This method is almost foolproof, but remember to change the water every few days or you’ll end up with a swampy mess.

It’s a small act with big impact: less plastic packaging, fewer trips to the store, and a little green boost right where you make your meals.

Old plastic bottles don’t have to end up in the bin. Snip a bottle in half, insert a wick, add water below and soil above.

This setup keeps leafy greens hydrated, using less water and preventing waste. Imagine a salad growing on your windowsill, with yesterday’s soda bottle as its home.

Laying cardboard and newspaper right on top of grass or weeds lets you skip back-breaking digging. These simple materials block light, smothering unwanted plants below.
