Enjoy pottering around the garden with the best watering can. It's the most convenient way of watering outdoor plants. But, you do have to weigh up whether to go for a traditional metal watering can that will last a lifetime, or a considerably lighter plastic version that won't have the same longevity.
The key benefit of a watering can over a hose pipe is that it offers more precise and measured watering. It prevents overwatering and minimises damage to delicate plants and hanging baskets. Although there's manual effort involved, it's an effective way of rationing watering during heat waves and hose pipe bans.

When you need to water your outdoor plants, “you can’t beat a trusty watering can”, says Garden Answers contributor, Geoff Hodge. The best watering can comes in handy when you need to apply liquid feeds to your plants and weedkiller to the ones you want to see the back of. Geoff recommends buying a second watering can specifically for your weedkiller. After all, you don’t want to have any mix-ups. Historically, water cans have been made from galvanised steel, but plastic has taken over as it's lighter and less expensive.
We’ve rounded up a wide range of the best watering cans for every requirement. We’ve given our thoughts on the best plastic and best metal watering cans for your plants. Scroll to the FAQ section where Geoff gives further guidance on on the features and benefits of outdoor watering cans and how best to store them.

It’s built for outdoor use, so you don’t constantly have to walk to the tap. It comes with a convenient sprinkler head for watering mature plants.
Customer Review: “It does the job. I found it slightly heavier empty than expected and the handle is slightly too big for me, but still managed to carry it when full.

Customer Review: “I am delighted to see the style has not changed as I have had another one for more than 41 years. It has only just lost the plastic end, where the nozzle fits in - the new one is reinforced with a brass end. A great product obviously and very sturdy. I look forward to using it.”

This is the ultimate metal watering can.

FAQs
What do I look for in a watering can?
Weight – A lighter can is easier to carry around when you’ve filled it up to the brim.
Balance – This is important as it can affect all aspects of utilising your new can: holding, carrying and pouring. Modern Gardens recommends reading reviews before you buy – or go into a store. Geoff advises, “If it feels awkward when empty, it’ll only feel worse when full".
Handle – A handle should be strong, solid and comfortable. If a handle has been poorly designed, it’s going to be uncomfortable to use for longer lengths of time.
Mouth - With a wider opening, you can easily fill a can from a water source. However, you’ll notice that a narrow-er opening prevents spilling. So, finding a balance here should help.
Cross Bar – To make your watering can much easier to carry and use, most designs will feature a cross bar (or second handle) at the top, making the experience well-balanced and not front-heavy.
Rose – Believe it or not, a watering can’s sprinkling spout is often referred to as a 'rose'. Cans with a one-piece spout and rose tend to be cheaper and less efficient. Watch out for a quality rose.
How do I store my plastic watering cans?
Though cheaper and full of colour, thinner plastic watering cans won’t last forever outside. Geoff explains that “Cold, frost and high UV levels damage and degrade them”. However, he advises that a good-quality, thick plastic watering can “should last as long as metal ones do”.
To avoid distortion:
• Empty it between uses
• Store it upside down
• Don’t leave it outside during cold weather – especially with water inside
What is a watering can rose?
Geoff has given us some expert advice on each type of rose.
Metal Roses – These usually come with metal watering cans and are generally made of brass or copper. Whereas, plastic cans are kitted out with roses of plastic, metal or both. Geoff says, “As long as the rose has been constructed and welded correctly, metal roses are less likely to leak.”
Plastic Roses – You’re faced with a few advantages and disadvantages with a plastic rose. Though you can remove the front easily to clean out any clogs in holes, they do often leak or dribble. "The best watering cans have a built-in water filter, which prevents the rose blocking,” adds Geoff.
Removable Roses – Whether screw-in or push, roses need to be easy to remove. However, they shouldn’t be so loose that they can’t take the weight of water when pouring and falling off, “especially when watering seedlings and young plants".
Hole Size – Hole size will differ between roses. Large holes deliver the water faster, so watering gets ticked off the list a little quicker. However, the larger droplets could damage seedlings. Geoff advises using a rose with smaller holes, as this will be better suited to young plants.
Downspout – Some watering cans have a downspout, which Geoff says makes watering pots and containers easier because water can be directed at the soil or compost exactly where it’s needed.
Up or Down? - Oval-shaped roses can be swivelled to face up or down. Facing up, the water comes gentler and finer – “better for seedlings and young plants”. This way, it won’t disturb the compost. On the other hand, facing down, the water is delivered faster, and cans with a round rose simply water forwards, with no change in speed or flow.
