I agree with Fiona about the Ficus - they have shocking root systems and should never be used near pools, houses etc. The width of your retaining wall from the photo looks really narrow, so you are going to have trouble growing most things in there; even the Pittosporums will eventually cause structural damage to the walls. The width of any garden bed should be ideally 1.5 metres at least for proper root establishment. This seems to be hard for most people to understand, but the bigger the plant, the wider the root system. So either widen the retaining wall or you will need to keep the plant lower. The pears mentioned also will never work. 5 years is the testing time of a good garden. When first planted they can look great, but they often break down as they grow. The Ficus and Pears' root systems will keep on expanding after the 5 year period with the Ficus having surface roots that cause massive damage to paving, concrete etc. Google it! And I have seen first hand the damage done by another Landscaper's work, based on inexperience. Get professional advice if in doubt - it is worth it if you get a good one. Alison

Here's what we did to cover a metal fence that surrounded us. We had an ugly (but brand new) Stratco metal fence that borders the rear house, plus down two sides of the house. Everyday that I looked out onto this metal fence from the kitchen window (with the view of the neighbours over the top of this fence) it became more unappealing, the more we dreamt of a vertical garden instead, but we knew that would take time or a lot of expense, and I couldn't wait that long for that fence view to disappear from view. The solution was some wicker fence cladding, we bought it in 1.8m high by 3 metre rolls from Bunnings (big hardware chain in Australia for those OS) for $30 per roll, it came in a variety of sizes, but we needed that to cover our metal fences. You can do this with a brushwood fence, or to create a barrier from the heat of fence to your plants, you can even clad your fence in what my husband calls "blue-board", it's a thin fibreboard, cheap to buy, in almost any size, it can handle any harsh outdoors, & you can render over it in, paint over or colour the render in any colour you like - a light sand or cream colour will look nicer against any green living vertical garden you choose to put in. My husband made a wooden treated-pine frame around each metal fence panel, and screwed the wicker fence covering to it, with a washer so it held on the uneven twigs that formed the wicker cladding. My husband did such a good job of this, we had a small tornado come through our suburb, winds up to 200km/hr -4 of our closest neighbours lost significant parts of their tiled rooves, but all we lost was one of the stratco metal fence panels, but not the twig fence screwed to the frame my husband made! It helped we were nestled with neighbours in rear & front strata subdivided blocks, houses beside & behind us.. but that wicker twig fence covering & the frame did survive our tornado. Here's what we did on the ground - You can see it a little in the photo's above; as ground cover (with some stone you can get delivered or they often loan you a trailer when you buy a load or 2) we had a couple of cubic metres of ord river stone delivered (mixed sizes) brought it out the back by wheelbarrow, laid it over some weed mat on the ground, creating like a dry river bed effect beside the decked paths down the sides that connect the front and back decks. On the far wall behind the cubby and the slow growing variety of bamboo, we planted several cutting of a friends Ivy that was like a green waterfall over her boundry fence. Within a year, with mains watering (on a timer with misted sprinklers for 5mins once a day that does all our potplants and the side & rear gardens too) we had our own green waterfall, we cut it back when it's long green tendrils start growing along the gound towards the house. A fantastic effect that is very hardy, and cost us nothing! We don't have the wicker fence surround down that side of the house as we don't see the ugly metal fence at all now. In the hottest parts of our summer (up to 46-47C degrees), a few of the ivy's leaves get burnt around the edges, but it's easy just to cut these off. We planted a smaller leaf, much slower growing ivy (on the right in the photos) in the ground on the back fence beside the wicker fence surround, and put up some wire horizontal lines for the ivy to grow along. The 2 bottom photo's are taken 1 year apart so you can see how much it's grown. If you put vines in pots, you will limit (or control) their ability to cover your fence. We cut holes in the weed mat, and planted about 4 native violet ground cover plants. The effect is quite beautiful now, in the heat of summer, the native violet wilts when it's thirsty, but always comes back when it's watered and after summer. We've also put several plants in pots along the fence line to create our garden "oasis" out beside the back deck and down the side (creating garden view from each of the bedroom windows as well as from the kitchen window out the back). We cut some lattice & this blocks out the view of the rear neighbours completely, plus with shadecloth backing on the lattice, it also protects the cafe blinds that surround our back patio from sun damage in summer when they are rolled up in summer. So whatever you plant along the fence, you'll need to create a narrow garden bed in the ground for it to grow well from (we bordered our garden beds along the side fence with narrow 25mm wide limestone blocks or perhaps with railway sleepers or you can buy coated tin garden bed border), most plants or creepers will thrive if they room to spread their roots, even if the fence is hot. There is a small leafed creeper (planted in ground), that sticks to the vertical surface, It has completely covered our stone pillars out the front garden, next to our front gate that looks fantastic - Can't recall what it's called though?? It's taken about 5 years to cover the pillar, but we only planted one (wish we'd bought more now, I've looked but can't find any more of it). We put 3 mid sized chinese jasmin's down the side (behind where the first photo was taken), in narrow in-ground garden beds down the other side of the house. It took a couple of years for these to take off and spread out along the fence line (length of our house), but in the beginning of spring this year they were all in bloom and it created a very fragrant as well as visually appealling cover over and through the wicker fence. The horizontal wire helped so we could wind the jasmin along it as it grew for the best coverage. I wouldn't use those barrels as planters for any vines or creepers, just create a narrow garden bed along the fence line (& beef up the soil quality with sheep or other organic fertilizer,) and even some soil wetter or water crytsals thar will hold the water amongst the roots for up to 3 months, helping any young plants make it out of their infancy so they live and thrive. The water crystals do expand into a gel once they absorb water, so make sure they are well mixed into the soil and buried below the surface around the plants roots for their best effect. The barrels would look better painted, with as mldesign0401 suggested, those strappy leafed plants like the Strelizia's (or birds of paradise), or a tree fern in a shady spot. My hubby also put a variety of herb seedlings into one of those half barrels, put some castors on the bottom of the barrel, as a gift for his Mum, and this way she can move her herb garden about, into the sun as it moves from season to season, in & out of the rain, etc, and she loves it!! Don't forget that a good part of the enjoyment of a garden is watching it grow over time, so beware of mass planting and consider what you plant and how much water and sunlight it gets from season to season. Some of the best advice we had, was have a look at what is thriving around your neighbourhood, ask your friends or neighbours for cuttings, don't be afraid to move plants around if they don't like the first spot you put them in, or if they don't look quite right in that spot. We were also quite ruthless with the plants we bought, chopped several into halves and quarters through the potbound roots (the native violet ground cover, the water-plants, several others), before putting them in the ground, so we spent far less that way. Cutting or chopping through the roots with a knife or shovel, cleanly instead of tearing them apart seems to traumatise the plants far less from my experience. We have an Orange Trumpet vine that does very well here in Perth in WA, but as it can handle WA's heat and still thrive, it might be good idea for someone else out there in Houzz reader land.. ,,although, it does take up a lot of real estate when it's completely covered a fence, it needs room or regular haircuts once established. Looks very impressive in bloom though! We have Wisteria along our front wall, we have trained it along the front boundary fences, it's tendrils of new growth need regular haircuts, but even though it prefers horizontal trellis's or an arbour, over a few years, we have succeeded in taming it onto vertical green fencelines. In spring, when the flowers drape like grapes on a vines, it's just gorgeous, even when it's just the green living walls, it's so much nicer to have living walls and to be surrounded in vertical garden (& that's why for me the fences that usually contain us, transform the space to make us feel different about the spaces that surround or contain us). Using lighting will create a different mood & effect after dark, spot lights or those bollard lights at ground level, and if you lay the wiring (or solar if it gets enough sun) when you're making the garden beds, putting in the plants at the same time, you'll be glad you did later on once everything has started to take off. Or you buy enough fairy lights to do the length of the fence line if you have outside power close by or can hide an extension cord somwhere. I love the sharing ideas and the stories side of this site, I need some help with a structure for shading our front deck by the pool; our West Oz summer sun is scorching- I'm sure the houzz community will have some ideas & photo's that will help us...

