How To Prune A Sage Bush: An Easy Step-By-Step Guide

As a herbaceous plant native to the Mediterranean region, sage is widely recognized for its aromatic leaves and various health benefits. However, pruning sage bush is crucial to maintain its health and beauty. Pruning helps in promoting new growth, enhancing the flavor of the leaves, and preventing fungus or pest infestations.

In this post, we’ll provide you with step-by-step guidelines on how to prune a sage bush effectively.

1. Timing

The best time to prune your sage bush is in early spring before new growth emerges. This timing ensures that you won’t cut off any fresh greenery while also allowing plenty of time for new shoots to grow by summer.

2. Tools

To properly prune your sage bush, you’ll need some essential tools like sharp garden shears or secateurs that can cleanly cut through woody stems without crushing them unnecessarily.

3. Identify Dead Wood

Dead wood typically takes on a brownish-gray color that distinguishes it from living tissue on the plant; therefore identifying deadwood shouldn’t be challenging if observed correctly. Trim out these sections as they serve no functional purpose and only attract pests or fungi while detracting from the overall appearance of your sage bushes.

4.Cut Back Old Growth.

Older branches will soon become woody instead of leafy; hence cutting back older branches will make way for younger healthier ones which are more efficient in photosynthesis than their older counterparts assisting in overall re-growth patterns within Sage plants helping them stay healthy long-term.

(a) Removing one-third rule:

When doing this type of pruning never remove over a third at any one go/sitting.

As an example if there is 30cm (12inch) branch then roughly 10 cm (4 inches) would be removed per year so as not to stress the plant.

(b)Cutting above New Growth:

While cutting back old growth branches, make sure to cut just above a healthy new shoot. Doing so will encourage more vigorous and well-structured growth from that point because of the plant’s natural hormone response.

5. Shape it up

Once you have removed all deadwood and trimmed back any older branches, shaping the shrub is relatively simple. Use your shears or secateurs to trim off any excess length on newer shoots that are starting to grow too long, ensuring smooth cuts at an angle of around 45 degrees for optimal wound healing with minimal sprout-up.


Pruning your Sage Bush does not need to be difficult if done correctly; these steps provide guidelines necessary for maintaining healthy sage plants in gardens or greenhouses while also showcasing their beauty when grown properly over time. By following these easy-to-follow steps mentioned above, you can successfully prune your sage bush like a professional gardener!
