Photography Tips and Tricks:

Photograph the planter in its natural setting.
Make sure the planter is as clean as possible.
Try taking the picture with and without the flash to see what works best. Sometimes flash from a distance helps fill in the photo but sometimes when it’s too close you will have harsh shadows.
Avoid taking a picture of your planter in the direct sunlight (it will blow out the photo). A cloudy day is always better.
Zoom in so the planter and plants fill the picture but please be sure not to cut off the planter in the photo.
Take a photo from a short distance to “set the scene” or portray an “atmosphere”.
The planter should be showing at least 80% in the photo. Don’t let your plants overtake your photo.
Take the photo mid-season so you’re showing not too little and not too much of the actual plants.
Large photo files are a must so if you have the ability to take a large photo with your phone go for it but if you have a digital camera that might work better.
Good Luck!

For occasional surface cleaning, we have found that the following products work very well along with a quick rinse from your garden hose:

  • Simple Green – A good environmentally friendly cleaner
  • The Works: Basic Bathroom Cleaner with Bleach – Our production facility has been testing a number of regular household cleaners and have found that this one works surprisingly well on our products and is obviously a great value!
  • Mr. Clean Magic Eraser – Great for our White products
  • Armor All – Great to bring out the shine on our black products

For a deeper clean, we recommend the use of a high power pressure washer. As polyethylene is slightly porous, small dirt particles can become trapped over time and a power washer, used up good and close will be able to really blast the dirt away. Don’t worry about damaging the planter when cleaning with the power washer. Our products do not have any type of finish so there is no risk of harming the outside.

It may take some time to remove all of the dirt and stains, but with the pressure washer on the highest setting, you’ll find that the results are fantastic!

Mayne products are designed in Canada and manufactured in the United States.

We carry three products that are an exception to the above. Our Yorkshire Collection, the No-Dig Ground Anchor, and the Adjustable Deck Rail Bracket. They are made from vinyl and stainless steel, respectively. Due to the difference in material, these items are imported.

We do not recommend painting our products. Our products are manufactured from polyethylene, which is an oil based plastic. We have found that paint typically does not adhere to it very well; it tends to peel and flake off over time.

That being said, there is a paint on the market that is called “Fusion for Plastic” made by Krylon, which some of our customers have used with success. Please be advised that painted products cannot be returned and that painting the product will also void the warranty.

Our Yorkshire model window boxes are made of vinyl and can be painted with any paint designed for use on vinyl. Painting our Yorkshire models will not affect their warranty.

When creating any product, the quality of the material makes all the difference. That’s why we only use 100% high-quality polyethylene resin sourced from the United States and Canada.

We only purchase material from industry-leading resin suppliers to ensure our products maintain the highest level of consistency. Unlike other garden products, Mayne products do not require painting, staining, or any other additional preparation.

We’re confident in the quality of our material and back our products with a 15-year residential warranty.

Planters & Window Boxes

The trick to removing your Mayne Window Box from its mounting brackets is to use something flat like a flat head screwdriver to “pry” the bottom of the window box from the brackets. Once you have the window box popped out from the mounting brackets, you should be able to slide the window box out and remove it from the side of your home.

Still have questions? Send us an email to [email protected] and we would be happy to send you further information and photos detailing this process.

The following styles of planter all have a water reservoir underneath the planting area:

  • Mayne Tall Planters that have a removable tray
  • Patio Planters
  • Window Boxes

With the water reservoir, capillary action allows water in the reservoir to soak upward keeping the soil and plant roots moist creating a “self-watering” effect.

Regular watering is required for the first few weeks giving the root system time to develop. Once the roots have grown down into the troughs of the planters, the plants will be able to pull moisture from the reservoir. With this system, you will find the potting mix stays moist longer than traditional planters. To avoid over-saturation an overflow hole allows excess water to drain out.

Although “self-watering” containers still need to be watered, they need to be watered less frequently than your typical planter.

