A shi shi is a type of sasanqua that is commonly known as a camellia. These shrubs will bloom in late fall to early winter. You DO NOT want to trim shi shis now because they are producing small buds for the fall. If you trim them, you would be cutting off the blooms and affecting the blooming cycle for the late fall months. If you absolutely need to trim a shi shi, be sure to make selective cuts and not an aggressive trim. Try to avoid cutting the small buds! The best time to trim is late winter, depending on the shrub’s blooming cycle. We hope this helps, and be sure to check out our knowledge base for more tips: matthewslandscape.com/search
