A garden hose is a long, flexible tube used to carry water from a water source to plants in the garden. It is typically attached to a spigot or faucet. On the other hand, a garden watering can is a container with a handle and a spout used to manually water plants by pouring water directly onto the soil. While a garden hose is more convenient for watering large areas or reaching plants at a distance, a watering can is ideal for targeted watering or for plants in pots or hanging baskets.
