Horticulture Tips for January
While most gardeners busy themselves this time of year going through the newest seed and plant catalogs, there are also a few landscape tasks that can be undertaken when the weather allows.
- This is a good time to remember to go out and stir around any tree leaves still remaining on the ground. Heavy accumulations of leaves will smother the turfgrass, depriving it of air and light.
- If you have plants that have suffered from heavy infestations of scale insects, consider making a dormant oil application when the daytime temperature is over 40 degrees. Do not apply dormant oil to evergreen plants as damage will result. If you’ve planted new crape myrtles within the last two or three years, examine them closely for signs of scale as a new pest, the crape myrtle scale, has made its way into our area.
- Warm January days are a good time to control winter broadleaf weeds in your dormant bermudagrass lawn. Use a combination of a broad leaf control product and a non-selective product containing glyphosate. This is a very good weed control combination but ONLY in specific situations. Please see OSU Factsheet HLA-6421(PDF/Mobile) for more information. As always, follow label directions carefully when using all pesticides.
- If you have an interest in pecan or grape production, consider enrolling in the Pecan or Grape Management courses beginning in February and March at the Cimarron Valley Research Station in Perkins. These courses are intended for both new growers and those desiring to increase their knowledge of these crops. The hands-on classes meet one day a month for 7 (or 8) months. Cost of the program is $250. Contact Stephanie in the OSU Horticulture department for more information at 405-744-5404.
