Bonsai dirt Q & A


A number of years ago I discussed bonsai dirt in an article entitled “Everything about akadama.” (If you have not review it, you can inspect it out below)

I remain to obtain inquiries on the subject so I assumed I would certainly give a couple of updates.

Q. What is baked akadama and also is it helpful for bonsai?

Baked akadama is akadama that has actually been baked at temperature levels of approximately 800 levels Celsius. The akadama comes to be tough, nearly like ceramic stones, at greater temperature levels, which suggests it stands up to damaging down in the pot. It’s not typically made use of for bonsai however it can be a part of bonsai blends– it simply will not do the exact same task as non-baked akadama.

Q. Is heat-treated akadama the like baked akadama?

No. Some brand names of akadama are subjected to temperature levels around 300 levels Celsius in order to eliminate any type of natural substances located in the akadama. If anything to solidify the akadama, warm therapies are done to fulfill import needs and also do bit. Most prominent brand names of akadama are air-dried as opposed to heat-treated.

Q. What are the distinctions in between soft and also tough akadama?

In time, most akadama fragments damage down in the dirt. The solidity or soft qualities of the akadama impacts the price at which the fragments damage down.

Both soft and also tough akadama can be made use of to wonderful impact in the farming of bonsai. The option of one over the various other relies on one’s farming objectives for an offered tree or varieties.

For instance, I may utilize a reduced portion of akadama (and also a greater portion of lava rock or pumice) when the fragments are soft as this is a simple means to keep excellent drain or oygenation.

In regards to the qualitative distinction in between both, soft akadamas fall apart conveniently in between pinched fingers. Tough akadama fragments are harder to damage.

Q. What is the most effective bonsai dirt fragment dimension to utilize for my bonsai?

As a whole, smaller sized fragments are an excellent suitable for smaller sized trees and also bigger fragments are an excellent suitable for bigger trees. Types that like damp settings (like wisteria or coastline redwood) can take advantage of smaller sized fragment dimensions as they give higher water retention. Types that like drier origin settings can take advantage of combines with bigger fragment dimensions.

Q. What is a water drainage layer and also do I require one?

Water drainage or oygenation layers are layers of dirt with reduced porosity (even more air). It prevails technique to boost porosity in the bonsai pot by utilizing bigger dirt fragments and/or fragments that withstand damaging down.

One typical technique is to utilize the exact same dirt elements at the end of the pot as on top of the pot however with bigger fragment dimensions. One more technique is to utilize fragments like pumice that withstand damaging down (and also consider much less!). Both strategies can urge origin development in the reduced area of the pot for varieties that withstand expanding origins in excessively damp settings.

Q. Do all bonsai take advantage of akadama-based dirts?

No! Great deals of dirt blends that do not consist of akadama can be made use of to wonderful impact. If any type of akadama for the advancement of young trees, I’m presently making use of extremely bit. My chojubai (dwarf blooming Japanese quince), as an example, have actually been expanding well in 100% lava rock (also known as scoria or cinder).

I do not recognize of any type of dirt fragment that does what akadama performs in regards to its capacity to launch and also hold launch, water and also hold plant food, and also assistance origin development over long amount of times. That stated, there are fragments with various attributes that can do a wonderful task sustaining tree wellness and also advancement.

Rephrased, I more than happy to utilize akadama options when akadama isn’t readily available, however I value various aspects of these options (see “ What to do when akadama remains in brief supply” for information).

Luckily, akadama stays readily available from a selection of electrical outlets. Dirt has actually gotten on my mind recently as I simply got 2 brand-new deliveries and also have a lot of tough akadama and also tough akadama-based pre-mixes that are readily available for neighborhood pick-up in the San Francisco Bay Location, online from the Bonsai Tonight Online Shop, and also wholesale for orders of 50 bags or even more