Breaking up the great solid block of colour a little bit helps to hide it. Next is the choice of what to plant. I'm leaning towards: ficus pumila, climbing fig, which can be pruned to hug the fence tightly, Himalyan blue bamboo, (but might sprout on other side of fence as well, so should have a 60cm deep root guard or be planted in pots) or waterhousia floribunda, weeping lilypilly, which can be pruned to a narrow, non-climbable hedge but 30cm might be about as narrow as possible. I'm just a bit scared the bamboo will move into the neighbours yard too...You also have to be careful to not plant anything with massive roots that could eventually crack your pool, and it has to be tough enough to cope with a bit of chlorine... Then, put in a dip line so you don't have to water such a narrow spot. Good luck, and let us know what you decide.

A nice invasive running bamboo would be the ticket to isolation. Where are you worried about it invading - your neighbor? When it invades your gravel areas, you cut out the running root, big deal. If you built a wall, you would have to maintain that, would you not? I am renting a house that is less than ten feet(3 m) from the highway right-of-way, but about another 20'(about 6 m) from the actual roadway, which is about 5' (150cm) above my first floor. As the road curves, it passes both first and second floor bathroom fulll-size windows, yeh. Bamboo to the rescue! We are saved by the lovely self-sustaining bamboo. No fertilizing, no watering, just an occasional clipping of its toenails, each spring. It doesn't soften the sound of the Harley's though. To keep the bamboo from crawling out of its crib, install a galvanized or aluminum edging that goes down 6-12'(15-30 cm) to contain these babies from escape. And let the neighbor go back to Dungeons & Dragons or Sesame Street for their entertainment.
