Great product, came quickly and is a good layer in winter time.
Great for the garden. Like that they are all natural
Great idea and so good for the garden.
Everything grows amazingly well 💯
I popped these wool pellets into the soil around my roses and they are flourishing. At this time of year I have the same amount of foliage and blooms as I did early spring. I am very pleased with how they look. (I did have to go back and push the pellets into the soil!)
