Services
Soil Conditioning
Report
Drop down Tru-gypâ„¢ Concentrated Minerals after aerating. Tru-gypâ„¢ is a natural soil conditioner that works like millions of tiny hoes to loosen heavy clay soil. Tru-gypâ„¢ improves the fertility and functioning of your soil.
Lawn Thatch
Report
If your lawn deteriorates to the extent that routine cultural practice, such as mowing, fertilizing and watering, do not give the desired response it is probably time to dethatch. By dethatching, it is possible to renew your lawn with out going to the trouble and great expense of completely rebuilding it.
Weed Control
Report
There are a lot of reasons why weeds may be abundant in your lawn and it's often difficult to pin point the specific cause. The best defense against weeds is a good offense! A healthy, hearty, actively green growing lawn will choke out the weeds and resist diseases and insects better than a sparse lawn.
Lawn Aerating
Report
Lawn aeration is the process of mechanically removing soil plugs and small portions of thatch from the lawn. Lawn aeration relieves soil compaction and improves the ability of roots to grow deeper into the soil and expand. The mechanical removal of soil plugs is generally recognized as the best way to improve air and gas exchange, along with water and fertilizer intake.
Fertilization
Report
The best time to fertilize your lawn is right after our aeration service. Holes formed by core removal provide a direct passage way for the fertilizer granules to reach the root zone. It's how we force-feed the lawn! A fertilizing application is included with our aeration service at no extra charge. Fertilizing and aerating is the magic combo for a healthy green lawn.

Last November Four Seasons aerated my lawn, seeded it with Rye grass to keep the yard looking good through the winter until the Kikuya grass could grow back, usually happens by February/March. The rye grass looked great all winter. The Kikuya grass still has not grown back. I believe the aeration went too deep and ripped out all the roots of the Kikuya.

Four Seasons took three weeks to respond to my first call about the grass-less condition in my back yard. They sent out a man this morning to fertilize the yard. He said fertilizer would not bring any grass back. There are no roots to bring back. Four Seasons sent out another man this afternoon to look at condition in my back yard and he says I didn't water enough. I've been watering my back yard, twice a week for 30 years. There's no grass to bring back, no amount of water will bring back grass roots that are not there, they were all removed by an aeration that went too deep. I think you should not use this service. They ruined my back yard. And both men who came out were super rude.

This is the 2nd time I've used Four Seasons Lawn Aeration and am very pleased with their services. We had Matt B. do our lawn and he did a nice job cleaning up and not leaving fertilizer or dirt plugs on our concrete area. They called me about a week before to notify me they would be in the area and to see if I would like my lawn aerated as it was about time. It's approximately every six months they recommended service and they call you to remind you about the time that service is due.

They left the bill at my front door and I pay when I get home. Nice to not be pressured for added services. I wish they could do my backyard but they can't go down that many stairs. You will notice a significant impact on how your lawn will look in about a week. Make sure to water!

I scheduled a aeration service over two weeks ago from Four Season, which was scheduled for today. I got a call last minute mentioning that the person who was supposed to service our lawn, injured his back and they couldn't provide the service today. Totally understand, these things happen and I hope he feels better. However, this is where poor service became an issue.

The next time they could reschedule was in 3 weeks. I asked why I couldn't get in sooner, the women on the phone said they are fully booked and it would be way too much work to call people and reschedule. This is poor resolution to an issue that could have been easily resolved. They provided me a three hour window of time. I am confident they could have fit me in. Now, I am writing a Yelp review which is negative, and I won't stop here.

I was impressed on how easy it was to book an appointment for aerating my yard. They came right on time, did the job and left the invoice on my door! It was so easy and contact less. Thank you!

If you have grass you need this service to make your watering as efficient and economical as possible. This is a top notch company. We have been using them for our residential lawn in Clairemont since the early 90's and they never disappoint. Eric was our technician today, a professional and just a sweetheart.

When Four Seasons Aeration measures your lawn for aeration, they base their prices on measuring "from the air".This is not an accurate measurement and becomes an inaccurate price for their service. They were 3500 square ft and several hundred dollars overcharging for my lawn. When I asked them to come out and do a real on site measurement, they refused. "We cannot be bothered " they told me. "Use another company "-they said I did And unless you want to overpay and deal with people who do not care - You will use another company too

Four Seasons Lawn Aeration provided aeration and reseeding in March. Two and 1/2 months later the lawn started to look bad. I have patchy brown spots and places where the seeding did not take. I have called three times with no action taken to help. I also communicated this to their Permagreen person who said he would note it on their report. Four Seasons Lawn Aeration has not shown themselves to be responsive nor responsible.

