We’re heading out for vacation soon. We have a great friend to check in on the cat for us and he’s a very indepent sort anyway. The plants on the other hand . . . after tending to our garden every day since May, we’re having a bit of separation anxiety.
Two friends in our apartment building have graciously agreed to water the plants for us. They need to be watered once a day, twice a day when it is above 90 and dry. Hauling the water up there every night is a big job so we appreciate the help.
To be on the safe side, we’re also using the Plant Nanny. We put recycled soda bottles screwed into terra cotta spikes into our most thirsty pots. They should self-water our favorite plants. The roses and herbs in particular take a lot of water, so this should be a good back up system.
Brooklyn Roof Garden

Hello
My annual food garden is on the roof. It’s so hot up there I have to water everyday. I brought a sprinkler on the roof and hooked up a garden hose from a tap I have in the yard. The water has to go up about 30 feet, it makes it and the sprinkler does the job perfectly. I don’t have to go on the roof every time. Next year I want to hook up my rain collectors with an electric pump to send the water up there, probably connected on a drip system. One can also hook up the whole thing to a timer, to water before sun rise for 15 – 20 minutes. Plants love it!
