Alright, this year I made a horrible, horrible mistake.
I ran out of plastic flower pots like these...
So, I decided: "hey, why buy new ones if I have tons of tin cans like these in my garage?!.."
And so I planted half of all my teeny, weeny, seedlings in empty tin cans. And then, after about 2 weeks, when I am thinking of planting them outside in the dirt now, I realized: "How am I gonna take 'em out?"
Tin cans are not like flower transplant pots, you can't just squish them and all the soil will come out.
So, now I'm gonna have to pull out the seedlings with no soil around the roots. Oh well, at least the other half of all the seedlings are in plastic water bottles.
Every one makes mistakes, right?
