Q. I am trying to figure out when asparagus goes dormant in the desert. I have been doing some research, but I can’t find information about how to handle the dormancy period in the desert. Any ideas?
This is what you hope will happen in the winter to asparagus. In warmer climates it stays green. Turn off the water to force the plant to go dormant.
A. The usual information about asparagus says it turns
brown, or goes dormant, as weather gets cold. That’s true in Michigan or
Washington state. Sometimes asparagus grown in warm deserts doesn’t turn brown.
It might stay green all winter long.
Wait for
the coldest part of the winter, cut it down like it was brown and turn off the
irrigation. In about a month, irrigate and fertilize again to push a new crop
of spears. For some plants, drought can sometimes substitute for the dormancy
of winter cold.
