Step-by-Step Guide: Growing Catnip from Seed Indoors
Catnip is a herb that is loved by cats all over the world. It is a member of the mint family and is known for its intoxicating effect on our feline friends. If you want to provide your cat with a fresh and endless supply of catnip, why not try growing it from seed indoors? Not only is it a fun and rewarding project, but it also ensures that your cat has access to high-quality, organic catnip whenever they desire.
Growing catnip from seed indoors is a relatively simple process that requires minimal effort and supplies. All you need is a sunny windowsill, some potting soil, and a packet of catnip seeds. By following a few easy steps, you can have a thriving catnip plant in no time.
First, start by filling a small pot or container with well-draining potting soil. Make sure the pot has drainage holes at the bottom to prevent waterlogging. Moisten the soil slightly before sowing the seeds.
Next, sprinkle the catnip seeds evenly over the soil surface. Lightly press them into the soil, but do not cover them completely, as catnip seeds require light to germinate. Mist the seeds with water to ensure they are in contact with the soil.
Place the pot in a sunny location, such as a south-facing windowsill, where the catnip will receive at least 6-8 hours of direct sunlight each day. Keep the soil consistently moist, but not waterlogged, by misting it regularly or using a spray bottle.
In about 7-10 days, you should start to see the catnip seeds sprouting. Once the seedlings have grown a few inches tall, you can thin them out, leaving the strongest ones to continue growing. Be sure to space them at least 12 inches apart to allow for proper air circulation.
As the catnip plants grow, you can encourage bushier growth by pinching off the top leaves. This will help the plant to branch out and become fuller. Additionally, remember to continue watering the plants regularly and providing them with enough sunlight.
After a few weeks, your catnip plants should be ready for harvesting. Simply snip off the leaves and stems, and let them dry in a cool, dark place. Once dried, you can store the catnip in an airtight container for future use.
Now that you know how to grow catnip from seed indoors, you can enjoy watching your cat indulge in their favorite herb all year round. Not only will your feline friend be grateful, but you will also have the satisfaction of knowing that you provided them with a safe and natural source of entertainment.
Choosing the Right Seeds
When it comes to growing catnip from seed indoors, choosing the right seeds is essential for a successful harvest. Here are some tips to help you select the best seeds for your indoor catnip garden:
1. Look for organic seeds: Organic seeds are free from synthetic chemicals and pesticides, making them a healthier choice for both you and your cats.

Preparing the Indoor Environment
Before you start growing catnip from seed indoors, it’s important to create the right environment for your plants to thrive. Here are some steps to prepare the indoor environment:
1. Choose the Right Location
Find a location in your home that receives plenty of sunlight, preferably a south-facing window. Catnip plants require at least 6 hours of direct sunlight each day to grow properly. If you don’t have a suitable window, consider using artificial grow lights to supplement the light.
2. Provide Adequate Temperature and Humidity
Catnip plants prefer temperatures between 65°F and 75°F (18°C and 24°C). Make sure the room where you plan to grow the plants stays within this temperature range. Additionally, catnip plants thrive in moderate humidity levels, around 40% to 60%. You can use a humidifier or place a tray filled with water near the plants to increase humidity.
3. Prepare the Soil
Use a well-draining potting mix to ensure proper drainage for your catnip plants. You can either purchase a commercial potting mix designed for herbs or make your own by combining equal parts of peat moss, perlite, and vermiculite. Fill your pots or containers with the soil mixture, leaving about an inch of space at the top for watering.
4. Choose the Right Containers
When growing catnip indoors, it’s best to use containers with drainage holes to prevent waterlogging. Plastic or clay pots work well for catnip plants. Make sure the containers are large enough to accommodate the root system and allow for growth. A 6-inch (15 cm) diameter pot is usually sufficient for one catnip plant.
5. Clean and Disinfect
Before planting your catnip seeds, clean and disinfect your pots or containers to prevent the spread of diseases or pests. Wash them with warm, soapy water and rinse thoroughly. You can also use a diluted bleach solution (1 part bleach to 9 parts water) to sanitize the containers. Rinse them well after disinfecting.
By following these steps to prepare the indoor environment, you’ll create the ideal conditions for your catnip seeds to germinate and grow into healthy plants.
Starting Catnip Seeds
Starting catnip seeds indoors is a great way to ensure a successful growing season. Here are some steps to get you started:
1. Gather your supplies
Before you begin, make sure you have all the necessary supplies. You will need:
- Seed starting trays or pots
- Seed starting mix
- Catnip seeds
- A spray bottle
- Plastic wrap or a clear plastic dome
- A grow light or a sunny windowsill
2. Prepare the seed starting mix
Fill your seed starting trays or pots with a seed starting mix. This type of soil is light and airy, which is ideal for seed germination. Moisten the soil with water until it is evenly damp, but not soaking wet.
