* Nutrients: Rubbish piles often contain materials that are harmful to plants, like plastics, metals, and chemicals. While some decomposition might release nutrients, it's more likely to be a mix of harmful and beneficial substances.
* Competition: Rubbish piles attract weeds and other unwanted plants that would compete with any wild grain trying to grow.
* Soil Conditions: Rubbish piles can alter the soil structure and composition, making it difficult for seeds to germinate and roots to grow.
* Pollution: Rubbish piles can attract pests and diseases, and they may leach pollutants into the surrounding soil and water, negatively impacting plant growth.
Instead of flourishing, wild grain would likely struggle to grow near a rubbish pile.
It's important to remember that wild plants are best left to grow in their natural habitats, which are typically less polluted and provide the ideal conditions for them to thrive.
