Senske Servcies began as a small lawn care and pest control company in 1947 by Bill Senske in Spokane, Washington. During the 1960's, chemical weed and pest control began to grow, expanding the family business. In the 1080's, after four successful decades, Bill Senske handed over the reins to his youngest son, Chris. Chris expanded the family business into new territories including Yakima and Kennewick, Washington. Today, the company headquarters are located in Kennewick, Washington and helps supports all branch functions and growth. Today, Senske has developed quality and competent staff in an array of service areas who can offer residential and commercial services including: lawn care, tree care, weed control, grounds maintenance, pest control, irrigation services, Christmas Decor holiday Lighting, and snow and ice removal. Today, the company continues to strive for superior customer service in which the company was founded upon. Senske operates in the cities and surrounding areas of: Spokane, Yakima, Walla Walla and Kennewick, Washington; Coeur d'Alene and Boise, Idaho; and Salt Lake City and Ogden, Utah, and Las Vegas, Nevada.

"Terrible. The guy was using a broken apparatus and the liquid mix for the injections was pouring onto the ground. I suspect that, because of loosing so much of it on the grounds, the trees did not receive the dosage required. Previous 2 years, not a problem and the bugs were gone. These trees are shade to my deck. Can't get anywhere near them now and Senske will not respond to re-treating the trees. I have emailed and I have called, countless time. No response to emails and calls are always the same story - "It will take 24-48 hours to get a response". Well, it's been lots of those! NOT ANYMORE! TWO and 1/2 YEARS and they're are a train wreck. Faulty equipment, failed services (that you have PAID FOR on your AUTOPAYMENT PLAN) and you can't get a response, at all, over WEEKS. My message to Senske: Maybe y'all should stop the endless office parties and start taking care of your customers. Try answering the phones or the email system that you recommend "Many of our Clients prefer to send an email for a for a Quick Answer On The Go". You never respond to anything, actually. SENSKE SERVICES has no idea what one office is, or any area based service, is doing -- 'SENSKE MOTTO: Let's give ZERO customer response and outlook while we F-around and party while good customers become our former customers.' Looks like a good place to start a new landscape company. Somebody will."

"I hired this company for the season fertilizing of my lawn. On the 2nd application there was a really funky smell all over my lawn and with further inspection I noticed the tech left a giant brown streak 3 feet wide and about 80 yards long all the way across my new asphalt and I also have stains on my brand new hottub. I called the company and they had John the sales person call me. John came out to look and found it very odd and could smell the stench as well. He said he was goin to chat with the owner and get back to me. After a couple weeks of waiting, I finally called back in to see where we were at with it all. John said he spoke with the owner and they dont believe it was their techs that did that and dont plan on doing anything about it... This is the lack of integrity and professionalism you get from this company. Any damage they cause they will just make excuses and deny deny deny. They are the only company that has sprayed my lawn. Completely pathetic that I have to resort to complaints and reviews."

"I had three services done by C&C before I canceled everything. Numerous times, during my quote and all phone calls, I asked them about only coming to do services on Monday or Tuesday as I’m home both of those days. Never did they respect my request for either of those days. They never once provided a courtesy call to let me know when they were on their way to provide any service. I did receive a call a day or two prior to them showing up but they did not respect whether I said yes or no. First they came to apply weed killer and fertilizer to the lawn. They left the weed killer particles all over my patio and walkways. I have a dog so I feel like that was super unsafe for them to just leave piles of it everywhere. Then they came to do some stump grinding. They called the day before to say that they would be coming tomorrow… I called and left a message saying that I wouldnt to be home so I don’t want them to come. They came anyway. No courtesy call prior to arriving ever. They had no care about my sprinklers, which were marked, and they covered it with rocks and ruined the pvc safety around the sprinkler. The final thing was pruning and shaping of my trees and shrubs. This was the worst! During the original quote it was mentioned that it would take about 6 to 8 weeks to perform. At eight weeks I had to reach out to find out if it was ever going to happen… They butchered one of my privacy trees in my front yard. Cut one side up 4 to 5 feet and left the other side touching the shrubs. The shrubs have no shape and look awful. The hedges in the back are uneven. They barely did any pruning of the trees whatsoever. There are still dead branches everywhere. The trees are also resting on the hedges. I did call and state that I was very unhappy for each service. The third and final call is when I asked for all of my future services to be canceled as I am unhappy with the service they have provided. The manager called back and said that they’ll cancel everything pending due to me being unhappy. No attempt was ever made to correct the issues. Never once did they send someone out to even check my sprinklers that they ruined on the stump grinding. When I called and said I was unhappy about the tree pruning and shrubs not once did they offer to come fix anything."

Lawn Fertilization and Treatment questions, answered by experts

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.

If you notice your grass is growing quickly and it’s hard to keep up, cut down on how much you water and fertilize it. Another helpful method is to mow the grass at the highest setting your mower will allow. Mowing at a higher setting slows grass growth since the blades won’t need to repair themselves as quickly if they’re kept at a longer length.

Bahia grass is not difficult to grow, but you might need patience for this slow-growing grass. Whereas some grass species, like Bermuda grass, can take 1 to 2 weeks to germinate, Bahia grass can take two or three times as long, making it seem like it won’t grow. But again, once your Bahia grass is established, it requires little maintenance. Its deep root system makes it a very durable grass that can bounce back after freezes and droughts. 

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.

Yes, it can be cheaper to fertilize your own lawn. DIY lawn fertilization saves the cost of hiring a lawn care company or a company that specializes in lawn fertilization. It’s important to handle fertilizer carefully to avoid the potential dangers of getting fertilizing chemicals on your skin. Also, using the wrong type of fertilizer or misapplying it can permanently damage your lawn. On average, the cost to fertilize your lawn using a professional lawn care service is about $250 and may be worth checking into as professionals tend to have the equipment and knowledge to apply the most effective blend of fertilizer to your lawn for the best results.
