Is Birch A Good Tree For Bonsai?

The birch is a well know pioneer tree that is spread throughout the northern hemisphere, especially in temperate areas. 

There are a number of variants and you can find a lot of these being used for bonsai and they can actually be very impressive trees.

Is Birch A Good Species for Bonsai?       

Overall, birch can be very good for bonsai. It is not perfect and they do have a few down falls, but it has enough positives that it is a good tree to us.

Being pioneer trees they grow extremely easily from seed so there is an almost never ending supply of young material if you live near a full size birch.

They also grow very quickly and once they get some age they can have really excellent bark. They be used for small trees, but work much better as slight larger bonsai trees.

They almost sound like the perfect tree, but unfortunately they can be fussy and randomly allow branches to die back, which is not exactly ideal for bonsai. They are quite short lived and probably average around 60 years, which is of course still plenty of time to enjoy them, but for a tree that is short, although maybe with good bonsai care this can be extended.

Is Birch Foliage Good For Bonsai?

The birch has a nice triangle shape leaf, with jagged edges. I think they look good and they work fine for bonsai.

On a full size tree they are still relatively small, but this can be reduced to a better suited size for bonsai through pruning.  The internode length is also pretty good. You can find some shoots have long straight sections, but if you are pruning for ramification, you can get the internodes to be quite compact and close together.

Is A Birchs Growth Rate Good For Bonsai?

Birch grows very fast, especially when young. You can really see why they are a pioneer species when you see the speed that their seedlings grow at. This means you can quickly get a trunk to thicken, especially if the tree is grown in the ground.   

However, this rapid growth seems to be its curse. For some reason they will drop branches through the growing season. Usually on full size trees this may be small branches that are not really important to the trees, but when you are growing them in a pot as bonsai, that small branch could have been an important part of the structure that you have built.

I have not really had this problem myself yet as my birch are still fairly young, but I am expecting it and it will just mean that I may need to be flexible with the general style or look of the tree. I think if you are prepared for this to happen, it’s less annoying.

Response To Pruning

Birch does respond well to pruning. Where you prune will produce new shoots, which is exactly what you need from a bonsai. However, you need to make sure you balance the vigour in the tree. It can be very easy for one branch to take all the energy and shoot off, which is not what you want.

You should also not defoliate birch, as this will seriously mess up the vigour and you will find some areas do not grow back, while other areas go crazy with growth. This can really ruin your tree, so do not do it.

Back Budding

Birch will also back bud very easily. You may find a few back buds popping out all over the place after you prune. It is very common for them to try and send new shoots from the trunk, especially from around the base and at the junctions where branches meet the trunk.

This is quite annoying and you will just need to keep removing them as they are not useful for bonsai.

Ramification

You can build ramification on a birch very easily. The tight internodes and smaller leaves really help with this and the growth will get finer and finer as you develop the tree. This is exactly what you want when growing a bonsai and this is why you can get some excellent examples of birch used as bonsai.

Is A Birchs Styling Ability Good For Bonsai?

Birch can be easily styled into anything you want, but as they area deciduous trees you should stick with styles that will work best with these types of trees. They work very well as informal uprights and I have actually seen quite a lot of nice birch forests.

Wiring

You can easily wire birch, but you will need to watch out for the wire cutting in. The bark is thin and they are fast growers which is never a good combination. They can grow quite upwards, so some wire may help move things down and open some areas out.

Is A Birchs Fall Colours Good For Bonsai?

In autumn, the birch can put on a good show. The leaves can turn a yellow colour and if you have a well developed tree it can look amazing, especially if you have a tree with white bark. The contrast of colours looks beautiful.

While the autumn colours are not really the reason we grow bonsai, they are a very nice bonus which the birch certainly offers.  

Is A Birchs Winter Silhouette Good For Bonsai?

Once the leaves are gone you will get a good look at the silhouette of the tree and you will be able to enjoy the branch structure and fine ramification.

If you tree is still in development then this is a great time to study your tree and see what needs worked on.

Is A Birchs Bark Good For Bonsai?

The bark is one of the reasons birch is grown as bonsai. It is thin, but full of wonderful texture and interest. The bark is almost paper like and will often split causing very cool look fissures up and down the trunk. This can also hide wounds very well as they can be camouflaged in the texture of the bark. 

A number of varieties actually develop white bark, which can be incredible on a bonsai. A tree needs to get slightly older to look this way, so if you see a white bark birch bonsai it’s usually well developed and a true delight to see.

Deadwood Opportunities

Deadwood is not going to work on a birch. It is more likely something the tree will try and do, by dropping branches randomly. If there any dead branches, you should just remove them.

However, if you have a very thick trunk, some carved hollows can look very impressive along with the craggly peeling paper like bark. This can add a lot of interest to your bonsai.

Are Birch Roots Good For Bonsai?

Birch roots are fairly average. They are just pretty much your standard deciduous tree type roots, which is fine and they work well as bonsai.

I have treated mine like any other deciduous and not had any problems. Just wait until the buds are about to open and you shouldn’t have any trouble.

I have pruned mine quite hard but I’ve certainly not gone extreme, but I have worked them a lot. I have found they are pretty good at growing a lot of fine roots. This meant I could remove any large thick roots and still had a decent amount of fine roots left, so although my pruning may have looked drastic, it wasn’t really.

Is Birch Easy To Care For As Bonsai?

Over all birch are easy to care for. They do not need any special treatment and they can survive the winters just fine. They can get a little thirsty during the growing season, but that is not exactly too hard to deal with.

Conclusion

Birch can be good trees to use for bonsai. You will probably find a lot of people are a bit bitter about them, which is usually from them dropping branches after having developed them for a number of years.

This is fair enough; I do think this would be extremely frustrating. However, if you are prepared for this to happen and ready to accept it, then birch can make an excellent bonsai and you should get one.

If you are a little more rick adverse and don’t fancy dealing with the nightmare of dieback, then I would maybe just admire other peoples birches from a distance.
