Mountain rue, also known as Mountain rue

Highly valued for its aromatic leaves, mountain rue is a sturdy evergreen shrub. Proper pruning maintains shape and health, involving selective thinning of older stems and removal of dead or diseased wood. The optimal pruning time is late winter before new spring growth starts. Pruning during this dormant period minimizes sap loss and promotes vigorous springtime growth. Regular pruning also enhances air circulation, reducing the risk of fungal infections and encouraging a compact, bushy form.

What Are the Benefits of Pruning Mountain Rue?

Pruning mountain rue encourages vigorous growth and helps maintain its shape, ensuring it fits within the designated space and remains aesthetically pleasing.

What Is the Best Time for Pruning Mountain Rue?

This timing prepares mountain rue for vigorous spring growth, allows for clear visibility of the structure for more precise cuts, and prevents disease entry. It also ensures mountain rue retains energy for the upcoming growing season and does not interfere with the flowering cycle, since mountain rue blooms on new wood.
