The unceasing heatwave gripping the Northeast is quickly moving into the absurd. With temperatures consistently hovering around 100º F there are few places outdoors you would consider pleasant. Especially not a roof top smack in the middle of New York City, straddled by an interstate highway. Despite the Extreme Heat Advisory, we decided to send Andrew back to the Park & Rec Building to check up again on the Sun-Roots.
Andrew was happy to report that the sweat pouring from his brow was more than enough to irrigate the sun-baked Sedums. During conditions like these we continue to be amazed at the ability of Sedum to thrive in such extreme hot and dry conditions in minimal growth media. Stressing times like these are good for the Sedums, it develops their hardiness. It is important not to spoil your green roof plants by irrigating them. They may suffer a little bit, but they will survive and reestablish themselves even stronger for the next heatwave.
