Chorisia Speciosa Thorns - Knowledgebase Question

Question by lrsjf

Does it harm the chorisia speciosa tree to remove the thorns from the main trunk? I've seen bigger, older trees that don't seem to have any thorns on the trunk but don't know if they were manually removed or a natural occurrance with an older tree. What would be the best way to remove them if it won't harm the tree?

Horticulturally speaking, the pointy projections on the trunks of Chorisia are spines. Since spines are really modified leaves, it's possible they would fall off naturally as they age. You can expect that the spines are firmly attached, and breaking them off might injure the trunk, providing an entrance for insects or disease pathogens. If you're willing to take that chance, you can probably remove them one at a time with pliers.
