Milk Jug Gardening: Repurposing Old Containers


Milk jug gardening is a creative and eco-friendly way to grow plants using old milk jugs. This gardening technique is perfect for people with limited space, such as those living in apartments or urban areas, and it offers an easy and cost-effective way to start a garden. In this guide, we’ll explore what milk jug gardening is, its benefits, and how you can get started. Whether you’re a seasoned gardener or a complete beginner, milk jug gardening provides a fun and sustainable way to grow your own plants.

What is Milk Jug Gardening?

Milk jug gardening involves using empty milk jugs as planters for growing various types of plants. By cutting and repurposing these plastic containers, you can create mini-greenhouses or simple pots for your plants. This method is not only environmentally friendly but also helps save money on buying new gardening supplies.

Benefits of Milk Jug Gardening

Eco-Friendly Practices

One of the main benefits of milk jug gardening is its positive impact on the environment. By reusing old milk jugs, you’re reducing plastic waste that would otherwise end up in landfills. This simple act of recycling helps protect our planet and promotes sustainable living.

Cost-Effective Solutions

Gardening can sometimes be an expensive hobby, but milk jug gardening offers a budget-friendly alternative. Instead of purchasing expensive pots and planters, you can use milk jugs that you already have at home. This way, you save money while still enjoying the pleasures of gardening.

Space-Saving Techniques

Milk jug gardening is perfect for those with limited space. Whether you have a small balcony, a tiny backyard, or just a sunny windowsill, milk jugs can be placed almost anywhere. Their compact size makes them ideal for urban gardening, where space is often a constraint.

Getting Started with Milk Jug Gardening

Ready to dive into milk jug gardening? Let’s start with the basics. Here, we’ll walk you through the materials you need and the steps to prepare your milk jugs for planting.

Materials Needed

Before you begin, gather the following materials:

  • Empty milk jugs (cleaned and sanitized)
  • Scissors or a utility knife
  • Soil (suitable for the type of plants you want to grow)
  • Seeds or seedlings
  • Watering can or spray bottle
  • Marker (for labeling)

Choosing the Right Milk Jugs

Not all milk jugs are created equal. When selecting milk jugs for your garden, look for those made of sturdy plastic. Jugs with handles are especially useful as they make moving and watering easier. Avoid jugs that have cracks or damage, as these may not hold soil and water effectively.

Additional Tools and Supplies

While milk jugs are the main component of this gardening method, a few extra tools can make the process smoother. A good pair of scissors or a utility knife is essential for cutting the jugs. You’ll also need a reliable source of soil and some seeds or seedlings of your choice. A watering can or spray bottle will help keep your plants hydrated.

Preparing the Milk Jugs

Now that you have your materials ready, it’s time to prepare the milk jugs for planting. This involves cleaning, cutting, and shaping the jugs to create the perfect environment for your plants.

Cleaning and Sanitizing

Start by thoroughly cleaning the milk jugs to remove any leftover milk residue. Rinse them with warm water and soap, and let them dry completely. Sanitizing the jugs is also a good idea to prevent any bacteria or mold from affecting your plants. You can do this by soaking the jugs in a solution of one part bleach to nine parts water for a few minutes, then rinsing them thoroughly with clean water.

Cutting and Shaping

Once your jugs are clean and dry, it’s time to cut them. Use scissors or a utility knife to carefully cut the jug around its middle, creating two halves. The bottom half will serve as your planter. If you’re making a mini-greenhouse, leave the top part attached to act as a lid that can be opened and closed. Be sure to poke a few small holes in the bottom for drainage.

With your milk jugs prepared, you’re now ready to start planting!

Choosing Plants for Milk Jug Gardening

One of the exciting parts of milk jug gardening is deciding what to grow. Milk jugs can accommodate a variety of plants, from vegetables and herbs to flowers. Let’s explore some of the best options for each category.


Milk jugs are perfect for growing certain vegetables, especially those that don’t require a lot of space for their roots. Here are some great options:

  • Lettuce: Lettuce grows quickly and doesn’t need deep soil, making it an ideal choice.
  • Radishes: Radishes are another fast-growing vegetable that thrives in milk jugs.
  • Spinach: Spinach is easy to grow and can provide a continual harvest.
  • Cherry Tomatoes: While regular tomatoes need more space, cherry tomatoes can do well in a milk jug if you provide support for the plant as it grows.


Herbs are well-suited for milk jug gardening because they generally require less space and can thrive in containers. Some popular choices include:

  • Basil: Basil grows well in containers and can be harvested continuously.
  • Parsley: Parsley is hardy and easy to grow in milk jugs.
  • Mint: Mint spreads quickly, so a contained environment like a milk jug is perfect for it.
  • Chives: Chives are low-maintenance and provide fresh flavor for your cooking.


If you prefer to grow flowers, milk jugs can accommodate many varieties that add color and beauty to your space. Consider these options:

  • Marigolds: Marigolds are vibrant and help deter pests.
  • Pansies: Pansies are hardy and can tolerate cooler temperatures.
  • Petunias: Petunias provide a long-lasting bloom season and come in many colors.
  • Nasturtiums: Nasturtiums are easy to grow and their flowers are edible.

