That limits the amount of pruning I have to do. Hawaii Hibiscus is a large shrub that will grow to 5-8’ tall by 4-7’ wide. With ample space, you should only have to do limited pruning in the spring to clean up some branches. If it is an older shrub that needs to be rejuvenated, you can cut it back about 2/3 in the spring. The established roots will then shoot up new branches.
