We all know bamboo grows fast, right? And is light, easy to cut, and very strong? So it makes the perfect sustainable garden resource - growing your own timber products each season is now possible once you plant bamboo! But isn't it invasive and just generally a complete no no for the suburban garden? Not when you use a clumping variety of bamboo, like I have planted, which has all the positives of bamboo without the invasive growth habit. In short, bamboo is the perfect short term harvest timber product. Here's how I used last summer's growth in my garden this weekend just gone.

For the first growing season I watered it weekly, and it grew well, having about five or six green canes emerging from the base which were the width of my thumb. They coloured to black over the winter and for the second season the canes were thicker until the fourth summer just gone the canes were 4 to 6 inches diameter and just screaming out to be used for some building project in the backyard.
You may be familiar with the terraced vegetable garden and citrus orchard I have built at Merewether Life, and in preparation for the fast approaching spring I did some tidying up and strengthened the walls holding the terraces. Now I'm not one for too much concrete and bricks around the growing vege patch, so I have used bamboo to build the retaining walls, which are more like 18 inch holds so the soil does not wash down the hill in a storm.

I recommend clumping bamboo to gardener's who aren't afraid of a little mess, as the bamboo after all is just a giant grass so does have some leaf fall that needs to be swept up every now and then (thanks KC). Further, this makes a great easy to compost additive for mulches and once in place it dries and sits light and loose. I use it around established trees and as a base in all my planting holes for some extra organic matter. Another thing about bamboo is it's height, up to ten metres which sounds high but is really handy for a quick growing screen to obscure inquisitive neighbours or to deflect heat from west facing brick walls (our reason). The bamboo loves the heat and will appreciate some extra water across Feb and early March, otherwise it will retire some leaves early to save on transpiration losses (more sweeping, thanks kc!).
This years challenge is to air layer some cuttings from the bamboo as I have so many requests for cuttings and I think it would make a real treat for a Christmas present for all of those who have asked. But that's another post...
