This guide will introduce you to ten of the easiest herbs to grow indoors, offering practical tips and advice to help you succeed. Forget farm to table; with an indoor herb garden, it's all about windowsill to table!
Selecting the Right Herbs: Easy Choices for Indoor Success
Choosing the right herbs is crucial for a successful indoor garden. Some herbs are naturally better suited to the indoor environment than others, thriving with less sunlight and adapting well to container growing. Here are some of the easiest and most rewarding herbs to cultivate indoors:
- Basil: A staple in Italian cooking, basil is easy to grow and adds a fresh, peppery flavor to pesto, pasta, and salads. Basil is often considered the easiest herb to grow, especially for beginners. It's adaptable, grows quickly, and is very forgiving if you forget to water it now and then.
- Mint: Known for its refreshing flavor and invigorating scent, mint is a versatile herb perfect for teas, cocktails, and desserts. Herbs in the mint family are especially easy to grow, even indoors [5]. An extra benefit of growing this herb indoors, rather than outdoors in the garden, is that it is invasive. Being contained in a pot on your windowsill, it has nowhere to go.
- Chives: With their mild onion flavor, chives are a delightful addition to soups, salads, and omelets. Chives are an excellent choice for those just starting their indoor herb garden. They're easy to grow and don't need much space, making them ideal for small apartments or limited areas [3].
- Parsley: A versatile herb with a fresh, clean taste, parsley is a staple in many cuisines and can be used as a garnish or ingredient in various dishes. Flat-leaf (Italian) parsley has a stronger flavor, while curly parsley is often used for garnish [7]. It's easy to grow indoors and adds freshness to a wide range of dishes.
- Oregano: A robust herb with an earthy flavor, oregano is essential for Mediterranean and Mexican cooking. Oregano is a must-have for anyone starting an indoor herb garden, especially if you love Greek or Italian cooking [3].
- Thyme: With its delicate, woodsy flavor, thyme is a versatile herb that complements meats, vegetables, and soups. Appealing to both ornamental and culinary green thumbs, thyme is an herb garden staple that thrives indoors [1].
- Rosemary: An aromatic herb with a distinctive piney scent, rosemary adds a unique flavor to roasted meats, vegetables, and bread. Rosemary is an aromatic herb that brings a fragrant touch to any indoor herb garden [3].
- Cilantro: Popular in Latin American and Asian cuisine, cilantro has a bright, citrusy flavor that enhances salsas, tacos, and stir-fries. Cilantro is a tasty herb that brightens up dishes with a fresh, citrusy flavor [5].
- Sage: Sage can be successfully grown indoors remembering that lavenders must dry out well between waterings [14].
- Lemon Balm: Part of the mint family, with a strong citrus smell to its leaves. Put the leaves in hot water to make a calming tea [6].
Setting Up Your Indoor Herb Garden: Essential Elements
Creating the right environment is key to a thriving indoor herb garden. Here's what you need to consider:
Light: The Sun's Energy
Most herbs need at least 6 hours of sunlight daily [3, 8]. A south-facing window is ideal, but if you don't have one, consider using grow lights to supplement natural light [2, 8]. Position your herb garden in a south or southwest-facing window that receives 6+ hours of direct sunlight daily [12]. The more intense the light source, the more flavoursome your herbs will be [10]!If your window isn't exposed to enough light during the day, you will need to provide lights for your plants using fluorescent lighting [9]. For an hour of natural light, you will have to provide two hours of artificial light [9].
You'll know your herbs are not getting enough light if they start getting leggy (tall and spindly) and/or the new leaves seem stunted compared to older ones [2].
Containers and Soil: Providing the Right Foundation
Choose pots with drainage holes to prevent waterlogging [2, 8]. Terra cotta pots are a good option as they allow the soil to breathe [2, 14]. Use a well-draining potting mix, not garden soil, which can become compacted indoors [20].
The planter, pot, or container that you select should be big enough to fit the root ball of the herb you'd like to grow [2]. The herbs I recommend growing indoors have shallow roots, which means your pot or container only needs to be 6 inches deep to contain them [2].
The growing media used is important for 3 very distinct reasons [21]:
- It acts as a reservoir for moisture and nutrients around the roots of the plants, allowing them access to the resources they need.
- It provides “empty” space around the roots for oxygen, allowing the roots to breathe.
- It provides upright support to plants by anchoring the roots.
Watering: Finding the Right Balance
Water when the top inch of soil feels dry to the touch [3, 17]. Avoid overwatering, which can lead to root rot [3, 17]. Consider watering your herbs from the bottom [2]. Place a saucer or flat-bottomed container underneath the herb pot and fill it with water [2]. Allow the top 1 to 2 inches of the soil to dry out before watering [2].
The key to watering herbs indoors is not to overdo them. Letting herbs dry out before rewatering can help ensure that you don't flood them with water [10]. Because herb roots are delicate, they are easy to over and underwater [10]. Test the soil by inserting a finger about 2 inches deep [10].
Temperature and Humidity: Creating a Comfortable Climate
Most herbs thrive in temperatures between 65-75°F (18-24°C). Indoor environments can sometimes be too dry for herbs, particularly in air-conditioned spaces [17]. A small fan can help keep the air moving around your plants [17].
Increase humidity around your plants by misting them regularly or using a humidity tray [17].
Caring for Your Indoor Herb Garden: Maintenance and Harvesting
Once your herb garden is set up, regular care will ensure healthy growth and abundant harvests:
Fertilizing: Providing Essential Nutrients
Indoor herbs benefit from occasional feeding. Use a balanced, water-soluble fertilizer every 4-6 weeks [17]. For edible indoor herbs, veggies, and smaller potted plants, natural plant fertilizers that include liquid humus, composted manures, seaweed, etc., are good choices [24]. It's tough to over-fertilize or burn your plants with low-nitrogen organic fertilizers, but still never apply more than is instructed on the label, especially when you're growing in an aquaponic or hydroponic system or in containers [24].
Pruning: Encouraging Growth
Regularly prune your herbs to encourage bushier growth and prevent them from becoming leggy [3]. Prune some mature and new leaves [8]. With those tips, you'll have your indoor herb garden going in no time [8]. When your herbs flower and produce seeds, they are on their way out [13]. Use those beautiful leaves regularly to keep them growing and delay flowering [13].
Harvesting: Enjoying the Fruits (and Leaves) of Your Labor
Harvest herbs regularly by snipping off leaves or stems as needed [2]. This encourages new growth and keeps your plants productive [2]. Harvest frequently to encourage your herbs to produce more leaves for you [2].
Troubleshooting Common Problems: Addressing Challenges
Even with the best care, you may encounter some challenges when growing herbs indoors. Here are some common problems and how to address them:
- Yellowing Leaves: This can indicate overwatering, underwatering, or a nutrient deficiency. Adjust your watering schedule and consider fertilizing [25].
- Leggy Growth: This is usually a sign of insufficient light. Move your herbs to a sunnier location or supplement with grow lights [2].
- Pests: Inspect your herbs regularly for pests like aphids or spider mites. Treat infestations with insecticidal soap or neem oil [19]. Whitefly can be a common pest on indoor herbs, be sure you are checking the undersides of leaves [18].
Expanding Your Herb Garden: Beyond the Basics
Once you've mastered the basics, you can expand your herb garden with more challenging varieties or explore different growing methods:
- Experiment with different herbs: Try growing rosemary, lavender, or chamomile indoors.
- Propagate new plants from cuttings: Many herbs, like mint and basil, are easy to propagate from cuttings.
- Explore hydroponics: Grow your herbs without soil using a hydroponic system.
