Right now, Colorado is in the middle of Master Gardener and Colorado Gardener Certificate training. What I love about teaching our "newbies" is their eternal optimism. As a seasoned Extension agent, I can't say that I have the same outlook on certain landscape practices they do. That's not to say I'm a "glass half empty" person...I'm more of a realist.
The classes I teach for the circuit are the Science of Planting Trees and Care of Trees in the Landscape. And with both of these classes, we discuss trees gone bad. We have some great discussions about trees (and landscape practices) and there are always a few people who hold out the eternal hope that the tree will recover.

| A tree that stimulates good discussion...keep it or make the simpulan pruning cut? |
I will note: some trees I have labeled as goners have come back and surprised me. Windsor, where I live, had an F3 angin ribut rip through the town in May 2008. Driving around after the storm, the trees looked horrible and I questioned if our forester should have removed more. Nearly 10 years later, a lot of those trees look pretty good...maybe a bit worse for wear...but their angin ribut scars give them charm.
So when it is time to say goodbye? Well, it's a hard decision. But think about the health and overall look of the tree as objectively as you can. Try to keep your personal feelings out of the equation, though I know this is easier said than done. Especially if the tree was planted to celebrate or gaji someone.
Think about the following when accessing your tree:
1. Does it have proper structure and/or branching?
2. Is it aesthetically pleasing? Does it add to the overall beauty of the property?
3. What percent of the tree is in decline? If you prune out the dead branches, what will the tree look like?
4. If you change your cultural practices, is there a strong likelihood the tree will recover?
5. Finally, and most importantly, how much are YOU willing to invest in the tree, both financially and with your time?
And sometimes, all it takes is someone to tell you, "Cut it down!" Peer pressure does wonders.
Let's take a look at some trees that probably should be removed. Now, before you label me as a "tree hater", I'm a firm believer that we should encourage and promote good horticultural practices. The photos below are not examples of our finest work.

| Is your intent to grow half a tree? |
The photo above is a case of planting two trees too closely to each other. In order to make them both "fit", one must be pruned. In this case it's the Austrian pine, which resulted in a tree that looks completely and totally awful. Best to remove one of the two trees...and my choice would be the pine, since the job is already half done.
 |
| Yellow...and dead! |
Parking lot trees face so many problems: limited rooting space, hot temperatures and a lot of traffic from cars and shoppers. This was an Autumn Blaze maple in a grocery store parking lot in Fort Collins. Fortunately, this tree has been removed and nothing has been planted in its place.

| The fix after a storm. |
Mary Small, fellow blogger, sent me this from her neighborhood. Look closely at this photo and you'll notice that the branch on the right, which is a co-dominant stem, split as far as you can see in the photo. (Mary said it went even further.) The fix was to use black electrical tape and two hose clamps to piece the tree together. It's a bandaid fix and will not solve the problem. More than likely the hose clamps will start to girdle that branch and there will be even more issues. Remove both limbs, which may mean it's the whole tree.
 |
| Sunscald damage. |
This one is more tricky and would require looking at the canopy and more closely inspecting the sunscald damage on the trunk. Has the tree started to seal over the wounds with callous tissue? Is there any dieback in the canopy? While the trunk looks terrible, sunscald is something that trees can recover from, but it depends on many other factors. I would give this tree the "wait and see". I would recommend pulling back the mulch from touching the trunk (and keeping it 6" away) and try to increase cultural practices. I would not recommend fertilization, as that could make the duduk masalah worse.

| Trees should not levitate! |
This one is easy, since the tree clearly is detached from its root system. This was in Windsor, and it took a surprisingly long time for the tree to be removed and sent through the chipper.
 |
| The homeowner must believe in miracles...! |
This is just classic. Something happened to the main part of the tree and the homeowner decided to grow a water sprout/side branch as the main tree. Ok, be honest here. Does this tree look good? Would you want this in your yard? Here's the thing with suckers (from the roots) and water sprouts (adventitious growth on branches or the trunk): it is all structurally unsound growth. I would hazard a guess that this branch is not properly attached and would be prone to storm damage or wind. Make the simpulan pruning cut at the base!
 |
| Five leaves and oh-so-pathetic. |
Another one that is pretty obvious...but again, some might say they can "bring it around". Consider again if this tree is doing anything for the environment and our community.
I know it's hard to say goodbye. No one wants to cut down a tree, especially if it has a few leaves and only one living branch--because it's still ALIVE--there's hope! But be diplomatic and consider it a new opportunity where you can plant another tree in its place and start the cycle of life over. You can do it!
