Perfect Growing Conditions
Creating the right environment for Tradescantia spathacea ‘Purple’ is simple. Here’s what it loves most.
Light
- Indoors: Bright, indirect light is ideal. A sunny windowsill with filtered light works beautifully.
- Outdoors: Prefers partial shade to full sun. In hotter climates, some afternoon shade prevents leaf burn.
The more light it receives, the more vibrant the purple coloring becomes.
Soil
- Type: Well-draining soil is key. A mix of regular potting soil with sand or perlite works well.
- pH: Neutral to slightly acidic soils are best.
Avoid heavy, water-retentive soils, as they can lead to root rot.
Watering
- Water when the top inch of soil feels dry.
- Keep soil slightly moist but never soggy.
- Reduce watering during winter when growth slows.
This plant tolerates short dry spells better than constant wetness.
Temperature and Humidity
- Thrives in temperatures between 60–85°F.
- Cannot tolerate frost. Bring indoors if temperatures drop below 50°F.
- Enjoys moderate humidity but adapts to normal household air.
Caring for Tradescantia spathacea ‘Purple’
Once established, this plant is almost effortless to maintain.
Fertilizing
- Feed with a balanced liquid fertilizer every 4–6 weeks during spring and summer.
- Skip feeding in winter when the plant rests.
Pruning
- Remove faded or damaged leaves to encourage fresh growth.
- Trim leggy stems to keep the plant compact and bushy.
Repotting
- Repot every 1–2 years or when the plant outgrows its container.
