A 60-inch self-watering window box, the Fairfield spans wide windows and keeps a reservoir under the soil. Its listing claims an all-season, fade-resistant finish, and it is long enough for a real run of plants without the 6-foot Yorkshire's extra span.
Pros

- Self-watering reservoir noted in the listing
- All-season and fade-resistant claims from the seller
Cons
- Shorter than the 72-inch Yorkshire in this list
- Material and weight not stated by the seller
Good fit if
- Windows or railings around 5 feet wide
- Gardeners who want one long self-watering box
Skip if
- Windows shorter than 4 feet, where a 36- or 48-inch box is easier

The black counterpart of the 4-foot Fairfield, this 48-inch self-watering box matches dark railings and trim. Its listing does not state a material, so it is best for buyers who want the black finish and do not need resin or included brackets.

$68.45 (as of 10/18/2026 12:07 PDT - Details)

Pros

How we chose these
We started with every Mayne planter in the live catalog: 9 listings, from a 24-inch window box to a 6-foot trough. Two entries are the 48-inch Fairfield in white and black; we kept both because the white one names resin and wall-mount brackets while the black one offers the dark finish, and we judge each on its own listing. Every pick is scored on the seller's stated specifications: length in inches, material (resin, polyethylene, or unstated), and whether the listing names a self-watering reservoir or a built-in water reservoir. Prices shown are live and read from each listing; they change with the store. Everything here comes from the published specifications and the manufacturer's descriptions.
What to look for
What a self-watering reservoir does
Most Mayne window boxes in this guide carry a self-watering reservoir, a water-holding compartment below the soil that roots draw from as the topsoil dries. Seven of the nine picks here are labeled self-watering in their listings; the two Cape Cod boxes name a built-in water reservoir instead. If you water on an irregular schedule, choose one of the self-watering picks to cut back on daily checks.
Match the length to your window
Measure the span of the window or railing before buying. A 24-inch Nantucket fits a single narrow window; 36-inch boxes (Fairview or Cape Cod) suit double windows; 48-inch boxes cover standard 4-foot runs; the 60-inch Fairfield spans wide windows; and the 6-foot Yorkshire handles picture windows. Leave a few inches of clearance at each end so brackets sit on solid framing.
Resin or polyethylene
The pool lists two materials. The Fairfield 4-foot is resin, a rigid outdoor plastic; Suncast, a resin planter maker, describes its resin products as built for everyday outdoor life. The Cape Cod 4-foot is polyethylene, a lighter and more flexible plastic. The listings do not state weight or wall thickness, so choose the material you can mount comfortably and that matches the look you want.
Drainage and container size for vegetables
Container crops need drainage: a window box should let water pass through so roots do not sit in standing water, and a reservoir in a self-watering design must still be able to shed overflow. According to the Old Farmer's Almanac, most vegetables need at least 12 inches of soil, and a 5-gallon container is the minimum for a tomato or squash plant. The 24-inch Nantucket is best for shallow-rooted greens; use the longer boxes for fruiting vegetables.
Mounting and placement
Window boxes hang on brackets or sit on railings. The Fairfield 4-foot resin box names wall-mount brackets in its listing; other picks do not, so plan for separate hardware. Place boxes where they get full sun: the Old Farmer's Almanac recommends 6 to 8 hours a day for fruiting vegetables. Keep them near a water source, since containers dry out faster than in-ground beds.
Fade resistance and all-season claims
Several listings describe the finish as fade resistant and all season. Garden planter makers, such as Austram, describe their planters as engineered to endure the elements, and Mayne's listings make similar claims for these boxes. The seller does not quantify a warranty period, so treat the phrase as a durability expectation rather than a guarantee.
Questions
Are all Mayne planters in this guide self-watering?
Seven of the nine picks here are labeled self-watering in their listings. The two Cape Cod boxes differ: each names a built-in water reservoir, and the 3-foot model quotes 6.5 gallons. All nine are designed to hold water near the roots, but the wording differs, so read the listing if the label matters to you.
What size window box do you need?
Measure the window span and pick a box a few inches shorter. A single narrow window takes the 24-inch Nantucket; double windows suit the 36-inch Fairview or Cape Cod; 4-foot runs take the 48-inch Fairfield or Cape Cod; and the 6-foot Yorkshire handles picture windows.
Can you grow tomatoes in a Mayne window box?
Tomatoes need a 5-gallon container at minimum, according to the Old Farmer's Almanac. The long window boxes here hold several gallons of soil, but a window box is shallow, and depth is not stated for most picks. Choose compact or dwarf tomato varieties and the longest box you can mount.
Do Mayne planters resist fading?
Several listings in this guide describe the finish as fade resistant and all season, including the Fairfield and Fairview boxes. That claim comes from the seller; the listings do not give a warranty. If fading worries you, pick black or white, and keep the box out of the most intense afternoon sun.
Can you use these planters indoors?
Mayne markets these as all-season outdoor planters: window boxes hang outside and the tall square stands on patios. Indoor use is not excluded by the listings, but you will need a waterproof tray under the box and a way to handle reservoir overflow, since these units are designed for outdoor drainage.
