Trimmed roots after washing
Repotting season for the majority of tree species is at an end and here are a few examples of some of the bonsai trees that have been repotted this year showing the variation in root type plus root development on each tree.
Example of repot of a Japanese Black Pine (Pinus thunbergii)
-
- Repot of Japanese Black Pine
-
- Close up of mycorrhizae fungi
-
- Query over whether mycorrhizae fungi takes over the root function when it becomes this advanced
-
- Roots solid in pot and contained within dense mat of mycorrhizae fungi
Example of repot of two Cork Bark Elms (Ulmus parvifolia var Corticosa)
-
- Repotting a Cork bark chinese Elm after leaving a year in between repotting
-
- Still in need of root development to improve nebari
-
- Repotting a Cork bark chinese Elm annually, roots not quite filled the pot
-
- Roots developing well but still need some work
Example of repot of Swamp Cypress (Taxodium distitchum)
-
- Swamp cypress after removing from pot and root development vigorous
-
- Swamp cypress roots after removing the soil and good fibrous roots now starting to form
Example of a repot of two Japanese Snowbell trees (Styrax japonica)
-
- Roots have filled the pot so in need of a repot
-
- Repotting of Styrax after a year in between repotting
-
- Trimmed roots after washing
-
- Roots have filled the pot so in need of a repot
-
- Repotting of Styrax after a year in between repotting
-
- Good example of live fibrous roots on a Styrax
Example of a repot of an English Oak (Quercus robur)
-
- Newly acquired Oak in need of a repot
-
- On examination waterlogged root plate with rotten roots
-
- Unsuitable soil conditions for good root development
-
- Reason why health of tree was in decline and limited top growth
-
- Remaining live roots following the initial repot
-
- Tree reduced down to suit the quantity of remaining roots
Example of a repot of a Stewartia (Stewartia pseudocamellia)
-
- 3rd repot of Stewartia and good fibrous root plate had developed
-
- Up close view of functioning fibrous roots as a pad
Example of a repot of a Kiyohime Maple (Acer palmatum ‘Kiyohime’)
-
- Recent new purchase of a Kiyohime Maple and initial repot
-
- Dense but heavily congested roots with anaerobic conditions at bottom of pot
-
- Slow process to free up the roots before pruning them
Example of a repot of Maidenhair trees (Ginkgo biloba)
-
- 3rd repot of Shohin Ginkgo (2012) and good fibrous root plate
-
- Healthy roots on underside and good root tips
-
- 4th repot of Shohin Ginkgo (2014
-
- 2nd repot of Ginkgo and fibrous root pad remains in good health
-
- Up close view of Ginkgo roots
-
- Good root pad but will need to control the root development underneath to avoid it standing too high in pot
-
- 3rd repot of large Ginkgo
-
- Experiment in development the nebari on a young Ginkgo
Example of a repot of a Taiwan Fig (Ficus retusa)
-
- 2nd repot of Ficus and good level of root development starting to occur
-
- Still need to remove some of the larger roots but staged approach on each repot.
Example of a repot of Common Hawthorn (Crataegus monogyny)
-
- Recently acquired tree and 1st repot to find waterlogged conditions within pot
-
- Girdling roots within pot and majority of live roots around the pot edge within the lip of the pot
-
- !st repot of newly acquired Hawthorn
-
- Compacted root plate but good quantity of roots still viable but root work now required to address nebari
Example of a repot of a Korean Hornbeam (Carpinus turczaninowii)
-
- Limited root pad so root development needed
-
- First repot of Korean Hornbeam after purchase
Example of a repot of an Akebia quinata ‘Shirobana’
Second repot of an Akebia from nursery stock
