Make sure your box has good drainage. If not, drill drain holes along the bottom of the box. Insert a screen cut to the size of the box’s bottom to prevent soil from escaping or clogging the holes.

Mix the soil and add a healthy 3- to 4-inch layer to the bottom of the box. If your box is more shallow, just be sure your soil depth is at least 2½ inches—the bare minimum.

Fill in the box with additional soil until the entire surface is level, and the base of the plants are about 1 inch below the top of the planter. Feel free to gently adjust plants until their bases line up across a smooth soil bed.

Top-dress the soil with polished pebbles for a smooth, modern feel.

THE GIFT THAT KEEPS ON GIVING Many succulents propagate by cuttings--meaning you can break off a leaf or cut a stem just above the next leaf or set of leaves (using sharp scissors, a knife, pruning shears, or your hands), let it callus for a few days in part shade until you see new roots start to form, and plant it in a new location. Or give cuttings to friends to plant in their own window boxes.

Be sweet to your succulents
Steer clear of low-light and water-heavy situations—both surefire ways to kill your succulents. When you notice the first inch of soil has dried, wait a week or two, then water your box. The less sun your plants get, the less water they will need. When you do water, thoroughly drench the soil until water drips into your collection trays below.
 
Avoid temperatures below 40°F. Keep your box next to a sunny window during harsh winter months. A cold draft near a window is okay and often good for plants accustomed to cooler, but not freezing, temperatures.
 
Rotate your box to keep the succulents from leaning to one side.plant with personality
 
• Thanks to the diversity of succulents, you can create a garden bursting with spreading, hanging greenery or keep it nice and tidy like a minimalist sculpture garden.
 
• To achieve pink tips, move your box outside in the summer months.
