Axcoix Adjustable Plant Risers 2-Pack, 12–21" Telescoping Plastic Inserts — Moisture-Resistant Support for Tall Pots

These Axcoix adjustable plastic planter inserts lift and support tall indoor or outdoor pots from 12 to 21 inches, creating a stable, moisture-resistant base without adding soil or stones.

Give tall planters a lightweight, durable foundation with this two-pack of telescoping plant risers from Axcoix. Each kit includes adjustable poles, three differently sized support boards, and screws so you can configure the insert to fit tapered, square, or round pots. Built from weather-resistant plastic, the risers prevent direct contact between the pot and ground moisture while keeping plants easy to move, rearrange, and display.

How do these risers fit different tall pots?

The system uses three detachable support boards (6", 8", 10") that can be combined to match the inside diameter at the pot base and top. The telescoping pole adjusts in height so the same insert works across a wide range of planter shapes and depths.

• Includes two sets of 6", 8", and 10" support boards for flexible base-top matching
• Telescopic poles expand from 12" to 21" to suit pot heights
• Compatible with tapered, round, and square tall pots for seasonal plant swaps

Will these withstand outdoor use and moisture?

Yes — the Axcoix inserts are made from moisture-resistant plastic that won’t rot, rust, or deform like wood or metal alternatives. They resist aging and are suitable for year-round outdoor exposure in most climates.

• Waterproof material prevents moisture absorption and warping
• UV- and age-resistant construction for longer outdoor life
• Rust-proof design unlike metal inserts or hardware

How easy is installation and seasonal maintenance?

Installation is straightforward: connect the telescopic pole to the chosen support boards and set the height inside the pot. The lightweight components make moving pots simple and eliminate the need to use heavy filler materials like stones or soil.

• Fast assembly: two telescoping poles, six support boards, and screws included
• Remove or reconfigure quickly for repotting and seasonal plant changes
• Reduces lifting weight compared with filled-base solutions

How much load and stability can I expect?

Designed as a support platform, the insert stabilizes tall planters by creating an even base and redistributing weight across the boards. While not a replacement for structural pot stands, it improves balance and prevents pots from sitting in pooled water.

• Six-board layout spreads the load across the pot bottom
• Anchoring screws included to secure components for steadier support
• Ideal for reducing direct ground contact and improving drainage clearance

Who this is for: Gardeners and plant lovers who use tall planters indoors or on patios and want an easy, durable way to raise and stabilize pots without adding heavy filler. The Axcoix two-pack is particularly useful for apartment dwellers, urban gardeners, or anyone who rotates seasonal plants and needs a reusable, weatherproof insert that adapts to multiple pot sizes.
