Charlestonians favor window boxes for two very practical reasons.
One, Charleston is a tourist destination, and residents like to dress up for the visitors.
Two, many homes in the historic district don’t have front yards.

Ensure Proper Drainage
Be sure the window boxes have drainage holes.
This setup is essential for houses with wood siding.
Watch The Weight
Ensure the support brackets can hold the box’s weight when attached to the house.
you could significantly reduce weight by filling fiberglass window boxes with lightweight potting mix,not soil.
Potting mix also provides better drainage, something most container plants appreciate.
Use a potting mix that includes perlite to keep things light.
Add Variety to Spice It Up
One simple rule to make window boxes more interesting: variety.
Plant a combination of plants.
Consider Lighting
For a window box in full sun, the options can seem endless.
In a shady yard or north-facing home, you really need to take lighting into consideration when selecting plants.
Ferns and ivy can add softness and texture.
Keep The Box Hydrated
Remember to water.
Plants in window boxes dry out faster than those planted on the ground.
Fertilize every two weeks with a water-soluble fertilizer such as Miracle-Gro.
Or incorporate a granular slow-release fertilizer, such as Dynamite, into the potting mix before planting.
