The sizes ekka mentioned is about the same as down here, yet totally different climate, interesting.....
Pruning wise its a hard one. We do a lot of Weight Reduction Pruning of major lateral branches on Eucs and in most cases it can be done well if done right. Eucs structure & form amongst its many species varies greatly though, and the citriodora is i'd say the most difficult of all to achieve this on without the problems ekka mentioned. THe species tends to develop very over-extended laterals with small diameter/length ratio in maturity and often have failures in such branches due to the resultant leverage/end weight.
If you have suitable secondary branches closer in to shorten back to then you can make a difference but have to accept the secondary branches as not really been reduced in risk of failure themselves, but the major scaffolds have been.
Other Eucs, such as nicholii lend themselves quite well to Crown or Weight Reduction Pruning. |
