This time it was okra. At first I declared it was my saved seed. Then, looking closely, there was the amputated stem of a seedling. Then another. Digging, I found more. Curses!
Pre-emptive strike includes wood ashes or diatomaceous earth (DE) dug into and sprinkled on the seed bed. Sow the seeds and put tiny twigs, three or four, around the seed before covering with soil. Look for them when digging the bed. The are 1/2 inch long, brown little caterpillar looking critters. Smush with your fingers.
I sowed generously because they were saved seed and I had not tested for germination rate. Good thing. There were enough survivors to fill in to make for a good crop. And yes, I stuck in twigs to thwart the cutworms. This evening I'll sprinkle the whole area with DE.
