Essential Tips for Successful Window Box Gardening

Before selecting your plants, keep these crucial tips in mind for the best results:

• Choose the right window box: Make sure it's deep enough (8-12") for roots to grow and has drainage holes.

Petunias are a classic favorite for window boxes, with big, showy, and continually blooming flowers.

• Filler: Medium-sized, bushy plants (e.g., impatiens, begonias) that fill out the bulk.
