"M&N Stump Grinding and Small Tree Services is now OUR tree service people. We switched tree services because we were tired of replacing sprinkler heads, turf and cleaning up after theycleaned up. M&N was unbelievably good. It was amazing to have a service with such professionalism along with the quality of work. They did an amazing job of cleaning up afterward. Like I said, they are now our go to for all our trees. So thankful we went with them. Shout out to M&N - your good, very good!"

"D&D Tree Testimonials About us Gallery Contact D&D Tree Tree Service Open today until 7:00 PM GET QUOTE Header image for the site TESTIMONIALS a week ago Hired these fellas to grind down a number of aspen stumps. They were ontime, diligent in their work, cleaned up afterwards and price was reasonable. I recommend them. ? - Rocky i 3 months ago They did an excellent job on our fence! I would highly recommend this company. - Kathy M 12 hours ago Daniel was responsive and accommodating from the first phone call! Once Daniel and his crew arrived with all the equipment they needed to remove 3 large pines, and a dead ash, we knew we chose the right company. Every single gentleman that worked at our house was professional, funny, and so obviously well experienced. Watching the teams work was like watching a symphony, they were all in tune with each other, and anticipated the other guys moves. They were very detail oriented, and worked so hard to protect all the areas that needed to be. They took every scrap away, and left the job site almost better than before they arrived. We are so pleased, and will definitely hire them again! We have more trees, and definitely landscaping that needs to be done! Thanks to ALL of you for an exciting Saturday, and a super job well done! Jocelyn and Alvin"

"My neighbor had 5 trees removed by them. Watching them work I realized I was watching professionals. I hired them to have 3 very large trees removed from my property and was happy with the work both in speed and price. I will be using them from now on for all my tree service."

"Hernandez tree service was phenomenal. They were timely, presentable and overall good to work with. They did a removal of a large dead tree. As well as a trim on a smaller tree. The dead tree removal was in between my house and the neighbor's house and there were zero problems. They worked swiftly and accurately. I would highly recommend for any tree services you may need."

"Top-Notch tree service has really lived up to its name every time I've used them. They've trimmed trees for me as well as taking out trees that unfortunately had to go. Their people are extremely skilled at what they do and have taken on Jobe requiring a huge crane to complete. I've literally never been concerned about any aspect of what they advised needing to be done."

"Glenn did an awesome job on clearing a berm with a large cherry tree stump and MANY shoots, as well as a juniper bush. The berm now looks as though nothing ever lived there. His pricing is very competitive. In fact, he charged me only about a 1/4 or what another tree service wanted. Wonderful! Would definitely recommend Kingsley Stump Grinding!"

Arborists questions, answered by experts

It’s not always easy to tell when a tree is dying, although signs like dropping branches and brittle bark can sometimes offer clues. It can also be difficult to know whether a tree is dead or dormant, especially if it’s a deciduous tree. You’ll want to wait until a growth season to get a good idea of a tree’s health. When in doubt, contact an arborist for a consultation.

In most cases, you should not use a pruning seal on trees after trimming. Applying a sealant can interfere with the tree's natural healing process, and it does not guarantee protection from pathogens. Instead of sealing the cut, the best practice is to support the tree's natural recovery by providing it with plenty of water and a dormant-style fertilizer. However, there are exceptions. Pruning seals may be recommended for very vulnerable species, like elm trees, in areas where dangerous diseases such as Dutch elm disease are prevalent. In these specific situations, the protection offered by a sealant can outweigh its downsides. For advice tailored to your situation, especially after cutting large branches, it is best to consult a local tree trimming professional.

Your neighbor is not in a good position to know if your trees are truly dead or pose any kind of danger. That’s why hiring an arborist or tree service expert can be such an important part of the process. If the trees are still alive and don’t pose any threat, you’re in the clear (but you may want to document and photograph everything in case events turn sour down the road).

But if a tree is visibly dead and near the property line, you should remove it to be safe. If a dead tree falls on a neighbor’s property, they may have grounds to sue for negligence. If any branches on trees have died, it’s a good idea to cut them back for similar reasons.

Unfortunately, if you cut the top off a palm tree, it will die. Instead of budding or branching out, the top begins to slowly rot. That's why having a professional tree trimming at least twice a year is a good idea. If you don’t have experience with trimming your palm tree, you might accidentally cut the top off, leaving a dead and rotting tree in your wake.

A chainsaw is the best tool to cut down a tree, but you may also use a handsaw or ax. You may also want to use a lopper or pole saw to remove limbs before cutting down the tree. Wear chainsaw chaps and protective gear, including eyewear and earplugs if you use a chainsaw. Again, if you’re unsure about how to use this tool, this project may be one to skip.