How often you need to water will depend on a number of factors including, climate, sun exposure, rain exposure, etc. As a general rule, we recommend watering once per week once your plants are established. Many will likely find they will need to water less frequently than this. If the potting mix begins feeling dry simply continue to add water until excess begins coming out of the overflow drain hole. This will ensure the potting mix is well soaked and the reservoir completely filled. You will get into a routine with your plants after a couple of weeks.

For our Planters that have the Water Reservoir feature, the reservoir can be filled just by watering your plants as normal. Any excess water that the potting mix is unable to absorb/hold, will filter through the potting mix and fill the reservoir.

You will know that the reservoir is full when you begin to see water coming out of the overflow drain hole (see How do I know the Reservoir is Full?).

Alternatively, you may also wish to drill the optional Fill Porthole to create direct access to the reservoir.

When planting, we recommend using a “Lightweight Filler” to decrease the overall weight of the planter. Larger planters and window boxes can take bags and bags of soil which is not only expensive but can also be very heavy. For window boxes, this puts extra stress on the mounting brackets holding your box up. The weight of the soil is heavy to move, and may also cause issues of the weight compressing and compacting the soil affecting drainage and root growth. To solve these issues try using a lightweight filler to fill the bottom of your planters.

What can be used?

  • Styrofoam packing peanuts (NON-BIODEGRADEABLE) or other broken up Styrofoam packaging
  • Empty Water/pop Bottles with the lids on
  • Pearlite or Vermiculite
  • Lava rock
  • More ideas here http://www.thriftyfun.com/Filler-Ideas-for-Potted-Plants.html#solutions

The basic purpose of the fill/port hole is to give direct access to the reservoir in order to fill it faster or drain it entirely. This is a completely optional feature and if you would prefer to not drill into your planter it will still function normally.

To cover the hole we have included a rubber plug that can be easily removed to fill or drain the planter as needed. The reservoir will still fill without the hole by excess water filtering through the soil.

Once the reservoir of your planter is filled to capacity, water will start seeping out of the overflow drain hole. Always make sure there is a clear passageway out of the drainage hole to ensure water can escape.

This overflow drainage hole is manufactured/pre-drilled in all of our window boxes and Patio Planters.

Our Tall Planters require you to drill your own drainage hole. The hole is not pre-drilled in our tall planters so they can be used indoors if you would like.

Once the water starts seeping out of the overflow drain hole the reservoir is full. Always make sure there is a clear passage way out of the drainage hole to ensure water can escape.

The Overflow drain hole is manufactured/pre-drilled in all of our window boxes and Patio Planters.

Our Tall Planters require you to drill your own drainage hole. The hole is not pre-drilled in our tall planters so you can use it indoors if you would like.

All of our window boxes are molded with the back matching the front so that they can be used as independent planters and be viewed from all sides. The window boxes also have small “feet” on the base of the window box that prevents the overflow drainage from being blocked when used on the ground.

When installing onto vinyl or metal siding:
We recommend using plywood strapping (1”x4” plywood is suitable) in order to add strength and support.

Step1) Attach the board to the siding where you would like your Window Box to sit than

Step 2) Once the holes are pre-drilled, drill the brackets into place.

Step 3) After the brackets are secure slide your new Window Box into place.

When installing your window box to brick or concrete walls:
Masonry screws or anchors are recommended.

Step 1) Pre-drill holes into the brick or concrete where the brackets will be placed.

Step 2) Once the holes are pre-drilled, drill the brackets into place.

Step 3) After securing the brackets, slide your window box into place.


Please note: our molded window boxes (such as the Fairfield, Cape Cod, and Valencia models) do not require any assembly.

All Mayne Tall Patio Planters have a removable tray to plant directly on top of. If you would like to remove the tray, push down firmly on one corner and lift up on the opposite corner.

