Coffee Filters Also Filter Soil

By all means, put a coffee filter in the bottom of your flower pot, but do you really need to use a fresh one?

If you’re the slightest bit up-to-date about houseplants, you know you don’t have to put a drainage layer of drainage gravel or potshards at the bottom of the pot when you repot a houseplant. Plants actually grow even better without a drainage layer! However, it’s rather annoying to see soil particles flow out of the pot and into the saucer when you water a freshly repotted plant. What can you do about that?

On the Internet you’ll often see an interesting tip suggesting you use a coffee filter to prevent soil particles from flowing out of the pot. And why not? It’s certainly easy enough: you simply place the filter at the bottom of the pot and then fill it with potting mix. And it works very well… any excess water flows out, but the soil remains in place. Problem solved, but …

Usually in the picture accompanying the text, you’re shown a brand new coffee filter! What a waste!

A recycled filter will work just as well!

Disposable coffee filters aren’t particularly cheap. It seems to me that, since you’ve paid for them, you might as well use them for their original purpose, to filter coffee. Afterwards, dump the coffee grounds into the compost and use the dirty filter to cover the bottom of the pot. You don’t even need to rinse: coffee grounds are not toxic, after all. You’ll soon discover a pre-used filter works just as well as a new filter.

Two birds with one stone: bravo!
