Recycling Eucalyptus: taking advantage of resurrection

Eucalyptus regeneration: tips & tricks for potted plants

Gustavo Iglesias Trabado
GIT Forestry Consulting - Consultoría y Servicios de Ingeniería Agroforestal - www.git-forestry.com - EUCALYPTOLOGICS

We have previously seen in EUCALYPTOLOGICS a good number of examples of Eucalyptus regeneration at their natural habitats in Australia, timber plantations overseas and garden designs using these plants. Today we re-visit this topic from an angle that can be useful for those growers having overgrown potted eucalypts. A new outlook for those plants can be achieved taking advantage of Eucalyptus stubborness to survive.

Fig. 3: Overgrown potted Eucalyptus suitable for recycling via coppicing. (Click image to enlarge)


Advantages of Recycling Potted Eucalyptus

• A new outlook can be developed for specimens with poor form, signs of damage in their aerial part or having an aesthetic attractive below average
  
• Can help assess comparative coppice vigour for different species, varieties or provenances, many of which are rare in cultivation
  
• Growth rates can be faster than from seed to seedling since root systems are already formed
• Allows further decisions once re-shooting is ongoing as formation pruning, bonsaification or shape sculpture
• Forces the plant to produce new shoots of juvenile foliage, which can be interesting if this is the main ornamental feature
  
• Keeps a door open to future annual or biannual severe pruning, starting over as the plants gain more size than desired in order to keep them as smaller potted specimens for display or as indoor plants
  

Disadvantages of Recycling Potted Eucalyptus

• More suitable for specimens having already developed a lignotuber, albeit this is not always necessary
• More suitable for fast growing Eucalyptus species, and better if juvenile leaf shapes are an important ornamental feature
  
• Too old potted plants may be rootbound and might require root pruning and transplanting to bigger pots for this technique to yield best results
• In most cases root quality is inferior in the long term compared to potted plants grown directly from seed to seedling and needing no coppicing, especially if these are grown using root air pruning techniques
  
• Coppice timing must match appropriate seasonal conditions: plants need light, warm temperature and abundance of water and nutrients to rebuild... but pruning risks must be minimised
  
• Coppice results are variable from specimen to specimen within the same plant lot, shape homogeneity is difficult to achieve sistematically without intensive observation and frequent interventions
  
• Nutrient availability can be low or exhausted in an old potting mix, making a proper fertilisation/fertirrigation regime necessary

Natural regeneration in Eucalyptus (4): E. gunnii, E. nicholii & E. blakelyi

And yet more images on vegetative regeneration in Eucalyptus, in this case young potted plants experiencing a small coppice trial at nursery. As we had seen by now for planted out forestry species E. delegatensis, E. obliqua, E. globulus and some provenances of E. nitens, for these other forestry/ornamental species as E. blakelyi (Blakely's Red Gum, series Tereticornes), E. nicholii (Narrow Leaved Black Peppermint, section Maidenaria) and E. gunnii (Cider Gum, section Maidenaria too) natural regeneration from both lignotuber and axillary buds is frequent and vigorous.

Totally unrelated, some historic/taxonomic notes on these species:

- E. gunnii was named by W.J. Hooker honouring J.C. Gunn, two remarkable eucalypt botanists at Kew and Tasmania respectively in the late 19th century.
- E. blakelyi was named by J.H. Maiden honouring W.F. Blakely, two of the most prominent eucalypt botanists in the early 20th century and authors respectively of the Critical Revision and A Key to Eucalyptus.
- E. nicholii was named jointly by Maiden & Blakely honouring W.H. Nicholls (?). But if they had lived in the 21st century maybe they would have very seriously pondered if naming it E. nicollei instead!
