Leaves
No
– don’t count leaves as either leaves or colored leaves after they have lost all their pigments, nutrients and chlorophyll.
Leaves
: One or more live, unfolded leaves are visible on the plant. A leaf is considered "unfolded" once its entire length has emerged from the breaking bud, stem node or growing stem tip, so that the leaf stalk (petiole) or leaf base is visible at its point of attachment to the stem. Do not include fully dried or dead leaves.Slide4

Yes… and it doesn’t matter why:Summer droughtInsect damage or other stresses
Colored leaves
Photo: Ellen G Denny
One or more leaves show some of their typical late-season color, or yellow or brown due to drought or other stresses. Do not include small spots of color due to minor leaf damage, or dieback on branches that have broken. Do not include fully dried or dead leaves that remain on the plant.Slide15
Colored leavesYes
… and it doesn’t matter how much of the leaf is colored
One or more leaves show some of their typical late-season color, or yellow or brown due to drought or other stresses. Do not include small spots of color due to minor leaf damage, or dieback on branches that have broken. Do not include fully dried or dead leaves that remain on the plant.
