How can I effectively trim a bleeding heart bush to prevent bleeding and promote healthy growth?

To effectively trim a bleeding heart bush, use sharp, clean pruning shears to make clean cuts at a 45-degree angle just above a leaf node. Trim back any dead or damaged branches, and remove any crossing or crowded branches to improve air circulation. Avoid over-pruning, as this can cause excessive bleeding. Trim in early spring before new growth appears to promote healthy growth.
