Rosemary is a wonderful and versatile herb that works well in everything from bread to pasta and even as a garnish in cocktails. However, constantly buying sprigs from the supermarket can be pricey, and often these herb packets end up forgotten in the back of the fridge.

If you want to keep a constant supply of rosemary on hand, you don't need a huge garden. In fact, you don't even necessarily need soil - all you need is a glass of water. Anya Lautenbach, author of The Money Saving Gardener, posted a video on social media about how to ensure you have rosemary year round.

To ensure a steady supply, all you need to do is cut off the tip of a shoot of rosemary and strip it of its lower leaves.

Place the cutting in a glass of fresh water and place it in a sunny spot then wait. In a matter of weeks, the rosemary will begin to root in the water. Just make sure you switch the water out every couple of days to make sure it stays fresh.

In the comments, Anya also noted you can put your cuttings straight into soil and it should take root. She said: "Putting it in the soil directly is also fine."

Anya said that this tip will mean you "never have to buy herbs again".

She also recommended other herbs that can be propagated in the same way including thyme, mint, marjoram, oregano, sage, basil, tarragon and lemon verbena.

Comments on the post thanked Anya for the tip. One woman wrote: "Love you for sharing these beautiful tips and tricks Anya. Thanks so much from a garden lover in Belgium."

Another said: "I LOVE herbs, Anya! Especially Rosemary. Thank you for your generous tips as always."
