Congrats on choosing blocks for your garden bed. If you're looking for trees, I suggest considering a maple tree. They grow nicely over time, providing shade and privacy. I recently moved to a new house myself, and I'm also exploring plant options. Back in my hometown, we had a reliable tree service that helped us with planting and maintenance. Maybe you can find something similar in your area. I came across this website, https://www.deepdale-trees.co.uk , which might be helpful for you. They offer a variety of trees and services.

Start by spending a portion of your budget on the various dream feature items that are relocatable and can be used in your final design anyway. e.g. Buy the firepit you really want - it can become the focal point of your future garden. Test it outside in your backyard for a few months. Are heaps of mozzies annoying you while you're sitting outside around the firepit? If so, then you'll know that you're going to need a gazebo with flyscreens as well as privacy curtains so you can really enjoy lying outside in your hammock year round. The hammock is another relocatable part of your design. First, lie outside in your backyard on a swag or a rug for a few hours. Is it too windy? Is there road noise? Keep experimenting until you've found the perfect location for the hammock. Then buy an inexpensive hammock and suspend it from a couple of sturdy RL4 poles. If it's working, then this is the place where you should build your future patio, that's going to shelter your hammock. Keep testing inexpensive versions of your other ideas out. Trial tea candles or a string of inexpensive white Christmas lights as garden lighting. Do they create the feel you want or do lights just attract moths or unwanted insects? What about relocatable solar garden lights? Or a portable floodlight from Bunnings? Where's the ideal place for your garden table and chairs? Test it out with inexpensive camping chairs - or chairs you already own for a few months to be sure. Then invest in the perfect outdoor table and chairs. Same with the water feature. Start with a wine barrel with a waterlily or a second hand pond off Gumtree. Can you hear the trickling water in the garden or do other noises crowd it out? Keep in mind big goldfish need deep water and space to swim. To help you in your choice of plants,look around your immediate neighbourhood. What purple, blue and scented plants are thriving in your immediate area? Who has the best garden in your street in your opinion - and why do you think that? Do you always see a particular neighbour passionately working outside in their garden? That's the person you should strike up a conversation with to get advise about suitable plants for your immediate area. Chances are they will not only give you heaps of free advise but they will probably give you plants and cuttings as well. Markets are another source of perennial plants that grow well in the local area. Plant these smaller plants into large plastic pots and garden bags and allow them to grow for a year or so. Consider herbs as filler plants - many are highly scented, can be used in cooking and often have interesting foliage e.g. choc mint, fennel, rosemary etc. After you've been using your backyard for at least a year and you've experienced all of the seasons, then invest in your big ticket items like your gazebo. Buy or build a structure that's truly practical for your local microclimate - incorporate glass, windbreak fencing, shadecloth, mozzie mesh or whatever you need to make your hammock shelter ultra comfortable. Build this structure where you've tested it and know it will work - not where a stranger who designs gardens thinks it should go. Spend the remaining money on the things you know you need and want - the stones, plants, irrigation, a birdbath, etc

Hi, it could be an osthmanthus they have a highly perfumed flower, but on saying that they sometimes don’t flower until the tree is quite old, a native frangipani is evergreen with similar leaves to your trees, these can self seed, your best bet would be to take your samples to your local nursery for identification

Hi all, we moved into our place a few years ago and inherited a beautiful mango tree full of fruit. It has been gradually getting this silvery look down the centre of the leaves and now getting worse to a real dark brown, definitely affecting the underside of the leaves worst, and more the older leaves. Unfortunately I don't really know much about it, and after googling you get a million different answers and my tree could have absolutely anything! We got an arborist out who just said nah it's a big healthy tree, it's fine, just fertilise more. I'm sure it's getting worse and don't want to lose this beautiful tree if I need to treat it or prevent spread, but am at a loss where to look next. Could anyone give me any pointers as to who I could look into or any links that could assist me better? We're in WA so not really tropical, more dry heat. Thanks so much.
