Man, the watering question, such a great one and so important; I'm still always wondering about watering and how to improve especially when my plants are inside.
Katrina that is fantastic! Great expression of of your creativity & ingenuity, I think it has us all wondering how we can improve our spaces.
When I only had a handful or so I would set them in pots (w/out drain holes) and let them soak. But that gets to be problematic if there's a sick plant in the bunch b/c I'd share & reuse pots.
Then as I got more I simply drug them all to the bathtub and watered them from the faucet. Eventually I got a compression sprayer & I HIGHLY recommend that if you don't have one already. Makes it easier to mix up fertilizer, direct your spray and thus use your water more efficiently. Did I mention that I used plastic gallon jugs to water/fertilize? Had six of them: fert in, water in, shake, water, over and over making sure the water ran through plenty. This needs to be improved this winter b/c it's a huge task...
NOW in summer, right now, just about everybody goes out. This summer I went ahead and got one of those sprayer contraptions you attach to the hose after adding your mix and spray away though this year I've been letting the rain do more work...thereby neglecting feedings. I just spray spray on the back deck...
...gotta figure out something like Katrina...
