Assembly and Installation

Assemble your PVC window box according to the manufacturer's instructions. Most kits come with pre-cut pieces that simply snap or screw together. Once assembled, apply a bead of silicone caulk along the interior seams to ensure waterproofing.

Position the window box beneath or alongside your window, using a level to ensure it's even and secure. Mark the screw holes, then drill pilot holes and attach the box to the wall using screws. Allow the caulk to cure for at least 24 hours before adding soil and plants.

Plant Selection

Choose plants that thrive in the amount of sunlight your window box receives. Consider factors such as height, spread, and growth habit to ensure your plants don't outgrow their space. Opt for plants with similar watering needs to simplify care.

Watering and Fertilizing

Water your window box plants regularly, allowing the top inch or two of soil to dry out between waterings. This encourages strong root growth and prevents root rot. Fertilize your plants every few months with a balanced, water-soluble fertilizer to promote healthy growth.