Planting and Care

Once you’ve chosen your plants, it’s time to get them into the milk jugs and start caring for them. Here are some essential tips for planting and maintaining your milk jug garden.

Soil and Fertilizers

Choosing the right soil and fertilizers is crucial for healthy plant growth.

Soil Types

For most plants, a good quality potting mix works well. Potting mix is light, well-draining, and provides the necessary nutrients. You can also make your own mix by combining equal parts of peat moss, perlite, and compost.

Organic Fertilizers

Using organic fertilizers helps promote healthy growth without harming the environment. Consider adding compost, worm castings, or fish emulsion to your soil. These natural fertilizers provide essential nutrients and improve soil structure.

Watering Techniques

Proper watering is vital for the success of your milk jug garden. Here’s how to ensure your plants get the right amount of water.

Self-Watering Systems

You can create a self-watering system by using two milk jugs. Cut one jug in half, poke a few holes in the bottom, and place the bottom part inside the other jug. Fill the inner jug with potting soil and your plant(s). Fill the outer jug with water, and the inner jug will draw water up as needed through capillary action. This method helps keep the soil consistently moist without overwatering.

Manual Watering Tips

If you prefer manual watering, use a spray bottle or a small watering can to gently water your plants. Make sure the soil is evenly moist but not waterlogged. Check the moisture level by sticking your finger about an inch into the soil; if it feels dry, it’s time to water.

Sunlight and Temperature

Ensuring your plants receive the right amount of sunlight and are kept at the proper temperature is key to their growth.

Ideal Sunlight Exposure

Most vegetables and herbs need at least six hours of sunlight per day. Place your milk jugs in a sunny spot, such as a south-facing window, balcony, or patio. If you don’t have enough natural light, consider using grow lights to supplement.

Temperature Control

Milk jug gardening is adaptable to different seasons. In colder months, you can bring your milk jugs indoors or use them as mini-greenhouses to protect your plants from frost. In warmer months, be mindful of extreme heat and provide shade if necessary to prevent your plants from wilting.

Advanced Milk Jug Gardening Tips

As you gain experience with milk jug gardening, you might want to try some advanced techniques to enhance your garden’s productivity and sustainability.

Companion Planting

Companion planting involves growing certain plants together to improve growth and deter pests. Here are some effective combinations for milk jug gardening:

  • Tomatoes and Basil: Basil helps repel pests that target tomatoes and can improve their flavor.
  • Carrots and Radishes: Radishes mature quickly and can help loosen the soil for carrots.
  • Lettuce and Chives: Chives can repel aphids, which often target lettuce.

Vertical Gardening with Milk Jugs

If you’re short on horizontal space, consider vertical gardening. You can stack or hang milk jugs to create a vertical garden. This technique maximizes space and can be visually appealing. Use a sturdy frame or trellis to support the stacked jugs and ensure they receive adequate sunlight.

Recycling and Reusing Milk Jugs

Continuing the cycle of sustainability, you can recycle and reuse milk jugs in various creative ways:

Creative Reuse Ideas

  • Seed Starters: Use the bottom halves of milk jugs as seed starters. Once the seedlings are ready, transplant them into larger containers or the ground.
  • Watering Cans: Convert a milk jug into a watering can by poking small holes in the lid.
  • Garden Labels: Cut up old milk jugs to create durable garden labels for your plants.

Recycling Programs

Participate in local recycling programs to dispose of any milk jugs you can’t reuse. Many communities have recycling centers that accept plastic jugs, ensuring they are processed and reused in an environmentally friendly manner.

Common Challenges and Solutions

Like any gardening method, milk jug gardening has its own set of challenges. Here are some common issues and how to address them effectively.

Pest Control

Pests can pose a problem, but several natural solutions are available to keep them at bay:

  • Neem Oil: Spraying neem oil can help deter a variety of pests without harming your plants.
  • Companion Planting: Certain plants, like marigolds and basil, naturally repel pests and can be grown alongside your main crops.
  • Handpicking: For larger pests such as caterpillars, manually removing them from your plants can be very effective.

Disease Prevention

Keeping your milk jug garden healthy involves preventing and managing plant diseases:

  • Proper Spacing: Ensure your plants are not overcrowded. Good air circulation helps prevent fungal diseases.
  • Clean Environment: Regularly clean your milk jugs and remove any diseased plant material to prevent the spread of pathogens.
  • Watering Techniques: Water the base of your plants rather than the foliage to reduce the risk of mold and mildew.

Weather-Related Issues

Weather can impact your milk jug garden, but with some planning, you can mitigate these effects:

  • Frost Protection: In colder months, cover your milk jugs with their tops to create a mini-greenhouse effect, protecting plants from frost.
  • Heat Management: During hot weather, provide shade and ensure your plants are well-watered to prevent wilting and stress.

I have been fascinated with gardening and growing plants of all types. My parents and grandparents had green thumbs and grew all types of flowers, fruits and vegetables. I have always followed the "old ways" practiced by them and to the maximum extent possible have tried to avoid the use of chemicals in my garden. I hope to be able to help others to do the same.
