Rich, Organic Boost for My Chunky Soil Mix 🌿🌱
I’ve been adding these organic worm castings into my chunky soil mix, and they’re a great natural fertilizer. The texture is rich and clean, and it blends in easily with coco chips, perlite, and charcoal. It gives the mix a nutrient boost while still keeping everything airy and well-draining. I love that it’s organic and natural — safe for my houseplants and perfect for giving them an extra kick of slow-release nutrition. My plants have responded really well so far, with healthier leaves and stronger growth. The bag size was perfect, exactly what I ordered. ✅ Why I love it: -Clean, high-quality worm castings -Blends easily into chunky soil mixes -Adds nutrients without compacting the soil -Organic and safe for houseplants -Great complement to coco chips, perlite, and charcoal ⚠️ Cons: -None — it’s exactly what I wanted Overall, this is an excellent soil enhancer and a must-have for anyone who mixes their own potting blends. It’s now a staple in my repotting routine. 🌿

Works great for growing sweet potatoes!
This was my first year growing sweet potatoes from slips. Apparently sweet potatoes grow best in nitrogen depleted soil so they can focus energy on root growth (i.e., the sweet potato itself, not the greens). I didn’t notice any smell to this bone meal. I applied 2 tablespoons around each slip at soil level roughly every 2 weeks and watered it in along with 1 tbsp all purpose fertilizer. I noticed beautiful sweet potato flower blooms that attracted all kinds of pollinators to my garden! The bees loved it! For my first year, I’m really happy with my harvest! I chose this specific bone meal product since the brand is well-known to me. Great quality, also it just happened to be a reasonable price. Win-win. I still have some left over for next year’s planting.

Good quality, and good quantity for the price
I usually mix some perlite and pine bark into the potting mix they sell at the big box stores to improve drainage and aeration of the soil. You don't need too much of either - less than 10% of the total amount of soil. My many house plants are happy.

Really Helps my Plants
I love this brand and am a repeat customer. My vegetables especially my tomato plants love this stuff. I am currently growing several indoors and they love it. It comes in a 5lb bag which is a good amount. This is great addition to add to fertilizer regiment for plants. The quality is on par with other pricier brands.

Good.
Was able to use it well for my home plants for this winter. Easy usage and organic content. Longevity noticed. Was able to retain moisture when gone for days out.