Don’t be afraid to use as much force as needed to get the tray to pop out of place, the tray will bend and flex around the walls of the planter and this is fine. The material is extremely durable and you will not damage it at all by doing this.

The trays can also be flipped upside down to create a raised platform for a potted plant. Similar to the removal, a little extra force may be needed to drop the tray back into position.


Still have questions? Email us at [email protected] for further details and some photos to further illustrate this process.

When a Planter or Window Box-wall begins to bulge out, it is typically due to a drainage issue. (see How does my planter drain excess water?) Please check the underside of your Planter/Box to ensure that nothing is blocking the drainage hole. If you find that there is a blockage, go ahead and clear the hole using something long and pointy (a coat hanger wire or something to that effect, should do the trick). Water should then be expelled through the drainage hole.

The material Mayne products are made from has an incredible memory, so after the water drains from the planter, it will slowly return to its original form. Leaving the window box or planter out in a warm, sunny area can help to speed up this process!

If this method of clearing the blockage is unsuccessful, the easiest solution to the problem would be to drill another small hole in the backside of the planter/box for extra drainage. This option is also recommended for those who may have their boxes situated in an area that receives a moderate amount of rainfall.

Mayne products are designed to last in all types of weather conditions – they can even be left outside during the winter months. Just be sure that your planters are draining properly and remove as much water from them as possible but tilting them slightly towards the overflow drain hole.

If you do decide to bring them in, here are some Winter Storage tips:

  • Remove all plants, flowers, and soil from the patio planters or window boxes.
  • Remove window boxes from their brackets by angling the bottom portion toward you while pulling them out.
  • For best results, clean your planters and window boxes by spraying them with a high-pressure washer.
  • Remove as much water as possible by turning the planter or window box over and shifting it from side to side. Note: It will be nearly impossible to remove all of the water from the reservoir.
  • Tall planters can be emptied completely by removing the insert tray and dumping the water out.
    Note: If you have difficulty removing the tray, we have some tips and tricks that may help.

Mayne Patio Planters can be stored outdoors or in your garage or shed without worry. Even with some water left in the reservoir, there is no risk of cracking as our double-walled design will allow room for the water to expand when freezing.

Don’t let the cold and snow deter you from using your Mayne planters! Try dressing them up with some greenery or holiday ornaments to add some color to your home and garden during the winter months!

The Yorkshire Window Box is available in 7 sizes from 2 to 8 feet. At Mayne we understand not all windows are the same size and customization may be required for our customers desired look.

Step 1: Dry fit the window box (pre-assembled without any glue). Hold the window box in place and measure the preferred width of the box.

Step 2: Take apart the front, back, and bottom panels. Mark off the desired cut lengths using a marker and a straight edge. (Example: You purchased a 3FT Window box but your window is only 32inches in length- simply cut off 4 inches).

Step 3: Using a fine-toothed saw cut the panels along the line created by the marker. Be sure to use a proper blade that is able to cut plastic.

Step 4: Make sure that all 3 panels have been cut to the exact same length. Once this is confirmed refer to the Yorkshire Window Box instruction sheet for final assembly.

We do not recommend adding casters/wheels to the bottom of our Planters. Each of our Planters has a double-walled design creating our water reservoir feature; the plastic walls are about 1/8” thick and the section directly beneath the floor of the planter is hollow so that it may be filled with water. Drilling holes in the bottom would ruin the water reservoir feature and there would be nothing to drill into to keep the casters in place.

Please note making any structural changes to the Planters would also void the 15-year warranty offered with our products.

A great solution for making your heavy planters mobile would be to create a platform for them to sit on and attaching the casters to the bottom of the platform. A platform can be made from a piece of pressure-treated plywood cut so that it is just slightly smaller than the base of your planter.

Another handy idea would be to add a lightweight Filler which would make your Planter lighter and easier to move without any additional hardware or modifications.

Mail Posts & Lamp Posts

When installing your mailbox to your new Mayne Mail Post, the steps to follow will depend on the type of support arm you have.

