Three easy steps to prep your metal watering can for winter
As gardeners, we're brilliant at fussing over our plants as winter approaches – wrapping, mulching, bringing tender specimens indoors. And believe it or not, your watering can has earned that same level of care. Think of this as its yearly MOT. It's been working faithfully all season, and a little winter preparation now means it'll still be in top condition come spring.
And for us, it’s really simple: remove your roses; give the can a clean and remove any water. Then you’re ready to find somewhere dry and clean to store it, until you need to use it again in the spring.
While this guide was written with Haws cans in mind, the same advice applies to any metal watering can. We believe in caring for all cans equally, although we might have a favourite or two.
If you’ve got a plastic watering can, they also need a little prep for winter – you can read our guide to winterising plastic watering cans here.
1. Remove any roses
A rose is an attachment that shapes and softens the water poured from a watering can, placed on the end of the spout. As temperatures swing between mild days and freezing nights, metal also expands and contracts. A rose left on the spout through these cycles can become fused in place, sometimes to the point where it can't be removed without damage.
The rose itself benefits from a little TLC, too. Because if corrosion sets in, it can clog the carefully positioned holes. Once removed, give it a clean with an old toothbrush, dry thoroughly, and tuck it away somewhere you'll remember come March. Your spring self will thank you when everything simply slots back together.
2. Clean and dry your can
After your last autumn watering, give your can a proper send-off with a once-over before hibernation. Warm soapy water, a soft brush and a clean cloth work wonders – pay close attention to seams, the spout opening, and anywhere debris likes to collect as you go. Soil residue, algae, and hard water deposits left over winter can encourage rust, and these spots are where slow leaks often start.
Think of this as your watering can's annual check-up or MOT. Inspect seams and handles for any signs of wear, scratches, or worn spots in the finish. You can even crack the WD-40 out and give the outside a light spray for extra protection.
Once cleaned, it's time to dry. Water left inside is how most cans meet an untimely end, so this is the most essential step. It expands by about 9% when it freezes, and in the confined space of your watering can, that expansion has to go somewhere – sometimes straight through the base. Even a tiny puddle can cause damage.
To avoid any issues, turn the can upside down and let it drain completely. Give it a good shake, leave it inverted for an hour or so, then check it's bone dry. Proper draining and drying prevent the vast majority of cracks and leaks.
Go the extra mile with a light polish: polishing anything copper or brass before storage prevents tarnishing and adds a protective layer against corrosion. Our Haws Polishing Kit includes everything you need – it keeps your brass roses functioning at their best and your copper and brass cans looking pristine.
3. Store it somewhere safe
The final step is putting your can away somewhere for winter. Indoor storage in a garage, shed, or basement is ideal – somewhere temperatures stay above freezing and rain can't reach. That way, your can stays dry, protected, and just as you left it. Store it upright to prevent dents and warping.
But, if outdoor storage is unavoidable, make sure to store the can upside down and undercover. This prevents rainwater from collecting inside – one of the most common causes of base leaks. A protective bag or cover adds extra insurance, and tucking a small silica gel packet inside helps absorb any moisture that sneaks in.
Protecting your investment for years to come
Your Haws watering can is engineered for generations of use. Traditional craftsmanship, quality materials, and thoughtful design all contribute to that longevity. But even the finest engineering needs a helping hand when it comes to winter conditions, so give your can the winter send-off it deserves.
