Pine trees are evergreen, so you don’t expect to see dead, brown needles. If you see dead needles on pine trees, take the time to figure out the cause. Start by noting the season and which part of the tree is affected. This is probably not a normal needle shed if you only see dead needles on the lower branches of a pine tree. Read on for information about what it means when you have a pine tree with dead lower branches.
Evergreen trees provide year-round greenery and structure to landscapes. Seeing brown, dead needles on the lower branches of your evergreen is alarming. This dying from the bottom up often signals a stressed tree. Read on to learn the top reasons an evergreen tree dies from the bottom up and solutions to restore their health.

Common Causes of Needle Browning and Death
There are a few key reasons why evergreen trees show signs of decline on lower branches first:
Insufficient Water
Evergreens need moist soil, especially in hot and dry weather When roots cannot absorb enough water, the tree drops older, lower needles to conserve resources Solution Water evergreens deeply every 7-10 days in dry weather. Add mulch around the root zone to maintain moisture.
Disease
Fungal diseases like cytospora canker infect evergreens, causing resin leakage, wood cracks, and branch death. Infected lower branches die first. Solution: Prune out infected branches. Improve air circulation and spray antifungal treatments.
Pests
Boring insects like pine beetles tunnel inside branches, disrupting water and nutrient flow. This causes needle browning and branch death from the inside out, starting low. Solution: Apply insecticidal soap or remove heavily infested branches.
Insufficient Sunlight
Pine trees love sun, which means lower branches blocked from sunlight may not survive Sometimes shade is a problem for all parts of the pine trees but dead needles and branch death occurs from the ground up Solution You may need to provide your pine trees with more light or plant new pines in a sunnier location.
Natural Causes
As part of their growth cycle, evergreens naturally shed a percentage of older needles each year Lower inner branches also die off when shaded out by upper canopy growth. Solution This is normal as long as less than 30% of needles are affected Prune dead branches for appearance.
When to Worry About Evergreen Decline
Seeing bare branches on the bottom is not necessarily a death sentence for your evergreen. Monitor for other symptoms before panicking:
- Needle drop exceeds 30%
- Multiple branches are dead, not just lower ones
- Entire tree is thinning out, with tufts of needles
- Evidence of pests like bore holes and frass
- Oozing sap, fungi growth, needle discoloration
Significant decline warrants an evaluation by an arborist to determine the cause and best treatment plan. Acting quickly can save the tree.
How to Prevent Evergreen Decline
With proper care, you can keep evergreens healthy and prevent premature needle drop:
- Water 1-2 times per week in dry weather
- Apply mulch around the root zone
- Prune lower branches for better air circulation
- Monitor for pests and diseases
- Fertilize in early spring with a balanced, slow-release fertilizer
- Plant in sites with adequate sunlight
- Avoid wounding trunk and roots
Bring An Evergreen Back From Decline
If your evergreen is struggling, don’t give up hope! Here are tips to nurse it back to health:
- Rule out and treat any underlying pest or disease issues
- Improve moisture with deep watering and mulch
- Remove up to 30% of dead needles and branches
- Fertilize to encourage new growth
- Consider moving the tree to a sunnier location
With prompt troubleshooting and care, many evergreens can recover from early stages of decline. However, if more than 50% of the tree is dead, removal may be required for safety.
Know When To Call A Professional
If your attempts to revive a declining evergreen aren’t working, it’s best to have an ISA-certified arborist assess the situation. A tree expert can diagnose causes and determine if the tree can be saved or should be removed. They have the skills to provide special treatments to rejuvenate struggling evergreens.
Give Evergreen Trees Proper Care
Caring properly for evergreens is the best way to prevent premature needle drop. Make watering, mulching, fertilizing, pruning, and pest management a priority to keep your pine, spruce, and fir trees thriving for years to come. Pay attention to signs of decline and take prompt corrective action. With early intervention, you can get your evergreen back to looking healthy from top to bottom.
Dead Needles on Pine Trees
You planted pine trees in your backyard to add color and texture all year, but the needles don’t always stay a lovely green color. Even the healthiest of pines lose their oldest needles every year. If you see dead needles on pine trees in the fall, it might just be the annual needle drop. If you only see dead needles on lower pine branches or at other times of the year, keep reading.
Lower Branches of Pine Tree Dying
If the bottom branches of your pine tree are dead, it may look like the tree is dying from the bottom up. Occasionally, this may be normal aging, but you have to consider other possibilities too. Not enough light – Pines need sunshine to flourish, and branches that don’t get sun exposure can die. Lower branches may have more trouble getting a share of sunlight than upper branches. Low pine branches may look like they are dying if they have so many dead needles on them that they can’t get enough sunlight. Trimming nearby shade trees may help. Water stress: A pine tree that looks like it’s dying from the bottom up might actually be drying out from the bottom up. Water stress in pines can cause needles to die. Low branches may die from lack of water to make the rest of the tree live longer. Prevent dead needles on lower pine branches by preventing water stress. Give your pines a drink during especially dry periods. It also helps to apply organic mulch over the root area of your pine to hold in moisture. Salt de-icer – If you de-ice your driveway with salt, this can also result in dead pine needles. The lower branches are closest to the salty ground, so it may look like the tree is drying from the bottom up. Stop using salt for de-icing if this is a problem. It can kill your trees. Disease: If you see that the lower branches of your pine tree are dying, it may have Sphaeropsis tip blight, a fungal disease, or another type of blight. Confirm this by looking for cankers at the base of new growth. As the pathogen attacks the pine tree, the branch tips die first, then the lower branches. You can help your pine with blight by clipping out diseased sections. Then spray a fungicide on the pine in springtime. Repeat the fungicide application until all of the new needles are fully grown.
