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.

Pruning and caring for calamondin

It isn’t really necessary to prune it.
To rebalance the silhouette of your calamondin, prune lightly after repotting, in spring.

It is advised to repot every 2 years.
Best to do this at the end of winter or in spring after the blooming and fruit formation..
Otherwise, summer is fine, too.
