If you’re tired of ineffectively mixing fertilizers or potting soil ingredients together in a wheelbarrow or tractor bucket, let us do the dirty work for you.
Buy ingredients from us or bring your own. To estimate volume requirements for products sold by weight: dense products like rock powders are about 1 yd/ton, while fluffier products like crustacean meal are about 2 yds/ ton. To convert other volume measurements: there are 27 cu ft or about 700 dry qt per cu yd.
IMPORTANT NOTES:
Our rates assume mixes contain ten or fewer ingredients; we may charge more for complex mixes or materials that are particularly difficult to handle.
Please allow at least two weeks for completion, including for pickup orders.
While custom blends do not incur extra shipping charges, we do charge our regular shipping rates for the included materials. If you purchase your ingredients from us, our website will correctly display your shipping charges for shipments under 8000 lbs. For larger shipments, or if you are supplying the ingredients, please contact us for a freight quote.
