It is a good idea to prevent your rosemary from flowering, as this increases growth and improves flavour in the leaves.
How to prevent rosemary from flowering
To prevent rosemary from flowering, regularly pinch off the flower buds as soon as you see them. This redirects the plant's energy into leaf production, keeping the rosemary tasting better. Also, ensure it gets enough sunlight and isn't stressed by under or overwatering, which can trigger flowering.
Should you want your rosemary to flower - how to encourage flowering
Native to the Mediterranean, rosemary thrives in nutrient poor, and sandy soils. If you’ve used a nitrogen rich fertiliser, it will promote the growth of foliage at the expense of flowers.
To encourage your rosemary to flower, do not use fertiliser. Rosemary is a plant that thrives on neglect, especially if the goal is flowering. Amend your soil with sand, grit, or perlite to improve the drainage of your soil.
