 In Buxus disease, Box Blight? Problem with box topiary I wrote about a new, at the time the latest, buxus problem in our garden. Now, about three years later, we know that this is a problem that is here to stay and will not easily go away. In 2002, the cause of a new [...]
Our beautiful Ulmus parvifolia or Elm-tree in The front garden compartment is again partly affected by Dutch elm disease (DED). Well that is to say most parts that survived the previous attack. In July 2011 we had to remove some heavy branches because they had lost all leafs in mid-summer. Although substantial damage, the tree […]
Sagina, called ‘pearlworts’ or ‘Irish-Moss’ (Dutch ‘Vetmuur’) can very well serve as a substitute for moss in a Japanese garden. Unfortunately we have a bad experience with it. In my post ‘Groundcover maintenance’ I wrote about the fact that Sagina is one of our most feared and persistent weeds in the ground-covers, or actually […]
Depending on the weather conditions and plant growth in the garden we have a first preventive spraying round in mid-April. This year we had an early and fabulous spring with summer-like temperatures and little, actually far too less, rainfall. Due to this the insects started their activities very early already and it was no […]

In the Tsubo-en website we have many pages with lessons learned (LL) at the bottom. Recently I started to include LL’s in this diary, classified as such. Having an IT-background, talking about lessons learned reminded me of: “Rule 0: Don’t make a mess of it.” by Edsger W. Dijkstra, a Dutch computer scientist. This […]
In the chapter on mosses, Mosses and lichen, we have a section named Unwanted mosses and that is where this post is about. The unwanted moss here is Hypnum cupressiforme (Dutch: Gesnaveld klauwtjesmos), and Hygrohypnum luridum (Hygrohypnum Moss, Drab Brook-moss, Dutch Gewoon spatwatermos). These mosses are very strong growers and survivors. When they first […]
Insects can cause a number of pests. Here we address two insect specimen that, this year, caused a different type of harm. Honeybees and ants. During the work described in my post Trimming the topiary O-karikomi (buxus) sculpture the following strange things occurred. Bees, more specifically honeybees are frequently visiting the boxwood all over the […]
In my post Tuning the hako-zukuri part of our main o-karikomi box topiary, I showed how the center part of the Main garden karikomi was trimmed. This was done because keeping the hako-zukuri part in the desired shape is much more time-critical than that of the parts. Where sometimes one annual trimming is sufficient […]
This year for the first time the boxwood topiary across the garden have dead branches. In most cases these are small branches but some instances are more serious and in one case it is a substantial part of a plant that is part of the o-karikomi and is highly visible. One of four plants […]
