I bought a small bag. I scattered sparingly.
Soil fertility and carbon

I like coffee grounds too.

I just recently spread a "charged" mix of bio char on several roses. It is too early to tell but I will once I see results.

I have Tamora, Molineaux, and Sweet Chariot in pots. T & M are new and I re-potted SC. To those three I added enough charged char to equal at least 3% of the mix. (See link for further info about "charging" char.)

The remainder of my slurry was placed around the bases of these roses:

Mrs B R Cant on Fort and in the ground for two years. This rose is SO much better for me on fort. Many more blooms. Hope to see if it makes a great rose better.

Cl Devoniensis on fort. Planted about four years ago and it just sits there! I started pinching off the few buds in the hope of encouraging growth. The fort stalk below the graft is less than 1/2 inch in diameter.

Rev d'Or, own root and planted 4 ft from the base of a large long leaf pine. An amazing plant for me. Only in the ground for two years, it has about the best foliage in my garden. Huge, vigorous growth that I hope to assist in those bad conditions. Also, awaiting more frequent blooms.

Nile Cochet. Poor Niley. I am trying to save him. He was a mature own root that I planted in Florida soil less than two years ago with very little amendments. He has died back to a sickly one cane. My favorite Cochet, so far.

Brightside Cream is too close to the base of a large oak, Planted as a band last fall, she is making steady but slow growth.

Jaune Desprez is on the other side of Rev d'Or's pine tree. I am besotted with this scent and hope for rapid growth soon. About a year in the ground and very few blooms.
