Peach leaf curl is a fungal disease caused by Taphrina deformans. It is one of the most commonly encountered diseases of peaches and nectarines, especially in home plantings. While it primarily affects the foliage, it may also infect blossoms, young twigs, and fruit.

I spend a lot of time asking homeowners to show me their tree butts. Buttress to be specific, but industry lingo shortens it to butt and is described as the dramatic widening of the lower trunk. The buttress of a tree is located beginning at the root flare where the base of the trunk flares out into the root system. How high up the buttress goes depends on the species. For oaks, it may only be two or three foot high. Some tropical trees have buttresses that go up twenty feet!

Within our global pandemic of COVID-19, I hear scientists and doctors talk about recommendations for preventing the spread of disease. After listening to all the human health experts talk, one thing I realized, folks in the plant world have been dealing with “pandemic” type events for a long time.
