Potted laurels not growing

[Bigmama1974]

Hi all, I have 6 potted cherry laurels in 70l pots and they just don't seem to be growing pass 5 feet. They are extremely healthly looking, green and bushy. They are in sunlight for the majority of the day, watered regularly. I've tried tomato plant liquid and soluble miricle grow but still no extra height. Please help. Thank you

RHS reckons they can grow to 4-8m in height, but can take 20 years to max. I would have suspected the limit of the pots but 70L is quite a size. We have a few different types of laurel and I just checked and they currently have a lot of new growth (just cut them back last month), so perhaps it's just time and weather?

Use the Miracle-Gro once a week and you should see a difference soon.
