They require full sun to thrive, so choose a bright, sunny location for optimal growth.

3. Rosemary
Rosemary is an excellent deterrent for cats, as not only do they loathe the strong piney scent, but the sharp, intense herbal aroma keeps them away.

regularly will encourage bushy, compact growth and keep the plant from becoming leggy.
4. Curry Plant
'The curry plant emits a strong, spicy scent that cats find unbearable,' says Caleb Young. 'Its aroma closely resembles curry powder, which is particularly intense for their sensitive noses. That powerful fragrance is more than enough to keep them at bay, no matter where you place it.' Also, the curry plant has a coarse texture that cats tend to dislike.
Curry plants thrive in full sun, so be sure to place them in a bright, sunny spot – whether in a raised bed or a well-lit garden corner. Since the curry herb plant releases a strong odor when brushed against, consider planting it near entry points – such as holes in your fence or near gateways to your yard – or areas to discourage cats from venturing.
However, be cautious with this plant. Since it’s technically considered a weed it should be planted sparingly in your garden to prevent it from spreading uncontrollably.
The curry plant is relatively low-maintenance once established. Water it sparingly, allowing the soil to dry out between waterings. 'Once settled in, it's drought-tolerant and doesn’t require much care, making it an easy plant to maintain while keeping your garden cat-free,' explains Caleb Young.
5. Lemon trees
Cats aren’t fans of citrus, and lemon trees are full of oils like limonene and citral that they find unpleasant. The intense lemon scent is enough to make them keep their distance, discouraging cats from jumping down or climbing up to areas where they’re not welcome.
, lemon trees need plenty of sunlight, so where they can receive direct sun for at least 8 hours a day.
Consider planting the lemon tree in a raised bed or a larger pot. This allows it to be higher than other plants, making it an excellent guard for elevated areas that cats might use to get into your garden, such as fences or raised platforms.
to promote healthy growth and fruit production, which in turn enhances the strong scent that cats find repellent.
Lemon trees also enjoy a bit of humidity, so occasionally misting it using a spray bottle with water can help, especially in dry conditions.
6. Rue
, has a very strong, spicy scent that cats can’t stand. Not only does this potent fragrance keep cats at a distance, but it also serves as a natural pest repellent.
Rue thrives in full sun, so make sure to place it in a spot where it can receive at least six hours of sunlight each day.
Tammy Sons suggests: 'This plant should be placed along edges or mixed into flower beds, where its scent can act as a boundary to keep cats away from your more vulnerable plants.' The bitterness of the plant also makes it an excellent choice for deterring cats from chewing on it, encouraging them to stay away from the area altogether.
However, be mindful that rue is toxic if ingested, so it’s crucial to avoid planting it in spaces where pets or young children may come into contact with it.
Rue is fairly low-maintenance but does have some specific needs. Avoid overwatering. Rue prefers to dry out between waterings. Rue also prefers well-draining soil, and it’s a good idea to plant it in a spot that ensures excess water can escape easily.
Remember to regularly check the plant for pests, as its strong scent may also attract unwanted insects.
7. Lemongrass
Just as cats hate lemon trees because of their citrusy scent, they will also be deterred by lemongrass.
Plant your lemongrass in a sunny spot where it can receive at least six hours of direct sunlight each day to ensure healthy growth.
strategically, such as along garden borders or near entry points, its strong scent can create an effective barrier, keeping cats at bay and protecting more delicate plants and vulnerable spots in your garden, making it a useful and fragrant companion plant.
Gardening expert Nikki Bruner says: 'Lemongrass thrives in full sun and well-draining soil. Since it is native to tropical regions, it prefers warm temperatures and consistent moisture, but be sure not to overwater it.' It’s important to keep the soil consistently moist, especially during the hotter months, but avoid letting it become waterlogged.
'Regular pruning can help promote new growth and keep the plant healthy,' adds Nikki. This will also help maintain its compact shape and prevent it from becoming too unruly.
