3 Tiers Shaped on a Ligustrum Delavayanum Cloud Form with Okatsune 217 Shears

Ligustrum delavayanum holds cloud pruning well, which explains why nurseries sell it for this use. Its young wood bends readily, then hardens quickly, and it will backbud along older stems where bay or box can sit sulking after a hard cut. In a three-tier cloud form, three separate foliage clusters sit up a bare trunk, with clean lengths of visible wood between them. The work is selective removal: excess shoots come away until the tier structure can be read clearly.

Stand with the plant for longer than feels natural before cutting. Ten minutes is a sensible minimum. The existing trunk decides where the tiers can sit, and no amount of wiring will make a dead-straight stem with no movement look convincing. Grafted delavayanum stock often has a low kink at the graft union, roughly 100 to 150mm above the soil, and that bend commonly gives the first tier its anchor point.

The Okatsune 217 and the cut it makes

The Okatsune 217 is a 200mm shear with a straight blade and scarlet-and-white handles. Those handles are easy to see in long grass, which is the practical reason plenty of owners first wanted them.

For cloud work, the straight blade has an advantage over a curved topiary shear because the cut is made on individual shoots at the surface of the pad. The last 30mm of blade does the useful work. Cutting deep in the throat of any shear tends to crush the stem, and on Ligustrum that crushed end can brown back 5 to 10mm over the following fortnight. On a clipped pad, where every exposed leaf and shoot tip is visible, those brown flecks show.

The 217 will stay sharp through a full day of soft summer growth. Woody stems over about 6mm are enough to dull it, so those cuts move to secateurs.

Close the shears before setting them down. An open Okatsune left in wet grass can rust at the pivot within a season, and the pivot controls whether both blades stay in contact along their full length. At the end of the day, wipe away sap with a cloth and a splash of white spirit. Sap left overnight turns into a black lacquer that drags on the next cut.

Commit the trunk line first

Strip the trunk between tiers before shaping the pads. This step feels severe, which is why it often gets delayed, but a mist of small shoots between tiers makes the whole tree read as a fuzzy shrub even after careful clipping.

Choose the three pad heights from the plant in front of you. On a plant around 1.4m tall, a common arrangement places pads near 500mm, 900mm, and at the crown, although the branch positions matter more than a measured diagram. Wherever a strong lateral leaves the trunk at about the right height, it can become a pad. Shoots on the trunk between those laterals are removed flush.

Use Felco No. 2 or No. 6 secateurs for material the shears cannot cut cleanly. Felco maintenance belongs in the job. A nicked blade tears the bark collar when a trunk shoot is cut flush, and Ligustrum bleeds sticky sap that seals torn tissue slowly, with dieback more likely around the wound. Strip the Felco, work the edge with the grey Felco 903 sharpening stone at the factory bevel angle, and oil the spring. A well-set pair closes without side play. If a gap can be felt through the handle as the blades pass, the adjustment bolt has loosened.

Make trunk cuts flush to the bark and avoid stubs. Stubs on a clear trunk are one of the ugliest marks on a neglected cloud tree because they catch light and draw the eye. On stems of this size, a flush cut usually calluses over within a season.

Watch the graft union as the plant starts moving again. It may throw suckers from below the union, and on delavayanum the rootstock is often a coarser privet with larger leaves. Rub those shoots out with a thumb as soon as they appear. Once they lignify, they become a yearly cutting job for the life of the tree.

This trunk work also decides which parts of the plant receive the next few years of growth. If a pad is clipped and encouraged for a summer, then removed later, it has already thickened and pulled strength toward the wrong place. The tier that should have been favoured is weaker because the structure was left undecided.

The summer window

Clip the pads during the summer growth window, roughly late June through August in a temperate climate. At that point the season’s shoots have hardened at the base while the tips remain soft, and a single well-timed clip can keep a Ligustrum cloud form crisp into autumn.

Late spring cutting, when sap is running hard and the shoots are fully soft, produces a green fuzz over the pad within two weeks and sends you back out with the 217. Deep winter cutting on delavayanum carries frost risk through fresh cuts, and the plant is only borderline hardy below about minus 10C, so exposed tissue is least able to seal at the time it most needs to.

Pad shape, light, and reduction cuts

Each pad should form a low dome, denser across the top, lighter at the edge, with a slightly hollow underside so air and light can pass through. The underside deserves as much attention as the top. A pad clipped into a solid ball shades its own lower leaves and the tier beneath it, and within two seasons bare patches often appear on the north face and under the pads above.

Clip the top flatter than instinct suggests. Over-rounded domes pull the eye upward and hide the clean trunk gaps that make the three tiers legible. Keep the lowest tier largest in diameter, the middle tier smaller, and the crown smallest, since that graduation keeps the plant in proportion and allows more light to reach the lower branches.

Work from the crown downward. Clippings fall onto uncut tiers below, so finishing the top first saves you from picking debris off lower pads that have already been shaped. Cut the crown, brush it clear by hand, then move to the middle tier and finish with the base.

Over several years a pad can become too thick from front to back. Reduce it hard in one summer by cutting back to a fork inside the pad, below the green surface, into two-year wood. Delavayanum backbuds reliably from old wood, so a pad reduced to bare stems can refurnish within a season or two. This is the cut that stops pads creeping outward and closing the gaps between tiers. A cloud form that has gone five years without this internal reduction starts to look like a lollipop with lumps.

A few sideways shoots beyond the pad line are better pinched with finger and thumb than sheared. Pinching leaves no cut leaf edges to brown, and on a close-viewed pad those browned half-leaves can make the surface look untidy even when the outline is accurate.

A short note on wire

A young delavayanum branch can be wired to set a pad angle, using aluminium bonsai wire around 3mm. Leave it on for one season only, because wire that bites into the bark scars for years.

The time built into the price

A nursery-bought, pre-formed delavayanum cloud tree at 1.2 to 1.5m costs serious money because someone has already spent three to five years building the trunk line and pads before the plant reaches the sales bench. Starting from a plain shrub, the trunk stripping and first definition of the tiers can be done in one afternoon.

The dense pads and clean gaps take longer. Expect three summers of a single annual clip, with occasional pinching between those cuts, before the form reads clearly.

Delavayanum keeps trying to return to a rounded shrub. Every tier cut leaves an empty space below it, and the plant answers by pushing new shoots from the clear trunk, which then have to be rubbed away again and again. The unresolved part is whether that standing argument still feels worth the shape once the plant keeps trying to become a shrub again.
