To grow a mandarin tree from seeds, follow these steps for optimal success:

What seeds to plant?

  • Choose seeds from hybrid species of tangerines available in the market, as they germinate more quickly, flower earlier, and produce edible fruit.
  • Select seeds that are plump, firm, and without signs of damage or decay.

Prepare the soil for the tangerine seeds

  • Use potting soil with a neutral pH of 6.5 to 7, or create your own mix using humus, forest soil, and sand.
  • Ensure the soil is well-draining to prevent waterlogging.

Choosing a pot for seeds

  • Select pots with drainage holes to prevent water accumulation.
  • Use containers that are at least 7-9 cm deep to accommodate the growing seedlings.

How to plant tangerine seeds?

  • Plant the seeds immediately after extracting them from the fruit, without drying them out.
  • Plant seeds to a depth of about 4 cm in the soil.
  • If unable to plant immediately, soak the seeds in warm water for a few days or store them in a damp towel until germination begins.

From seed to germination

  • Germination time can vary but typically takes around a month.
  • Maintain soil moisture and ensure a temperature range of 20-25 °C for optimal germination.

How to maintain a mandarin tree?

  • Water: Keep the soil consistently moist but not waterlogged. Water regularly, especially during the growing season, and reduce watering slightly during the dormant period.
  • Light: Provide plenty of bright, indirect light, shading the plant from direct sunlight in summer and providing supplemental lighting in winter.
  • Temperature: Maintain a moderate temperature range of 16-25 °C, avoiding extremes that can stress the plant. Provide winter rest with temperatures around 10-12 °C.
  • Fertilizer: Young plants don’t require fertilization initially but should be transplanted into larger pots as they grow. Older trees benefit from regular fertilization during the growing season using citrus-specific fertilizer or organic alternatives like cow or chicken manure.

By following these guidelines, you can successfully grow a mandarin tree from seeds and enjoy the beauty and flavor of homegrown tangerines.
