bad day for ferns

After three weeks of days in the 60s the last two have pushed into the 80s. It’s the kind of intensely sunny spring weather that makes people productive or delirious. Next door they’re playing basketball and downing beers, and here at home John and I have been getting a final coat of paint on some steel stairs to the roof deck that had started to fade and show some rust spots. For us, the beers and margaritas will flow later this afternoon, when we go over to Mason’s and Carlos’s for dinner.

What is a great day for humans hasn’t been so kind on the Australian tree fern, Cyathea cooperi that we put in the ground last fall.

Three weeks ago we had a weekend like this one, suddenly sunny and hot after a long period of cool weather. The plant wasn’t used to the heat, and the last set of fronds suddenly browned.

Fortunately the fern was producing a more fronds at the time, and they since unfurled into a gorgeous new set. Hopefully that hot weather prepared the plant for more sun and heat, and that the new set of fronds doesn’t dry up like the last ones did. We should find out in a few days.
