“The car dropped [Christopher] Walken off at the West Side apartment he shares with his wife of forty-one years, the casting agent Georgianne Walken. In the kitchen, he pointed at an avocado pit suspended by toothpicks in a glass of water, a green taproot reaching downward. “Look, my avocado is growing,” he said. “Isn’t that great? It’s been sitting there for two months, then it did that.”

It looks like POD’s in good company. This fella was started back in January.
Plants On Deck 
Hello! I saw you mentioned in the City Paper and I am very excited about your blog. I grew up in a suburban area of Georgia outside of Atlanta. We had a lot of land and our family of 5 grew so much of our own food and also lived on it year round. So when I moved into Philadelphia, I felt the itch to also grow things and have been for about 9 years now.
I too am an avid container gardener in South Philly and have used many of the tricks you mention. You also have LOTS of information that I have been craving online so I will be playing major catch up! It’s very hard for me to find information particular to container gardening. Mostly the information that I find is about flowers or succulents. Seeing someone who is also doing vegetables and fruits makes me happy!
I’m growing from seed quite a few things this year. We have a new house and so it will be the first time in my new small concrete back yard. This year I am doing loads of herbs, cucumbers, peppers, tomatoes, zucchini, and brussels sprouts. In years past, I’ve attempted berries (couldn’t get bees to my 2nd floor deck), many kinds of peppers, eggplant, herbs (always herbs) and squash.
I am jealous of your melons! I can’t wait to follow your progress this year.
Thanks for your kind words! That’s exactly what I’m trying to do — create a space for urban container gardeners to exchange ideas, tricks, success stories, (and failures, too, I suppose). Good luck with your garden and let me know how things are going for you.
