- Know What You’re Eating: You control what goes into your soil and water, meaning no unwanted pesticides or chemicals.
- Aromatic Ambiance: Many herbs, like mint, rosemary, and lavender, release wonderful scents that can freshen your living space.
- Therapeutic Hobby: The act of nurturing plants can be incredibly calming and rewarding. It’s a little slice of nature indoors.
- Space Saver: Perfect for apartment dwellers or those with limited outdoor space. Most herbs don’t need a lot of room.
Choosing Your Herbs: The Easy Stars of the Show
Not all herbs are created equal when it comes to indoor growing. Some are super resilient and perfect for beginners, while others might need a bit more attention. Let’s look at some of the best, easiest-to-grow options for your indoor garden:
The “Can’t Go Wrong” Herb Club:
- Basil: Loves warmth and sun. Perfect for pesto, caprese salads, and adding a sweet, fresh aroma. Needs consistent moisture.
- Mint: Very easy to grow and spreads quickly (keep it in its own pot!). Great for teas, desserts, and cocktails. Tolerates some shade.
- Parsley: Both curly and flat-leaf varieties do well. Adds a fresh, slightly peppery flavor to countless dishes. Tolerates a bit less light than basil.
- Chives: Mild onion flavor, excellent in eggs, potatoes, and as a garnish. Very forgiving and grows back quickly after trimming.
- Oregano: A staple for pizza and pasta sauces. Likes good drainage and can tolerate slightly drier conditions once established.
- Thyme: Small leaves with a robust, earthy flavor. Needs excellent drainage and doesn’t like to be overwatered.
- Rosemary: Beautiful, fragrant, and delicious with roasted meats and potatoes. Needs lots of sun and excellent drainage.
- Cilantro: A bit trickier as it bolts (goes to seed) in heat, but fresh cilantro is worth it for Mexican and Asian dishes. Prefers cooler temperatures.
Herbs That Might Need a Little Extra Love:
- Dill: Can grow tall and may need staking. Prefers cooler conditions and can be sensitive to transplanting.
- Sage: Likes good airflow and can be prone to powdery mildew if humidity is too high. Needs bright light and good drainage.
- Marjoram: Similar to oregano but has a more delicate flavor. Prefers consistent moisture and indirect light.
My advice? Start with 2-3 of the “Can’t Go Wrong” herbs. As you get comfortable, you can expand your collection!
Seeds vs. Starter Plants: Which is Best for You?
When you’re starting your indoor herb journey, you have two main paths: beginning from seed or buying young plants (starter plants). Both have their pros and cons.
| Method | Pros | Cons |
|---|---|---|
| Seeds |

For absolute beginners, I often recommend starting with a few healthy starter plants. It’s a fantastic way to get immediate gratification and boost your confidence. Once you’ve had success, venturing into seeds is a fun next step!
The Essential Supplies: Gathering Your Gardening Toolkit
You don’t need a fancy greenhouse or a huge budget to start planting herbs indoors. Here’s a simple list of what you’ll need. Think of it as your starter pack for an indoor herb garden:
- Pots or Containers: These are crucial!
- Drainage is Key: Whatever you choose, make sure it has drainage holes at the bottom. This is non-negotiable to prevent root rot. Ceramic, terracotta, plastic, or even repurposed containers can work, as long as they drain.
- Size Matters: For most herbs, pots that are 6-8 inches in diameter are a good starting point. As plants grow, they might need a bigger home.
- Saucers or Trays: To catch excess water and protect your surfaces.
- Potting Mix: Don’t use garden soil! Garden soil compacts too much in pots, hindering drainage and airflow.
- Look for a good quality, peat-based or coco coir-based potting mix designed for containers. These are lightweight and provide good aeration.
- You can also add perlite or vermiculite to your mix to further improve drainage.
- Seeds or Starter Plants: As we discussed, choose based on your preference and patience level.
- Watering Can with a Fine Spout or Spray Bottle: Allows for gentle watering directly at the soil level, avoiding damage to delicate leaves.
- Sunny Location: Your go-to spot for light! This could be a south-facing windowsill, a bright east or west-facing window, or under grow lights.
- Optional (but recommended!):
- Grow Lights: Especially if you don’t have a very sunny spot. LED grow lights are energy-efficient and come in various types.
- Fertilizer: A balanced, water-soluble liquid fertilizer for houseplants or herbs.
- Small Trowel and Pruning Shears: For repotting and harvesting.
- Labels: To remember which herb is which, especially when they’re small.
Step-by-Step Guide: Planting Your Indoor Herb Garden
Ready to get your hands a little dirty? Follow these easy steps to plant your chosen herbs, whether you’re using seeds or starter plants.
Method 1: Planting from Seeds
This method requires a bit more patience but is incredibly rewarding!
- Prepare Your Pots: Ensure your chosen pots have drainage holes. Place a small amount of potting mix in the bottom.
- Fill the Pots: Fill your pots with fresh potting mix, leaving about an inch of space at the top. Lightly moisten the soil with water.
- Sow the Seeds:
- Check your seed packet for specific depths. A general rule is to plant seeds at a depth about twice their own diameter.
- For tiny seeds like basil or thyme, you can often just sprinkle them on the surface and lightly press them in, or cover with a very thin layer of soil.
- For larger seeds like chives, plant them about 1/4 to 1/2 inch deep.
- Plant 2-3 seeds per pot. You can thin them out later if multiple seeds sprout.
- Water Gently: Use a spray bottle for initial watering to avoid dislodging tiny seeds. Keep the soil consistently moist but not soggy.