3. Sow the catnip seeds
Using your finger or a small tool, create small holes in the soil for the catnip seeds. Place one or two seeds in each hole, and then cover them lightly with soil. Press the soil down gently to ensure good seed-to-soil contact.
4. Provide moisture and warmth
Mist the soil surface with water from a spray bottle to keep it moist. Cover the trays or pots with plastic wrap or a clear plastic dome to create a mini greenhouse effect. This will help retain moisture and provide warmth for the seeds to germinate.
5. Place in a warm location
Find a warm location for your seed trays or pots. A temperature of around 70°F (21°C) is ideal for catnip seed germination. If you don’t have a warm spot in your home, you can use a seedling heat mat to provide the necessary warmth.
6. Provide light
Once the catnip seeds have germinated, remove the plastic wrap or dome and place the trays or pots under a grow light or on a sunny windowsill. Catnip requires at least 12-16 hours of light per day to grow properly.
Following these steps will help you successfully start catnip seeds indoors. Remember to keep the soil moist, provide warmth, and give the seedlings enough light to thrive. Soon, you’ll have healthy catnip plants ready to be enjoyed by your feline friends!
Providing Adequate Light
When growing catnip from seed indoors, it is important to provide adequate light for the plants. Catnip plants thrive in bright, direct sunlight, so it is essential to place them in a location that receives at least 6-8 hours of sunlight per day. If you don’t have access to natural sunlight, you can use artificial grow lights to provide the necessary light for the plants.
When using artificial grow lights, it is important to choose the right type of light. LED grow lights are a popular choice for indoor gardening because they are energy-efficient and provide the full spectrum of light that plants need for photosynthesis. Place the grow lights about 6-12 inches above the plants to ensure they receive enough light.
It is also important to provide a consistent light schedule for the catnip plants. Aim for 14-16 hours of light per day during the vegetative stage, and then reduce it to 12 hours of light per day during the flowering stage. This mimics the natural light cycle and helps the plants grow and flower properly.
Monitoring Light Intensity
While providing adequate light is important, it is also crucial to monitor the intensity of the light. If the light is too intense, it can cause the plants to become stressed and wilt. On the other hand, if the light is too weak, the plants may become leggy and weak.
One way to monitor light intensity is by using a light meter. This device measures the amount of light in a specific area and can help you determine if the plants are receiving enough light. Aim for a light intensity of around 5000-7000 lux for catnip plants.
Preventing Light Burn
Light burn can occur when the plants are exposed to too much light for an extended period. This can cause the leaves to turn yellow or brown and can even lead to plant death. To prevent light burn, make sure to gradually introduce the plants to direct sunlight or artificial grow lights.
If you notice any signs of light burn, such as yellowing leaves or leaf curling, move the plants further away from the light source or reduce the intensity of the light. It is better to provide slightly less light than to risk burning the plants.
By providing adequate light and monitoring its intensity, you can ensure that your catnip plants grow healthy and strong indoors.
Watering and Feeding Catnip Plants
Proper watering and feeding are essential for the healthy growth of catnip plants. Here are some tips to help you keep your catnip plants well-nourished:
Watering
Catnip plants require regular watering to thrive. It is important to keep the soil consistently moist but not waterlogged. Overwatering can lead to root rot and other issues, so it is important to find the right balance.
Check the moisture level of the soil by inserting your finger about an inch deep into the soil. If it feels dry, it’s time to water the plant. Water the plant thoroughly, allowing the water to soak into the soil. Avoid watering the leaves, as this can promote the growth of mold and mildew.
During the summer months or in hot weather, you may need to water your catnip plants more frequently. Be sure to adjust your watering schedule accordingly.
Feeding
While catnip plants do not require heavy feeding, providing them with some nutrients can help promote healthy growth. You can use a balanced, all-purpose fertilizer or a slow-release fertilizer specifically formulated for herbs.
Apply the fertilizer according to the package instructions, usually once every 4-6 weeks during the growing season. Be careful not to over-fertilize, as this can lead to excessive foliage growth at the expense of essential oils.
In addition to fertilizer, you can also amend the soil with organic matter, such as compost or well-rotted manure, before planting. This will help improve the soil structure and provide some nutrients to the plants.
Regularly monitoring the health of your catnip plants and adjusting the watering and feeding practices as needed will ensure that they thrive and provide your feline friends with plenty of enjoyment.
