Mom's Decade-Long Practice of Hiding Diet Coke Cans in Flower Pots Saves on Soil Costs - Learn the Secret Method
Laura Walters, a content editor with a background in documentary filmmaking, local news, and television writing, is no stranger to providing gardening enthusiasts with practical and entertaining knowledge. Based in Southwest Ohio, she has been tending to her rustic vegetable patch in Northern Michigan for the past ten years.
Walters offers a wealth of gardening tips, videos, and information through her platform, where she shares her expertise and passion for all things green. One of her innovative suggestions is using recycled materials for container gardening, such as empty soda cans, plastic water bottles, and nursery containers.
However, when it comes to using soda cans, like Diet Coke cans, as a filler inside larger containers, there are some considerations. While it may seem like a cost-effective solution, it's essential to be mindful of the potential consequences.
Metal cans may leach aluminum or paint residues into the soil as they corrode, which could harm sensitive plants or soil microorganisms. Moreover, unlike natural fillers like gravel or expanded clay, metal cans do not provide beneficial aeration or moisture retention and could trap water against roots or interfere with soil structure.
It's generally recommended to use inert, non-toxic materials like broken pottery shards, gravel, or Styrofoam beads as cheap fillers under soil in large pots. Repurposing cans as small containers for herbs or flowers on a budget, following typical DIY planter guidelines, is a more suitable option.
When it comes to using soda cans themselves as planters, the story is different. If properly drilled with drainage holes, they can serve as an affordable and creative planter option. However, be mindful that metal cans can rust over time outdoors, potentially affecting soil quality and plant health.
Walters' mother has been using Diet Coke cans as a container gardening filler for almost a quarter of a century, and her container garden looks beautiful. Despite the absence of direct evidence about using Diet Coke cans specifically as a filler material, this anecdotal evidence suggests that, with proper care and precautions, it can work.
However, it's crucial to remember that filling pots with materials like rocks, Styrofoam, or Diet Coke cans can lead to root rot, especially if the filler material covers the drainage hole in the bottom of the container.
In terms of potting soil, Walters mentions that she has experimented with different brands and found that the basic Miracle-Gro mix performs better than off-brand potting mixes. She advises against using an inferior, inexpensive potting mix and recommends creating a DIY peat-free potting mix at home or purchasing a high-quality soilless mix like Miracle-Gro.
For summer container gardening, Walters' recommended annuals include impatiens and geraniums. She also offers a free e-book "How to Grow Delicious Tomatoes" for signing up for her platform newsletter.
In conclusion, while repurposing Diet Coke cans as containers (with drainage) is an affordable and creative planter option, using them inside pots as filler material is not recommended due to potential chemical leaching and poor physical properties that might harm plant growth. For container gardening on a budget, it is better to use traditional filler materials or other harmless household items repurposed as planters. This ensures plant health without risking contamination that might come from soda can materials.