Attaching the Mailbox to our Standard Arm: In order to install your Mailbox to the Mayne Post Arm, you will need a mounting board (a pressure treated board cut to the appropriate size to fit into the lip of the bottom of the Mailbox). Most Mailboxes come with a lip on the bottom and it is very important that the mounting board can sit flush inside the mailbox.

Step 1) When the mounting board is cut to size, use wood screws to attach the board to the mailbox arm at a 90-degree angle.

Step 2) Once the board is securely in place attach the mailbox to the board with screws through the holes on each side of the mailbox.

Please note: Mounting board, Mailbox, and mailbox hardware not included


Attaching the Mailbox to the Newspaper holder: In this case, the mounting board is not required.

Step 1) Pre-drill 4 holes with a 3/8″ drill bit through the mailbox and paper holder arm.

Step 2) Using a nut, bolt, and washer combination secure the mailbox to the arm and tighten (2″ Bolts are recommended).

Please note: Mailbox and hardware not included


For full instructions with diagrams, please contact our customer service team at [email protected] and we will be happy to send you a printable copy.

When picking out a mailbox for our mail posts, the physical dimensions of the mailbox are less important than the actual weight of the mailbox.

Newport, Westbrook, or Charleston Mail Posts:

For these models, we recommend a mailbox that is no heavier than 8 lbs. We have found that the following manufacturers offer a number of mailbox options that will work well with these particular posts:

Metal Mailboxes – http://www.gibraltarmailboxes.com/mailboxes.php?ProductSubType=Traditional%20Rural

Plastic Mailboxes – http://postalpromailboxes.com/plastic-mailboxes/

Dover, Signature Plus, Charleston Plus, and Rockport Mail Posts:

For these models, we recommend a mailbox that is no heavier than 12 lbs. We have found that the following manufacturers offer a number of mailbox options that will work well with these particular posts:

Salisbury – http://www.mailboxes.com/departments/residential-mailboxes/post-mounted/rural-mailboxes/

Postal Pro – http://postalpromailboxes.com/product/the-carlton/

Gibraltar – http://www.gibraltarmailboxes.com/mailboxes.php?ProductSubType=Traditional%20Rural&page=1

While there is no single specific mailbox that we recommend for any of our mail posts, as that is a personal preference, the above manufacturers have a wide selection that many of our customers have paired up with our mail posts and the results are fantastic!

Please note: some of these manufacturers do not sell direct to customers, but their products are widely available online, as well as in many major retailers like Lowe’s & Home Depot.

Our Liberty Lamp Post can be paired with our “standard arm” support bracket (can be found on our accessories page), from which an address plaque can be hung. The arm attachment will not work with our Signature Lamp Post as the inset panel within which the arm would sit is a little too narrow.

Our lamp posts are designed as a decorative sleeve to slide over an existing lamp post or can be purchased with the 3” diameter aluminum pipe for a new installation. When installing the bracket on the lamp post, be sure to use screws that are able to tap into the metal pipe that is inside the decorative sleeve (being careful not to hit any wires). It is important that a connection is made with the metal pipe inside so that it can support the weight of the sign.

Please note that this is a custom installation. This arm was not specifically designed for this use and we, therefore, cannot make any guarantees on the performance of this installation.

While this is not something we have tested ourselves, it could certainly be done with the help of a certified electrician and a little modification to the post. The material that the post is made of can be cut fairly easily using a fine tooth saw or regular utility knife to make an opening for the outlet. The base of the post should have enough room to accommodate a standard small outdoor outlet, as this section of the post measures about 9.5” in width and 6.5” in height, and there is roughly 3.5” of space available on each side of the aluminum pipe within the post.

Any questions regarding the mounting or wiring of the outlet should be directed to your local electrician.

Please be advised that once any modifications are made to the lamp post it cannot be returned and the warranty will be voided.
