Today, the terminal bud started definitively growing. There is no longer any doubt that it is alive and that last years’ growth did not go down the drain. Persimmon seeds are rare, so I am a bit fussier about this tree than I am for example about pomegranates or hibiscuses. So these last two weeks I was worried that the terminal bud is dead.

However, I did not worry that the tree itself is dead. Because it did, in fact, begin to grow just one day after my last post. Only it did not start to grow at the tip. It sprouted a second trunk near the base. Which grows slowly, but steadily, ever since. This week the leaves started to get bigger and I have started to turn the plant 90° clockwise daily in order to achieve straight growth.

However, this is not something that I expected. From pictures on the internet I have assumed that Diospyros kaki are small to medium-sized trees with strong apical dominance, akin to apples or pear trees. But this type of growth, where new suckers start growing at the root base and outpace in growth the main stem is usually the domain of shrubs and bushes, like the common hazel Corylus avellana. And even there it usually does not happen during the second year already, it usually takes a few years to establish the main stem first.

I can only speculate about the cause, so here goes: The root-trimming stopped the inhibition of one of the two buds at the base of cotyledons. Those remained underground in this plant, unlike for example in apple, where they rise above the ground. And since cotyledons are modified leaves, they have buds at their base, only those are usually extremely inhibited and do not start growing unless the main stem is damaged.

This gives me some information about the plant.

First, I will see next year what the root system looks like, but this might mean I will get multiple plants out of this, or one plant with multiple stems. Or that it will be very difficult to get bonsai out of this plant at all because the plant has insufficient apical dominance for that.

Second and more important – it means this species should be strong enough to handle even severe trimming and should be able to start growing even from older wood from extremely inhibited buds. That is, in fact, a very good property in a bonsai tree, because those might need to be scaled back occasionally by trimming several years old branches.

So while this was really unexpected and it is a bit weird, It is not bad news and it makes me hopeful that it will go well. We’ll see how the growth pattern develops from now on, I won’t interfere with the trees shape for at least a year at all.
