Standard red robin - poorly!!!
I have a standard red Robin at the front of my house. It out out very little grown last year and the leaves look marbled with speckles and I was to give it a boost. Any ideas. I have had this in a pot for 5 years, I then planted into the ground about a year and a half ago, I loosened the roots and put plenty of compost in the hole when planting as its clay! I also dug sand,grit and compost into the bed to improve the heavy heavy clay. How can I give it a boost and pick it up. In the bed under this tree I planted bedding plants last year. This standard red robin is now about 4ft tall but the round head is probably only a sphere about 2ft across.
