‘Rosemary is woody Perennial shrub, so it’s perfectly normal to become woody as it ages,’ explains Christopher O’Donoghue, director. Revive the garden.

The key thing to understand? Rosemary will not regenerate from old, bare wood, so reviving it is less about cutting it back hard, and more about encouraging healthy growth that is already there.
With that in mind, then…
1. Start with careful, strategic pruning
Prune rosemary Woody rosemary is the most effective way to get it back in shape, but it does require a light touch.
‘The most important thing is to find where the green growth ends and the woody stem begins,’ says Christopher. ‘You want to cut just above that point, making sure to leave some green growth on each stem.
To do this, you will need:
Remember: cutting too far into old wood can do more harm than good, as those sections are unlikely to produce new shoots. Instead, focus on reshaping the plant and encouraging bushier growth from leafy areas.
Christopher also recommends following the one-thirds rule, which essentially states that you should never remove more than one-third of a plant at a time. If your rosemary is particularly overgrown, it’s better to cut it back gradually over a few months and cut it back all at once.

If your rosemary leaves are dropping or turning brown at the tips, the problem may be below the surface.
‘Rosemary naturally grows in dry, rocky conditions, so it doesn’t really like sitting in wet soil,’ explains Christopher.
If your plant is in a pot, gently remove it and examine the roots. Healthy roots should be firm and pale, while dark, sticky roots are a sign of rot and should be cut off.

This mimics the plant’s natural growth conditions and helps prevent further stress.

Great advice, but what does it really mean? Well, outside, you want a bright, open position. Indoors, a south-facing windowsill is ideal. The goal is to have at least six to eight hours of direct sunlight each day. At least.
What to do after rosemary pruning?
Once you cut your rosemary, a little care can make a big difference in its recovery.

With some careful pruning, good drainage and the right conditions, you can encourage fresh growth and get it back in shape. If not, take the cutting and start over, ready to be a little more careful with your secateurs going forward.
