Giant planters spanning over two feet wide make a dramatic statement in any garden. Their expansive size allows you to get creative with plantings by combining everything from tall exotic palms to cascading vines.

For maximum visual impact, look for extra large planters modeled after species like conchs, nautilus, and whelks. The spiraled shape adds fluid, naturalistic style.

Using Seashell Planters Outdoors

To get the most out of seashell planters outdoors, follow these tips:

Select a Durable Material

Outdoor seashell planters need to withstand the elements year-round. Look for pieces made from:

  • Fiberglass – Extremely durable and weather-resistant
  • Concrete – Long-lasting and able to handle cold climates
  • Cast stone – A mix of concrete and other materials for durability
  • Resin – Lightweight yet strong against weathering

Avoid cheaper plastic or ceramic pots that can crack and warp outside.

Allow for Proper Drainage

Outdoor planters require drainage holes so excess water can escape. Check that your seashell planter has holes before purchasing. If not, you’ll need to:

  • Add drainage holes yourself with a power drill.
  • Place a layer of gravel at the bottom beneath the soil to improve drainage.
  • Pour away excess water that collects in a drainage saucer.

Trapped water can cause root rot and other problems for your plants.

Handle the Weight

Extra large seashell planters often weigh over 100 pounds when filled with soil and plants. Make sure you choose a permanent spot that is:

  • Accessible for planting and maintenance.
  • On a sturdy, level surface that can handle heavy weight.
  • Has multiple people available to assist in moving if needed.

Wheeled plant stands are great for easily moving heavy pots into place.

Select the Right Size

Take plant dimensions into account when choosing your seashell planter size. Look for a planter that:

  • Accommodates the root ball with extra room.
  • Is proportional in size – don’t overwhelm or underwhelm your plants.
  • Allows enough space as plants grow taller and wider.

Bigger is not always better – an oversized planter can lead to issues with too much damp soil.


Regularly care for outdoor seashell planters by:

  • Rinsing dirt and debris with clean water.
  • Resealing concrete, fiberglass, or resin planters annually.
  • Watching for cracks, chips, fading.
  • Treating any damaged areas promptly to avoid worsening.

Proper maintenance preserves your planter’s beauty and keeps plants healthy.

Styling With Seashell Planters

The right accessories and placement let your seashell planters make the biggest impact. Design tips include:

Pick Colors and Finishes

  • Warm neutral tones like sand, taupe, and ivory that complement natural materials.
  • Glossy finishes that reflect light beautifully.
  • Matte and textured finishes for understated elegance.
  • Distressed finishes with chips and variation for a timeworn look.

Place for Maximum Impact

Position extra large seashell planters as the star in spaces like:

  • An empty patio.
  • The center of a gravel garden.
  • Near walkways as a gorgeous greeter.
  • Surrounded by smaller pots on the porch.

Repeat for Drama

Using identical or coordinating seashell pots together amps up the wow factor. Try:

  • Flanking an entryway.
  • Pairing on each side of steps.
  • Creating a seashell border.

Repeating planters with lush, overflowing plants looks incredibly full and vibrant.

Blend Sizes and Shapes
