Aphid Galls Rising on Elms

The leaves of native elms can look a bit bedraggled at this time of the year owing to the rise of pouch-like elm sack galls and the descriptively named elm cockscomb galls. Fortunately, neither of these aphid galls produce significant injury to the overall health of their elm tree host. Unfortunately, these odd-looking plant structures can spoil the aesthetics of their deep green elm leaf platforms.

Yeasty Beasties, Slim Flux, and Other Natural Wonders

Of course, I had a little fun with enhancing the effect.

Friday, June 5 - Virtual Escape to the Forest - Forest Insects: Native and Non-Native

 

The OSU's Ohio Woodland Stewards Program in the School of Environment and Natural Resources (SENR) is offering online Friday's in the Forest during this pandemic.

E-mails and phone calls to horticulture professionals may describe it as rubbery yellowish-green or bluish-black growth rising from the soil; some may just describe it as "the blob."

Beautiful Oak Flowers

Flowers! That is one of many things horticulturalists think of when we think spring. We think of the beautiful flowers of things like Malus, Forsythia, Viburnum, and Quercus.

Ant Wars

"Ant swarms" are most commonly associated with ants mating and the subsequent establishment of new colonies. However, non-native pavement ants (Tetramorium caespitum) may also swarm for a more nefarious purpose: to conduct full-blown, no-holds-barred ant wars.
