Diy Plastic Container Gardens For Herbs

how to make plastic container for growing herbs

Growing herbs in plastic containers is a fun and innovative way to recycle plastic bottles and create a mini garden at zero cost. It is an ideal way to reuse old plastic bottles and create a small herb garden either indoors or outdoors. To make a plastic container for growing herbs, you will need a plastic bottle, twine, a drill, and a utility knife. After cleaning the bottle, you will need to cut off the top and make drainage holes in the bottom of the bottle. Once complete, fill the bottle with well-draining soil and plant your herb seeds. Place your container in a sunny location, keeping the soil moist, and watch your herbs grow!

Choosing a plastic container

The next aspect to consider is drainage. Herbs thrive in well-drained soil, so ensure your plastic container has multiple drainage holes at the bottom. If you're crafting your planter from a plastic bottle, create several small holes in the bottom using a sharp knife, scissors, or a drill. You can also cut off the top of the bottle, leaving the handle attached, to allow for better air circulation and easier access to the herbs for harvesting.

When choosing a plastic container, opt for one that is lightweight and easy to move. This will give you the flexibility to reposition your herbs to capture the best sunlight or bring them indoors during winter if you're growing perennial varieties. Plastic containers are ideal for this purpose, as they are lighter than alternatives like clay or terracotta.

Lastly, don't forget to consider aesthetics. You can decorate your plastic herb planter with paint, ribbons, or other crafty additions to make it a beautiful addition to your indoor or outdoor space. Whether you hang your plastic bottle planter by a sunny window or create a vertical garden on a wall, your herbs will not only smell and taste great but also add a touch of greenery to your surroundings.

Container preparation

Cleaning and Preparing the Plastic Bottles:

Start by collecting clean, used plastic bottles. These can be leftover juice, milk, soda, or water containers. Ensure that the bottles are thoroughly washed with soap and hot water to remove any residue. Remove the labels, as well as the tops and handles of the bottles, using scissors or a utility knife. Make sure to create a hole in the cap for drainage if you plan to hang the bottles upside down.

Creating Drainage Holes:

Drainage is crucial for the health of your herbs. Use a sharp knife, scissors, or a drill to create several small holes (approximately ¼ inch in size) at the bottom of each bottle. These holes will allow excess water to drain, preventing root rot and ensuring healthy herb growth.

Choosing a Soil Mix:

Select a well-draining soil mix suitable for herb growth. You can create your own mix by combining equal parts topsoil, compost, and coarse sand (such as paver sand). This mixture will provide the herbs with the nutrients they need while improving drainage. Alternatively, you can use a commercial potting mix or create a blend of potting mix, peat moss, and perlite in equal parts.

Filling the Containers:

Once your bottles are cleaned and prepared, fill them with the chosen soil mix. Leave some space at the top of each bottle, and gently pack the soil to create a stable base for your herbs. Remember to always water the soil before planting seeds or seedlings to ensure optimal moisture levels.

Hanging or Placing the Containers:

Decide whether you want to hang your plastic bottle containers or place them on a windowsill or in a sunny location. If hanging, use rope or thread to securely suspend the bottles horizontally or upside down, creating an attractive and space-saving herb garden. If placing them on a surface, choose a sunny spot that receives at least 4 to 6 hours of sunlight daily.

With these steps, your plastic containers will be ready for planting herbs! Remember to consider the water requirements of different herbs and provide sufficient drainage to ensure the healthy growth of your herb garden.

Soil type

The type of soil you use for your herb garden is important as it will determine the types of plants you can grow and how you manage your soil. A soil's pH is a vital factor in a plant's ability to obtain, via its root system, all types of plant foods and essential chemicals. Most herbs will tolerate a pH range of between 6.5 and 7.5, which is fairly neutral. For example, an alkaline soil can produce stunted plants with yellowing leaves.

There are four basic soil types for growing herbs: clay, chalk, loam, and sand. Clay soils are heavy, high in nutrients, wet and cold in winter, and baked dry in summer. This soil type is composed of tiny particles that, when wet, stick together, making the soil heavy and difficult for roots to penetrate. In summer, when dry, clay sets rock hard. Clay soils contain a high proportion of water due to the capillary attraction of the tiny spaces between the numerous clay particles. Clay soils are easily compacted when trodden on while wet. Even though it can be rich in plant nutrients, as they hold nutrients bound to the clay minerals, it is improved by working in extra well-rotted leaf mould or compost. This will improve the structure and allow young plants to become more easily established.

Chalky soils are largely made up of calcium carbonate and are therefore very alkaline. This soil type is typically light with lumps of flint or chalk, well-drained, and often shallow. It is possible to increase the nutrient content by adding compost, but it is difficult to lower the pH into a range more tolerable for herbs. It is also hard to adjust the soil to help it retain moisture. Therefore, it may be easier to grow herbs in a raised bed.

Loam is a mixture of clay, sand, and silt that avoids the extremes of each type and is fertile, well-drained, and easily worked. There are various types of loam depending on the content of clay or sand. They can be clay-loam or sandy loam depending on their predominant composition and cultivation characteristics. A sandy loam is the best soil for growing the largest range of herbs as it is rarely waterlogged in winter, is dry in summer, and is naturally high in nutrients.

When in doubt, it is recommended to reproduce the environment from where the herb originates. For herbs from the Mediterranean, this is a gritty, well-drained soil, and for UK native herbs, it is a moist loam.

Drainage

If you are using a plastic bottle with a cap, make a hole in the cap for drainage. If you are using a plastic container, make several 1/4-inch holes in the bottom of the container with a sharp knife, scissors, or drill bit. If you are using a pot without a drainage hole, you can place a pot liner inside. You can also use decorative foil or plastic pot wraps, but be sure to pierce a hole in the bottom of the wrapper.

It is a myth that a layer of gravel at the bottom of the pot improves drainage. Instead, the water gathers in the soil above the gravel, and only once all the available soil air space is filled does the excess water drain into the gravel.

To keep soil from falling out of large drainage holes, some people use a coffee filter paper over the hole, but this is not necessary.

Container placement

When grouping multiple herbs in one container, ensure they have similar water requirements. Some herbs need to dry out between watering, while others prefer to stay moist. Herbs grown in clay containers may require more frequent watering because they tend to dry out faster. In the summer heat, this could mean watering once or twice a day.

The size of the container also matters. The larger the pot or container, the better the herbs inside will be able to maintain themselves. They can tolerate more abuse, such as lack of water or too much sun, compared to small pots where the soil dries out faster. Terra cotta pots are a good option as they help regulate moisture levels and typically have large drainage holes. They are also budget-friendly and aesthetically pleasing.

If you are limited on space, consider hanging your herb garden. You can hang plastic bottles by the window to create a herb wall garden. This method saves space and showcases your herb garden. Remember to add drainage holes to the bottles before planting.
