Answer: You may be having a pollination problem. One variety of self-pollinating cucumber to try is Sweet Success (pg 63 of the Burpee catalog). The bitterness problem can be helped by consistent watering and a good organic mulch to keep soil evenly moist. White flies can be controlled by spraying with insecticidal soap. Cucumbers and squash need lots of nutrients, so side dress the vines as they start to run with a 5-10-10 fertilizer.
