How to Grow cucumbers

Prepare soil. Cucumbers are heavy bearers, they require very rich soil: compost or aged manure heap is the best. 

Start seeds directly in the prepared soil outside 2 weeks before the last frost in your area. Place seeds 1" deep in the ground and  keep 1-foot distance between plants.  Cover seedlings with poly when weather is cool.  Water cucumbers regularly thru the whole season.

When plants are about 1-2 feet long, pinch off the tip of each plant to encourage more branches to grow from the main stem.

Plant some blooming flowers in the vicinity, such as marigold, bergamot, sunflowers, lavender, to attract natural pollinators (bees, butterflies) - much needed by cucumbers to produce more.
