    Good idea. I think I will get started on that when the snow melts next May.

    Great idea… the weight issue could be substantially lessened if shear braces were used… it is a bit dangerous for the structure unless it was built for weight on the roof… but since it is brick it is it is something to maybe brace the corners a bit… at least in Earthquake country like where we live… but I love the idea of urban gardening… very green!

    a green roof will also help keep the roof cooler reducing the amount of energy it takes to cool down stairs

    According to Wikipedia, Alliums (chives, garlic, onions) should not be planted near nightshades (tomatoes, eggplants, peppers)….

    Nice John. Don't forget the cooling benefit of having the containers on the roof absorbing sun energy.

    Gaia insttute makes roof top soil that weighs 280 lbs for 3 ftx 3ftx3ft 1 cubic yd, Tested bt Cornell university

    I did mention the weight thing several times in this episode. 60 lbs was my estimate. but even at 40 lbs a pop, thats some serious weight. That was an old school brick building so it was probably fine in that instance.

    60×80 = 4800lbs = 2.4 us tons plus the weight of any produce grown = a lot of weight. Hey John I think you should put a serious weight warning out there.

    I used to grow a rooftop garden on top of my houseboat. I had dwarf fruit trees, blueberries, strawberries, herbs, and switched between summer and winter vegetable crops as the seasons changed. It was fun! I'm glad to be back on dry land though.

    HELPFUL TIP:

    If you are container gardening on a roof top, with recycling bins, you can drill inch wide holes on the handles of these recycling bins. You then put heavy duty rope through the hole and make a knot under the handle. You can then lower and raise your containers off the side of your roof to the ground.

    Why not garlic, beets, or onions? I grow them all in very shallow beds.

    Another great video! I've designed out my garden for next season, mainly using recycling bin that I got for free at the state recycling plant. If I took a 5 minute or so video walking you through my plan would you give me feed back? I've learned almost everything I know about gardening from your videos, so it would mean a lot to me.

    Thanks — Adam

    I would love to utilize my rooftop but weight is a major concern. What I'd like to find are plants with a high edible content to dirt ratio. In another words, one pot of dirt to grow a lot of plants. Lettuce would not be it but malabar spinach, sugar snap peas, etc. Any other recommendation?

    Drip irrigation is good but sub-irrigation is much better. These planters could easily be made into sub-irrigated planters (SIPs) offering increased production and water conservation. There would be no environmentally unsound runoff or threat of water leaks in the roof. Drain hole containers are clearly wasteful.

    Both water and oxygen are essential for vigorous plant growth.
    SIPs provide both a water and oxygen reservoir. Drip irrigated planters do not.
