The blackberry vines are growing well. They seem happy in their location, where they get morning and evening sun and filtered sun during the day.
One of the vines had a few blossoms. The seed clusters appear to be drying, rather than forming into berries, so I’m not sure we’ll get a harvest.
I wonder what climate change will mean for these two berry plants. This may, we’ve had such cooler weather interspersed with early heat, and lots and lots of wind. It’s the heat that gets the vines: when our temperatures rise above 100 for days on end, the berries, and many other plants, can’t take it.
For a gardener, climate change means shifting patterns, and what we counted on as cycles in previous years can’t be expected. I’ve been reading, too, that atmospheric moisture has been increasing by four percent recently (See Increased Atmospheric Moisture in Climate Signals.). For local non-natives, like blackberries, this might mean more favorable conditions.
What will it mean for those plants, like prickly pears and saguaros, that have evolved for dry conditions?
