True Organic Seabird Guano – Rocket Fuel for Flowering
True Organic Seabird Guano is the real deal. I added it to my compost tea and—no exaggeration—my flowers responded immediately. We’re talking perked-up leaves, tighter node spacing, and a noticeable boost in aroma within 24 hours. It’s like the plants knew they were getting something special. This stuff is potent but clean. No funky smell, no clumps—just pure, high-phosphorus magic straight from the sea cliffs. It brews beautifully into a tea or top dresses well with other amendments. I’ve used a lot of guanos and bloom boosters, but this one’s a standout in both quality and performance. If you’re serious about stacking dense, resinous flowers that hit their full potential, True Organic’s Seabird Guano belongs in your lineup.

Very Potent Stuff
Its a wicked good, slow acting, nitrogen nutrient, for any plant. Comes in a big bag, lasts awhile and is safe, clean, and comes with application instuctions.

Black gold for your garden—no BS (just worm poop 💩
I’ve used plenty of fertilizers, but these worm castings? Whew. My plants perked up like they just got a pep talk from Mother Nature herself. The soil feels fluffier, holds moisture better, and my roots are thriving. Tomatoes are popping off, and even my picky flowers are showing off. What I love most? This stuff is all-natural and doesn’t stink like synthetic junk. It's pure worm magic, slow-release nitrogen that keeps things fed for weeks. Whether you're mixing it into beds or sprinkling it into transplants, it’s stupid easy to use. If your garden needs a glow-up, give the worms their flowers. This stuff works.

Easy was to care for your plants.
I am still learning about how to take care of plants and have more of a green thumb and less of a brown thumb so I appreciate this product. It’s easy to use and not toxic for the environment, which is also a huge plus. It’s simple to dilute. I literally just put an ounce of it in a half gallon milk jug and shake it up. It’s very dark and smells pretty strong. But overall, it’s very easy to use and my plant are enjoying it so far. I just propagated this Pothos and fed it with this product and it seemed to perk up a bit more than usual afterwards. .

Good Product
Good size and value for the cost. Bag is durable. I have nothing bad to say about this product. Worked well this growing season.

Just what my plants needed
Easy to administer, the smell will be off putting but good for the plants. If using on indoor plants, be aware of the smell, it can be overpowering.

Great
I use this in my homemade potting medium. My plants thrive. I also sprinkle some in the hole of outdoor plants prior to planting. It’s good stuff. There is no smell, my plants are super healthy, and they grow like weeds. I’ve never had any plants get burned roots. It also helps my Hoyas bloom.
