It’s a perfect project for both beginners and seasoned DIY enthusiasts. Mason jar herb gardens are space-efficient and customisable and offer a chic, rustic touch to your kitchen or any other living space. Plus, they make for great conversation pieces and thoughtful gifts!
Why Choose a Mason Jar Herb Garden?
Before diving into the step-by-step process, here are some reasons why mason jars are an excellent choice for a DIY herb garden:
- Space-Saving: Mason jars are compact, making them perfect for small spaces such as window sills, countertops, or shelves.
- Aesthetic Appeal: These glass jars add a decorative element to your kitchen or home. Their transparent design allows you to see the soil, roots, and plants grow, adding an extra touch of natural beauty.
- Cost-Effective: Mason jars are relatively inexpensive, and you can even repurpose old jars you might already have at home.
- Mobility: Since they are small and light, mason jars can be easily moved around, making it simple to adjust their exposure to sunlight or change their location as needed.
- Indoor Gardening: If you don’t have a garden or balcony, a mason jar herb garden is the perfect way to bring nature indoors.
Herbs Suitable for a Mason Jar Garden
Before you begin, it’s important to select the right herbs. Not all herbs will thrive in small containers like mason jars. Here are some of the best herbs for a mason jar herb garden:
- Basil: Basil is an excellent choice due to its versatility in the kitchen. It grows well in jars as long as it gets plenty of sunlight.
- Mint: Mint is easy to grow and has a refreshing fragrance, but it can spread quickly, so a mason jar will help contain it.
- Parsley: Parsley is a slow-growing herb that does well in confined spaces and adds fresh flavour to a wide variety of dishes.
- Thyme: Thyme is a low-maintenance herb that doesn’t require much water, making it ideal for indoor gardening.
- Cilantro: Cilantro grows quickly and loves sunlight. It’s a great choice if you enjoy making fresh salsa or other Mexican-inspired dishes.
- Oregano: Another great herb for Italian and Mediterranean cooking, oregano can thrive in smaller spaces and doesn’t need too much care.
Materials Needed for Your Mason Jar Herb Garden
Here’s a list of materials and tools you’ll need to get started:
Materials:
- Mason jars (wide-mouth jars are recommended for easier planting)
- Gravel or small stones (for drainage)
- Potting soil (preferably organic)
- Herb seeds or small herb seedlings
- Activated charcoal (optional but recommended for air circulation and odor control)
- Labels or chalkboard paint (for labelling jars)
- Small shovel or spoon (for filling jars with soil)
- Twine or wire (optional for hanging jars)
- Drill with a small bit (if mounting jars on wood)
Tools:
- Small funnel (optional, but helpful when adding soil)
- Watering can or spray bottle (to water plants without over-saturating them)
- Scissors (if using twine for hanging)
Step-by-Step Instructions for Building a Mason Jar Herb Garden
Step 1: Plan the Location for Your Herb Garden
Herbs need plenty of sunlight to thrive, so the first step is to choose a well-lit spot for your mason jar herb garden. Ideally, your garden should be placed near a window that gets at least 6–8 hours of sunlight a day. A south-facing window is perfect for most herbs, but you can also supplement natural light with grow lights if necessary.
If you’re short on space, consider mounting the jars on a wall near a sunny window or even hanging them from hooks under your kitchen cabinets.
Step 2: Prepare the Mason Jars for Planting
- Clean the Jars: Wash the mason jars thoroughly to remove any dust, dirt, or food particles. It’s important to start with a clean surface to prevent mould or bacteria growth.
- Add Drainage Material: Since mason jars don’t have drainage holes like traditional planters, you need to create a makeshift drainage system to prevent water from pooling at the bottom and causing root rot. Start by adding a layer of gravel or small stones (about 1–2 inches) at the bottom of each jar. If you want to take it a step further, sprinkle a small amount of activated charcoal on top of the gravel. This helps improve air circulation and prevents odours from forming in the soil.
Step 3: Fill the Jars with Potting Soil
- Choose the Right Soil: Use a good-quality potting mix designed for indoor plants. You can find organic mixes that are enriched with nutrients to give your herbs a healthy start. Avoid using garden soil, which can be too heavy and may not drain well in mason jars. Filling the Jars: Use a small shovel or spoon to add soil on top of the gravel layer. Fill the jar about ¾ full to leave room for the plant. Gently press the soil down to remove any air pockets, but don’t compact it too much.
Step 4: Plant Your Herbs
- Planting Seeds: If you’re using seeds, follow the instructions on the seed packet for how deep to plant them. Usually, you’ll want to plant them about ¼ inch deep in the soil. Water the seeds lightly with a spray bottle and place the jars in their designated spot.
- Planting Seedlings: If you’re starting with herb seedlings, gently remove the plant from its nursery container and loosen the roots. Create a small hole in the soil of the mason jar and place the seedling inside. Cover the roots with soil and lightly press it down to secure the plant. Water it immediately after planting.
Step 5: Label the Jars
Labelling your jars helps you keep track of which herbs are which, especially if you’re growing multiple varieties. You can get creative with this step by using chalkboard paint on the front of each jar or simply attaching a label with string or twine.
Step 6: Watering and Care
Herbs need regular watering, but be careful not to overwater them. Since mason jars don’t have drainage holes, it’s easy for water to accumulate at the bottom and lead to root rot. Use a small watering can or spray bottle to water your herbs when the top inch of soil feels dry.
Mason jar herb gardens also benefit from occasional pruning. Snip off the leaves as needed for cooking, which encourages the plant to grow bushier and produce more leaves.
Step 7: Optional – Mounting or Hanging the Jars
If you’re looking for a way to display your mason jar herb garden, consider mounting the jars on a piece of reclaimed wood or hanging them using twine or wire. This adds a vertical element to your garden and can free up valuable counter space.
- Mounting: Drill small hose clamps into a piece of wood, ensuring the clamps fit snugly around the neck of the mason jars. Use screws to attach the wood to the wall near a sunny window.
- Hanging: If you prefer to hang your jars, wrap wire or twine around the neck of the mason jars and hang them from hooks in your kitchen or by a window.
Tips for Maintaining a Healthy Herb Garden
- Light: Ensure your herbs get plenty of light. Most herbs prefer 6–8 hours of sunlight per day. If you notice your plants becoming leggy or pale, it could be a sign they need more light.
- Watering: Be careful with watering. While herbs like moist soil, overwatering can lead to root rot. Check the soil regularly, and only water when the top layer is dry.
- Fertilizing: Herbs don’t need a lot of fertilizing, but you can use a diluted liquid fertilizer every 4–6 weeks to give them a nutrient boost.
- Harvest Regularly: Frequent harvesting encourages new growth. Don’t be afraid to snip off leaves as needed for cooking, just be sure to leave enough for the plant to continue growing.
- Pest Control: Keep an eye out for common indoor plant pests like aphids or spider mites. If you notice any, treat your plants with a mild insecticidal soap.
