so i started collecting plants for my fire escape garden. my vine plant (aka Hermes) is already reaching for the pole. it's kind of creepy. but woohoo! im super psyched! i bought a cactus, two impatiens, a marigold, Hermes and some other leafy thing. tonight im going to find a few more plants at the farmers market and hopefully get some pots. should i keep the impatiens together in a pot and leave the marigold out... im not sure how the whole watering system works... like when a certain kind of plant needs more/less water than others. thanks!
