What is wrong with my tree(My husband says it's a disease)?

Question

The leaves are mostly green and healthy(as they should be), but today I noticed, there were some leaves a "rusty red" color. it's not possible that it's it's dying, because I've watered it everyday since I got it. Is this some kind of disease? I don't know what kind of tree it is(sorry, I'll update this if I found out though). I live in Portland, Oregon, so it's not sunny and dry. What's wrong with it?

Answer 1

Living in a wet climate (Portland, OR), you might actually be OVER watering your new tree if you are watering it everyday.  I'll wager that more new trees and shrubs are lost from over watering them (killing with kindness) then by under watering.  

I'm in Lincoln, NE.  We haven't had a meaningful rainfall in about 6 weeks now and I'm only watering my new trees once a week at most.  I'll put a trickling hose near the base of each for several hours at a time.

Check the soil around the tree, it should be moist, not saturated.  Tree roots need to breathe.  If you saturate the soil you collapse all the pore space out of it, which means there's no room for air.  

Try backing off on the watering and see what happens.

Answer 2

Okay, sounds as though it's a tree you recently bought.  Take some of the brown leaves back to the place where you bought it and ask them what's causing it.  Somebody there ought to be able to help you.

Answer 3

i have been doing gardening for 10 years and i have never seen a tree that needs to be watered everyday. not small, not big. it does sound like a disease. i would recommend you to water less frequently. it hard to tell you how much without knowing the kind and size of the tree. i hope this helps a little.  

Answer 4

In your area of the country "rust" is a problem.Its caused by high moisture caused by high humidity and low sunlight.and above normal rain. even over watering. Rust infestations will become apparent  usually in mid to late August. Keep all the fallen leaves picked up and tossed or burned to help keep from spreading it further.Check with you local agricultural (county extension service).They will be glad to look at a sample of the leaves and direct you from there. Good Luck--oh be sure to put sample leaves in a zip lock bag.
