving weather, summer is not a bad time to plant a tree in Texas.

With proper planting techniques, consistent watering, and a layer of mulch, trees planted during the hottest months can establish successfully and thrive for decades.

The calendar doesn’t determine whether a tree survives.

Good planting practices and attentive care do.

A well-watered tree planted in July will almost always outperform a poorly watered tree planted during the “perfect” season. That’s why successful tree establishment is less about when you plant and much more about how you manage the tree during its first year.
