Potting-On Bonsai

The word Bonsai means ‘tree in a tray’ in Japanese.

Chinese Elm

Keeping the root environment healthy is  essential when cultivating bonsai trees, and that means re-potting when the roots become overcrowded or the plant is still in the early stages of growth.

When choosing the media you should use the tree species as a guide and use a soil composition which replicates that in which it would grow in its natural habitat.  Generally though a mix of equal parts loam, peat and sand would be fine.  Alternatively, you can buy proprietary bonsai composts which will suit most species.

My bonsai is a Chinese Elm which has been in my family for nearly 20 years (no pressure to keep it healthy!).  It has been a while since I re-potted it last, the roots are in need of trimming and the soil is depleted.  Here I explain the simple process of re-potting it.

Soak the whole rootball until saturated.

Making sure the root zone is wet will lessen the risk of transplant shock

Tease out the old soil from the roots.

Remove as much old compost as possible

Trim any excessively long roots.

Place a layer of fresh compost back in the tray before replacing the tree and gently dibbing in the fresh compost around the roots making sure there are no air pockets.

Adding new compost

Water well with a rose.

The Old Pear Tree

This poor old pear tree is so neglected and in desperate need of renovation but I need to find a ladder tall enough first!  It’s fruiting on current season’s wood so the pears are right at the top, no doubt the birds will love them.  This type of renovation pruning needs to be carried out in the winter so plenty of time to find a ladder.
