The powdered version was more expensive so I bought this one and I just run it through my coffee grinder when I’m ready to use it. It works great and helps add nutrients to my soil blocks mix so my seedlings get off to a great start.

The powdered version was more expensive so I bought this one and I just run it through my coffee grinder when I’m ready to use it. It works great and helps add nutrients to my soil blocks mix so my seedlings get off to a great start. ### ⭐⭐⭐⭐⭐ Very good product, thank you! *by A***R on February 1, 2026* Very good product, thank you! ### ⭐⭐⭐⭐⭐ Using this year in a tomato garden *by J***N on May 18, 2022* I put a small scoop of rock phosphate in the bottom of deep holes to plant my tomatoes in and they're taking off really well. I've not used the deep planting method in previous years and I have a new drip line automated watering system in place, so I can't attribute the awesome growth this year *only* to the Rock Phosphate...but it makes sense that with additional soil contact (more stem buried for new root growth), consistent watering, and plenty of phosphorus available to the tomato plants, these tomatoes are going to thrive even in the heat this summer. ## Frequently Bought Together - Espoma RP28 Rock Phosphate – 28lb Organic Plant Fertilizer! for Outdoor Flower Or Vegetable Gardens – Promotes Blooming & Root Growth – for Use On All Plants - Espoma Organic Bone Meal Fertilizer 4-12-0.
