I saw something posted by John Peat on Facebook earlier this year in regards to slow plant growth. Assuming all other plants are performing, he suggested that you should dig up the plant and remove all the dead roots and replant. He suggested that the plants have a large mass off dead root material and in the ground that makes it very hard for the plants new roots to grow.
I had 2 that were very slow to grow and multiply. So I decided I had nothing to lose. I did this in August The varieties were Grand Old Flag & Wyoming Wildfire. I had 2 fans of GOF after doing a trade and WW had finally gotten up to 5 fans. I now have 3 fans of GOF & 6 cans of WW. I also applied lawn fertilizer when I replanted.
I also applied this to Hillbilly Heart which has performed very poorly here. It has not shown any increase but the fan did grow close to mature size. I will see what it does next year. If there is no improvement with this one it will leave.
