Preparation (Pre-Planting Treatment)

  • Soak in room-temperature water for 2–3 hours before planting. 

Sowing Instructions

  • Best Planting Time: Spring to early summer (or indoors anytime).

  • Planting Depth:1–2 inches (2.5–5 cm) deep with the pointed side up.

  • Spacing:3–5 inches (7–12 cm) apart for proper growth.

  • Soil: Well-draining soil rich in organic matter, such as a mix of potting soil, sand, and perlite.

  • Light Requirement:

    • Indoors: Bright indirect sunlight.

    • Outdoors: Partial shade to full sun.

  • Watering: Water lightly after planting and keep soil slightly moist but not soggy. Overwatering can cause rot.

  • Temperature: Best growth occurs at 60–75°F (15–24°C). 

Aftercare & Growth

  • Germination: Sprouts appear within 2–4 weeks.

  • Watering Routine: Keep soil evenly moist but allow it to dry slightly between waterings.

  • Fertilization: Use a balanced liquid fertilizer every 4–6 weeks during the growing season.

  • Dormancy: In fall/winter, Oxalis may go dormant. Reduce watering and allow the foliage to die back before new growth in spring.

  • Indoor Growing: Can be grown as a houseplant year-round with proper light.

With proper care, Oxalis triangularis will reward you with beautiful purple leaves and delicate pink flowers throughout the growing season! ??
