Any you particularly liked?

In descending order of difficulty:

Grow your own MOSS GRAFFITI.

Use shower caddies to make a hanging garden

Start a seedling in a lemon rind.

Seedling in a lemon rind is so cute!

And the moss graffiti is very cool.

I like the two coffee-related tips.

10. Use leftover coffee grounds to enrich your soil and repel critters

11. Keep soil from leaking out of your pots’ drainage holes with coffee filters.

Cool. I liked these a lot. I do some already, and I probably won't try the moss, but very cool...
