I had all sorts of difficulties keeping my garden healthy so I went to see the guys at Mirror and they put me onto Canna nutrients. They got me on the good stuff and were knowledgeable about what they were selling. I used Canna Boost Accelerator during flowering, and I am quite happy with the results.
The garden section is inside the paint shop so I am comfortable shopping there and would recommend it to anyone.

Approximate cost: $110
