Selecting Pots
Choosing a pot involves a few practical trade-offs rather than one universally "best" option. Consider the plant's mature size, how often you're willing to water, and where the pot will sit, since all of these affect which pot makes the most sense.
Drainage Holes
A drainage hole allows excess water to escape after watering, which matters more than almost any other single pot feature. Without drainage, water can accumulate at the bottom of a pot, keeping soil consistently wet and increasing the risk of root problems over time. If you have a decorative pot without drainage, using it as an outer cover for a properly drained nursery pot is a practical way to get the look you want without the risk.
Pot Size
Pot size should roughly match the plant's current root system, with some room for growth — not the eventual mature size of the plant. An oversized pot holds more soil and moisture than a young plant's roots can use, which can leave soil wet for longer than is ideal and increase the risk of overwatering. As a plant grows, moving it up to a slightly larger pot in stages is generally more reliable than starting in a pot that's far too large.
Container Materials
| Material | Characteristics | Watering Impact |
|---|---|---|
| Unglazed terracotta | Porous, breathable, relatively heavy | Dries out faster; needs more frequent watering |
| Glazed ceramic | Non-porous, decorative, often heavier | Retains moisture longer than terracotta |
| Plastic | Lightweight, widely available, less breathable | Retains moisture well; easy to overwater if not careful |
| Fabric grow bags | Breathable, lightweight, foldable when not in use | Dries out relatively quickly; supports strong root development |
Balcony Containers
Balcony growing introduces a few extra considerations beyond typical container gardening — wind exposure, weight limits, and often more intense sun than a similar spot at ground level. See the balcony gardening guide for guidance specific to this kind of space.
Hanging Containers
Hanging containers work well for trailing plants and can make use of vertical space that would otherwise go unused. A few practical points: hanging containers tend to dry out faster than similarly sized pots on the ground, partly due to increased air exposure, and it's worth confirming that whatever they're hung from can safely support the weight of the container once it's filled with wet soil, which is considerably heavier than dry soil.
Soil Choices for Containers
A potting mix formulated for containers is generally the right choice, rather than soil dug from a garden bed, which tends to compact and drain poorly in a pot. Some plants — succulents and cacti, for example — benefit from an even faster-draining mix with added ingredients like perlite or coarse sand. See the soil & fertilizer guide for more detail on this.
Watering Differences in Containers
Container plants generally need more frequent attention than plants growing directly in the ground, since there's a limited volume of soil to hold moisture and containers are more exposed to drying influences like sun and wind, especially outdoors. Checking soil moisture directly remains the most reliable approach — see the watering guide for more on how to do this well across different container types.
