I watched -- some cute & simple things! THEN, clicked on others to right and saw some GREAT reminders, & new things, of how to grow things in containers, how to start your garlic in old water bottles! Onions, too. Some are such quick and wonderfully easy starts. Of course, you need dirt

for most but, when you dump tubs of it (potatoes, etc.) it can be reused by adding some composted manures, etc., so not wasted $$. If done in your garden area, fills raised beds, etc. I'm thinking to "collect" all sorts of containers for next year.
Then there's straw bale gardens, lay the whole bag of dirt, cut slits & plant gardens.

Gotta grow before you cook.
