"Augustine and his team did a great job on my 35 year old redwood tree and an apricot tree. They arrived on time, trimmed the trees as I expected, and did a great job cleaning up."

"I interacted with Adrian (co-owner), Joe (co-owner), Eric (foreman I think), and Cassidy (front desk). In the first step of contacting them after I got a flier in the mail, it was easy to get ahold of them and set up a time, no hassle. Cassidy was very charming and endearing to speak with. Then I met with Adrian about the bid and he was helpful and informative when I inquired about the health of the trees and how I could support their health (same with Eric). Joe and Eric came to actually carry out the work for the project and they were both pleasant to speak with as well. They were also easy-going, helpful, and organized with their work force. I could see they all worked hard to get the job done (and there was a lot to do). I wasn't able to engage with Joe as much, but when I spoke with Eric, he was informative, patient, and thorough in his occupational execution as well. Did a good job cleaning up too! I greatly appreciate their service, and here's another thing on my check list I can mark off and be relieved about!"

Arborists questions, answered by experts

Maple trees start the growing season by developing small groups of red flowers where the tree's fruit, the samaras, will appear in the coming weeks. Later in spring, the samaras, which many call whirlybirds or similar names, develop into single-winged seed carriers that spin when falling or drifting in the wind. 

Service costs depend on several factors, including the system's age, type, and size, as well as the complexity of the repair. Labor costs and whether replacement parts are necessary also play a significant role.

If executed correctly your tree should survive after being transplanted to a new spot. However, effective transplanting requires six months, careful root pruning, safe transport to the new location, and replanting in prime soil conditions. You’ll also need an appropriately sized root ball for a complete tree transplant. A good rule of thumb is that, for every inch in diameter, your tree’s root ball needs to be around 11 inches. So a tree with a diameter of six inches needs a root ball of approximately 66 inches.

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.

Only trim palm trees as needed, which is usually about once per year. However, don't stick to that schedule if the palm tree doesn't need it. Avoid trimming palm trees when possible. It’s best to trim palm trees only when you notice a buildup of dead fronds. That said, leave the brown fronds during the dormant season because this organic matter helps protect the tree from the cooler weather.
