Ulmus parvifolia, Elm-tree pollarding and thinning

Ulmus-parvifolia-twinsIMG_1992

A previous post was named Ulmus parvifolia, Elm-tree prunning and was about interim pruning. This post is about the annual pruning, in particular topping and thinning to retain the desired size and shape. This is also called pollarding, the annual removal of all of the previous year’s growth, resulting in a flush of slender [...]

Trimming the Taxus baccata (yew) hedgerow

taxus-bacata-ladderIMG_3882

Trimming the Taxus baccata hedgerow  (common name yew, or European yew) we mostly do this only once a year. In general this hedgerow does not perform well. We expect two reasons for that, one being the water household is not okay and secondly, on the other side, there are too many plants too close [...]

Tuning the hako-zukuri part of our main o-karikomi box topiary

okarikomi-main-center-resultIMG_3867

Depending on the annual growth-cycle trimming of the O-karikomi in the main garden happens once or twice per annum. Tuning the hako-zukuri part of this O-karikomi box topiary ‘sculpture’ is done at least twice a year. Because the hako-zukuri and karikomi objects in the center part are much smaller it is important to threat [...]

Chamaecyparis Lawsonia trimming

Chamaecyparis-trimmingIMG_3840

Next to our Cryptomeria Japonica (Lawson’s Cypress) “elegans” stands the Chamaecyparis Lawsonia “white spot”. After I had pruned the Cryptomeria ( post: Cryptomeria Japonica “elegans”, fukinaoshi-pruning ) I pruned the Chamaecyparis. We prune our Chamaecyparis Lawsonia for shape. This pruning is part of a long running fukinaoshi treatment that entails pruning for shape and applies [...]

Buxus disease, Box Blight? Problem with box topiary

buxus-sempervirens-fungusIMG_3893

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 [...]

Nothofagus antarctica, pruning for shape

notofagus-almost-finishedIMG_3746

This is how the Nothofagus antarctica, Antarctic Beech, looked prior to pruning back in 2008. In the years prior to 2008 we have thinned it consistently every year, to be less compact and open than it would naturally grow. We prune the Nothofagus antarctica (genus southern beeches) in the left side garden compartment, for [...]

Cottony maple scale on our Acer Palmatum

Cottony-maple-scale-on-Acer-PalmatumIMG_3965

Cottony maple scale insects (Dutch: wollige dopluis) feasting on our Acer Palmatum what a fun this is. One that has been especially abundant and a frequent visitor of our garden is the soft scale insect known as the cottony maple scale or Pulvinaria innumerabilis. In our case this is a tree that is a [...]

Wisteria sinensis sprouts and runners

wisteria-sinensisIMG_3716

Although Wisteria is not a tree at all, it is a woody climbing vine, on our website we classify it under Deciduous trees. That is because it is trained to be just that. A couple of times per season we remove the longest sprouts. These can quickly become 50 or even 100cm (1.6 to [...]

Powdery Mildew on our Euonymus Japonicus

euonymus-mildew-tobeclippedIMG_3723

We are used to a few annual attacks of plant louse (greenfly) against or Euonymus Japonicus “Compactus” (Japanese Spindle) next to the terrace in the main garden. Mildew we have had only once or twice before. And now it is fully covered by it and hence we identified it as Powdery Mildew (fungi in [...]

Timing for box-topiary trimming

hakozukuri-buxus-clippingIMG_3802

Clipping the box (buxus) topiary karikomi, o-karikomi and hako-zukuri, is probably more time critical and weather dependent, than any other clipping or pruning. Trimming the box (buxus) topiary karikomi, o-karikomi and hako-zukuri, involves cutting back the fresh new growth. When and how often this needs to be done very much depends on where you [...]

Larix (Europeaus) decidua, fukinaoshi-pruning

larix-extralongprunerIMG_2044

We prune our Larix (Larch) for shape. This pruning is part of a long running fukinaoshi treatment and entails pruning for shape and applies to most of our tall trees. We started this activity in 2008, after I got hold of the book “Niwaki” by Jake Hobson. I will later write a book review [...]

Insecticide, second or third annual overall treatment

IMG_2645w356

Depending on the weather conditions and plant growth in the garden we have a first preventive spraying round in mid-April. Sometimes one or two weeks earlier other years one or two weeks later but that is the schedule. Depending on how serious the problems are and how effective the first treatment was, e.g. was [...]

Karikomi style Prunus lusitanica, pruning for shape and growth

karikomi-prunusIMG_3613w350

Although rather distant, this object is part of the Mountain-range structure at the other site of Mount Sumeru and a visual part of the O-karikomi style Prunus lusitanica element discussed in the earlier post. This Karikomi (Prunus lusitanica, common name Portugal laurel) is part of a mountain-scape formed by it and the O-karikomi to [...]

O-karikomi style Prunus lusitanica, pruning for shape

o-karikomi-prunusIMG_3607w350

This topiary, representing a mountain-range or a mountain-scape, gets pruned and clipped in the so called Karikomi style (see: Karikomi and hako-zukuri, topiary technique of clipping shrubs and trees into large curved shapes or sculptures). As indicated above the “o” prefix in O-karikomi means “large” and it refers to the use of groups of [...]

Ulmus parvifolia, Elm-tree prunning

ulmus-prunningIMG_3600w350

At the left side of our Tsukubai in the front garden grows the Ulmus parvifolia “seijn” (elm, top of photo). It is trained in the “twins” (sokanshitate) style. The robust trunk has a very thick flacking cork-like bark even when the tree is very young. This in combination with the very small leathery, lustrous [...]

Hako-zukuri style Prunus lusitanica “tree”

karikomi-prunus-clippingIMG_3593w350

The Prunus lusitanica and the triangular Buxus sempervirens in front of it need regular clipping and pruning to keep the proper shape. Both get pruned and clipped in the so called Hako-zukuri style (see: Karikomi and hako-zukuri) (shrubs clipped into boxes and straight lines). The Prunus lusitanica is a strong grower and needs to [...]

Armeria Maritima flowering, continued

armeria-maritima-flowerclippingIMG_3648

In my prior post, Armeria Maritima flowering, caution ! (Marsh Daisy). I told about timely removal of the flowers. Now while removing the remainder (enjoying the flowering as long as possible) of the flowers, I realize that how I do this can be a useful tip for our readers. So here it is. Cutting [...]

Tsukiyama, the edges in the main-garden

edgestoolsIMG_3558w350

The weather is great for gardening. Partially overcast and around 20 degree Centigrade (68 °F). After the Tsukiyama/gravel-edges in the front-garden we did a couple of days ago we yesterday clipped the Leptinella Tsukiyama / Ginshanada-edges in the main-garden compartment as described in post ‘Tsukiyama, the edges in the front-garden’. Some job, because the length [...]

Tsukiyama, the edges in the front-garden

edgesIMG_3557w250

Most of the Tsukiyama surface is covered by the same species of a low growing ground covering plant. Like in our previous post about the Turtle Island groundcover, we also want to keep these edges, that is the Tsukiyama (land) gravel (sea) junction, razor-sharp. This is far more difficult as the Leptinella (aka Cotula) grows [...]

Razor-sharp thyme edges

thymetoolsIMG_3552w350

Most of the “body” of the Turtle Island is covered by Thyme, Thymus Praecox pseudo langinosus (see Groundcovers). The Thyme grows beautifully and is a slow creeper. We like to keep the edges razor-sharp, like they where painted, and this Thyme is ideal for that. It can be left unattended for a while and will [...]
