Soil for growing plants in bottles

Before you put soil in a plastic bottle, you’ll need to consider what your plants need to grow. Regardless of which container you use all plants need drainage, space for plant roots to grow, as well as access to sunlight and water.

The kind of soil that you need to grow plants in bottles or any container depends on the kind of plant that you want to grow. Some plants prefer sandy soil but most plants will grow very healthy in well-drained potting soil. One important thing though is to fertilize the soil regularly.

Drainage – Before placing soil into the empty plastic containers, it is important to make small holes throughout the bottom (or the side, depending on whether the bottle will lay horizontal or vertical) and cut off the top. By poking small holes throughout the bottom, this will allow water to flow through quickly rather than pooling which can make damage such as overwatering.

The bottom of the bottle will need drainage holes to help with percolation of water so that the plant roots always have a fresh supply. You can do so by drilling the holes or by hammering through with a small nail. You will need around 4 to 5 holes.

Once the drainage holes are made, you’ll want to add to this with some gravel. These will further help in naturalizing the container’s drainage process and select gravel rocks that are about pea-sized and not too big. Then, fill enough to cover the bottom of the bottle. Once that is done, you can add your potting soil and choose the nutrient-rich variety here.

Some bottles are flimsy and may not stand the wear and tear of changing weather and temperatures. Select bottles made from durable materials and ensure your vertical garden is secure and won’t fall due to extreme rain or wind.

Sunlight requirement for growing plants in bottles

It’s important to choose a plastic bottle that will allow sunlight to flow shine through. Because of this, clear bottles (or very light colours such as light green) are best for this project. You can also want to consider if you’re hanging bottle vertical garden will be in direct sunlight. Excessive sunlight may overheat the plastic thereby overheating the plants inside.

Irrigation for growing plants in bottles

Your plastic bottle vertical garden will likely have water run-off and can help water the other plants you have, creating a self-irrigation system. Ensure this water run-off won’t disrupt neighbours or incur structural damage.

Factors to consider when constructing a bottle garden

The bottles for your garden wall can hang either vertically or horizontally, depending on your preference. If you have a specific choice, you could design a layout in such an aesthetically appealing way. The most important factors to consider when constructing your plastic bottle vertical garden are;

  • Access to sunlight
  • Protection from extreme elements
  • Use of durable materials
  • Proper irrigation and drainage
  • Viable seeds or seedlings

Mainly, it comes down to time, space, and preference. Ultimately, so long as you create your plastic bottle vertical garden with the key factors we mentioned above in mind, you’re sure to have a beautiful and flourishing garden in no time.

Step 1) Cutting up the bottles – Cut the bottles horizontally on one side and remove the extra piece. The final result should resemble a water trough like the one used by animals on farms. The plants will grow out from here, and it needs to be large enough for you to be able to work. The area between the neck of the bottle and the base is large enough for this space. Ensure the bottle cap is still on to prevent the soil from draining out once you fill it in

You could cut your bottles anywhere between half in size to 2/3rd; it’ll depend on what you’re planting. But don’t go below half, that size is usually perfect for seedlings. As a neat trick, you can hold down the bottle till it’s flat. This makes cutting easier.

Step 2) Poke holes along the side and base of the container to provide drainage holes. Pass the string through the holes closest to the ends.These will be used to hang your garden. Line the interior of the bottle with the paper and then fill in the gardening soil.

Step 3) Transplant your seedlings into the new garden and then add the required amount of water. Hang the plastic garden to whatever area that you see fit around your home.

Bottle gardening techniques, tips, and ideas

Whether you want the beauty of climbing vines across your balcony wall or the simplicity of a few succulents strung across your patio, there are several options available for plastic bottle gardens.

Wall hanging bottle garden – Lay a 2-liter plastic bottle on its side, horizontally, then cut out part of the side.  To hang the bottles, you’ll need to then cut out four small holes, two on each side. They should line up with each other. Using rope, wire, or twine, thread through the holes with and once it’s all the way through, tie a knot in the end. Cut the rope at the desired length and hang your beautiful bottle garden.

Self-watering bottle garden – This option is best if you want to set your bottle garden out. This self-watering bottle garden is easy to make and perfect if you’re going to start small yet yield great results. All you need to do is cut three or four small holes in the neck of the bottle. Then, cut the bottle in half and flip it over, so the neck is now inside the bottom of the bottle.

Bottle garden with herbs – This can easily be worked on over a few short hours. Pick up a small piece of plywood from your local hardware store. Place soil inside the neck of the bottle and a small-sized bottle garden to grow your favorite herbs. It’s good to note that any bottle garden that calls for the soil in the neck of the bottle will require something to clog the opening to ensure the soil doesn’t spill out. We like to use recycled paper loosely stuffed, or you’ll need to carefully poke small holes in the lid and place the cap back on the bottle.