Transplanting Catnip Seedlings
Once your catnip seedlings have grown to a height of about 2-3 inches and have developed a few sets of true leaves, they are ready to be transplanted into larger containers or outdoor garden beds. Transplanting catnip seedlings is a simple process that can help ensure their continued growth and health.
Before transplanting, make sure to prepare your new containers or garden beds. Fill them with a well-draining potting mix that is rich in organic matter. Catnip prefers a slightly alkaline soil, so you may want to add some lime to the mix if your soil is acidic.
Gently remove the seedlings from their original containers, being careful not to damage the delicate roots. If the seedlings are growing in a tray or cell pack, you can gently push up from the bottom to loosen the root ball. If they are growing in individual pots, you can carefully slide them out by holding the base of the stem and tapping the pot upside down.
Once the seedlings are out of their containers, dig a hole in the new container or garden bed that is slightly larger than the root ball of the seedling. Place the seedling in the hole, making sure that the top of the root ball is level with the soil surface. Gently backfill the hole with soil, firming it around the seedling to eliminate any air pockets.
After transplanting, water the seedlings thoroughly to help settle the soil and provide them with moisture. Keep the soil consistently moist, but not waterlogged, as catnip prefers well-drained soil. Place the newly transplanted seedlings in a location that receives full sun for at least 6-8 hours a day.
Continue to care for your transplanted catnip seedlings by watering them regularly, providing them with adequate sunlight, and fertilizing them every 4-6 weeks with a balanced organic fertilizer. With proper care, your catnip seedlings should continue to grow and thrive, providing you and your feline friends with many enjoyable moments.

Managing Pests and Diseases
While catnip plants are generally hardy and resistant to many pests and diseases, it is still important to monitor and manage any potential issues to ensure the health and vitality of your plants.
One common pest that may affect catnip plants is aphids. These small, soft-bodied insects can suck the sap from the leaves and stems, causing damage and stunting growth. To control aphids, you can try spraying the plants with a mixture of water and mild dish soap, or use an insecticidal soap specifically designed for aphids.
Another potential pest is the spider mite. These tiny arachnids can infest the undersides of leaves and cause yellowing, stippling, and webbing. To manage spider mites, you can try spraying the plants with a mixture of water and neem oil or insecticidal soap.
Fungal diseases, such as powdery mildew, can also affect catnip plants. Powdery mildew appears as a white or gray powdery coating on the leaves and can inhibit growth. To prevent powdery mildew, make sure your plants have good air circulation and avoid overhead watering. If powdery mildew does occur, you can try spraying the plants with a mixture of water and baking soda, or use a fungicide labeled for powdery mildew.
Root rot can be a problem for catnip plants if they are overwatered or if the soil does not drain well. To prevent root rot, make sure your plants are in well-draining soil and water them only when the top inch of soil feels dry. If root rot does occur, you may need to repot the plants into fresh soil and adjust your watering practices.
Regularly inspecting your catnip plants for any signs of pests or diseases and taking prompt action can help ensure the health and productivity of your plants. By following these tips, you can enjoy a thriving indoor catnip garden.
Harvesting Catnip Leaves
Once your catnip plants have reached a height of about 12 inches, it’s time to start harvesting the leaves. Harvesting catnip leaves is a simple process that can be done throughout the growing season.
Step 1: Choose the Right Time
The best time to harvest catnip leaves is in the morning, after the dew has dried but before the heat of the day sets in. This is when the essential oils in the leaves are at their highest concentration, giving the catnip its potent scent.
Step 2: Use Clean, Sharp Scissors
Before you begin harvesting, make sure your scissors are clean and sharp. This will help prevent the spread of diseases and ensure a clean cut, which promotes healthy regrowth.
Step 3: Cut the Stems
To harvest the catnip leaves, cut the stems about 1 inch above the soil level. This will encourage new growth and ensure that the plant remains healthy and productive.
Alternatively, you can also pinch off individual leaves if you only need a small amount for immediate use.
It’s important to note that catnip leaves are most potent when they are fresh, so it’s best to use them as soon as possible after harvesting. However, you can also dry the leaves for later use by hanging them upside down in a cool, dry place.
By following these simple steps, you can harvest catnip leaves and enjoy the benefits of this beloved herb for your feline friends.
Preserving Catnip
Once you have successfully grown catnip indoors, you may want to preserve it for future use. Preserving catnip allows you to have a fresh supply of this herb year-round. Here are a few methods you can use to preserve catnip:
Drying Catnip
One of the easiest ways to preserve catnip is by drying it. To dry catnip, harvest the leaves and stems when the plant is at its peak. Bundle the stems together and hang them upside down in a cool, dry place. Make sure the area is well-ventilated to prevent mold growth. Once the catnip is completely dry, remove the leaves from the stems and store them in an airtight container.
