In 1938, Concentrates began as a buyer's co-op for local farmers, farm supply stores and feed mills who wanted to take advantage of their combined buying power. The original Concentrates co-op members were primarily buying "Feed Concentrates", which are the different feed ingredients needed for livestock to provide additional minerals, energy, and salts to their base diet of forage and grains.
Pallets of 50 pound bags would arrive via train car, and Concentrates staff - in those days known as "the Ant Boys" - would unload them by hand. Fast forward a few decades, and Concentrates grew to be the largest wholesale distributor of Organic fertilizers on the West Coast.

From small garden needs to larger farming needs... Concentrates is always my first stop. I head there for chicken feed, chicken scratch and oyster shell. When I’m starting my seeds I always start here; seed starting trays, soil and all the amendments that will ensure a bumper crop. For the past two years they have also been the place I choose for soil when it comes to growing cannabis. Their prices are fantastic, they have tools & tips and so much more. You won’t find everything you need here but you’ll be glad you stopped in, saved some serious $$ and supported a locally owned business in

Great store, lots of good amendments and feed and growing mix components are the best price anywhere. It's pretty convenient to southeast Portland.
It's cool that they have loose amendments and feed supplements and cover crop seeds so you can buy only what you need when you don't need an entire sack.
Employees have always been friendly, and usually are knowledgeable. The one time I would have wished they were more knowledgeable was when I was buying waterfowl feed and they couldn't tell me anything about how to use it for baby waterfowl so they wouldn't choke (I ended

Heather and Zach have assembled a team of knowledgeable, passionate and friendly people who listen and have recommendations for you. I have a Certified Organic Apple Orchard North of Vancouver and their recommendations have been very helpful over the years. It is a drive from North of Vancouver but the experience is worth every mile.

I've been a customer of Concentrates since they were in inner SE Portland, and have always loved this store. Since they moved to Milwaukie, I found myself going there less often-and after today, that will change-to FAR more often! Money is tight, as it is for everyone, and we have what amounts to a small farm with chickens and over 1000 sq ft of garden. While they garden saves us money, it takes money to keep it going strong, and Concentrates has all the amendments, fertilizers, and seeds I needed for a significant savings over the farm stores in Portland. AND they sell broken bags of various

The place is a little tricky to locate. Luckily, I called prior to making the trip & the automated phone recording gave detailed directions. Super knowledgeable, helpful, friendly, respectful staff. I'm still fairly new to gardening & my thumbs are a long way from green! It was nice to be able to ask my beginner questions (that may otherwise seem like common gardening knowledge) w/out fear of judgement.

I was referred to Concentrates because of their quality and customer service. I called for an item and was helped by Kayla. Talk about above and beyond! She gave us great directions and even stood outside to help the quickness due to us having such little time. She was so outstanding, all I can think about is how to pay it forward from her kindness. Businesses need to start acting like these great people again! I’ll refer anyone to them. Their products speak for themselves.

I love Concentrates Inc. I've been a customer since they were right by the railroad tracks just south of Division, before they were in the red and white building down the street. I loath their new location in Milwaukie, it's a 17 mile drive from my home in NE, and I will never understand why they didn't move to NE near the 205 bridge, for all that Clark county business. I wish they put their current inventory on their website, because 17 miles is a long way to drive to see if they have something in stock, for I often go there early and can't call first. Yet, I love Concentrates

Hard place to find but it is in the Gramark Business Park. That is East of Bob's Red mill retail and then a bit North back always. Literally tons of anything and everything you would want for gardening organic or non. This is the place for variety and moderate sized bags to huge bails.
I came by to look at worm castings at a better price then my typical retailer and left with a bag for much cheaper.
Very friendly and helpful service I would highly recommend anyone who has a moderate to large size garden project to come on by

I have purchased sodium bicarbonate and Organic compost on two separate occasions from this store and I am very happy with the prices and the product. The last time I was there someone volunteered to help me load my car and as a woman who just had a c-section this kind of customer service was much appreciated.
However, there is one woman that works there that can make going to Concentrates a very unpleasant experience. I'm not sure if she feels threatened by other women or she is just plain rude but they need to fire her immediately. She barely looked up from her computer when I went to

Google Maps kept telling me I'd arrived at my destination, but I couldn't find it! Concentrates is hidden up the drive behind the commercial building along the street. Head back and park inside the gated area to the far right. It might seem like it's not a parking area, but it is! They had an interested selection of herbs and other starts (feverfew, yarrow, aponia, etc).
I was here for supplies for my hens, but being an avid gardener I *had* to check out their gardening supplies. They have a thorough stock of large bags of coco fiber, pumice, peat, 4-way-mix and a number of organic

Been going there faithfully since they relocated to the Milwaukie light industrial park area. Always found the organic feed and and plant nutrients to be good quality at a fair price. The two young men working the retail side were curious and always more then helpful. They actually looked up information if they didn't know the answers to my questions.
Lately there has been an older woman working there that is less then curious and always chatting with the other workers but seems very short in temperament when customers have a question or when I needed help loading feed. I dislike going in

Great selection of garden amendments, many are available in bulk so you don't have to buy a 25-40 pound bag if you don't need to. They sell organic fertilizer but you can make your own custom blend and save a little bit per pound over the prepackaged options. They have a small seed rack and various small animal feeds.
Check out the online price list/ inventory sheet. I love this! It is great to be able to plan out your shopping from home and have an idea what it will cost.
They now carry a line of heavy duty hoes, I bought a couple for Father's Day, they seem to be good quality

I went to a talk that Heather gave, and it was great. She is friendly and knowledgeable. I later went to Concentrates to follow up on her recommendations about amending soil. She wasn't there, but the workers that were there acted like they were too cool to talk to me. I think I ended up getting what I needed, but I left knowing I'd keep going back to Portland Nursery, one of the 7 Dees, or Garden Fever. I can't speak to the deals that other reviewers mention, mostly because how often do you need to buy a 50 lb bag of cottonseed meal? Saving a couple of dollars isn't worth

I'm not an organic farmer or a gardener (yet), but we do have animals - housecats, to be precise. Concentrates has been our connection to great value on our shrinking budget for some time now. We get most of our cat food (Sportmix is a good brand that nourishes the kitties and goes a long way) and Kozy Kitty litter is a good basic clumping litter that doesn't break the bank.
It may strike you as odd to go to an Ag vendor for household products but Concentrates has What You Need™ at a good value. At least give them a try.
If you go, say "hi" to Tiny, and see if you can&apos

I'm always on the lookout for pro spots that sell special items to the general public for cheap. Bonus for good customer service and providing advice.
I came across Concentrates because they promote urban chickens. The front counter person, Heather, has even written a pamphlet about it.
They have more soil amendments than I knew existed: crushed oyster shells, rice hulls, organic fertilzer in dozens of varieties, non-organic fertilizers - as many, chicken feed. Very helpful in Portland's hard pan clays that otherwise excel in growing weeds. You can get an idea from the retail product

No one has reviewed this place?!? Oh my word. Urban gardeners, and heck, every gardener I am yelling out to you. THIS PLACE HAS WONDERFUL DEALS! They sell in bulk, and also in smaller sizes.
For instance I got:
-A box of 4lb Black Gold organic fertilizer and
-2 cu ft (56.6 L) Black Gold waterhold cocoblend potting soil (OG)
That's what I mean by small
