Stripping leaves from black bamboo

Hi GerryWhen in Bloom this year I noticed a black bamboo in one of the show gardens. It had been stripped of leaves from the ground to about 4 ft up. It looked very attractive.I would like to do the same with my bamboo at home but wonder if it is advisable.My bamboo is about 8 ft high and planted in an area where its roots are restricted from spreading by a surround of roof slate embedded around it in the soil. It seems quite healthy so I adopt an attitude of laisser-faire. Thanks for your advice.
