Picea abies 'Cohasset'

I like this one.
Question for you - we will be moving house within the next 18 months and will be going to a house with a small courtyard garden. The plan is to put a large raised decked patio in once an old building is remodelled. Are any of these suitable for container planting or do they all get too big? Bear in mind they have to withstand heat in the summer, cold and high winds in the winter.
No hurry on this one but you have really inspired me

Hi Maple, no real easy answer, first off it is difficult to keep any evergreen looking good and healthy especially conifers over the long term in containers. Whilst not so much of a problem in its youth, say the first 3-4 years, even then you will need to attend to its watering requirements, feeding and potting on as the root system develops, depending on the size of the container you start with. Please bear in mind once conifers become anywhere close to being rootbound they will start to suffer and look poorly. For example the plant in the picture is around 10 years old measures approx 60 cms x 45 cms, grows around 5-6 cms per year, you would need a container around 75 litres capacity to accomodate this plant anywhere near to a healthy condition.

Thanks for the answer Blue. I won't say the words I thought when I read it since I'm being polite!!
Had a rethink after though and decided to dig over part of the courtyard and utilise that as a conifer bed. Nearer the time I'll come back to you for advice. Thanks again
