Summer 15% Discount on fertilization and treatments. We are a full-service tree care company providing tree maintenance and plant healthcare solutions for your property. Our main focus is to provide our clients with a professional, modern approach to tree health. Award winning.

"This is a combination of a 5 star and a 1 star review for Tree Pros, I figure that averages out to about a 3 star rating - you can decide for yourself. TLDR: They did a great job doing the work they showed up for, but never actually finished the job and ghosted us. THE GOOD: I hired Tree Pros to take down two large Tree of Heavens (Ailanthus), remove a grove of Ailanthus, trim two trees overhanging the house, and trim and treat an Ash tree. One of the Ailathus was very close to the house (overhanging it quite a bit), the other was near the street. They did an excellent job removing both of them. They also did a great job trimming all trees and (I assume) a good job treating the Ash. They treated the Ailanthus stumps with Tordon to stop them from sprouting up more, which worked well. They seemed experienced dealing with Ailanthus... which if you've ever dealt with them, they are a HUGE pain to get rid of (see Tree of ****). Tree Pros' quote was reasonable compared to others I got and they were responsive when scheduling the job. We did run into a bump about a week out from our scheduled date when I asked the city (Englewood) to confirm Tree Pros' insurance status. Tree Pros was not registered with Englewood, and an arborist/company must be to do business within city limits. I informed Tree Pros of the issue and they had it worked out within a couple days and we still hit our target date. Overall, no big complaints here. Their staff are friendly and knowledgeable and they did a good job. THE LESS GOOD: This is where the 1 star review comes in. Part of the quote I received from Tree Pros was to subsequently have the tree stumps ground down- we needed to wait 4-6 weeks to let the Tordon effectively kill the Ailanthus stumps, and they said they'd reach back out to schedule an appointment for stump grinding. They originally cut the trees down on 6/22/2022 and 6/23/2022. Come 8/6/2022 (just over 6 weeks), I hadn't heard anything back from them about scheduling the stump grinding, so I reached out. They emailed me back 2 days later stating they would schedule it. I reached back out August 19 (two weeks later) requesting a status. They got back to me August 20th saying they would schedule it. We called and left a voicemail. No response. Eventually, I gave up and hired a different company to do it, because it seems like Tree Pros doesn't care to finish up the job. That being said, I did not pay up front for the stump grinding, so I'm not out any money on them ghosting me, just a bit of added frustration to an otherwise pretty good experience. So, take my experience for what you will, but I personally don't think it reflects well on a company when they bail on the last part of a job. Given this interaction, I would not hire them again and will not be using them for recurring treatments on my Ash tree or to plant a new tree where one was removed."

"I hired SavATree to Re-Shape and remove dead branches from a 40 foot Ash Tree in my front yard.. There were 10 foot dead branches above the crown.. A crew of 3 showed up in just a few hours had my ugly tree go through a complete transformation ... The Sawyer was a Very Nice Lady named Rebecca, she was a Master with her chainsaw.. Her and her two Colleagues were Friendly, Knowledgeable and Very Hard Workers.. After they ran all the excess branches through the wood chipper and cleaned up all the debris..

Lawn Fertilization and Treatment questions, answered by experts

In most cases, it is worth paying for professional lawn care. DIY lawn maintenance is possible, but it can get extremely time-consuming, especially to make your property look well-maintained. Not only is lawn maintenance time-intensive, but it can also get expensive, even to DIY, especially considering the cost of fuel and maintenance for your lawn care tools. Professional lawn care services average around $100 per service, making it a relatively inexpensive investment, especially for how much time it saves you.

You can thicken new grass by using fertilizer, watering it 1 to 1½ inches per week, mowing when it is at an optimal height, and preventing weeds. You should fertilize your grass while you plant the grass seed, or soon afterward. Use an herbicide to prevent weeds or spot spray with herbicide to kill existing weeds.

Make your ryegrass thicker by boosting soil health. Add organic matter, aerate the lawn if the soil is compacted, fertilize appropriately, and see if your lawn needs dethatching. Your local lawn care service can come and look at your lawn and provide specific advice and remedies for your lawn issues.

You should water your lawn two or three days before putting down fertilizer to ensure it can properly absorb it. It's good to apply fertilizer if the ground is moist, but you want to avoid overwatering or flooding the area because it can prevent the grass from absorbing the nutrients. Consider weather conditions when scheduling your fertilizer treatment and read the instructions to see how long you should wait to water after application.

Fertilizing is optional after dethatching. However, the period immediately after dethatching is generally considered the best time to fertilize your lawn because the thick debris is now gone. As a result, applying water and fertilizer as the final steps of dethatching can help to spur incredible growth.
