Hass fears 109 degrees.

Reed pays little attention to such temperatures.

When you see comparisons between avocado varieties, you see the taste discussed, the size of the tree and fruit, whether it’s an A or B flower type, and how sensitive to cold a particular variety is. Less often do you hear about a variety’s sensitivity to heat.

Having just gone through a record-setting heat wave — a zenith of 109.8 degrees on June 20 — my many varieties showed a spectrum of responses to the intense temperatures.

The most sensitive varieties to that heat were the Hass and Fuerte, whose new leaves shriveled like plastic held to fire. In the middle were the varieties of SirPrize and Sharwil, which had blackening and curling on some new leaves. And the toughest were the Pinkerton, Lamb, and Reed. They showed nearly zero evidence of having been uncomfortable under such a terribly strong sun.
