Mailbox with bright flowers

Curb appeal doesn’t start with a brightly painted front door or perfectly trimmed hedges. The first impression of your home’s personality is the often-overlooked mailbox. Giving yours this cheerful makeover will set you back less than $50, but will make a big first impression. In addition to planting a ring of flowers, we upgraded the actual mailbox and numbers, spray painting them to correspond with the fresh array of spring colors on display. You may find your letter carrier lingering as he delivers the bills and bank statements.

Check out the Mailbox Garden discussion on our forums, then print out this Garden Club Project Card to take with you to your local Home Depot store.

Add color with plants

1. Pick out the perfect plants.

Your mailbox will likely be a location that gets full sun, so head to that section of the Garden Center or check in with a Home Depot certified nursery consultant.

2. Prep the site.

Dig out existing turf and break up the soil to allow for new plantings.You can till the removed turf into the soil or place it grass-side down to provide natural compost.

3. Plant the bed.

Place the tallest plants or shrubs in the center of your bed and surround with shorter plants of varying color and texture. Consult the plant tag to determine how to space the plants.

4. Add soil and edging.

After planting, add a layer of garden soil to promote root growth. Add contrast and protect your plants from weeds by surrounding the bed with edging, such as marble chips or color-enhanced mulch.
