Community Help draft our FAQ: How to become an arborist

4 Upvotes

It helps to join the International Society of Arboriculture (ISA), your local ISA chapter, and your state arborist association. This helps you get to know other people working in the industry, and when they have known you for years, and know your work or at least of your work, they will feel comfortable verifying your experience.

Attend as many trainings as you can get, participate in the training Q&As, and collect the associated continuing education credits.

ISA membership is independent of any ISA credentialing, so if you know you want to get ISA credentials but you are not yet eligible, joining ISA can help you become eligible sooner.

All of this makes you more employable, at higher pay, and safer on the job because you are more likely to recognize dangers. You will learn to recognize best practices.

Had to post here. I went to a friend's house they just purchased and the previous owner installed fake grass and burned the hell out of this ash tree (I think). $1,500 to remove and $3,500 total to remove and place a Chinese Pistache.

I used to pass this tree on my mail route every day, and I always wondered what happened here. When I asked the residents about it, they said it was already there just as it is when they moved in. So, any ideas from you guys?

Weeping willow advice

Thumbnail gallery
26 Upvotes

I looked through a bunch of past posts and most people were asking about newly planted weeping willows. We just moved into a 13 year old house with a 13 year old weeping willow which I wish wouldn't have been planted. There are large exposed roots with some heading towards the concrete pad under the deck. We plan to be at this house for a long time. In 20 years, I don't want to regret not tearing this out when we first moved in. It does provide shade to the west, but would you all just keep it or tear it out now? I'd likely replace it with a maple or two.

Should I have this Bradford Pear removed asap?

I know these are horrible and are infamous for splitting. I’ve let it do its thing for the 8 years I’ve owned the home. It has lost some large limbs in the past 2 years, during storms.

It provides so much shade in what feels like summer 3/4’s of the year and there is greenway access on the other side of neighbor so it helps keep some level of privacy with all the foot traffic.

But I do suspect the gap in middle is getting wider so it’s only a matter of time. I’m shocked it hasn’t split yet considering the size of it. A good number of my neighbors have had there’s split long ago…ones half the size.

How risky is it to have a large tree transplanted? Any recommendations on a stable alternative, that would thrive with less than ideal drainage and NC soil? Something that won’t bring on some new population of weird or invasive insects, preferably.

This tree scares me

What do you guys think of this tree in my backyard? It makes me kinda nervous. It’s got a decent lean to it and the trunk/ roots look questionable to me. It’s constantly dropping twigs/ medium branches and occasionally large branches. About two months ago that huge branch in the picture broke off, about 15” in diameter.

Quaking Aspen

Post image
7 Upvotes

Hello, I have (what I believe is) a mature quaking aspen in the corner of my yard. It is absolutely gorgeous but also located next to the only spot that will work for a garden on my property. Is there any way to control the shoots/saplings and prevent/discourage them from growing up through a garden, or is that only possible with tree removal? I really want to use the space directly in front of it for a vegetable garden. Any advice is appreciated. TYIA!

Is 3500$ reasonable ?

6 Upvotes

About a month ago, a downburst went through my senior parents’ neighbourhood in southwestern Ontario and knocked down several trees, including their approximately 30-year-old linden tree.
They hired an arborist/tree company about three weeks ago and were charged $3,500 to remove the tree. They removed the entire tree and took all of the linden wood away with them rather than chipping it on site. I had actually asked whether we could keep a couple of pieces of the wood, but everything was taken, and I’m not sure what happened with it.
What they did leave behind was the large, upturned stump/root ball. The roots are still sticking vertically out of the ground and it’s a substantial piece. My parents are seniors and aren’t physically able to deal with it themselves. I’ve tried cutting some of the roots down with a Sawzall, but I haven’t been able to make much progress. It’s also large enough that their small dog can get underneath it.
Another thing that concerned us was the payment. My parents were asked to write a personal cheque payable to the owner personally rather than to the company. We’ve since been trying to get a receipt/invoice for the work, but the company has been difficult to reach. They keep saying they’re too busy, and the arborist recently hung up on my brother when he called asking about the receipt.
Unfortunately, I don’t have a photo of the remaining stump/root ball right now, but I’m hoping to get one.
For those familiar with pricing in southwestern Ontario, does $3,500 sound like the going rate for removing a storm-damaged linden of this age/size, hauling away all the wood, but leaving the entire upturned stump/root ball behind? Is leaving the root ball like this normally considered a completed removal, or would you generally expect dealing with it to be part of the job?
I’m concerned that my senior parents may have been taken advantage of, but I’d really appreciate hearing from arborists about whether the price and the work completed sound reasonable.

Advice wanted - Cut trunk off-shoot or not

Thumbnail gallery
1 Upvotes

This is located in Brisbane, QLD, Australia

The tree is a Melaleuca linariifolia as far as I know and we've had it for 2 years

It's been steadily growing an off-shoot and the sagging is causing the other trunks to sag hence the stake. I've read I should cut this off but would appreciate additional advice and if cutting is the right option, any tips to ensure I don't accidently damage the main trunk. This tree is growing with my daughter, so it's precious to me. Thanks

Japanese Maple girdled root??

Thumbnail gallery
3 Upvotes

I have this old mature Japanese maple tree that has a potential girdled root that I found when exposing its roots flair as it was buried way to deep for who knows how long the root grew over a small rock so there is a big enough gap that I can fit 3 fingers underneath the root so it’s not growing into the tree yet / girdling it but if I leave it alone for any longer I’m worried it will start to choke out the tree slowly any opinions or ideas if I should cut it this winter or when ever I could thanks for any help in advance:)

Frass buildup at base of large maple

As title states, have recently observed buildup of sawdust-like frass at the base of our large (silver?) maple tree. Entry bore holes and presence of ants, including large black carpenter ants are evident. What’s our next step to prolong the tree’s life?

Is this tree able to be saved?

Thumbnail gallery

We had a storm recently and the wind broke a major trunk of our tree and we discovered larvae of some kind boring inside of the tree. We are unsure of the species. I reached out to our local 4H extension office for identification/advice but they weren’t any help. Unfortunately we don’t have any arborists in the area that do treatment on trees, we just have people who safely cut down trees. We are in northern Indiana if that helps identify the type of beetle/larvae. Any advice is appreciated. It is sadly our biggest, most central tree and I am so sad it is not doing well.
