Planters Buying Guide: Garden, Patio & Balcony Picks for 2026
, 9 min reading time
Planters are one of the easiest ways to add structure and greenery to a garden, patio, or balcony. Whether you want neat lines along a driveway, a few statement pots on a terrace, or a sturdy planter that doubles as a design feature, the right choice affects both the look and how well your plants thrive. Not all planters perform the same: materials, size, drainage, and placement all make a difference. Polyester planters, aluminium planters, and corten steel planters each have their own strengths. In this guide, you’ll learn who planters are best for, when to choose which type, what to look for before buying, and which options from Doika’s collection match different outdoor setups.
What are planters?
Planters are containers designed for planting flowers, ornamental plants, grasses, herbs, or small shrubs. They’re used as an alternative to planting directly in the ground and can also complement existing beds. Outdoor planters are typically built with drainage and made from weather-resistant materials such as polyester, aluminium, or corten steel. Because they’re flexible and easy to position, planters work well for patios, balconies, gardens, roof terraces, and commercial outdoor areas.
Who are planters suitable for?
- Anyone who wants a flexible layout for a garden, patio, or balcony
- People with limited ground planting space, such as on roof terraces
- Those who like clean, modern looks or more natural finishes in outdoor pots
- Anyone combining greenery with structure and design
- Professional spaces such as entrances, offices, and hospitality settings
When should you choose planters?
Planters are ideal when you want more control over placement, styling, and maintenance. They’re especially useful when planting in the ground isn’t possible or isn’t the look you want. Planters also help create sightlines, boundaries, and visual “zones” outdoors. Another benefit is flexibility: you can refresh seasonal planting without major changes to the space.
What to look for when buying planters
Placement: indoor or outdoor
Start with where the planter will live. Outdoor planters should handle rain, frost, and UV exposure, while remaining stable in wind-prone spots. For balconies and terraces, stability is key; for roof terraces, lightweight materials such as polyester or aluminium are often preferred. For indoor use, a watertight finish (or a suitable liner) matters most.
Material and durability
Material shapes both lifespan and appearance. Polyester planters are lightweight, crisp-looking, and colour-stable. Aluminium planters are corrosion-resistant and low-maintenance. Corten steel planters develop a distinctive protective patina that adds warmth and character. Each option balances practical performance with a specific visual style.
Drainage and water management
Good drainage is essential for healthy roots. Drain holes, overflow solutions, and integrated watering features help prevent waterlogging and root rot. For outdoor planters exposed to rainfall, well-designed water flow is one of the most important factors for long-term success.
Size and proportion
The right size depends on the available space and the plants you want to grow. Large planters can support shrubs or small trees, while compact pots are perfect for flowers, herbs, and ornamental grasses. Aim for balanced proportions between the container, the plant, and the surrounding area—and make sure there’s enough room for roots to develop.
