48" Window Boxes Are Long On Curb Appeal

To create a visually pleasing flower window box display that will boost your home's curb appeal, you have come to the right source. This section features 37-48" window boxes in a wide variety of styles and designs. For instance, several of our wrought iron flower boxes come with coco coir liners, adding a natural look to your home's exterior. For a more country look, choose aluminum or iron cages and add your own terra cotta or ceramic flower pots. As an alternative, some individuals like to add liners. Our most popular choices include bronze tone, silver tone, copper tone or 100% real copper window boxes for a modern effect.

So Many Window Plant Containers Available

If you've been considering planters for the deck or porch and have chosen a style for the front of your home, why not add some lovely balcony railing planters for a coordinated and cohesive effect. After choosing window plant containers, select either the same or complementary balcony railing planters to complete the curb appeal picture. Specialty hardware for attaching window box planters on railings can be found in the hardware section of this website.

Maximize Watering Practices with Self-Watering Window Boxes

To protect plants from drought or under-watering, self-watering window boxes can save the day, and your plants. Some of the window box planters in our collection can be ordered with a self-watering function. Yet even those planters that don't come with built-in reservoirs can be fitted to be self-watering simply by ordering a reservoir system (elsewhere on our website.) Alternatively, you can select plant amendments such as PlanterWell GrowBrownies to put in in the bottom of your planter box. They hold up to 8 times their weight in water, allowing plant roots to wick moisture through capillary action, when your plants are thirsty. Available in either brick form or as "crumbs", GrowBrownies are convenient to use too.

Optimal Sizing for Window Box Selection

Finally, after you have selected your window box style from our many diverse styles, ensuring you get the best "fit" to improve curb appeal and showcase your home in its best light is important. The general rule of thumb when determining which size you need is to order one at least the length of your window and no more than 4" overhang on either side.
