shauna doesn't exactly have a green thumb but, she's managed to keep our small crop of plants alive for more than a year now. we've had a trip planned for a while so she's been worried about how her plants would survive while we're gone. last night, i decided to do a little research. as it turns out, there are many options for self irrigation. the simplest... plastic water bottles! it was super easy, all you have to do is add a small pin hole in the top of the cap, fill the bottle with water and securely place it upside down into the soil about two inches or so. the final touch, add another pin hole to the bottom of the bottle (this relieves the pressure) and you're all set! now her plants will have top notch care while we're gone.
