How Much Sunlight Do Cucumber Plants Need?
Cucumber plants require full sun to grow into a bumper crop. Semi-shady areas will work, but the plants will not flourish as they will in full sun.
If you are starting your seeds inside, they will also need to be placed in a sunny window sill or on a porch to grow into healthy plants. When they are 2 inches tall, you will need to plant them in your garden to allow them to have adequate nitrogen and full sunlight so they will advance. All fruit-bearing plants need full sun, including tomatoes, peppers, corn and peas.
