A good plastic watering can is one of those gardening tools that is very useful in the garden every day. While I love cute little watering cans and fancy metal watering cans, plastic watering cans are the most used daily in the garden.
Most garden centers sell plastic watering cans. These jars are usually large, holding a gallon or two of water. They also tend to have high-velocity spouts that deliver water faster than watering cans with metal rosettes, sprinkler heads.
A good plastic watering can should have a removable spray head. That said, the tip of the spout should be removable. Most plastic watering cans have a friction fit removable spray head. Find a watering can that is easy to carry, oversized cans or placing awkward handles can make using a watering can less fun.
