How to Grow Endless Supply of Mandarins in Pots

Fill the planting pots with potting soil, leaving some space at the top for the seeds.
Plant the mandarin seeds about 1 inch deep, then lightly cover them with soil.
Water the soil until it is moist but not waterlogged.
Place the pots in a sunny area and keep the soil consistently moist.
Once the seedlings have sprouted, apply fertilizer every 6-8 weeks.
Transplant the seedlings to larger pots as they grow.
With proper care, your mandarin tree should start bearing fruit within 3-4 years.
