Post 184 Pot 102 Revisited

In January this year I posted a story about some new pots made at the time. Pot 102 was one of those; a largish compound pot with an overlay glazing. In Post 140 I described the glazing process and result and suggested that this one would be a keeper. We that has been true for some time and I've quite enjoyed being a collector and seeing it on my shelves, happy for it to be there observed by not employed, a reminder of if not inspiration for what might be possible.
It is a pot that needed the right tree and I didn't nave one that made the match.

A friend wanted a pot for a group of three ficus, Queensland small leaf figs and so brought the tree over for a consult and design review. The first thought was a long low oval. The group was growing in a rectangular pot and the trees have lots of aerials taking up a lot of the surface area - a large and rectangular 'footprint'. That rectangular shape at ground level made any thought of oval impractical as the pot would have to be too large to accommodate the rectangular footprint.
 

This is exactly the circumstance that I have designed my compound shaped pots for as well as the bowed wall rectangular pots. Both just soften and lighten up the composition a little and work well with a tree with a large footprint.
With the movement of the trees to the right the best position for the group in a pot was to the left of centre. I'd done a couple of photoshop constructs to help make a decision on the size of a new commissioned pot and in discussing the shape suggested we lift it out and sit in in Pot 102 for size and shape evaluation.

Well as soon as it went in there we both kind of knew it wasn't coming out. Size and colour and texture all worked well with the trees.
So it's not a keeper any more or at least not for me. It has a better home now in the hands of a dedicated young guy with a long bonsai future ahead of him and matched with a group of trees that over time will develop into an even more impressive display than they do now.

Post 183 Tanuki No 4 update

In June ( Post 155 ) I posted an update on this tanuki which I got started in October 2013 ( Post 126 ).

In spring I repotted the tree in a bonsai pot with plenty of room. Summer is with us now and the tree has a head of steam up and growing vigorously. It is time to give it a first shaping and little trim, especially to keep the top under control. Here are front and back pictures before the trim, or actually just after I started and thought about taking some shots.

As you can see I had left a number of branches on the tree simply to thicken up the trunk and ensure it was secure within the channel in the ceramic tanuki. I've taken a couple of these off this time and left one or two on that are still likely to come off later.

The trim will no doubt encourage some back budding and multiple leaders to emerge. The plan is to grow it on, get some extension in a couple of the lower branches and fill out the profile more. Then in spring next year put it in a more appropriate pot and it should be ready for display.

Post 182 Zeolite

Finding the right inorganic components for a good bonsai growing medium is challenging. Size range is critical as is the absence of very fine material. The physical nature of the particles is important too. Sharp surfaces make for much better root development too and with that comes trunk flare. It is possible to buy all sorts of crushed or decomposed rock products but to get them ready for use demands a lot of sieving and washing; hard work and what do you do with the 30% of the material you don't want.

Diatomite is a product sold as an absorbent because of its porosity and as such it is processed and screened to a sizing that is good for bonsai use. It is also readily available in small bags. Diatomite is a mined product but is the remains of marine organisms and is totally a silica material and can be quite soft.

Another mineral product that has wide use as an absorbent and filtrate (filter bed material) is zeolite. It is a hard volcanic rock, typically alumino silicate like the rest of the crust and is also very porous like diatomite. The interesting thing about zeolite is that it is cationically active forming weak bonds with positive nutrient ions like ammonium, potassium, magnesium, calcium and various metals that are useful as trace elements. So zeolite can act as a reservoir of these essential nutrients and TEs for the plant to access over time, as well as the water that it can store in the minute pores in the rock.

I searched out a supplier for Castle Mountain Zeolite this week and managed to get my hands on some of their product. It is sold as Booster Crystals!

 This one is screened to 1 to 3 mm in size and has almost no fines at all. While 2 to 4.5mm would be ideal, as it will be very useful. The rock is crushed so it is very sharp and will be a very valuable additive to my bonsai medium. I can easily see this taking up a 20% position in my mix.
