Versatile for field crops, orchards, greenhouses, and hydroponics, this product offers multiple use options. For best results, follow these guidelines: Soil application—20–60 lbs per acre pre-plant or at planting; banded or side-dress—10–30 lbs per acre; for improved results, combine with at least 50 lbs ammonium sulfate per acre.

Let customers speak for us
Plant was well packed and shipment was very fast. Received a very nice fully rooted plant in the pot!
The organic garden soil is doing very well in my garden bed. The company was professional, nice, and accommodating to my needs. They provide many types of things for your landscaping at a reasonable price.
Product was delivered promptly and the quality of the product was very good, as hoped for. I was thrilled to receive the product so quickly! Thank you!
Product is great. Didn't care for having to pay am extra $17 tariff to UPS to get it delivered, but I guess that's not your doing. Thank you Mr. President.
My new babay arrived safely and only lost two little leaves so far. The first one I ordered from different shop arrived with two leaves attached that fell off within ten minutes of unboxing and 22 leaves that had came off during shipping. So glad she arrived looking as beautiful as i was hoping. Also had a surprise red arrow syngonium cutting that’s beautiful. Also customer service was amazing. Will definitely order from them again. Hoghly recommend this shop.
Great flag and it works well on our hangar ceiling. A little worried it wouldn't arrive in time for our event but it did.
Enjoyed putting them together
I think I’m in love! This beauty came delicately packaged. Seemed to have no stress at all from shipping. I live in Miami, I was worried about shipping all the way from California. To my surprise she arrived well taken care of already. I can tell this grower takes pride in caring for these babies. Shipping was fast. I just ordered again same day!
Great service and great product. Delivery was quick. Good communication.
lovely olive jar, attractive to keep on display. And useful too.
Fast delivery . Product exactly matches description. Easy to contact with same day replies. We will use them again.
Great job from growing to shipping
