Large containers have the power to transform any outdoor space, adding a touch of elegance and beauty to front porches, garden beds, and back patios. They can be filled with a variety of plants, from lush leafy greens to small trees or shrubs, creating a mini forest on a balcony or a tropical oasis in a small yard. However, one of the biggest challenges gardeners face when working with large containers is finding enough soil to fill them. Good quality potting soil can be expensive, and oversized containers require a significant amount of dirt to fill them, making it difficult for those on a budget to create the garden of their dreams.
5 Affordable Materials to Fill Large Planters
1. Tree & Shrub Trimmings
One of the most eco-friendly and budget-friendly options for filling large planters is using tree and shrub trimmings. This method is inspired by the hugelkultur technique, a growing trend in the gardening world that involves stacking layers of biodegradable materials and topping them with potting soil and plants. In the case of large containers, you can use old tree trimmings that have begun the decomposition process. This helps to add nutrients to the soil as the season goes, rather than causing a nitrogen deficiency like fresh logs and branches would.
Many tree trimming companies offer wood chip drop-offs straight to your house for no cost, making this option even more appealing. Simply fill your containers with the trimmings, cover them with soil, and plant your favorite flowers or shrubs. This method not only saves you money on potting soil but also reduces waste and creates a sustainable gardening practice.
2. Empty Bottles & Cans
Another unconventional option for filling large planters is using empty bottles and cans. This method may sound unusual, but it’s a technique that has been used by many gardeners for years with great success. Burying Diet Coke cans in the bottom of planters is a trick that my mom taught me, and it really works. The empty bottles and cans take up space in the bottom of the pot, reducing the amount of soil needed and saving you money.
However, it’s essential to note that this method is only suitable for ornamental plants, as the microplastics in plastic bottles can contaminate edibles like fruits, veggies, and herbs. If you have large planters that you fill with annual flowers or foliage plants every summer, pop a few 2-liter bottles in the bottom of the pot before filling in with your preferred potting mix. Just be sure to leave the caps on the bottles so they don’t collapse under the weight of the soil and cover the drainage holes in the bottom of your containers.
3. Bricks
Bricks are an excellent choice for filling large planters, especially in windy areas. Not only do they hold down pots, especially those that contain small ornamental trees, but they’re also porous, making them a great filler material. However, it’s crucial to ensure that you don’t cover the drain holes on the bottom of the planter, as this can lead to waterlogged soil and root rot.
Keep in mind that filling your containers with bricks will make them quite heavy, so make sure your pots are in the right place before you start planting. This is also an excellent opportunity to reuse old or broken bricks, reducing waste and creating a unique and functional garden feature.
4. Wood Chips
Wood chips are another fantastic option for filling large planters, and they’re free! Many tree trimming companies offer wood chip drop-offs, which you can use to fill the bottom of your containers. This method is not only budget-friendly but also adds nutrients to the soil as the season goes. Simply fill your containers with the wood chips, cover them with soil, and plant your favorite flowers or shrubs.
Wood chips are also an excellent way to reduce waste and create a sustainable gardening practice. They’re easy to obtain, and they’ll save you money on potting soil, making them an excellent choice for gardeners on a budget.
5. Broken Terracotta Pots or Unglazed Ceramic Pots
Another creative way to fill large planters is by using broken terracotta pots or unglazed ceramic pots. These materials are naturally porous, making them an excellent filler material. Simply place the broken pots or unglazed ceramic pots inside your large planter, and fill the space with soil and plants. This method is not only budget-friendly but also adds a unique and interesting texture to your garden.
It’s essential to note that you can also use old or broken terracotta pots as a planter in and of itself, creating a beautiful and functional garden feature. This method is an excellent way to reuse and recycle materials, reducing waste and creating a sustainable gardening practice.
1 Budget-Buster to Avoid
While the materials mentioned above are excellent options for filling large planters, there are some materials that you should avoid using in the bottom of your planters. One of the worst offenders is plastic, specifically plastic bottles and containers. While they may seem like a convenient and easy option, they can contaminate edibles like fruits, veggies, and herbs with microplastics.
Another material to avoid is terracotta pots, especially those with a glazed finish. These pots are not porous, making them a poor choice for filler material. Instead, opt for unglazed terracotta pots or broken terracotta pots, which are naturally porous and can help to improve drainage in your planters.
It’s also essential to avoid using bricks that have been treated with chemicals or sealants, as these can leach into the soil and harm your plants. Always opt for natural, untreated bricks or broken terracotta pots to create a safe and sustainable garden.
Conclusion
Filling large planters can be a challenge, especially on a budget. However, with the right materials, you can create a beautiful and thriving garden without breaking the bank. From tree and shrub trimmings to broken terracotta pots, there are plenty of affordable and sustainable options available. Remember to avoid using materials that can contaminate your soil or harm your plants, and always opt for natural and eco-friendly options.
By following these tips and using the right materials, you can create a stunning and functional garden that will bring joy and beauty to your outdoor space. Happy gardening!
