Walnut trees are impressive, long-living giants that offer valuable shade, stunning fall foliage, and—of course—delicious nuts. But before your tree grows tall and productive, it needs the right care in its early days, especially during its first summer. Heat, drought, and transplant shock can all set back progress if not addressed early.

Here are five essential things you should be doing this summer to help your young walnut tree root deeply, grow steadily, and avoid seasonal stress.

1. 💧 Prioritize Deep, Infrequent Watering

Walnut trees develop deep root systems—but those roots need time to get established:

• Give the tree a slow, deep soak once or twice a week, depending on rainfall
• Allow the top couple of inches of soil to dry out before watering again
• Avoid frequent shallow watering, which encourages weak surface roots

💡 Use Soil Moist Transplant Crystals at planting time to help retain moisture around the root zone and reduce stress in between waterings.

2. 🍂 Mulch Makes a Big Difference

Mulching isn’t just about looks—it’s a performance booster for newly planted trees:

• Spread 2–4 inches of mulch (shredded bark, pine straw, or composted leaves)
• Keep mulch several inches away from the trunk to avoid rot
• Mulch helps maintain moisture levels and soil temperature and blocks weed growth

🌱 A well-mulched walnut is a happier, faster-growing walnut.

3. ☀️ Shield Young Trees From Extreme Heat

Walnuts enjoy full sun, but newly planted trees can be sensitive in their first summer:

• During heatwaves (90°F+), provide temporary shade cloth or use nearby plantings for dappled protection
• Container-grown walnuts can be moved to a partially shaded spot during peak heat
• Wilting or scorched leaves are signs your tree may be overheating

🛡️ Protecting young trees now sets them up for stronger sun tolerance later.

4. 🐛 Keep an Eye Out for Insect Activity and Leaf Issues

Stressed trees are more vulnerable to pests and disease:

• Check leaves weekly for signs of aphids, walnut caterpillars, or blight
• Prune off damaged or diseased leaves and dispose of them
• Use organic treatments only if needed—don’t overdo it

🔍 A five-minute inspection once a week can prevent major setbacks.

5. 🚫 Avoid Fertilizer Until the Tree Is Settled

Feeding your tree too soon can actually hinder its progress:

• Skip the fertilizer during midsummer
• If you didn’t fertilize at planting, hold off until early fall
• Let the tree focus on root strength, not rapid growth

🌿 Less is more during the first hot summer.
