My Bonsai Juniper Has a Large New Growth

New Growth

• Healthy bonsai trees produce new growth in the spring. If your tree produces a vigorous new shoot or branch that ruins its shape, prune it back with a sharp knife or pruning scissors. If the new growth adds to the aesthetics of your bonsai, pinch out its growing tips once it reaches the desired shape and size. Control the overall shape of your bonsai by regularly pinching out its growing tips between finger and thumb.

Rampant Growth

• Check the underside of your bonsai pot if it continues to throw out large new branches. Sever any roots that have grown through its drainage hole and into its gravel tray or the ground. Juniper trees are not naturally small and will develop into full-size trees if their roots are not restricted. A bonsai with large roots needs to have them pruned back.

Controlling Growth

• Water your bonsai as soon as its soil starts to dry out and do not try to restrict its growth by withholding water. Reduce the amount of fertilizer you provide if your bonsai is producing too much new growth. Normal bonsais should be watered every two weeks with a balanced liquid fertilizer diluted by half.

Root Pruning

• Remove your bonsai from its container and wash off all the soil. Allow the roots to dry and cut them back until the root ball occupies the same volume as the branches. Cut back the most vigorous roots by half. Replant your bonsai using compost mixed with 30 percent sharp sand or a soil formulated for succulents. Place a layer of pea gravel at the bottom of the container to aid drainage.
