Beyond proper water, fertilizing is a huge and vital key to success for growing cucumbers. Cucumbers, like many common garden crops, need a steady of supply of nutrients to thrive.

What is the best fertilizer to use on cucumbers?

The best cucumber food is well-aged compost. Compost only has 2 percent nitrogen, and it releases slowly over many years. Compost won't cause runaway vegetative growth at the expense of fruit. Instead, it adds nutrient reserves that stay available in the soil long term.

When should I fertilize my cucumbers?

Apply at planting, 1 week after bloom, and every 3 weeks, directly to the soil around the plants. Or, you can work a granular fertilizer into the soil. Do not over-fertilize or the fruits will get stunted.
