DIY Herb Garden: Most herbs love sun and are made for bright kitchens. Line your window sill with small pots, or purchase a long plastic planter made for sills. Or, experiment with various containers, like colanders or antique watering cans.
Plastic Bottles instead of Pea Gravel Pea gravel and pebbles can weigh down window boxes. Empty water bottles are a lightweight option. Place rinsed bottles inside the planter and add soil on top of them. The space between the bottles will allow proper drainage without the extra weight.
