Should the water be removed?

Looking at a live oak and water oak growing together. The customer wants to keep the live oak. Will removing the water oak help or hurt?

The live oak with the tire is to remain. There is also another swing not pictured they want to keep as well. The top of the water oak is in bad shape, but it is not close to the house. Can the 2 trees co exist?
 
I definitely will say the remaining tree will suffer.
How much is dependent on the extent of root grafting and/or root wounding.

Many times the removal of a neighbouring tree just inside of the dripline is enough to set a tree back.
Older trees are more of concern than younger.
I have witnessed this for many years and the best example is right next door to me.
I removed the Silver maple to close to the house and the remaining Norway about 25' away is still struggling with growth and minor diffeciences 3 yrs later on the same side the silver was removed. Both trees about 24 dbh mb 50 years old.
Thats my experience and am quite interested to see what others say.
 
I agree with Ropeshield.if you take away one it can weaken another, trees helps each other get nutrients, and from the picture it looks like they're having a lot of water in the garden,I´m not familiar with the trees but if the live oak dont like too much water around the roots, then it's not good if there is a tree less to drink the water
hope my English is understandable
 
Trees of the same or different pecies support each other physically above ground in several ways. And the root zones of same species trees are often in communication. Trees do communicate with each other. I find that is the coolest thing.
But your comments on the maples and oaks intrigues me. Related but not same species supporting each other. Do you believe this is beyond mere physical wind protection and shading?
 
I love trees, I really do, but doesn't it look like the live oak is half girdled already? What exactly is the prob. with the top of the water oak? I could see some sun scalding issues being a prob. on the live oak since it doesn't appear to have much foliage/sunscreen on the water oak side if you take the wo down. But honestly, I'm not a Phd tree guy, but the situation seems to be death for the live oak at some point if you don't get rid of the water oak. I would think that the water oak would continue to tighten that strangle hold around the base of the live oak. Its an interesting dilema. Are lives and waters close enough familialy (sp?) to graft roots. They are both in the red oak group, right?
 
Hello Greenthumb Pleased to meet you!

Your english is fine.
The water on the ground and the Water Oak makes it a bit confusing. these two points you made may need more clarification.
I understand what you are saying is the Oaks are necessary to transport water and the accumulating water is bad for the Oaks root respiration.
Yes?
 
grafting of roots is high potential within the same genus.
Grafting does occur intergenetically. It is more rare but does happen.
Cool thing that can happen is the cellular material mixes and the growth that occurs will have traits of both.

This is called a Chimera, like a Gryphon or pearple etc.

In this case it would be Live+Water= Wave Oak.
Cool Eh!

Cable and prune? Instead of removal..... they form a pretty neat feature for us humans to live around, and the root systems are symbiotic.... To me... they belong together! :-)
 
Remove one now, or remove one later. The two trees cannot continue to successfully coexist. The will have significant "included bark" issues and subsequent decay development if allowed to remain as they are. It does though look (from the photos) that the water oak would be the one to keep (even if some canopy reduction needed to be done to take care of the damage you mentioned).
 
The water on the ground is result of alot of rain that we have been getting, if fact it rained that morning. The top of the water oak has 3 main branches, 2 of which has major defects.

The customer wants to keep the live oak and I am afraid the the water oak will out grow the live oak and eventually smother it out.

Live oaks are much better trees than water oaks, they live much longer and are much stronger trees. They hardley ever blow over during hurricanes whereas water oaks are a major problem.
 
The live oak will certainly outlive and outgrow the water oak, and will eventually solve the issue on its own. Rushing the process with an immediate removal of the water oak will suddenly place the subordinated live oak in full sun, and subject it to possible sunscald.

Perhaps reduction pruning of the water oak would give the live oak a chance to more quickly prevail in their race for the sun. Once the live oak begins to overshadow and suppress the water oak, you should basically be able to stand back and watch the live oak solve the issue on its own.

The live oak has some pretty significant lean, bow and sweep going on. If it puts out any epicormic growth opposite the direction of the lean, it may be a good idea to encourage growth with good attachments, to cultivate better symmetry in the canopy over time
