What wrong with this tree?

[BigCountry101]

Bought the house about a year ago. There was a branch that leafed out, then turned yellow, then brown, then just kind of curled up and died.

Same branch is doing it again this year and it seems to be spreading. Any ideas what's going on?

What is chlorosis?


The visible sign of yellow leaves is the result of limited chlorophyll formation. Deficiencies of minerals–iron (most common), zinc, magnesium, and/or copper are the cause of chlorosis. Although the soil may not be lacking in these minerals, there are several factors that contribute chlorosis:

• Very wet weather
• Poor drainage
• Heavy, compacted soil
• Alkaline soil, making it more difficult for your tree to absorb certain minerals
