What's New - Fall 2021

Fall Needle Shedding - It's Natural!

Every fall Earth-Wise receives phone calls from customers concerned about the browning needles on their pine, spruce and fir trees. Not to worry, this is a normal process. Depending on species, location and overall health of the tree, conifers typically hold on to needles for 3 – 7 years. Older needles become less efficient at photosynthesis due to shading from new growth and excess wax buildup; as they are no longer productive for the tree, they are shed.

Cottonwood Leaf Beetle is a Real Pest

This summer, the Earth-Wise staff observed a new, unwelcome addition to the Roaring Fork Valley - the cottonwood leaf beetle. This pest feeds on cottonwood leaves as both a larva and adult, skeletonizing leaves and causing chewing injuries. From a distance, this damage will appear as a general browning of the leaves. Upon closer inspection, the skeletonized leaves are easily seen.

Until this year, damage in Colorado has primarily been located in the eastern half of the state, but recent warm winters have probably contributed to this insect’s migration into the mountains. Earth-Wise offers soil injections and foliar spray options to control cottonwood leaf beetles.
