As you can see from the attached picture, one of our cucumber plants has what seems to be a dry white stem near the bottom of the plant. The rest of the plant is doing okay, though, and continuing to grow. There is no evidence that we can see of pests. The cucumber was planted in a raised bed full of mixed purchased "Raised Bed Garden Soil" and Tru Leaf Compost. We had a soil text from Penn State both before and after installing the raised bed (i.e., the existing soil on top of which the raised bed was placed was tested in March 2021; after the raised bed was filled with compost and garden soil, that raised bed soil was tested in April). That latter soil test showed soil ph 8, Potash, Calcium, and Magnesium all "above optimum" and Phosphorus at "optimal" range. They recommended applying Urea, but we did not do that as we could not find it in a small quantity (the raised bed is only 4 ft by 8 ft). The cucumber was planted about May 1, 2021. Other cucumber plants next to this one do not have the same stem problem. They are slightly lighter green than the tomato and basil plants nearby though. The raised bed is covered with landscape fabric and watered via a soaker hose. What, if anything, should I do with the white stem cucumber?
