Catnip Care: Planting, Growing, and Harvesting Catnip

Catnip Facts

Catnip, also known as Nepeta cataria, is a perennial herb that belongs to the mint family. It is native to Europe and parts of Asia but is now commonly found in North America as well. Catnip has a distinctive aroma that attracts cats, making it popular among pet owners who use it as a treat or a playtime incentive for their feline friends. However, catnip can also be used for human consumption in various forms such as tea or seasoning.

One interesting fact about catnip is its effect on cats. When cats come into contact with the plant’s leaves or stems, they typically exhibit behaviors like rolling, rubbing their faces against it, purring loudly, or becoming hyperactive. This response is due to the presence of nepetalactone in catnip’s essential oil, which triggers sensory neurons in cats’ noses and brains. Not all felines react the same way though. Approximately 50-75% of cats are affected by catnip. Others show little to no interest at all.

Apart from its appeal to our feline companions, humans have been using catnip for centuries for its medicinal properties. The herb has been traditionally employed as a natural remedy for various ailments including digestive issues, headaches, insomnia, and anxiety. Its relaxing properties make it an ideal ingredient for herbal teas aimed at inducing sleep or calming nerves. Additionally, some people apply crushed catnip leaves topically to soothe insect bites or relieve skin irritations due to its anti-inflammatory effects.

Planting

  • Catnip can be planted outdoors after the last frost in spring or early summer. Seeds can be started indoors 6-8 weeks before the last frost for a head start.
  • Catnip thrives in full sun, but it can also tolerate partial shade. Place catnip plants in a location that receives at least 6 hours of direct sunlight per day.
  • Catnip plants should be spaced about 18-24 inches apart to allow enough room for them to grow and spread out.
  • Avoid planting catnip near vegetables or herbs like tomatoes, as they may attract cats that could potentially damage nearby plants. If you have indoor cats, it’s best to avoid planting catnip inside your home or directly outside windows where they may become overly stimulated.
  • Catnip spreads rapidly so avoid planting it in areas where you don’t want it to take over, such as flower beds or other delicate plants. Consider planting catnip in containers or raised beds to contain its growth.

Growing

  • Once you have planted the catnip seeds, make sure to water them consistently. Seedlings require moist soil for healthy growth. A good way to check if they need watering is by touching the soil with your finger; if it feels dry about an inch down, it’s time to water them. However, be careful not to overwater as this can lead to root rot.
  • When transplanting your catnip seedlings into a larger pot or garden bed, remember to space them around 18 inches apart from each other. This will provide enough room for each plant to grow and thrive without competing for resources. Gently remove the seedling from its container or nursery tray and place it into a hole in the soil at the same depth as it was previously growing.
  • As your catnip seedlings continue to grow, ensure they receive adequate water regularly. Consistent moisture levels are essential during this stage of growth. It is recommended to water them deeply once or twice a week rather than shallowly every day.
  • If your catnip seedlings start overcrowding each other or appear weak and spindly, thinning may be necessary. Carefully remove any extra plants so that remaining ones have enough space and nutrients for optimal growth. Thinning also helps prevent diseases related to poor airflow among plants.
  • Unlike their delicate seedling stage, mature catnip plants require less frequent

Nepeta cataria
The first is Nepeta cataria, or common catnip. This variety is loved by cats for its potent aroma and minty flavor. Another popular choice is Nepeta faassenii, also known as catmint. This variety has beautiful lavender-blue flowers and a more mellow scent compared to common catnip.
Nepeta citriodora
If you’re looking for something a little different, try the lemon-scented variety of catnip called Nepeta citriodora. Its citrusy fragrance is thought to be especially appealing to felines. Or you could opt for the silver-white foliage of Nepeta racemosa ‘Walker’s Low’, which not only looks stunning in the garden but also entices cats with its strong aroma.

Harvesting

  • Harvest catnip when it is in full bloom, typically around mid to late summer. This is when its essential oils are at their peak and the plant is most potent.
  • Look for signs of maturity such as flowers fully opened and leaf color rich and vibrant. Catnip leaves should also be slightly fuzzy to the touch.
  • Use a pair of sharp gardening shears or scissors to cut off the stems just above a set of leaves. Be sure not to prune too much, as this can weaken the overall health of the plant.
  • Once harvested, tie small bunches of catnip stems together with string or rubber bands.
  • Hang these bundles upside down in a cool, dark, well-ventilated area like a basement or closet.
  • Let them air dry for about two weeks until they become brittle.

Interesting facts

Catnip, known scientifically as Nepeta cataria, is a plant that holds many mysteries and interesting facts. One of the most intriguing aspects of catnip is its taste. For humans, it has a minty and slightly bitter flavor that can be used in teas or added to recipes for a unique twist. But what about cats? Well, catnip tastes like bliss to our feline friends. It contains a chemical compound called nepetalactone which triggers a euphoric response in cats when they sniff or consume it. This reaction can range from playfulness and friskiness to pure relaxation and contentment.

Aside from its tantalizing taste for cats, there are hidden mysteries surrounding the history of catnip. Although native to Europe and Asia, this herbaceous perennial has spread all over North America due to its popularity with domesticated felines. However, little is known about how exactly catnip made its way across the ocean to become so prevalent in American gardens. Some historians believe that English colonists brought it with them as a familiar source of medicine for treating various ailments such as headaches or stomachaches.

Symbolically speaking, catnip has been associated with love and fertility throughout history. In ancient times, women would carry dried catnip in amulets or sachets to attract suitors or ensure marital bliss. Additionally, farmers would sometimes plant catnip near their homes to ward off evil spirits believed to bring bad luck or infertility upon their livestock. So whether you’re planting catnip

Pest and Diseases:

  • Aphids: These tiny insects are a common pest for catnip plants. They feed on the sap of the plant and can cause stunted growth and yellowing of leaves. Regularly inspect your catnip plants for aphid infestations and treat them with insecticidal soap or Neem oil if necessary.
  • Powdery Mildew: This fungal disease appears as a white powdery substance on the leaves of catnip plants. It thrives in humid conditions and can weaken the plant if left untreated. To prevent powdery mildew, make sure your catnip has good air circulation by spacing out the plants adequately. If you notice signs of infection, remove affected leaves and spray with a solution made from one part milk to nine parts water.
  • Spider Mites: These minuscule pests suck on the plant’s sap, causing yellow spots on leaves which eventually turn brown and fall off. Spider mites thrive in dry conditions, so ensuring that your catnip plants have sufficient moisture will help deter them. Introduce natural predators like ladybugs or lacewings into your garden to control spider mite populations naturally.
  • Rust: This fungal disease manifests as orange or brown spots on lower leaves of catnip plants. It spreads rapidly in wet conditions, so avoid overhead watering and ensure good drainage for your plants. Remove infected leaves promptly to prevent further spread but avoid composting them as rust spores can survive in compost piles.
