Met the curator of Arboriculture yesterday at the RGB to talk about the Separation Tree. I am writing an article for Vasili's Good Gardening Magazine, of which I am a contributor. I love people like Dan they are so on the ball. He explained what they have been doing to help the tree which was ringbark in 2010. They have had experts from all around Australia and are monitoring it daily, weekly, monthly and every year they climb it to have a closer look.
Dan, explained how the physiological functions work, - testing me on my biology and remembering how it all works and explained that the moisture is going up the tree from the roots as it is still alive but they don't know if the roots are receiving the carbohydrates they need from the leaves and the photosynthesis process. He showed me some of the cambion is still alive (the brown/red bits in the picture) and they are monitoring the soil moisture which is showing the tree is taking up moisture.
Long term prognosis is good but they don't really know. Trees can take years to show they are declining.
I also learnt how to read bark, yes, read the cells going up the bark from a particular root. If you notice on a lot of trees, the bark swirls up the trunk and that is showing you how the nutrients and moisture are being taken up capilllary action.
Fascinating. I had noticed the swirling bark, especially on gum trees, but never really thought what it was saying.
Well, the weather is crazy. It is summer and I am sitting here with a shirt and the heater on!. We are definitely in a La Nina cycle. It also snowed on some of our mountains..... It is summer. It was my first day back at work yesterday and what a day I choose. I rolled up to the garden I look after and it was pelting down. And of course I forgot my beret. If I can keep my hair dry, I can cope working in the rain.
I actually did quite a bit because it stopped raining and for a moment I had taken my shirt off and was quite hot. This weather is mucking up my sowing of pea and bean seeds. I am writing another ebook on growing peas and beans and I sowed some seeds so I could take photos of the seedlings. Well you aren't meant to water the seeds until they germinate, so the seeds don't rot. Well that arn't happening. They have been watered by god quite a bit.
I am off to work today and I am planting some canna lilies and a couple of echinaceas. I hope my client like them, I got a bit carried away and bought more than I planned tooo. Impulse purchasing I think that is called.
