Here's a breakdown of when not to prune:
* Winter: Pruning in winter can expose the plant to harsh conditions and leave it vulnerable to disease.
* Early spring: Pruning before flowering removes the flower buds, resulting in no blooms for that season.
* Late summer or fall: Pruning too late in the season can stimulate new growth that won't have time to harden off before winter, making it more susceptible to damage.
Note: You can prune off dead or damaged branches at any time of year, but avoid major pruning during the dormant season.
