What to know before buying

When shopping for a watering can, there are a few things to consider. Here, we answer some frequently asked questions.

What size watering can should I get?

As a rule of thumb, the ideal can size should match the size of your plants and it also depends on the number of plants you have. Most cans are in the range of 0.5 to 3 gallons. A higher capacity allows you to water a lot of plants with one fill.

For most users, a 0.5 to 1-gallon can is adequate for indoor or outdoor plans. If you have fewer plants, opt for a lower capacity can. For example, a 0.5-gallon can will be perfect for watering about seven plants.

How often should I water my plants?

Plant or garden maintenance requires regular watering to ensure success. While watering frequency depends on several factors like season and type of plant, it’s important to be consistent to keep your plants looking green.

For example, for outdoor plants, it’s recommended to water them once a day and for indoor plants, every two to three days. You’ll need to water them more in the summer. Avoid overwatering your plants as they are likely to die due to root rot.

Plastic vs. metal: Which is better?

Metal and plastic materials are the typical options for watering cans. Your pick between the two depends on durability and affordability. If you want a durable option, a metal watering can make a great option. In this case, we recommend buying a galvanized metal can.

Plastic cans, on the other hand, are more affordable than their metal counterparts. They’re also lightweight and easy to carry. However, some plastics can contaminate your water, and this can be a bummer if you’re growing edibles.

Our verdict: Which watering cans are best?

Both indoor and outdoor plants need to be watered regularly to look lush and green all year round. Having a plant watering can at hand offers a convenient way for keeping your plants hydrated. Here are our picks that stand out and will suit your needs:

Hopefully, these options will help you find the best watering can to keep your plants nourished and hydrated.
