Hi Heather, did you find something that worked? If not, do you have any pictures of the space you can show us to help us suggest some ideas?

There are a few options to consider. But all plants, especially in Adelaide which is where I come from, need a lot of TLC when first planted. And now is not the time to plant. Wait until late autumn. 1. Grevillea olivaceae Hybrid 'Two Tone' is an upright form of grevillea with interesting greyish foliage. It grows 2 to 4 metres tall x 1.5 to 2 metres wide. This would be the preferred option as it is very tough. 2. Acmena ''Sublime' - a psyllid resistant form of Lily Pilly that will grow 4 to 5 metres tall x 2 metres wide. The smaller hybrid lily pillies don't have the bad root system of the species plants that were commonly grown. And you need to put whatever plant you choose at least 1 metre in from the back fence to allow for width of the plant. You never plant directly on the fenceline. 3. Syzygium australe 'Pinnacle' is another lily pilly that will give you the height - up to 6 metres and grows 2 metres wide. In order to get a plant growing up to 5 metres tall you will need to expect a width of around 2 metres. As a landscape designer, I always aim to hide fences, unless you can afford fancy corten steel screens. Gardens are expensive places. I am constantly reminding people of this. You can then consider covering the whole back area with gravel over a base of road rubble. This is maintenance free other than keeping any weeds from appearing. A tree can be planted into this, using the gravel as a mulch with a seat at the base. This is the most low maintenance garden you can consider for this space - and this will add value to your property if you do it properly, as a low maintenance garden.

As the concrete buildings are expanding day by day, more and more people are realizing the importance of greenery around. As most of the urban homes are shrinking in size, the room for the gardens is becoming scarce.

In the traditional way of gardening, most of the gardeners use the climbing plants like the squashes and the beans. But in the case of the vertical gardens, the concept goes a little further where the gardeners use the horizontal plans in a vertical way. The vertical gardens take less space and they are easy to harvest. They are also easy to maintain as well. Some of the factors that you need for the vertical green walls are- You require enough sunlight If they are placed too high, they are difficult to maintain. Do not make them taller so that you cannot reach. Keep them at a height where you can reach. The support system should be strong enough to hold the structure and everything for longer time. The supporting system should be made in such a way that it holds the moisture in between the garden and the vertical wall of the room. Thus, it can be stated that vertical gardens are one of the most productive gardening systems. Homeowners, who are having less space for gardening, can utilize their vertical walls for growing the plants.
