How to Build a Mason Jar Herb Garden: 11 Simple Steps

A mason jar herb garden is a charming and practical way to grow fresh herbs at home. It’s perfect for small spaces, environmentally friendly, and adds a touch of greenery to your kitchen or living space. Follow these 11 simple steps to create your own thriving herb garden using mason jars.


Why Use Mason Jars for Herb Gardening?

  • Space-Saving: Ideal for countertops, windowsills, or small spaces.
  • Eco-Friendly: Reuse jars and reduce waste.
  • Aesthetic: Adds a rustic, stylish touch to your home décor.

What You’ll Need

  • Mason jars (1 for each herb you want to grow)
  • Small stones or pebbles (for drainage)
  • Potting soil (herb-specific or all-purpose)
  • Herb seeds or seedlings (e.g., basil, parsley, mint, thyme)
  • Labels or markers (optional for identifying herbs)
  • Small trowel or spoon
  • Spray bottle or watering can

11 Steps to Build Your Mason Jar Herb Garden

1. Choose Your Jars

Select clean mason jars with a wide opening to allow for easy planting and growth. Quart-sized jars work well for most herbs.

2. Add Drainage Material

Place a 1–2 inch layer of small stones or pebbles at the bottom of each jar. This prevents water from pooling around the roots.

3. Prepare the Potting Soil

Use nutrient-rich potting soil that drains well. Mix with compost for added nutrients, if desired.

4. Fill the Jars with Soil

Spoon soil into each jar, leaving about 1–2 inches of space at the top to allow room for watering.

5. Plant Your Herbs

  • For Seeds: Sprinkle a few seeds on the soil’s surface and cover lightly with a thin layer of soil.
  • For Seedlings: Create a small hole, place the seedling in, and pat the soil gently around the roots.

6. Label Your Jars

Use chalkboard labels, stickers, or wooden sticks to identify each herb, especially if planting multiple varieties.

7. Position Your Jars

Place your mason jars on a windowsill or countertop that gets 6–8 hours of sunlight daily. Herbs thrive in natural light.

8. Water Regularly

Use a spray bottle or watering can to keep the soil moist but not soggy. Avoid overwatering, as mason jars lack traditional drainage holes.

9. Rotate the Jars

Rotate the jars weekly to ensure all sides of the plants receive equal sunlight.

10. Prune and Harvest

Regularly pinch off leaves or stems to encourage healthy growth. Use the herbs in your cooking or teas!

11. Monitor Growth

Watch for signs of overwatering, pests, or nutrient deficiencies. If needed, transplant herbs into larger containers as they grow.


Best Herbs for Mason Jar Gardens

  • Basil: A fast-growing herb ideal for sunny spots.
  • Mint: Thrives in indirect light and adds a refreshing aroma.
  • Thyme: A hardy herb requiring minimal maintenance.
  • Parsley: Perfect for windowsills with moderate sunlight.
  • Chives: Easy to grow and perfect for garnishing dishes.

Tips for Success

  • Avoid Waterlogging: Since mason jars lack drainage holes, monitor water levels carefully.
  • Fertilize Lightly: Add liquid fertilizer every 4–6 weeks for nutrient support.
  • Control Temperature: Keep jars away from cold drafts or excessive heat.
