If this is your first time growing, I would start with going to your local farm stand and picking up a small cucumber plant (as opposed to planting seed).
I would plan to devote time at least once a week to tend to your garden.
Also, once you pick the cucumbers, plan to pickle them immediately or within a day or two. Much of pickling has to do with freshness. Once you pick them they begin to start decomposing and that can lead to harmful bacteria in your final product.
Plant cucumber plants in nutrient rich soil about 6-12 inches apart in an area that has plenty of sunlight.
Water daily. Weed around plants as necessary.
Pick when cucumbers firm and ready.
