How To Save a Dying Rosemary Plant

How to Save a Dying Rosemary Plant

Here are some of the steps you can take to save your dying rosemary plant and bring it back to life:

1. Rosemary with root rot

Common symptoms of rosemary with root rot often appear to look wilted or drooping with leaves that turn brown, yellow, or black.

The likely cause of root rot of rosemary could be over-irrigating, excess rainfall, poorly draining soil, and or high humidity.


Cut off parts with root rot; replant the rosemary in a new pot (repotting of rosemary), expose to full sun, unlike the Japanese maple tree which does not need excess sunlight.

You can also take cuttings of the dying rosemary for propagation as one of the ways to achieve a reasonably high success rate on how to propagate rosemary plants.

2. Rosemary with stunted growth

If you notice your rosemary is not growing well as expected, then it’s probably suffering from stunted growth. Some of the likely causes could be that it is not in full sunlight or it has been pot-bound.

This is what happens when rosemary is potbound; even though the rosemary plant is known to thrive significantly in poor soils and is rarely affected by insufficient nutrients, it can become root bound if it exhausts the potting soil and its nutrients if left for long in the same pot.


  • Repot rosemary in a new pot larger than the existing one (about 17inches across). Ensure it is 20% sand and 80% compost
  • In the case of a smaller pot where it is deprived of nutrients, application of a weak fertilizer in the spring can help
  • Prune for leaves for culinary purposes during spring or summer and to early Fall

Note: Please ensure you do not over prune the rosemary down to the woody base because older stems do not grow new foliages.

3. Yellow leaves and scanty flowers

Why is my rosemary turning yellow? One of the causes of rosemary turning yellow and scanty flowers is due to excess nitrogen as a result of rich soils.

Or it can also be too much fertilizer. Once this happens, it would be noticeable on the leaves and bloom.

Excess nitrogen can burn the roots thereby turning the leaves yellow which can lead to a reduction in the aroma and its culinary value.

Excess nitrogen will only stimulate foliage growth but without much taste and this would be at the disadvantage of the flowers


  • Reduce frequent application of fertilizer if you are consistently doing so
  • Aerate the soil around roots using a fork if the rosemary is in the ground and is already established. Doing so will help distribute sand around its base to will improve the soil structure.
  • It is good to amend the soil with a sandy soil mix of 20% and 80% compost. This formulation is best on how to repot a rosemary plant.

Here are some of the basic things you need for reviving a rosemary plant:

  • Light
  • Water
  • Fertilizer (compost)
  • Soil
  • Temperature and Humidity
  • Garden fork
  • Pot
