I want a no maintenance garden - is that doable ?
The simple answer to that question is NO. There is no such thing as a no maintenance garden anywhere - let alone on a rooftop in Manhattan.
A hot sunny garden !
The rooftop environment
Think about a rooftop garden and the environment that it is in. It bakes in the sun all summer long where it can be several degrees warmer than the ground. Dark containers facing the afternoon sun will reach well above any temperature a root can tolerate.
In winter it gets exposed to cold dry winds and freezing. Since its not planted in the ground, individual planter boxes may freeze solid - affecting roots. These conditions can damage plants and they will need pruning and shaping.
Snow will many times create a heavy burden on plants and misshape them.
Cleaning
At the very least a terrace garden will need to be seasonally cleaned of leaf litter and debris - the drains too! That means a good clean up in Spring to deal with what winter brought, another in Summer for leaf litter, then a final clean up including a prune in Fall.
A doggy pee patch may need washing and rinsing on occasion !
Irrigation
You will need your irrigation lines turned on in spring, visits to adjust the watering cycles in summer, and the system drained and shut off in fall (so the pipes don't burst ). This irrigation work is the very bare minimum.
Fertilizing
You have plants in boxes - they will need fertilizer !!! Irrigation systems are notorious for leaching out fertilizers from the soil - so once very 2 months at minimum - once a month is even better.
Root pruning
With age and growth comes the need for root pruning. As plant roots grow over time the soil gets compacted. This root bound soil will stunt the growth of the plant - flowering too. One has to address this by digging holes (carefully) in the planter and refilling with fresh soil and fertilizer.
Pests !
Oh yes. If you thought bugs and funguses could not find your garden on the 50th floor rooftop - think again! About the only bug we rarely find on a rooftop is a mosquito - probably because their wings are too delicate to fly up and deal with the wind. But don't say it too loudly !!
So plan accordingly - because on occasion you may need the help of one of our NYS licensed pesticide technicians.
A well kept garden.
So put the work in to it that it deserves and you will reap the rewards of a beautiful garden for many years to come.
