Summer Lammas growth

Ive been enjoying a few more days away from work - a well timed gap between projects as I am able to water more often during this spell of hot weather we are having. The weather seems to have kicked off an unusual spurt of growth in some species - specifically the Beeches and Oaks.

I have written before about the Lammas growth - but this year it is very pronounced. I’m guessing that the nice weather has helped the trees to achieved their energy targets for the next winter and they have surplus so they spend it on new growth.

These Lammas leaves in the second flush seem to have come out very quickly and aren’t as nicely formed as the spring leaves. The Beech leaves are a strange colour and the Oak leaves can be slightly deformed having fewer lobes and unusual veins in the leaves.


My small first generation Beech which I potted for fun is coming along really nicely. It is by far the most vigorous of the current generation of Beeches I have. Almost every branch tip is giving growth. I’m nibbling away at the apex buds to keep its apical dominance at bay. These seems to be leading to the lower branches getting some growth as well.

On larger pot grown beeches I’ve nibbled back everything on the crowns to keep them in check. They will grow very thick branches up top if allowed - which leads to an ugly knob forming and no taper. The plan is to allow unrestricted growth on the side branches - especially the lower ones - to allow a good taper for form. Wild Beeches don’t have a great deal of taper but it will look nice - and nice even side branches are easy on the eyes.

In theory I am interrupting the apical mechanism by nibbling off these apex shoots which generate the Auxins hormone which is inhibiting the lower buds from growing - which should give me good sideways growth.

The Oaks are also doing the Lamas thing. I’ve allowed one of the Oaks to grow unchecked and its growing at a massive rate - this one is due for some strategic pruning soon. For taper I am also trying to keep the top end of the oaks in check and get the side branches working.

This Oak wanted nothing to do with hormones and simultaneously elongated everything.

These are my first generation of field / large container grown trees. They contain many mistakes and I see them purely as a learning exercise. Useful for acquiring technique - something large and cheap to try stuff out on. I don't expect and good bonsai material out of these - although the little beach is looking nice. 

I planted what I would call second generation trees at the beginning of this year. I’ve allowed them to establish roots and will do some early wiring to the trunks to get something interesting happening there - none of that hyper contorted leaping dragon nonsense - just a bit of interest.

As usual the cat has been overseeing matters.
