Perfect Planter Boxes to Line Your Patio and Fence

Long planter boxes come in various sizes and materials, such as wood, metal, or composite. They can be mounted on walls, fences, or windowsills, or placed directly on the ground. The key to their appeal lies in their length, which allows for the creation of continuous, eye-catching displays of flowers.

Design Ideas for Long Planter Boxes

Monochromatic Magic

Create a striking, cohesive look by choosing flowers in a single color palette. This approach works particularly well with long planter boxes, as it allows for a continuous, eye-catching display. For example, opt for a range of shades of purple with lavender, heather, and violet petunias, or go for a bold statement with fiery red calibrachoa and marigolds.

Mix and Match

For a more eclectic look, mix and match different flower types, colors, and textures. Start with a base of trailing flowers, such as lobelia or bacopa, and intersperse taller flowers like petunias or fuchsias throughout the planter box. Add some greenery with ivy or sweet potato vine to tie the whole look together.

Seasonal Transitions

Make the most of your long planter box by changing up the flowers with the seasons. In spring, plant cool-weather loving flowers like pansies and violas. As the weather warms up, transition to heat-loving flowers like petunias and marigolds. In fall, switch to cool-season annuals like snapdragons and dianthus, and in winter, opt for evergreens or winter-blooming flowers like violas and primroses.

Watch - How to Turn Your Ugly Foundation Wall Into a Stunning Garden Feature Struggling with that awkward, dead space along the side of your house where nothing seems to grow? We took a bare concrete foundation wall and turned it into a vibrant flower bed in just one weekend. Not only does it hide the stained concrete, but the added pea gravel makes the whole area look clean and intentional. Here is how you can recreate this look at your own home. The Build Process Start by clearing the canvas. Remove any dandelions, weeds, or patchy grass growing near the wall to ensure a clean start. Next, construct a simple four-sided rectangular frame using rot-resistant lumber like Cedar or Redwood. This specific box is two boards high, which is tall enough to cover the lower concrete without touching the house siding. Once the frame is built, place it on the ground. Use a level to make sure it sits straight, even if the ground slopes slightly. Fill the box with a mix of high-quality raised bed soil and compost. To finish the professional look, lay down landscape fabric around the box and cover the muddy path with clean pea gravel. The Planting Strategy To achieve the lush look shown in the final photo, use the thriller, filler, and spiller method. Place taller plants like Ornamental Grasses and Purple Coneflowers in the back to create height and hide the wall. Fill the middle section with colorful blooms like Red Geraniums, Yellow Marigolds, and Purple Petunias. Finally, plant trailing greenery like Creeping Jenny along the front edge. This will spill over the wood and soften the hard lines of the planter. Protecting Your Home If you try this project, it is critical to protect your house siding. Never pile soil directly against the siding as it can invite termites and cause rot. Keep the soil level below the siding line or ensure the back of your planter box has a barrier protecting the house structure. Drainage and Location Since this is an open-bottom raised bed, water will naturally drain into the ground. If you decide to build a closed-bottom box, make sure you drill plenty of drainage holes so you do not drown your plants. Also, be sure to check how much sun the wall gets. The plants in this example love full sun, but if your side yard is shady, you should swap them for Hostas or Ferns. The Finishing Touch The pea gravel surrounding the planter serves two purposes. Aesthetically, it creates a clean contrast against the wood. Functionally, it prevents rain from splashing mud up onto your beautiful new wood planter during storms, keeping your garden looking fresh longer. | Facebook

Maximize your space by creating a vertical garden in your long planter box. Start with a base of trailing flowers, and intersperse upright flowers like petunias or fuchsias throughout. As the flowers grow, they'll cascade over the sides of the planter box, creating a lush, hanging garden effect.

Caring for Your Long Planter Box Flowers

To keep your long planter box flowers looking their best, follow these care tips:

Sunlight	Water	Fertilizer
Most flowers need at least 6 hours of sunlight per day. Adjust watering accordingly if your planter box is in full sun or partial shade.	Water your flowers regularly, ensuring the soil stays consistently moist but not waterlogged. Adjust watering frequency based on weather conditions and plant type.	Feed your flowers with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season to promote healthy growth and blooming.

Additionally, deadhead spent blooms regularly to encourage new flower growth, and keep an eye out for pests and diseases, treating any issues promptly to maintain the health and beauty of your long planter box flowers.

With these long planter box flower ideas, you're well on your way to creating a stunning outdoor space that will be the envy of the neighborhood. So get planting, and enjoy the beauty of nature right outside your door!
