LFUTARI 13″ Square Planter Insert
The LFUTARI 13″ square planter insert is designed to fit large flower pots, reducing soil usage and overall pot weight. This makes it easier to move containers while maintaining adequate drainage to support healthy root systems. The insert features enlarged drainage holes that help prevent root suffocation from overwatering. It is best for buyers using 13×13 inch pots or interior displays that require a lighter, soil-saving solution.
Who this is best for: gardeners with heavy, large planters who want easier handling and lower soil costs. Why selected: the combination of soil reduction and improved drainage supports healthier roots without sacrificing structure.
Caution: verify the midpoint width of your pot (not the top) to ensure a proper 13×13 fit, as this insert is designed for a precise interior dimension.
LFUTARI 2 Pack 13″ Square Planter Insert
The LFUTARI 2 Pack mirrors the single insert’s benefits but adds value through multiplicity. Designed for large pots, these inserts cut soil usage and pot weight while maintaining effective drainage for strong root health. Their reusable nature supports ongoing plant cycles, making them a practical option for homeowners with multiple large containers or seasonal displays.
Who this is best for: buyers with several 13×13 pots needing consistent soil-saving inserts. Why selected: two inserts in one package offer cost efficiency and uniform performance across multiple planters.
Caution: confirm pot midpoint measurements before purchase to ensure a precise 13×13 fit across all chosen planters.
OAKENZ Square Planter Box Liner Bag (Large)
The OAKENZ liner bag is a waterproof, heavy-duty insert made to fit square planter boxes up to 18 inches by 18 inches. Its flexible material allows a clean corner fit and reduces soil contact with planter walls, helping retain moisture and support healthier growth. This option suits wooden, concrete, plastic, resin, and metal planters seeking a moisture barrier and easier pot maintenance.
Who this is best for: owners of larger square planters who want a moisture-retentive, soil-sparing liner that adapts to many box styles. Why selected: versatility across materials and its moisture barrier benefits support longer plant life.
Caution: ensure your planter does not exceed 18×18 inches to avoid a loose fit in larger boxes.

The Bloem Ups-A-Daisy insert provides notable soil weight reduction—up to about 50%—and features pre-drilled drainage to optimize water flow for through-watering. Its maintenance-free resin construction resists fading thanks to UV protection, making it a set-and-forget option for both indoor and outdoor use. The 14.75-inch size is suitable for mid-to-large square planters.
Who this is best for: gardeners who want substantial soil and weight reductions with a simple, durable build. Why selected: the combination of drainage management and UV-resistant resin makes it reliable under sun exposure and seasonal use.
Caution: the slightly uncommon 14.75″ size requires matching planters with compatible interior dimensions to ensure a snug fit.
Conderyang 2Pcs 14″ Square Planter Insert
The Conderyang insert comes in a two-pack set of 14 inches and features a bright orange color that can add a decorative pop to any planter. It is designed to significantly reduce soil volume and overall container weight, simplifying movement and rearrangement. The insert includes multiple pre-drilled drainage holes to prevent overwatering and promote better air circulation for healthier root development.
Who this is best for: customers who want an aesthetically distinctive option and practical soil reduction in 14″ pots. Why selected: two-pack convenience plus effective drainage supports robust root systems while lowering handling effort.
Caution: color may stand out in certain décor; ensure the orange shade complements your planter’s design scheme.
Buying Guide
What matters most when choosing square planter inserts?
- Size accuracy: Measure the interior width and depth of your square pot. Inserts must fit snugly in the interior space without forcing or bending.
- Drainage design: Look for pre-drilled drainage holes or breathable materials to prevent root rot and promote healthy growth.
- Weight and soil savings: Plastic inserts that reduce soil volume ease handling, especially for large planters or elevated decks.
- Material durability: UV resistance and weather tolerance extend the life of inserts used outdoors.
- Maintenance: Durable, washable materials that resist fading and can be easily cleaned between plantings.
Which insert type should you choose?
- For frequent movers and patio setups: choose lighter, 13″ or 14″ inserts (like LFUTARI or Bloem) to minimize lift effort.
- For multi-plant displays: consider a two-pack solution to standardize sizing across several planters (LFUTARI 2 Pack, Conderyang 2Pcs).
- For moisture retention: liner bags from OAKENZ help manage soil moisture and reduce direct contact with planter walls.
Maintenance and care considerations
- Rinse inserts after use to remove soil and salts that may degrade plastic over time.
- Check for cracks or warping after extreme temperature changes, especially in outdoor settings.
- Inspect drainage holes to ensure they are not clogged by debris.
