A fall salad garden – Lettuce, radishes, spinach, turnips, mustard, kale and other greens can be planted from mid-August to early September for a fall harvest, Ward Upham of K-State says. Plant slightly deeper than you do in the spring. Water often until seedlings start to emerge, which happens fast in warm soil. You can prevent a crust from forming on heavy soil by sprinkling the row lightly with peat moss, vermiculite or compost, Upham says. “Reduce watering frequency after plants emerge,” Upham writes in the Horticulture 2014 newsletter. “Plants may need to be protected from hungry rabbits and insects.”
Beets also can be planted now.
Dead canes in lilacs – If you have a lilac that has canes that wilt and die in late summer, following evidence of frass around the base of the plant early in the summer, your lilac probably has lilac borers, Upham says. It’s too late to spray, but remove and destroy dead canes to help reduce numbers next year, he says.
You may want to spray for the insect next spring, first when the Vanhoutte spirea is in full to late bloom, probably by about May 1, followed by a second spray four weeks later. Thoroughly spray the lower portion of the stem of lilac or privet, Upham says. Permethrin (Hi-Yield 38 Plus and Hi-Yield Garden, Pet, and Livestock Insect Control) are labeled for borer control, he says.
