No rain, no gain — Predictions for rain late this week didn’t pan out, so be sure to water if your landscape needs it, and pull weeds and do other outdoor chores while the sun shines. This is the last weekend before daylight saving time ends next weekend (Nov. 1).
Dandelion control — Late October through early November is the best time to kill broadleaf weeds such as dandelions, Ward Upham of K-State says. On a day that is 50 degrees or warmer, apply the herbicide 2,4-D or combination products that contain 2,4-D, MCPP and Dicamba (Trimec, Weed-B-Gon, Weed-Out), Upham says. Weed Free Zone (or Speed Zone) contains the three active ingredients plus carfentrazone and is more effective when temperatures are on the lower side, Upham says.
Needle drop — “Very noticeable” natural needle drop from evergreens such as pines and spruces has started to be seen, Upham says. Interior needles that are 2 to 4 years old turn yellow, then brown and then fall off every year, he says. Be sure that only the older needles are dropping; the ones on the tips of branches should look fine, and there should be no spotting or banding on the needles that are turning yellow. If you notice something else, take a sample to the Extension for diagnosis, Upham says.
Raining worms — If you’ve seen tiny white worms falling from pin-oak trees, they are the larvae of the oak vein gall midge, says Upham and extension agent Matthew McKernan, who has recorded some of the “rain.” The worms apparently cause no damage.
Never miss a local story.
No black walnuts — The tremendous drop in temperature last Nov. 10 killed this year’s black-walnut harvest, Upham says. The same is probably true for acorns. Rains this year should make for a good harvest next year though, he says.
Manhattan daylily hybridizer — Ann Redmond, a daylily hybridizer from Manhattan, will be in Wichita on Monday to talk about hybridizing at a meeting of the Prairie Winds Daylily Society. The meeting, the last of the year, will be at 7 p.m. at Botanica, and is free and open to the public.
“Why Plants Are Bad for You” — Karl Miller, owner of Lark Label plant signs, will be at Botanica on Wednesday to give a tongue-in-cheek talk about “bad” plants. The lunchtime lecture, at 12:15, is included in Botanica admission. Lunch will be for sale for $8 from 11 a.m. to 12:15 p.m.
