What You'll Learn
Catnip can be grown indoors or outdoors
Catnip, also known as catmint, is an herb that can be grown indoors or outdoors. It is native to Europe, Africa, and Southwest Central Asia, but it has been naturalised in North America. Catnip is easy to grow, and its growth habits are similar to those of mint. It will spread quickly and require regular trimming to keep it in check. Catnip is a great insect and rodent repellent, and it can also be used in cooking or made into a medicinal herbal tea.
When growing catnip, it is important to consider the climate zone and local conditions. In subtropical and tropical regions of Australia, catnip seeds should be sown during spring, summer, or autumn. In temperate, cold, or mountainous regions, seeds should be sown during spring or summer, after the risk of frost has passed. Catnip thrives in partial shade but needs at least six hours of direct sunlight per day. It grows best in moist, well-drained soil that is rich in organic matter. If your soil is sandy or heavy with clay, you can improve it by adding a layer of compost or well-rotted manure before planting.
Catnip seeds are small and should be covered lightly with a fine sprinkling of growing media. They can be started in small trays and then transplanted into individual punnet cells once they are big enough to handle. When planting catnip seedlings, space them about 40 cm apart to allow for growth. Young seedlings should be watered regularly. Catnip seeds can take 7 to 20 days to germinate, and the plants can take 4 to 5 months to mature and begin flowering.
Whether you choose to grow catnip indoors or outdoors, ensure that it receives plenty of sunlight and water. If growing indoors, use artificial grow lights if natural light is insufficient. Use a pot with good drainage and water regularly without flooding the soil. If growing outdoors, plant catnip in a sunny location and water regularly, especially during dry spells.

It's easy to grow, but thrives in partial shade
Catnip is easy to grow and will thrive in partial shade. It is a herb that can be grown indoors or outdoors, and it provides a range of benefits for cats. Knowing your climate zone is helpful when planning your garden, and there are many factors that may affect how your plants grow, including unseasonal weather conditions, the specific microclimate of your garden, and how you care for your plants. Catnip is drought-tolerant and, once established, only needs watering during prolonged dry spells. It is fairly tolerant of poor soils but grows best in free-draining soil rich in organic matter. If your soil is sandy, heavy with clay, or lacking in organic matter, you can improve it by adding a layer of compost or well-rotted manure before planting catnip.
The optimal time to plant catnip is in the spring, and it should receive plenty of water and sunshine to flourish. Catnip seeds are small and should be covered very lightly with a fine sprinkling of growing media. Press down gently to ensure good contact between the moist growing mix and the seeds, helping to prevent them from drying out between watering. Catnip seeds are best started in small trays and then transplanted to individual punnet cells once they are big enough to handle. When planting catnip seedlings, space them about 40 cm apart as they will trail and require room to grow. Water young catnip seedlings regularly.
Catnip seeds can have slow and erratic germination, taking 7 to 20 days to germinate after sowing. The expected germination time is approximately 10-20 days when sown at a soil temperature of 21-27°C. The temperature listed above is the ideal soil temperature for germination, and it's important to note that soil temperature usually differs from air temperature. Germination may occur outside of this window with decreased rates, or seeds may lie dormant in the soil until the ideal temperature is met. Catnip plants take 4 to 5 months to grow large enough to mature and begin flowering.
In subtropical and tropical regions of Australia, sow catnip seeds during spring, summer, or autumn. In temperate, cold, or mountainous regions, sow catnip seeds during spring or summer, ensuring any chance of frost has passed. Catnip is a convenient herb to grow at home, as it generally does well inside or out. If growing it indoors, ensure it gets plenty of sunlight or use an artificial grow light. Use a pot with good drainage so you can water it regularly without flooding the soil. If growing catnip outdoors, plant it in a sunny location and water it regularly unless you get lots of rain.

