Cloud-Prune a Pinus Sylvestris into 5 Pads over 3 Seasons with Niwaki Okubo Shears

July 29, 2024 by Consumer Team · 7 min read

A mature Pinus sylvestris can carry 30,000 to 100,000 needles spread across dozens of shoot tips. Reducing that weight into five clear pads takes three growing seasons of branch selection, candle removal, and needle-plucking, with the Niwaki Okubo shears reserved for the fine surface work.

Cloud-Prune a Pinus Sylvestris into 5 Pads over 3 Seasons with Niwaki Okubo Shears

Season one: map the trunk and choose the arms

Walk around the Scots pine before any blade touches it. On a 3-metre specimen, use loops of jute string to mark the five branches that can become pads: usually the three or four lowest lateral limbs, plus the leading shoot cluster near the apex. The rest of the first afternoon is assessment, because the cuts made now decide the whole outline for the next three seasons.

Scots pine carries branches in loose whorls, left by its single annual growth flush. That whorl structure gives the pad count. If the tree has four usable whorls and a terminal, five pads is realistic. Forcing a sixth pad from a whorl with only weak, pencil-thin shoots gives a thin pad that still looks hungry by the third summer. Count the viable whorls first and let that count set the target, because pine does not readily push new branches from old bare wood in the way yew or box can.

After the framework limbs are chosen, remove the growth between them. Crossing shoots, downward-pointing weak growth, and inner twigs that have been shaded for years come off with a folding saw or Felco No. 2 secateurs. The cuts are removals of unwanted structure, made back to branch collars, with no flush cuts and no stubs longer than 5 mm.

Clear the underside and inner third of each selected limb. The aim is a clean woody stem running outward, ending in a fan of foliage at the tip. By late winter the tree should look sparse and ungainly: five bare arms, each carrying a tuft. That temporary awkwardness means the future pads have been separated enough to read as separate layers.

The Okubo shears have a narrow job

The Niwaki Okubo are single-handed topiary shears with roughly 60 mm carbon-steel blades and long handles that let the whole hand close the cut. On pine, keep them for trimming the outer surface of each foliage tuft into a domed pad after the needles have set; candles are handled by fingers, and woody limbs belong to the saw or secateurs.

Season two, early summer: candles decide density

In May and early June, a healthy Scots pine pushes pale vertical candles from every shoot tip. Left alone, each candle extends 8 to 15 cm. The pad lengthens, the surface opens, and the foliage moves farther from the woody arm that is supposed to support it.

Candle work keeps the pad compact and starts the back-budding that later fills the cloud. Work while the candles are still soft and the needles have not opened. Snap them by hand. On each cluster, remove the dominant central candle completely, then shorten the surrounding side candles by roughly half to two thirds of their length.

Treat vigour unevenly so the surface becomes even. Pinch the strongest candle hardest and the weakest least. By August, the whole pad should have flushed at about one plane, instead of throwing a few strong shoots past the outline.

Steel creates a visible penalty if used at the wrong time. When hardened needles are cut, the exposed tips brown and the pad carries a brown halo for the rest of the year. A clean hand snap taken while the candle is soft avoids that cut-needle edge.

Use a seven-candle tip as a measured example. If the cluster has one central candle at 12 cm, two side candles at 9 cm, and four smaller candles at 6 cm, remove the 12 cm candle at its base. Pinch the two 9 cm candles back to about 3 cm. Pinch the four 6 cm candles to about 3.5 cm. The tip now sits inside a tighter envelope, and each shortened candle can set two to four new buds at the break point for the following spring.

Repeat that across all five pads and the tree gains hundreds of new bud sites in one season. Those buds are the material that eventually creates the dense, cloudlike shell. Scots pine sets its buds at shoot tips and needs this candle-pinch to stimulate interior budding. A hedge of Ligustrum breaks freely from old wood under regular shearing; Scots pine left unpinched keeps moving outward and goes hollow in the middle within two or three years.

Season two, autumn: needle-pluck the interiors

After the candles harden and second-year needles begin to yellow naturally, usually from September, remove old needles from the inside of each pad. Hold the shoot near its base and strip backward with thumb and forefinger. Take the two-year-old needles and leave the current season’s growth intact.

Aim for a visible branch structure inside the pad, with a shell of fresh needles left on the outer 3 to 4 cm. Light and air then reach the interior buds, keeping them alive and encouraging the back-budding triggered during summer. The visual change matters too: the pad becomes a defined dome on a woody arm, instead of a heavy green lump.

A five-pad tree can take two to three hours of this work. Resin will coat the fingertips, and it usually shifts only with turpentine or a citrus hand cleaner. Cutting needles with the Okubo shears leaves brown stubs, while pulling removes the whole needle cleanly at the fascicle.

Thin the upper pads harder, because they receive more light and grow denser. Work more gently on the lower shaded pads, which carry less spare foliage. The goal is separation without stripping the lower levels until they can no longer feed their own buds.

Season three: shear the formed pads

By the third summer, the framework is set, the interiors are carrying buds, and each pad has enough surface foliage to shape. After the year-three candles have been pinched and have set their needles in late July or August, bring in the Okubo shears. Run them lightly over the outside of each pad, cutting only the current year’s soft new growth and staying out of hardened old needles.

Shape the pads as flattened domes, wider than they are tall. Leave a clear gap of daylight between each pad and the one above it. The classic proportion makes the lowest pad the widest, with each pad above it slightly smaller, so the whole pine tapers toward the apex.

Stand back after every few cuts, at least 3 metres. The outline reads from distance, and a pad edge can disappear quickly when the blades are working close to the foliage. Sharpen the Okubo on a fine waterstone before starting, because a dull topiary shear crushes needle bundles instead of slicing them, and crushed tips brown within a week.

Hold the blades parallel to the pad surface. Work with two or three shallow passes instead of one deep bite. Any woody shoot thicker than about 4 mm should be cut with the Felco secateurs back to a bud.

At the end of year three, the five pads will look defined, even if they do not look finished. Pine gains density slowly through one flush a year. The interior buds built through candle work and autumn plucking need another two or three seasons to bulk the pads into mature fullness.

The maintenance rhythm after year three

From year four onward, the work falls into two regular windows. Pinch candles in late spring to hold the size and drive budding. In early autumn, pluck old needles and lightly shear the domes.

Skipping the candle-pinch for one year lets the pads lunge outward by 10 to 15 cm and lose interior density, which then takes two seasons of harder pinching to restore. Skipping the autumn pluck shades the interiors and leaves the pads hollow. Neither error kills the tree, although both blur the crisp spaces between pads that took three seasons to build.

Site still shows through the technique. A tree on thin chalk with a short growing season back-buds more reluctantly than the same species on deep loam, and no candle schedule fully compensates for that. The unresolved part is visible in the bare interior: how much living bud can be kept close to old wood while the tree keeps trying to spend its strength at the tips.
