Thank you Nigel! I think I know what tree will go in this pot - probably in late summer.

Thank you!

Glad you liked it

Gracias!

Thank you!

Sometimes I put a little piece of wood dowel or when the person I am making the slab for asks, but for my own I generally don't drill drainage per se, I make sure that there is no surface concavity that would pool water and if there is, a simple tie down hole solves the issue. In general I will only drill tie down holes and this is sufficient and I do that at the time of repotting so that the tie down positions are tailored for the root system I am planting.

Thank you!

thanks Chris, I never reapplied sealer yet to any pots but I use 2 different kinds of sealers and only recently (since february) have I started used this one from Behr - a tree in it is quite happy. The other pots are all sealed with a sealer from Interstar.ca and there are trees in them for 2 years already. Depending on the angle I will use the pot I may not need drainage because water will never pool in it but for the other angle, I will need to drill drainage. Since I will have to drill anyhow for tie downs, I will then drill for drainage if necessary - or the drainage provided by the tie down holes may be all that is needed.

That is great to hear Jonathan!

@@rafi_N Say Rafael did you see Rayan Niels pruning a Dawn redwood episode? I need to do mine and do not know where to start. Do you have a link on that video you can pass on to me by chance? Thanks

@@jonathanaristone2468 I don't own any Dawn redwood but here is what I learned from Mirai: Dawn redwood has compound leaves growing in a opposite pattern. When a piece of growth ramifies and the central stem is reddish, you can prune either to keep a staggering pattern or you can prune the tip to stop the continuation of elongation. If you prune a compound leaf without ramification, you will not have adventitious buds develop because it is a weak piece of growth. So those you leave alone and with the pruning of the strong parts to equalize foliage density across the tree and give more light to the weaker areas you will get those to develop. In strong areas you can remove crotch growth as part of the process to generate equal balance of foliage or cut back to existing growth. Any piece of foliage even with ramification but that has a green stem you should leave alone until the stem turns red before pruning. Now is not the time though for styling or wiring and the removal of branches. Let the tree recover the energy spent in flushing and style next spring. Any branches that are still in development you don't touch it. Keep the strength in the weak areas. Here is the link to the Mirai Dawn redwood post-flush harden pruning from this week but you have to be a member to be able to watch: live.bonsaimirai.com/library/video/dawn-redwood-post-flush-harden-prune

@@rafi_N Thanks Rafi much appreciated

@@jonathanaristone2468 my pleasure.

Thank you!

It doesn't really matter. If it is not dry though there is a risk of something breaking as you apply force while spreading the second layer. I wait until it is dry between 6 and 12h.

Hi, most definitely not the same. He uses something that includes epoxy or something similar. I would also love to know what he uses. :)

@@rafi_N thanks Rafi, I notice when Ryan drills into it is doesn’t make partials that look like a cement base. I thought perhaps it was air Crete with epoxy but not sure! I will find out though I promise!

@@paulkendeffy8893 If and when you find out, please share with me!

It will be very expensive to ship to the US. I am pretty sure you can find the Poraver expanded glass beads in the US. The rest is just cement and polymer fibres - easily available. Yes, you can make large slabs. I have one that is ultra thin and nearly 30" long with wire mesh inside.

You'll have to import it from Germany.

I drill them each time at the time of planting to place them at the ideal places for the specific tree.

It is not sold in stores but you can buy directly from the company that produces it called Poraver.

yes it is possible. It is from a company called Poraver.
