We are looking at planting a 20m hedge of hibiscus cottonwood across the back of our block this year. We are in Perth near the coast but will be prepping the soil following fu's instructions.
1 - what spacing should we be planting them? If they are too close will this restrict the height they grow to?
2 - we currently have a couple already on our block, will they shoot roots quickly from cuttings?
3 - when is best to plant them? Will they be fine to plant now or should we wait till autumn, winter or spring? Ideally the sooner we get the hedge in the better.
Thanks
