1. Allow your trees to grow a lot and maintain good health before you work them. DO NOT constantly cut them back. Do not cut back or work trees, or cut roots on trees that are not bushy and healthy.
I think this is a hard one for all beginners. I know with me, the first thing I think about when I get a plant home is how can I turn this into a bonsai, and then I proceed to take out my pruning tools and start cutting. Then after I look at it and think, hmmm I should've probably left that on...

2. Only water trees when they start to get somewhat dryish. Do not have a watering routine that is the same every day. You need to check each tree to see whether it needs rewatering. If you have been watering correctly, then you can afford to overwater in preparation of a hot and windy day, or with a water sprinkler when you are on holidays. Overall, do not have a mix that is constantly sitting in wet conditions. Very few trees like to be in constant water.
Guilty again. Only today was I thinking to myself, I think I'm watering too much, the soil is still damp and I'm thinking about watering it again because I don't want them to die. Not realising that actually I'm probably over watering.

3. Wiring isn't neccesary. Its expensive, tiresome, and can be detrimental on the branching if you allow it to stay on too long. You can get beautiful movement from clip-and-grow (just cutting back the new growth hard each year to influence the tree as to how you want it to grow) and you can use anchoring to move heavy branches if you want them repositioned.
Not guilty of this one. I'm terrible at wiring. I should practice on all the trunks that I've chopped off and thrown away. I think as a beginner you just want to get proficient. It comes from a good place but you're right, we probably aren't even doing it at the right time half the time. We just get a new tree and want to do things.

4. You don't need to remove a massive amount of root when you first do rootwork on a purchase. Just focus on separating the roots, and making sure the roots aren't a tangled mess. If you keep the root removal to a minimum, and leave large root removals till a year from then, it will be more beneficial to the health of the tree going forward.
You're killing me here.

I get a pot home and immediately take it out of the nursery pot, and cut off half the root base. I was listening to the
Bonsai Stuff podcast today and he was saying he buys a tree and then will just make sure that it is healthy before he does anything. Doesn't repot it, doesn't root prune, just observes the tree. I need to get better at that.

5. Defoliation should not be part of a routine procedure. I feel it should only be used to promote backing-budding or in some ways, for leaf reduction on advanced material. But it severely affects the health of the tree, as it now needs to send out an entire flush of new growth. If the entire new flush is then attacked by pests, the health declines rapidly as a result of needing another entire flush of growth. If the tree is healthy, this may not be a problem, but you can badly affect a tree from doing this if the tree isn't in great health or used to doing this. Also, the timing of doing this can be disastrous with natives if its done prior to winter before the new growth has had time to harden off.
I don't know enough about defoliation to even know when the right time of year is to do it. I feel like it isn't something beginners need to worry about but maybe I'm wrong there.

6. Get full sun. Make it happen. Most trees love a days sun. You can always build shade for trees, but its too hard to try and 'find more sun'.
Interesting that you would say that, I seem to always be worried that the maple leaves are going to get burnt.

7. Use slow-release fertilizer. That way you usually have time to see if something has gone wrong in your application.
8. Routinely check for pests and caterpillars and borers, particularly on material that is overgrown. They can quickly decimate a large branch if left unchecked.
I feel like I'm good with the checking for pests and the like, but I do need to improve on my fertilizer knowledge. When and how much. I've been looking into the teabag method, again listening to the
Bonsai Stuff podcast got me thinking about it.

9. Style. Style your trees to however you love them. Traditional bonsai or natural is all a preference. But don't immediately remove branches until you've spent a long, long, long time contemplating whether it would be more beautiful to leave the branches on, and make it look more interesting over time.
But the most significant thing with style is to make your decisions early. Once the branches harden off, it can become impossible to move them later on.
It is difficult keeping up with all the different styles and the rules of those styles, I like the idea of being able to design a tree that I like, rather than what all the rules say you should do.

10. When buying new material....If nursery material is loose in the pot, it might be best to avoid this as its either just been potted, or it may have root issues. When you buy nursery material, check the root spread by putting your finger deep into the mix. If you can't get your finger into the mix because its too compact, then avoid it.
Make sure the material has a lot of branching down low to work with and gives you a lot of options. Don't buy a tree simply because its a species you wanted to grow. Choose material that is suited for bonsai. Too many times I've purchased material simply because it was a species I wanted, when I had found a much more beautiful tree in the same species later on and then discarded my earlier purchase. But I find it hard to follow this rule, as I still purchase skinny sticks if its a really desired species that I've wanted for many years.
I think we've all been guilty of buying a tree because it's a species we want to grow, and overlooking all the issues the tree has. I think part of it, at least for me, is the idea that it doesn't matter because I'm just learning so I might as well get any tree and learn the basics.

11. If you haven't got space between your trees, you have too many. They need space for optimum health and sun exposure.
I definitely have space but I get what you are saying. It goes back to the health of the tree. If we want good bonsai, it has to be healthy.
Thanks very much for posting! It made me think a lot.
