What damages a watering can and what to avoid
Impact and dropping
Watering cans are robust, but they can be damaged by heavy impacts or drops. A hard knock against stone, concrete, or hard ground can dent the can or deform the spout. In metal cans, dents can affect appearance without affecting function unless they occur near joints or the base.
If a dent occurs at or near the base, it can affect how the can sits on a surface and may influence stability. If impact damage affects the spout, ferrule, or the joint where the spout meets the body, it can alter pouring behaviour or prevent a rose from fitting reliably.
More seriously, impact at joints can cause separation. If the seams or soldered joints are struck hard enough, they can open, allowing water to escape when the can is full.
Handle your can carefully when full. The added weight makes it more vulnerable to damage if dropped, and a full can that strikes a hard edge is more likely to suffer lasting damage than a lighter impact.
Avoid subjecting the can to extreme force
Don't use the can as a step or stand on it. Don't lever pots or other objects with the spout or handle. These actions can transmit forces to joints and seams that exceed their strength, causing separation or cracking.
Treat the handle and cross stay as carrying devices, not leverage points.
Freezing water inside
Covered separately in the seasonal storage guide, but important enough to repeat: emptying the can before winter eliminates the risk of freeze damage.
Water expands as it freezes. If the can contains water and the temperature drops below freezing, internal pressure builds and forces outward at structural weak points. In metal cans, this commonly deforms the base and can eventually cause splitting. In plastic cans, splits typically follow mould seams.
Loose handles and joints at the cross stay
A handle or cross stay that feels loose at its connection to the body indicates the joint is beginning to degrade. This is functional degradation — the connection is no longer secure.
If you notice movement, contact us for advice. A loose handle affects safe carrying and can gradually worsen. It should not be assumed to be normal or tolerable.
Corrosion from liquid feed left sitting
Steel cans exposed to liquid plant feed — particularly feed left sitting in the can rather than poured through and out — suffer rapid corrosion of the zinc coating. Feed contains phosphates that accelerate this process.
Always rinse a steel can thoroughly inside after using liquid feed. Do not allow feed to sit in the can overnight or between uses.
This is particularly critical for unpainted galvanised cans, where exposure of bare steel accelerates corrosion further.
Leaks from the base or seams
If water escapes from the can when it's full and stationary, the sealing has been compromised. This typically indicates impact damage to joints, corrosion that has penetrated the material, or a manufacturing defect.
A leak from the base or seams is not normal wear and requires attention. Contact us with a description of where the leak occurs and how the damage may have happened.
Bottom line
The main threats to your can's longevity are:
• Impact damage to joints and seams
• Freezing water inside
• Liquid feed left in the can without rinsing
• Rough handling or using the can as a tool for tasks other than watering
Avoiding these maintains your can in good working condition indefinitely.
