Customer Reviews
Always reliable for lawn care
I've been using Jonathan Green products for years now. I've bought Black Beauty Sun and Shade, and more recently the Winter Survival Fall Fertilizer. This latest order for the fertilizer was just as smooth as always. The delivery was on time, and the product quality was consistent. It's why I keep coming back, they just work for my lawn.
Good seed, fast shipping
Ordered Black Beauty Ultra Grass Seed. It arrived in 3 days. Seed looked good, started growing quickly. Happy with the purchase.
Decent products, shipping delays
I bought the Mag-I-Cal Plus for Lawns in Acidic Soil along with some Black Beauty Ultra. The ordering process on the website was straightforward enough, no issues there. Shipping took 7 days to reach Denver, which was a bit longer than I expected for a standard delivery. When it arrived, one bag of Mag-I-Cal had a small tear, but the contents were mostly intact. I used their soil pH test kit first, then applied the products. The grass seed is germinating well so far, and I think the Mag-I-Cal is helping. Customer service responded within a day when I emailed about the shipping time, which was good. Overall, the products seem solid, but they could improve their delivery speed.
My lawn looks way better
So I decided to finally do something about my patchy lawn, you know? My neighbor told me about Jonathan Green. I got the Black Beauty Heavy Traffic seed because my kids and dog are always running around. Ordering was super easy online. It got here pretty fast, like 4-5 days. I spread it out and boom, my lawn actually looks decent now. It's way thicker and greener. Totally worth it, I'm glad I tried it out.
Mixed feelings on delivery
I recently ordered the Love Your Soil and a Hand-Held Spreader. The products themselves seem good quality, and I've heard good things about Love Your Soil for improving compacted areas. The spreader felt sturdy enough for small jobs. However, the delivery took closer to a week than the 3-5 days estimated, which was a slight inconvenience as I had planned to apply it over a weekend. Everything arrived undamaged, thankfully. The pricing was fair for what I got, especially compared to some local stores. While I'm happy with the items, the longer shipping time was a minor downside.

Anyone know if they ship to California? And what's shipping usually like, quick or does it take forever?
Thinking of trying the Black Beauty Ultra. Does this stuff really grow in fast? I need to reseed a patch pretty quickly.
