Pots for Trees - Large Garden Tree Planters
Think big and plant for the future.
Square & Cube Tree Planters
For a single specimen tree or large palm, cube planters give the depth and root volume mature trees need without a trough’s length. The Cube 600 suits most trees, while our largest, the Cube 1000 and low square 1000, handles even advanced specimens and large palms — its grand scale makes it a genuine focal point in its own right.
Florence Light Concrete
$99.00 – $329.00
Alaska Off White
$99.00 – $329.00
Florence Low Square
$749.00 – $1095.00
Manhattan Cube
$219 – $1495.00
Large Round Tree Pots
Round planters suit a single specimen tree or palm where a softer, more organic silhouette fits the setting better than a hard-edged trough or cube. Their flowing lines create an undeniable focal point — ideal for stepping up from a typical terracotta pot as a tree matures and outgrows it.
Florence Low Round
$495.00 – $995.00
Milano Low Round
$749.00 – $895.00
Manhattan Round
$295.00 – $995.00
Florence Tall Round
$329.00 – $995.00
Rectangle Trough Pots for Trees
Rectangular trough planters are ideal for lining hedges or espalier fruit trees along a boundary, fence, or driveway. Their length gives multiple small trees or shrubs a shared root run, making them a cost-effective way to green a long stretch in one hit — the large Trough 1200 and 1500 are our most popular sizes for hedges and small trees.

Warranty?
Built for Mature Root Systems
Pots for trees carry a different kind of stress than any other planting — a growing root system doesn’t just add weight, it actively pushes outward against the container walls for years. When you invest in a large pot for tree planting, replacing a cracked one after the roots have taken hold isn’t a simple fix. That is why every tree planter we ship includes a standard 3-year warranty, extendable to 5 years at checkout.
What Our Warranty Covers:
- Manufacturing Quality: Guaranteed zero material defects, warping, or surface chips upon delivery.
- Structural Integrity: Engineered not to crack or bow as root systems establish and expand over years of growth.
- Weather Resistance: High-performance finishes built to withstand years of harsh sun and heavy rain.
What Is Not Covered:
- Natural Aging: Minor surface fading or hairline weathering over long-term outdoor exposure.
- Trapped Moisture: Damage from leaving protective wrap on for more than 7 days post-delivery.
- Unsupported Base: Custom alterations, including external feet that do not provide full base support.
- Non-Standard Use: Modifying tree pots into ponds or water features.
For Builders & Specifiers: If you are specifying large garden pots for trees for major commercial projects, the 5-year extended warranty (available at checkout) offers essential long-term protection.

Will My Tree Grow in a Planter?
Yes, many trees can thrive in planters, offering greenery to patios, balconies, and small gardens. However, success depends on several factors.
Choosing the right tree and planter is crucial. Opt for dwarf or slow-growing varieties suitable for containers, such as Japanese maples, olive trees, citrus trees, or certain conifers. The planter should be at least twice the size of the root ball, with adequate drainage holes to prevent water-logging. Larger planters also help regulate soil temperature, protecting roots from heat.
Proper care is essential. Container-grown trees dry out faster than those in the ground, requiring more frequent watering. Use a well-draining potting mix, not garden soil, and provide regular fertilisation. Depending on the tree and your location, you might need to offer some protection from intense midday sun.
Be mindful of long-term growth. Trees in planters will eventually become root-bound, limiting their growth. Plan for this growth by using a larger container or consider root pruning to maintain a manageable size. While container trees may not reach their full in-ground potential, many can flourish for years with attentive care, adding beauty to your landscape design.
Will a Planter Be Able To Handle The Vigorous Root Growth Of a Tree ?
Sigma Planters come with a standard 3-year warranty which can be extended to 5 years. This includes using for Trees
A standard planter, especially one that is too small, will likely not be able to handle the long-term root growth of most trees. Here’s why and what you need to consider:
The Nature of Tree Roots: Tree roots naturally grow outwards and downwards in search of water and nutrients. Confined to a planter, they will eventually:
Circle the inside of the pot (root-bound): This restricts nutrient and water uptake, potentially strangling the tree.
Become densely packed: Leaving little room for soil, air, and water movement, leading to decline.
Exert significant pressure on the planter walls: Potentially cracking or deforming it over time, especially terracotta or thinner plastic.
What kind of tree are you planning to grow? Fast-growing trees with extensive root systems will become root-bound much quicker than dwarf or slow-growing varieties.
Here’s what you need to do to give your tree the best chance:
Choose a large planter from the start: Opt for a container that is significantly larger than the tree’s current root ball – ideally at least twice the width and depth.
Larger planters provide more space for initial root growth and delay the onset of root-bound conditions. Consider extra-large planters made from durable materials like thick plastic, fiberglass, or even concrete for long-term use with larger trees.
Consider the mature size of the tree: Even dwarf varieties will grow over time. Research the mature root spread of your chosen tree to estimate the long-term planter size you might need or if it’s truly suitable for container life.
Be prepared to repot: As the tree grows, you will likely need to repot it into a larger container every 2-3 years. This provides fresh soil and more room for the expanding roots.
Learn about root pruning: For trees that will remain in containers long-term, root pruning is a vital technique. Done during the dormant season, it involves carefully trimming back some of the circling and congested roots to encourage new, healthier growth and maintain a manageable root mass within the pot.
Ensure excellent drainage: Regardless of size, the planter must have adequate drainage holes. Waterlogged soil is a major issue for container trees in Indonesia’s humid climate and can lead to root rot.
