In the garden: please identify this tree in my backyard.

In the Seattle area.

Thanks.

Another photo of the tree.

 

Looks like crabapple.

 

One of the Rosybloom types, probably an older cultivar that may become scabby or otherwise fungus infested later in the year.

 

Thanks!

How do you find out it may get fungus infested? In the Seattle area with long and wet winter, how do I prevent this from happening?

 

Older cultivars of Rosybloom crabapples are fungus prone here.