- Provide Warmth and Light: Place the pots in a warm location. Many seeds germinate best with consistent warmth. Once you see sprouts, they will need bright light immediately. If you don’t have a sunny window, this is where grow lights are invaluable from day one.
- Patience is a Virtue: Germination times vary. Basil might sprout in 5-10 days, while parsley can take 2-3 weeks.
- Thinning Seedlings: Once your seedlings are about an inch tall and have a couple of true leaves, choose the strongest one in each pot and gently snip the others at soil level with small scissors.
Method 2: Planting Starter Plants
This is the quickest way to get your herb garden going!
- Inspect Your Plants: Before planting, gently check the starter plants for any signs of pests or disease. Inspect the leaves and soil.
- Prepare Your Pots: Ensure pots have drainage holes and have saucers underneath.
- Add Potting Mix: Fill the pots about two-thirds full with your chosen potting mix. Lightly moisten the soil.
- Remove Plant from Nursery Pot: Gently squeeze the sides of the plastic nursery pot. If the plant is root-bound (roots are tightly circling the base), you can gently loosen the bottom roots with your fingers.
- Place Plant in New Pot: Position the herb plant in the center of the new pot. The top of its root ball should be about an inch below the rim of the new pot.
- Fill with Potting Mix: Add more potting mix around the root ball, filling in any gaps. Gently firm the soil around the base of the plant.
- Water Thoroughly: Water until you see water draining from the bottom of the pot. Discard any excess water from the saucer after about 30 minutes.
- Place in a Bright Spot: Position your newly potted herbs in their sunny location or under grow lights.
Light Requirements: The Sunniest Spots in Your Home
Herbs are sun-lovers! This is one of the most critical factors for success. Most herbs need at least 6 hours of direct sunlight per day. If your home feels a bit dim, don’t despair – grow lights are your new best friend!
- Natural Light:
- South-facing windows are usually the best, offering the most intense and longest-lasting light.
- East or west-facing windows are the next best options, providing several hours of direct sun per day.
- North-facing windows are generally not sufficient for most sun-loving herbs.
- Grow Lights:
- Why use them? If your windows don’t provide enough light, or if you live in a cloudy climate, grow lights are essential to prevent leggy, weak growth.
- Types: Full-spectrum LED grow lights are energy-efficient and effective. You can get clip-on lights for individual plants or larger fixtures for multiple pots.
- Placement: Position grow lights about 6-12 inches above your plants.
- Duration: Aim for 12-16 hours of light per day. A timer can be very helpful for consistency. Learn more about ensuring your plants get the right light spectrum from resources like the University of Minnesota Extension.
Watering and Feeding Your Herbs: Finding the Sweet Spot
Getting the watering right is key to happy, healthy herbs. It’s a balance – not too much, not too little!
Watering Wisely:
- The Finger Test: The best way to know when to water is to stick your finger about an inch into the soil. If it feels dry, it’s time to water. If it feels moist, wait a bit longer.
- Water Thoroughly: When you water, do it until water starts to come out of the drainage holes. This ensures the entire root ball gets moisture.
- Empty Saucers: Always empty the saucers after about 30 minutes. Letting plants sit in standing water is a fast track to root rot.
- Avoid Overwatering: This is the most common mistake! Symptoms include yellowing leaves and wilting (even when the soil is wet).
- Avoid Underwatering: Symptoms include wilting, dry, crispy leaves, and stunted growth.
- Consider Humidity: Indoor air can be dry, especially in winter. Some herbs, like basil and mint, appreciate a little extra humidity. You can group plants together or use a pebble tray filled with water (make sure the pot sits on the pebbles, not in the water).
Feeding Your Herbs:
Potting mix has nutrients, but they get used up over time. Herbs grown indoors, especially, benefit from occasional feeding.
- When to Feed: Start feeding about 4-6 weeks after planting, or when you notice growth slowing down.
- What to Use: Use a balanced liquid fertilizer (like a 10-10-10 or formulated for herbs/vegetables) diluted to half or quarter strength. A good organic option is organic compost teas or fish emulsion.
- How Often: Feed about once a month during the active growing season (spring and summer). You can reduce or stop feeding in the fall and winter when plant growth naturally slows.
- Don’t Over-Fertilize: Too much fertilizer can burn roots and negatively impact flavor.
Pruning and Harvesting: Keep Them Happy and Productive!
Regularly trimming your herbs is not just for harvesting; it’s crucial for encouraging bushier growth and preventing plants from becoming leggy and unproductive.
- When to Harvest: You can start harvesting small amounts once the plant is established and has plenty of leaves. For seedlings started from seed, wait until they are a few inches tall and have developed several sets of leaves.
- How to Harvest:
- Pinch or Snip: Use clean scissors or your fingernails to snip stems just above a set of leaves. This encourages the plant to branch out from that point.
- Don’t Take Too Much: Never remove more than one-third of the plant at any given time. This allows the plant to recover and continue growing.
- Harvest Regularly: The more you trim, the more the plant will grow! It’s a win-win.
- Pruning for Shape: If a plant starts to look leggy (long, thin stems with few leaves), prune it back more significantly to encourage new, compact growth.
- Deadheading: If any herbs start to flower (like basil), pinch off the flower stalks. For many herbs, flowers signal the end of leaf production, and the leaves can also turn bitter. If saving seeds is your goal, let a few go to flower.
Troubleshooting Common Indoor Herb Problems
Even with the best intentions, you might encounter a few hiccups. Here are common issues and how to fix them:
| Problem | Possible Cause(s) | Solution(s) |
|---|---|---|
| Yellowing Leaves | Overwatering; insufficient light; nutrient deficiency (less common initially). | Check soil moisture before watering; ensure adequate light (move to brighter spot or |
