Bareroot native trees and fabric pots.

A watering can.

Now I collect seeds and nurse baby trees to plant out. It takes hardly any time from day to day, and I always have something to look forward to. It's the only activity I've found that perfectly embodies the "think global, act local" ethos.

My favourite of all the posts here. I would love to read a how-to for ignorant techies, describing all the details and how it takes hardly any time.
