- Low maintenance
An affordable, big-capacity 20-inch resin patio planter with a simple self-watering disk, ideal for filling a patio with large plants without ceramic's weight; its 11-gallon volume holds a small tree, and the UV-protected resin resists fading. Manage expectations: the disk is a basic reservoir, the thin walls look cheap, and it can blow over in wind.
Pros
- 11-gallon volume holds a small tree, shrub or a full mixed patio arrangement
- Lightweight resin plus UV protection resists fading and is easy to move when empty
- Sealed base with knock-out holes works indoors, then converts to drained outdoor use
Cons
- The self-watering disk is a small basic reservoir, not a true sub-irrigation system like pricier planters
- Thin resin walls feel and look less premium than ceramic or stone
- Being lightweight, it can blow over in wind when tall plants aren't yet rooted

Frequently Asked Questions
- How big a plant fits an 11-gallon planter?
- A small tree, a shrub or a full mixed patio arrangement — 21.5 in top diameter by 17 in tall. That is genuinely large for a resin pot at this price.
- Can this planter be used indoors?
- Yes. The base is sealed with knock-out holes, so it works indoors as-is and converts to drained outdoor use by punching them out. That flexibility is a real advantage over a pre-drilled pot.
- How good is the self-watering feature?
- Modest. The disk is a small basic reservoir, not a true sub-irrigation system like pricier planters, so it extends time between waterings rather than eliminating them.
