Cats can become a little bit of a problem in gardens as they use your beds and borders as there own personal toilet as any gardener will no.
The problem with cats is that they will dig up seedling as well as young plants and dig holes in your beds and lawn. Of course, there is also the unfortunate times when you get it on your hands while gardening which is a health risk especially if you have children helping out on the garden.

Cat repellent plants
Cat repellent plants do not harm or scare cats they only deter them from the area
There are a few known plants that are shown to help deter cats in the same way some cats are attracted to certain plants. All though some plants do deter cats, it only works with around 70% of cats as with most types of cat repellents.
The scent of these plants is sensitive to cats and is sometimes enough to stop cats stopping and pooping around them, please note it will not keep cats out of your whole garden and they will probably walk by and pass through.
Scaredy cat plant (coleus canina)
The scaredy cat plant is one of the most popular cat repellent plants available. The odour it emits has a strong pee like the smell so it can be unpleasant to humans too all though some people have commented on how nice the smell is. Best planted directly in small problem areas or in a line to act as a barrier.
These plants grow well without much care and will grow in dry conditions. As cats tend to stay away from damp soil these plants can be just the plant to plant in that dry spot where they usually go to the toilet.
Lavender is a type of herb plant that is popular with gardeners both in the UK and USA and grows into a small shrub around 30cm (1ft) tall. It has a pleasant strong sweet smell but fortunately, most cats find it unpleasant so it can be effective in deterring the local cats.
Lavender grows well in poor and moderate soils and is drought tolerant so is ideal in dry areas of the garden. Ideal for planting in rows to act as a barrier or as single plants between plants and shrubs. Being evergreen unlike the scaredy cat plant is acts as an all year round cat repellent.
Lavender also grows well in pots so can be moved around to where the cats are pooping.
Curry Plant – Helichrysum angustifolium or Iitalicum
The curry plant is often sold as a shrub and produces yellow flowers and grows wild in Mediterranean areas. As the name suggests it smells like curry which cats are known to dislike the smell of making it the perfect cat deterrent plant. It does not have any culinary uses and is not a herb. It grows between 30-50cm and has a similar spread but can be pruned back in spring, it also grows well in poor dry soils.
Rosemary – Rosmarinus officinalis
Rosemary is usually grown for its culinary uses as it is a very popular garden herb with a very nice sweet scent that is very pleasant. Cats, however, are sensitive to the smell and do not like being around it so it makes for a good natural repellent with the extra benefit of being able to use it in cooking recipes.
Rosemary can be grown in pots as well as in beds and borders and prefers a dry site to thrive and will grow in poor soil. Rosemary is an evergreen plant making it an ideal choice as it does not need replacing every season like some plants. If your soil is damp wet soil then you would probably not succeed with this plant.
Rue – Ruta Graveolens
Rue is a shrub that has proven to deter cats and grows in dry soils, Rue is poisonous when eaten so care should be taken when using this plant. It not very popular as a plant but has shown good cat repellent capabilities.
Pennyroyal is one of the smallest varieties of the mint family and was once used in cooking. Nowadays it becomes known as an effective plant to deter cats. Its also known as pudding grass.
The plants above are all effective at deterring cats and as such are good cat repellent plants. Scaredy cat plant, Lavender, curry plant and Lavender have proved the most popular but there are many other plants that may be effective. It is hard to say which will work best as some plants thrive better in different areas and the size of the area you’re trying to deter them from. All the above plants deter cats because of there smell and planting them in rows often works well as a physical barrier.
Some other plants and shrubs that are worth mentioning are those with sharp thorns as they can be used to form a physical barrier and can be used to block areas where cats are known to travel through into your garden.
Prickly bushes ideal for deterring cats by forming a physical barrier
Hawthorn is a deciduous shrub with sharp thorns that if left not pruned would grow into a very large bush. Ideal for forming hedging and filling in gaps in hedges which cats may be walking through.
Wild Rose (Rosa rugosa) has lots of sharp thorns and can also be used to form a hedge, it produces nice flowers.
Bramble (blackberry) have very sharp thorns which cats will not walk through, the other advantage is you get to pick the blackberry fruits off in summer. There are thornless varieties of Blackberry so if deterring cats its best to ensure you don’t buy one of these varieties by mistake.
Pyracantha is an evergreen shrub with long sharp thorns which can be planted as a shrub or as a hedge. It others all year round colour and berries in late autumn. A beautiful shrub which our own website is named after.
Berberis is another shrub with many types available which include both evergreen and deciduous varieties. Ideal for planting to deter cats in areas where cats are passing through into your garden. If you have a small area where cats are pooping you can also plant Berberis which will keep them from doing so.
One of my favourite Berberis plants is a variety called Berberis thunbergii ‘Harlequin’, you can see a picture of it in Amazon.co.uk here.
