Winchester Gardens NPK 6-3-9 Select Organics Potato Granular Fertilizer, 3-Pound

Worked well in new plot. Mixed in old manure and added NPK 6-3-9. Growing super. Picture a double row of large, healthy plants.

I used this on my potatoes in grow bags and they grew massive!

So far so good

My potatoes are growing very well

Works great for potatoes