Their moto is "Expect A Hole Lot More". This usually translates to "don't expect much"! A $25 up charge for soil conditioner was never approved with my lawn aeration request. When I called the owner to see why that was on my bill she said that the conditioner has already been applied so she can't do anything about cutting me a break on the charge for something I didn't ask for.

Why is it that these small businesses haven't figured out how customer service works if they want to retain their customers. They lost me and the landscaping business that referred me to them.

WOW! These guys are professional, hard working, and know about lawns. Matt and Tom worked tirelessly on transforming our lawn. They even helped us fix a broken sprinkler before they left! Superb service and we'll be doing business with them for years to come! Thanks Dominic, Matt, and Tom!

I highly recommend Four Seasons Lawn Aeration. They showed up on time. the aeration itself was deeper than a company I had used in the past. The machine hit a copper pipe I didn't know about and created a small geyser. My house is older and some of the plumbing is wonky. I had to turn off the water to the house to get it to stop. Four Seasons sent a plumber out in about an hour and a half!

The leak was fixed in about 1/2 hour and the water in the house was back on! NO CHARGE TO ME even though it was not their fault! Accidents happen, but Four Seasons is a PREMIER company. If I could give 10 stars I would.

We have been a repeat customer of Four Seasons Lawn Aeration for almost thirty years! There is no other lawn aeration company in San Diego County that takes such good care of your lawn aeration. They are polite, professional, timely and conscientious. Our lawns have always looked great and lawn aeration helps your lawn remain healthy and also helps conserve water consumption.

Eric showed up right in the time window I was given did a quick walk thru and got right to work with the fertilizer and aeration. He was very personable and happily answered my lawn care questions. Picture below is from right after aeration and watering, will post a follow-up in 3-4 weeks. Can't wait to see the results!

Eric was friendly, on time, efficient and clearly explained what he would be doing. We had our front and back yards aerated, fed and a treatment allied to better hold our watering system. Our dogs safety was of concern to us regarding the lawn food and water retention product. Eric took special time to assure me they would be fine. Eric was thorough and I look forward to having him back. I would recommend your company any time. Thank you

My lawn wasn't soaking in water and I knew it needed to be aerated and fertilized. I found this company online in April, they came out and did a great job. They even follow up so you don't have to remember when to call them. They came out again today and Michael did a great job! Well worth the $60!

And another review! I had Four Seasons out again today for a complete lawn aeration service. Michael did an outstanding job with the aeration and fertilization. Thanks again for a job well done! Additional Review: On 6/15/2018, Michael did a complete aeration and fertilization at my house. The work was performed in a very professional and timely manner.

I will continue to use Four Seasons for my aeration needs. Very quality work. Thanks Lawrence came out to the house on Monday, 8/29/2016. He aerated the lawn, applied fertilizer, moisture management and soil conditioner. Lawrence was very friendly and knowledgeable regarding lawn care. He gave me some good lawn care tips and answered all my questions. I will continue to use Four Seasons and recommend them to my friends. THANKS!

I've been using Four Seasons for a number of years now. They always give a courtesy call to let you know they are going to be in the area, and they always do a fantastic job. Michael Couture was out last time and gave me great information on post care for my lawn.

We've been using this company for at least a decade. They do excellent aerating; very thorough and very deep. It saved our lawn during the drought; and with the recent rains the yard is thriving. We've had MICHAEL the last few times and he is conscientious, clean and careful. We ask for him by name now. We will be exploring their other services. Great value and great customer service.

The photo is our front lawn 3 weeks after Four Seasons Lawn Aeration service it. The lawn is starting to get thick and fill in the patchy areas. It is really looking beautiful. Our lawn front & back get the works from Four Seasons. Michael Couture marks the sprinkles with flags & aerates the lawn. Then he spreads fertilizer & an application of soil conditioner to improve soil development.

Our lawn & soil definitely needs Four Seasons. becausehere is a lot of clay in our ground that makes it hard to water. We are always pleased with the excellent customer care we receive from Four Seasons. Very nice group of folks. We highly recommend Four Seasons Lawn Aeration to everyone.

We have been using Four Seasons for many years now. They provide a great service that helps my minimally watered lawn look good. The drought is tough on water supplies so we water as little as possible. The aeration really helps a lot. Lawrence took care of our yard the other day and took the time to do the job right and answer our questions.

Couldn't be more pleased by the service I get bi-annually from 4 Seasons. Today was no exception. Lawrence arrived on time, gave me tips on caring for my fairly-new sod, did his thing, cleaned up and left.
