Horticulture Tips for January

Home Grown  by Keith Reed
Even though our area has received some moisture recently, please remember drought conditions continue. As the warmer days permit, it would be very helpful to water your landscape, especially newly planted turf, trees, or shrubs. Also consider watering mature trees that were showing signs of stress back in the summer. Another potential problem is trees that are growing near ponds that have gotten lower than normal. These trees are accustomed to a consistent supply of moisture and their root system may not be as well developed as one might expect.

For those with tall fescue lawns, 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 tend to smother the turfgrass, depriving it of air and light (and moisture should we get any).

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.

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 for more information. As always, follow label directions carefully when using all pesticides.

Those interested in pecan or grape production should consider enrolling in the Pecan Management or Grape Management courses beginning in February and March. These courses are intended for both new growers and those desiring to increase their knowledge of these crops. The classes are one day a month for 7 (or 8) months. Cost of the program is $250.
