Q.Can You Safely Grow a Cheal’s Weeping Cherry Tree (Prunus \’Kiku-Shidare-Zakura\) in a Container
Dear Sirs, Can you help me please. I am thinking of growing a Cheal’s Weeping Cherry (Prunus ‘Kiku-shidare-zakura) in a container in my garden. Are these suitable for growing in a container and what size container would you recommend. I have been looking are various types of potting soil and I have been looking at one that is 50% peat free and 8 months slow release feed and water retention material with the soil. Is this suitable or do you need to use a special type of soil. Look forward to hearing from you. Colin Hurdsfield

Yes, you can grow this Cherry Tree in a container.
