While garden mirrors causing fires are a common concern, gardeners face quite a few issues while picking and positioning them. Let us discuss some potential issues that one may face with outdoor mirrors.
Are Garden Mirrors Safe?
Although garden mirrors are perfectly safe, one should avoid placing them under direct sunlight. This is because of various reasons.
A mirror can magnify the heat that it receives from the sunlight. And if it constantly receives sunlight, and the heat gets projected onto an object, it can cause a fire.
If you are worried about your garden catching fire, there are a few other things that you should consider. Here is how mulch may also be a fire hazard.
And while the chances of causing fire are quite unlikely, mirrors may also impact bird flight and safety. So, if you are someone who wishes to build a garden that birds frequent, you might want to avoid garden mirrors.
The reflection in the mirror can confuse the birds, which can even cause them to fly right into the mirror, which can cause serious injury or even death.
However, if you still wish to install garden mirrors, you must be extremely careful while positioning them. It would help if you observed the movement of birds to get an idea of where they flock and fly. This will help avoid the spots that your feather friends most use.
Usually, patio corners and within hedging or climbing plants are spots preferred for garden mirror placement.
Here are a few tips that can help in avoiding any mishap:
- Consider putting stickers on the mirrors
- Frost the surface
- Avoid polishing the mirror, allowing the material to weather over time
How to Position Garden Mirrors?
No matter what kind of garden mirror you use, it all comes down to its positioning. Placing them in shady or dappled light spots will help you make the most out of your garden mirrors. This will ensure that the mirrors do not cause fires and are not in the way of birds.
Other than this, strategically placing your outdoor mirrors will also help bring a new dimension to the space. You will be able to highlight all the beautiful aspects of your garden while creating a greater sense of space and light.
You would not want to reflect your garden’s brick wall or drain pipes. You would want to reflect trees, shrubs, greenery, sculptures, garden art, or water features like ponds. This would help you add more depth and visual appeal to your garden.
What Kind of Mirrors Can Start a Fire?
A concave mirror can start a fire if placed in direct sunlight. Since the concave side of the mirror has a real focal point, a parallel beam of light hitting the surface will have a point of incidence, and the rays will end up meeting the focal point. Thus, the mirror can intensify the rays, which can start a fire on anything combustible.
What Material is Best for Garden Mirrors?
Garden mirrors are also made up of glass or acrylic and are quite sturdier, which means they are also heavier. Thus, if knocked, they may hurt someone.
Acrylic mirrors are lighter than glass mirrors, making them a perfect choice for wooden fences that might not hold heavy and bulkier mirrors. They can easily be glued or screwed into a flat surface. They can also be cut into any size or shape.
But on the other hand, non-acrylic mirrors can stand well to scratches. All you would need to do is seal its edges, weatherproof the mirror and protect it from rusting.
Their surface is much harder, which makes them less susceptible to scratches from foliage and animals.
No matter which mirror you choose, it is essential to ensure that it is secured well, as it is more likely to be exposed to harsh weather conditions like strong winds and rains.
Although acrylic mirrors are around ten times stronger than glass and are less prone to be shattered even if knocked in the garden, fixing them properly is recommended, especially if you have children and pets in your garden playing around.
Here is a table that will help you get a better idea:
| Material | Acrylic | Glass |
| light-weight | heavy | |
| not as strong | very rigid and sturdy | |
| can be bent | remains flat | |
| portable and versatile | difficult to move | |
| less reflective quality | best reflection quality | |
| shatterproof | can be splintered or shattered |
What Shape and Size is Best for Garden Mirrors?
The shape and size of the garden mirror majorly depend on your needs and requirements. Are you going to use them for decorative purposes or create an illusion of better light and more space in your garden?
If you have a small garden space, you can consider placing a full-length mirror that will make your garden seem more spacious.
Placing it at ground level will help you create an illusion of a doorway to another garden area. And by mounting the same mirror at eye level, you can give your garden a lengthier look.
Instead of picking one large mirror, you can choose various small mirrors. This will help in creating a window-like effect in your garden. These mirrors may even sneak into the other part of the garden, adding an interesting aspect to the space. You can place them in a way that reflects different parts or features of your garden.
Coming to the shapes and patterns of garden mirrors, you can choose from a never-ending list. This also depends on your needs for your garden.
You may want a mirror that goes well or blends in with your existing garden theme. Or you may want a mirror that stands out and grabs everyone’s attention. So, once you know what you want from your mirror, you will make a better choice.
How to Weatherproof Outdoor Mirrors?
While acrylic mirrors are already weather-resistant, you should consider weatherproofing them if you choose non-acrylic mirrors for your garden. This will protect the mirror from rusting and developing a black edge that is quite common with constant exposure to harsh weather conditions like rain, ice, snow, and sleet.
You would need a mirror edge sealer or a water-proof silicone caulk. One can easily find this online or at a hardware store.
You can run a bead of caulk at the spots where water might seep. Or you can cover the whole back and sides with the spray.
This would also prevent the mirror’s edge from blackening, which can damage the mirror and increase its life to a considerable level.
Are Garden Mirrors Useful?
Mirrors can be a great addition to your garden. If used properly, they have the potential to completely transform your space, making it look a lot bigger and brighter.
Once you know what you want from your garden mirrors, this will become a lot easier and help you get maximum benefits.
By placing some garden mirrors, you can add a new dimension, highlight your garden’s best features, and even bring some light to the shaded spots. Not to mention, if placed cleverly, you can even hide or camouflage some unpleasant features of your garden with mirrors.
Although finding the right spot for your mirrors in your garden can be tricky, it is worth it all. And once you have done that, you can create magic in your garden.
