Select an irrigation hose or pipe meant for drip irrigation. These hoses have holes along their length to allow small amounts of water to leak out into the soil.
Attach the hose to a water source. Use couplings specifically sold for irrigation systems to prevent corrosion or faulty connections and leaks.
Place black plastic sheeting over the soil beneath the plants. This layer aids in the soil's ability to retain moisture and also protects the plants and fruit from splashing. Remove it during the hottest part of the summer because it keeps the soil too warm.
Run your irrigation system only 10 or 15 minutes at a time to keep from overwatering your cucumbers. The soil should easily clump when squeezed in your hand if it is adequately hydrated.