Catnip seeds should be covered lightly
Catnip is easy to grow and will grow quickly in most gardens. However, it can become a problem as it will spread like mint and will need to be trimmed regularly. Catnip is a member of the mint family and grows to a height of 3 to 4 feet. It has light green, feather-like foliage and small clusters of lavender flowers that grow on spikes. It is a herbaceous perennial that thrives in much of North America and some parts of Australia. It is native to Europe, Africa, and Southwest Central Asia and has been naturalized in North America.
Catnip seeds should be covered very lightly with a fine sprinkling of growing media. Press down gently to ensure good contact between the moist growing mix and the seeds. This will help prevent the seeds from drying out between watering. Catnip seeds are best started in small trays and then pricked out into individual punnet cells as soon as they are big enough to handle. When planting catnip seedlings into the garden, space them about 40 cm apart as they will trail and require lots of room to grow.
Catnip seeds can have slow and erratic germination, taking 7 to 20 days to germinate after sowing. For optimal germination, stratification is recommended for catnip seeds. This involves placing the seeds in a freezer overnight and then soaking them in water for 24 hours before sowing. After the stratification process is complete, sow the seeds in seed-starting trays about 1/8 to 1/4 inch deep. Keep the soil warm and moist, and the seeds should germinate in 5 to 10 days.
Catnip is drought-tolerant and, once established, should only need watering during prolonged dry spells. It is fairly tolerant of poor soils but will grow best in free-draining soil rich in organic matter. If your soil is sandy, heavy with clay, or pale and lacking in organic matter, you can improve it by adding a layer of compost or well-rotted manure before planting catnip. Catnip doesn't usually require additional fertilizer, but if growth is slow or there are signs of nutrient deficiencies, you can apply an organic fertilizer.

It's drought-tolerant and frost hardy
Catnip is a hardy plant that can withstand hard frost. It is drought-tolerant and frost-hardy, making it a good choice for gardeners in Australia. While it prefers moist, well-drained, moderately enriched soil, catnip will grow well in dry, sandy soil as long as it is watered during hot periods. It is also fairly tolerant of poor soils, although it will grow best when planted in soil rich in organic matter.
Catnip is native to Eurasia and has been naturalized in North America. It is widely found in temperate regions worldwide and is suitable for growing in subtropical and tropical regions of Australia. In these regions, catnip seeds can be sown during spring, summer, or autumn. However, in temperate, cold, or mountainous regions of Australia, it is recommended to sow catnip seeds during spring or summer, after the last frost.
To prepare catnip for winter, it is advisable to trim the plant back, cutting the stems down to a few inches. This helps protect new growth from potential damage caused by cold weather. Additionally, it is recommended to avoid fertilizing catnip as winter approaches, as new growth encouraged by fertilization may be susceptible to damage from colder temperatures.
Catnip is a low-maintenance plant that requires minimal care. It is an herbaceous perennial that can grow to heights ranging from 30 cm to over a meter, depending on its environment. It is known for its square-shaped stems, green to grey-green foliage, and fragrant leaves with scalloped edges. Catnip is valued for its ability to attract cats, bees, butterflies, and other pollinators while repelling insects and rodents.

Catnip is a natural insect and rodent repellent
Catnip (Nepeta cataria) is a herb that is part of the mint family. It is a perennial plant that grows natively in Europe, Africa, and Southwest Central Asia and has been naturalized in North America. It is also grown in Australia, where it is available as seeds or seedlings.
Catnip is well known for its ability to attract cats, with around two-thirds of cats being affected by the plant. However, it is also an effective natural insect repellent. The compound nepetalactone, found in catnip essential oil, is a potent natural insect repellent. Studies have shown that concentrations of 2% nepetalactone or higher are effective at repelling over 70% of mosquitoes for between one and four hours after application. Catnip oil has also been shown to repel other arthropods such as ticks, bed bugs, dust mites, and stable flies.
In addition to its insect repellent properties, catnip is also said to repel rats and mice. However, there is limited scientific evidence to support this claim. Some people have reported that rats and mice ate the catnip plants instead of being repelled by them. Nonetheless, the scent of catnip leaves is known to repel aphids and squash bugs, making it useful for companion planting around susceptible plants.
To use catnip as an insect repellent, you can rub the leaves between your hands and then rub it on your exposed skin. Alternatively, oil can be extracted from the leaves through steam distillation and used as a mosquito repellent. Catnip can also be planted in gardens to help repel insects and rodents naturally. However, it is important to note that catnip can be invasive and may need to be trimmed regularly to keep it under control.
