Even though many of us are “social distancing” to avoid a viral infection, we can still go to our gardens and yards to enjoy ourselves. As always, send in your images and questions.

Lis supplied this email, “[I] Found these [mushrooms] in the Shenandoah [National Park] area on a log that was possibly a [tulip poplar]. Any idea what type of mushroom it is? Feels like a rubbery pancake.”
The fungi shown above is also native to Louisiana, and it decays woods and adds organic matter to soil. If there are conks on live trees, then there is decay inside of the trunk. In heavy wind conditions, a tree with this fungal infection may fail and cause damage to property. Sometimes these fungi will go from rubbery to hard in dry conditions.

Jennifer asked for some information, “Attached is a pic of a bush [that] We have in our backyard. It has long sharp thorns, and for most of the summer is green, but in the spring, it gets white flowers. One: I don’t know what it is, and Two: I’m not sure how to care for it. Any help [would be] greatly appreciated.”
Jennifer has a wild American plum in her landscape. This plant makes many suckers and cause large colonies to form. Individual plants can be pruned to form a small tree. There are many problems with wild plum:

“Hello, my name is Anthony… I live in Pineville, and I have some weeds that keep coming back, and I can’t seem to kill them. Here are the best photos I could take. Any help is appreciated.”
Both weeds are grasses and grow during our cool season. Both weeds will disappear when summer temperature enable the warm season grasses to thrive. Herbicides with atrazine or with simazine will control the annual bluegrass, and these herbicides are selective and are safe on desirable turf grass. Herbicide will require the precise use of glyphosate to control dallisgrass because glyphosate is non-selective herbicide and will kill other plants. As always, read the label before applying any pesticide.
