1- a screenhouse or greenhouse. This prevents the pickleworm moth from destroying the cucumbers. Plus I suspect the plants respond to the extra heat and wind protection. While I've gotten a few cucumbers in the past, mostly hit & miss, I've never before had reliable cuke harvests.
2- variety. Since I'm growing them in a greenhouse, which not only excludes the pickleworm moth but also honeybees, I'm growing a parthenocarpic variety. This is a variety that produces cucumbers without needing pollination. The one I choose to try first is called Socrates. It's a winner for me. I plan to try other parthenocarpic varieties, but it looks like Socrates will be a regular resident here. I'm also trying a standard pickling type that I am hand pollinating, but frankly it's too much bother.
I opted to go for a full blown greenhouse for a couple of reasons. I wanted to grow a lot of cucumbers. So I needed the space. Could a home gardener have success with something smaller, say a small screen cage? Probably. It would be worth a try.
I'm still working out the kinks of growing cukes in a greenhouse. I've got the trellising down ok, but I'm still working out the watering/fertilizing thing. And wondering when powdery mildew will show its ugly head.
