How to Choose the Right Planter Like a Pro: The Ultimate Buying Guide

Updated: Nov 20

Updated : Nov 20th, 2025


Choosing a planter might seem easy—until you're standing in front of dozens of options in different materials, shapes, and sizes. Should you go with a sleek metal planter? Is terra cotta still a thing? And what about drainage?

If you’re overwhelmed by the choices, you’re not alone. Whether you're an experienced designer or someone simply looking to green up a balcony or office space, picking the right planter matters. The right one doesn’t just hold your plant—it complements your space, fits your lifestyle, and lasts through seasons.

This guide breaks down how to choose the perfect planter—step by step, like a pro.



Start with the Basics: What Do You Actually Need?

Before you fall in love with a specific color or texture, step back and answer a few key questions:

  • Where will the planter go? Indoor, balcony, garden, rooftop?

  • What’s the climate like? Freezing winters? Scorching summers?

  • What kind of plant are you putting in it? Herbs, succulents, shrubs, trees?

  • Do you want to move it often? If yes, heavy materials like concrete might be a no-go.

  • Are you after low maintenance? Some materials require sealing, others don’t.

Being clear on these helps you eliminate 80% of the wrong choices immediately.


Choose the Right Material for Your Environment

The material of the planter isn’t just about looks. It affects durability, drainage, weight, and weather resistance.

Here’s a quick overview:

Material

Best for

Things to Consider

Concrete

Public spaces, windy rooftops, winter climates

Heavy, durable, can double as barriers

Aluminum

Modern design, light handling, UV-resistant zones

Lightweight, sleek, customizable

Corten Steel

Industrial or modern aesthetics, outdoor spaces

Develops patina over time, long-lasting

Fiberglass

Rooftops, balconies, commercial spaces

Lightweight, durable, wide range of finishes

Resin

Indoor/outdoor, color variety

Lightweight, impact-resistant, modern look

Terra Cotta

Mediterranean or rustic gardens

Classic look, porous, can crack in freezing temps

Plastic

Temporary setups, budget-friendly

Lightweight but less durable, can fade over time

Size Matters: Don’t Go Too Big Too Fast

Planters that are too small can choke root systems, while overly large ones can cause root rot due to overwatering.

General rule of thumb: Choose a planter that’s 1 to 2 inches larger in diameter than the nursery pot it came in. For fast-growing plants, go even larger.

Quick Sizing Guide:

  • 6–10” diameter: Herbs, succulents, tabletop plants

  • 12–18”: Medium houseplants, flowering annuals

  • 24” and above: Small trees, shrubs, large grasses

If you're planting something large, consider commercial-grade options like our fiberglass or concrete planters, designed to scale with your plant.


Form Follows Function: Shape Isn’t Just About Looks

The shape of your planter affects both design and plant health.

  • Tall, narrow pots: Good for deep-rooted plants (e.g., palms)

  • Wide, shallow pots: Ideal for herbs, succulents, annuals

  • Square or rectangular: Great for lining pathways, defining zones

  • Tapered bottoms: Offer stability, especially for top-heavy plants

If stability is a concern—say, in windy areas or commercial zones—opt for planters with a broad base or built-in ballast systems.



Match Your Style—but Keep It Timeless

Planters are part of your architecture. Don’t just follow trends—choose timeless design that complements your space.

Here’s how to align design with space:

  • Minimalist or modern: Go with matte black or grey metal planters

  • Industrial: Choose corten steel or brushed stainless finishes

  • Natural or rustic: Terra cotta, resin with earthy textures

  • Elegant formal gardens: Fiberglass or aluminum in symmetrical pairs

Drainage: Hidden, Essential, and Often Ignored

Yes, it’s tempting to use containers without holes—but that’s risky unless you have a drainage layer or liner system in place.

Why drainage matters:

  • Prevents root rot

  • Avoids standing water

  • Keeps soil healthy and aerated

Pro Tip:

If you’re placing planters indoors or on surfaces sensitive to water damage, use liners or double-walled planters with built-in reservoirs.

Don’t Forget About Color Harmony

Planters are design elements—they should complement your plants and your architecture.

  • Neutral tones (grey, charcoal, beige): timeless and versatile

  • Earth tones: blend into gardens and natural settings

  • Bold tones: create focal points, especially in modern urban layouts

  • Glossy white or black: sleek, contemporary look

If using multiple planters in one area, stick to one color family or a maximum of two contrasting shades.


Final Thoughts: Start Small, Think Long-Term

It’s tempting to go all-in with big planters or exotic materials, but if you're just getting started:

  • Start small, test what works in your space

  • Upgrade gradually as your confidence and plants grow

  • Think long-term—cheap plastic may fade in a season, while metal or concrete will last years


FAQ – Choosing the Right Planter


1. What is the best material for outdoor planters?

The best material depends on your climate and design needs. Concrete and corten steel are ideal for windy or public spaces due to their weight and durability. Aluminum and fiberglass are great for rooftops or terraces because they’re lightweight and weather-resistant. Resin is a good all-rounder for both indoor and outdoor use.


2. How do I choose the right size planter for my plant?

As a rule of thumb, choose a planter 1–2 inches wider than your plant’s current pot. For large plants or trees, ensure the planter is at least twice the diameter of the root ball. Undersized pots restrict growth, while oversized ones can retain too much moisture.


3. Do planters need drainage holes?

Yes—proper drainage is essential for most plants to prevent root rot. If you’re using a pot without holes, use a drainage layer (rocks, sand, or charcoal) and consider a liner with holes to allow water to escape.


4. Can I use plastic pots for permanent planting?

Plastic pots are affordable and lightweight, but they may degrade over time with UV exposure. For long-term durability, especially outdoors, consider fiberglass, metal, or resin planters, which offer better weather resistance and design versatility.


5. What’s the difference between indoor and outdoor planters?

Outdoor planters are built to withstand rain, sun, and temperature fluctuations. They often include UV protection, frost resistance, and heavier materials for stability. Indoor planters prioritize aesthetics and are usually lighter, with more decorative finishes and water-safe materials.
