Customer Reviews
Decent experience, took a while
I ordered the Soil Test Kit and some 12-12-12 Starter Fertilizer. The ordering process on the website was straightforward enough, no real issues there. Shipping took about 7 days to get to me in Arizona, which felt a little slow for a small box, but it arrived in good condition. I used the soil test, results came back in about 10 days, and they were pretty detailed. The fertilizer bags were well-sealed. Overall, a solid product experience, just wish delivery was a bit faster.
Good deal on fertilizer
I was looking for some good quality fertilizer that wouldn't break the bank. Found a bundle deal on the Flagship Fertilizer and it saved me a bit compared to buying bags separately. Shipping was also free since my order was over $75. Felt like I got decent value for my money and the lawn is looking better already.
Love my new lawn!
I'm so happy with my purchase from Yard Mastery! I got the Kentucky Bluegrass Seed and some Humic12. My lawn was looking pretty rough before, but now it's growing in thick and green. The instructions were easy to follow and everything came really well packaged. I'm definitely buying from them again for my fall application, and I've already told my neighbor about their products. My grass never looked this good before!
Yard Mastery Community Discussion
Share tips, ask questions & help fellow shoppers save more
Heard about Yard Mastery but also looked at Sunday Lawn Care. Is Yard Mastery actually better, or just different? Worth the price difference?
Does Yard Mastery ever do any sales besides the big holiday ones? Like, is there a spring kickoff sale or anything for the growing season?
Hey guys, thinking about getting some of the fertilizer and maybe a soil test kit from Yard Mastery. Is their stuff actually good quality? Like, real pro grade or just marketing hype?
Can you use more than one promo code at checkout? Got a new customer thing but also seeing a military discount.
Trying to figure out shipping times. I'm in central California. If I order a big bag of the 12-12-12 this week, how long before it gets here?
