Is my tree dying if it has yellow leaves?

Not necessarily. It is often a sign that the tree is stressed by its environment, which is usually fixable.

Should I fertilize immediately?

Only if you are sure it is a nutrient issue. Over fertilizing a stressed tree can actually make the problem worse.

Siberian elm: yellow leaves, causes and fixes

Check these first

Check the soil moisture level 3 to 4 inches deep.
Look for signs of standing water near the trunk.
Examine the leaves for patterns of yellowing.

Likely causes

Overwatering
Most likely
How to tell: The leaves turn yellow and may feel soft or limp. The soil around the base of the tree stays soggy for days after rain.
What to do: Adjust your watering schedule to allow the soil to dry out slightly between waterings. Ensure the area around the tree has good drainage and is not sitting in a low spot.
Nutrient Deficiency
Possible
How to tell: Leaves turn yellow while the veins remain green, often indicating a lack of iron or nitrogen. This usually happens in alkaline soils.
What to do: Apply a balanced, slow release fertilizer designed for trees in the spring. If the soil pH is too high, add elemental sulfur to help the tree absorb nutrients better.

When to worry

Occasional yellowing of older leaves is normal as the tree cycles through foliage. If the entire canopy turns yellow or leaves drop prematurely, it is a sign of stress.

Stopping it coming back

Water deeply but infrequently to encourage strong roots. Avoid piling mulch directly against the trunk to prevent moisture buildup.
