The Flower Window BoxesTM brand Modern Square Outdoor Planter is made from PVC with a matted finish that
looks like wood. All of our PVC planters are considered an upgrade over
vinyl and will NEVER be mistaken for shiny plastic. They can be painted
or left unpainted with the standard white finish.
Outside Dimensions = 22"Long x 22"High x 22"Wide
Made from 5/8 inch thick solid material
reservoir systems can be added as an option to reduce your watering
frequency 3x fold by allowing you to store three times the amount of
normal watering beneath the soil. As the soil dries out it begins to
wick the extra backup water and absorb it keeping the plants from drying
out. Great for those going on vacation or with a busy lifestyle.
This planter is also available with castor wheels for rolling (see
option below). The bottom of the planter is raised 4" during
construction to conceal the wheels.
Our large cube planters come in various sizes including 18x18x18",
22x22x22", and any various tall rectangular lengths from 24" long to 108"
length. We can also custom make our PVC square planters in custom cube
sizes for both residential and commercial, as well as indoor and outdoor applications.

PVC PLANTER INSTRUCTIONS:
Use ANY exterior latex paint of your choosing. There
is no requirement to prime before painting as the composite PVC readily accepts
an exterior latex paint. We recommend Sherwin-Williams Pro Industrial
Multi-Surface Acrylic Exterior Latex Paint in eggshell finish for fastest cure
times and superb adhesion.
Paint brush or paint roller
is easiest to paint your planter while empty. There is no need to prime or sand
your planter. Paint directly on planter with a brush or roller using any exterior grade latex paint. DO NOT PAINT INSIDE OF BOX, YOU WILL
PLANT DIRECTLY INSIDE. If you prefer, you can paint an inch down to
where the dirt line is. Oil based paints and spray paints will not work. It’s
ok to use a professional spray system and spray the latex paint on. Let paint
completely dry before filling with potting mix. Store boxes in covered garage
2-4 days till dry.
1. Avoid painting in
direct sunlight or on a surface that is too warm, or heat blistering can occur.
Do not paint in freezing weather or temperatures below 55 degrees. Paint on
days with 55 degrees and rising temperatures.
2. Remove any water and
dirt on the PVC first. Moisture trapped under the paint can push its way out
and cause moisture blistering/bubbling.
3. DO NOT USE oil-based paint or
spray paints in a can. Make sure that your paint is a 100% acrylic exterior
4. Latex can take 2-4
days to dry. For this reason, avoid exposing to dew, high humidity, moisture,
freezing or rain shortly after you have painted the box. Painting in a damp
basement or similar area can lead to blistering or bubbling of the paint due to
water being trapped inside or under the paint prior to it drying.
5. Paint directly on PVC
with a brush or roller using an exterior latex paint.
6. Do not store outside
to dry!!! Leave in dry garage to dry until ready to install.
Optional - Self-Watering Reservoir
Optional - Rocks, Pebbles or Styrofoam peanuts (lighter material)
Optional - Black Landscape Fabric (tightly woven). Available at most nurseries
or box stores.
Use quality Potting Mix. Potting mix is preferred over potting soil.
Step 1: Install the window box
or place planter in desired location.
Black Landscape Method
Step 2a: Cut a strip of
tightly woven black landscape fabric slightly larger than the inside bottom of
box. Place a layer of landscape fabric first, on the bottom of box, underneath
the reservoir and covering all the drain holes. This will act as a filter to
capture potting mix prior to clean water exiting from drain holes so that
potting mix does not spill through drain holes.
Pea Gravel Method
Step 2b: Place a layer of small
rocks or pebbles. This will act as a filter to capture potting mix prior to
clean water exiting from drain holes so that potting mix does not spill through
Step 3: Place your Flower
Window Box Self-Watering Reservoir inside of box on top of filtration layer
(fabric or gravel). Wicks only need to stick out of the reservoir system about
1.5”. A good potting mix will draw water 6-8” from each wick. NOTE: For boxes
over 12” tall, overtime roots grow deeper towards wicks and encourages deep
Step 4: Add potting mix to
your box for best results. Fill up to 1-2 inches of the top of your box.
Step 5: Proceed by adding
your choice of flowers, plants, herbs or seeds.
6: Each time you water your box: First water and saturate your potting mix.
Then pour water down your downspout if you have a reservoir system filling it.
This will allow you to put 3x as much water in your box so that you water 1/3
as often. As potting mix dries out it will pull water from wicks out of the
Monitor first couple of weeks to see how often you should re-water your box as
well as fill your reservoir system.
