True Organic Prilled Sulfur – Organic Fertilizer for Better Plant Growth, Flowers, Vegetables, and Herbs – Lowers Soil pH – 5lb Bag Covers 1,333 Sq. Ft.

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.

I have really enjoyed this product. As an organic backyard gardener, I struggle to find products that: 1) are actually quality products. 2) Organic. 3) Made in the USA is a big bonus for me! I have been using this for my leafy vegetables and my corn and boy have I seen amazing growth using this stuff.I love that my kids can help me use this product (supervised) and I don't have to worry about what they are handling. There is next to no smell and no dust from this product. Easy to use! Would love, LOVE to try more products form this brand.

It not the sulfer I was after but this is definitely good stuff. Note: there's this and then there's an instant kind of sulfer I can add every 2 weeks. This stuff you add to the medium soil prior to planting and it last the entire season. I'll use this stuff for the start of my growing season. I'll add it one time prior to planting my plants. I am surely looking forward! Thank you. Blessed filled Gratitude!

It works well but smells bad. In my pots and outdoors I don’t notice, but I cannot use it in my hydroponic garden.

Great fertilizer, it reminds me of my grandparents' homemade compost. Easy to use and a little goes a long way. Makes my plants happy, makes me happy, will definitely buy again!

This is good product

I used this in the soil around my blueberry bushes as the native soil was just a little too alkaline. The blueberries were more prolific and larger after lowering the pH.

Good for plants
