Planting and repotting calamondin

Planting potted calamondin

It is recommended to plant calamondin in a blend of soil mix eventually enriched with fertilizer.

  • The pot must absolutely be holed at the bottom to avoid having the roots stagnate in water.

An ideal solution is to pour in a layer of gravel, clay pebbles or rocks to ensure that excess water drains well to the bottom.
Make this layer about 1 to 2 inches (3 to 4 cm) thick.

Anticipate re-potting in a pot that is slightly larger than the previous every 2 or 3 years on average.

Planting calamondin directly in the ground

It can only grow directly in the ground in Mediterranean-type climates or tropical climates.

In which case, mix soil mix into your garden soil and ensure that you soil drains well.
If it doesn’t drain well, dig a hole that is slightly deeper, and layer gravel, rocks, sand or clay pebbles along the bottom.
