OK Lannerman, will give some more of the Miracle Grow but should I wait a week or so after putting in the bone meal? I am worried that I may overdo it!

I think the plant must be three to four feet above compost level and that is to the tip of the plant. The pot is big enough for now but I am thinking towards repotting it in the autumn. I can email a photo to you or others if it will help.
