Dear reader, if you are after detailed instructions on how to successfully propagate Gracilis bamboo from cuttings, this is the link you are after: How to successfully propagate Gracilis bamboo from cuttings as I have managed to grow new Gracilis from cuttings after numerous trials. The instructions in this page were not that good and the rate of success was none.
Or you may like to read the entire dickhead neighbour story and ongoing saga at: this new site dedicated to stupid neighbours.
I have finally managed to successfully propagate my very own Bambusa Textilis var. Gracilis! I obtained some culms from a friend and I now have some leaves that have started to bud and very tiny root systems.
It is only fair that I share my findings, but I have to give a lot of credit to Shawn Gilbert who was absolutely instrumental in providing the key points to a successful propagation.
I have currently got a 40% success rate – but this was my first attempt using Shawn’s technique and I have to confirm it works! I am still a little unsure about the exact science as this bamboo has proven to be a difficult plant to propagate. I should also say I didn’t use root hormone (I was too busy cutting the bamboo like mad)
Here are the important points to note:
- When you first cut the culms, put them in a bucket full of some type of richgrow liquid formula. I used “Seasol” diluted in water and soaked the culms for 2 to 3 hours (it is a seaweed fertiliser rich in nitrogen – grass loves nitrogen)
- You must use old culms, the older the better
- Try to find culms with a diameter larger than 1″
- I found culms with large buttons at the nodes had a better success rate than nodes with no buttons (this is for the 2 node cuttings)
- Water the culms every day (ensure that you fill the culm with water) for the first month and a half
- Pick the right time… I planted my culms in the middle of May (Southern Hemisphere = winter)
I have searched the internet for bamboo propagation via culm cuttings and identified two types of cuts that can be used. One cut has 2 nodes, and the other cut only has 1 node and all of the branches coming out of the node have been cut back – all except for the main one (as per Shawn’s website).
It took 2 weeks for the first leaves to appear, but at the 1 month mark, tiny branches were popping out of the buttons at the nodes .
I also noticed the culms that stayed green after the 1.5 month mark would be successful as they had leaves pop out soon after.
We are now getting to the 2 month mark and I pulled one of the culms out to see if it had roots. The photos below show a thin, long and stringy roots.
I am going to leave the culms in the pots a couple of months longer and wait for spring to swing by.
Update: 19th May 2016 – these cuttings all dried and died after months of watering.
But this page: How to successfully propagate Gracilis bamboo from cuttings has instructions that actually worked!
