Root a two- or three-node runner cutting in warm humid mix

FactorRecommendedAvoid
WoodA runner shoot from the base, with two or three nodesDo not take a leafless whip, or a woody old trunk
MixMoist mix that drains; keep it warm and humidDo not sit the cutting in a bog
LeafLeave one or two leaves; bury the lower nodeDo not bury the leaf axil
WaitKeep it shaded and barely moist until new leaves pushDo not pot it on the day you take it, into a cold room

The reliable start for black pepper is a cutting, not a seed. Take it from a runner at the base of a healthy vine — the long shoot that wants to root where it touches mix — with one or two leaves still on. [1] Stolon cuttings from young, vigorous growth root more steadily than old wood. [2] Cut two or three nodes, trim the lower leaf, and set the lower node just into moist mix under shade. [3]

  1. Choose a green runner with two or three nodes and at least one healthy leaf.
  2. Cut just below a node. Remove the lower leaf. Leave the upper leaf on.
  3. Fill a small pot with moist mix that drains. Bury the lower node. Keep the leaf axil above the mix.
  4. Set the pot in a warm, shaded, humid spot. Keep the mix barely moist, never soggy.
  5. Wait until new leaves push, then move it into brighter filtered light. Do not yank it to check for roots every day.

When do I take a cutting?

Take it while the vine is growing, from a green runner, not from a hard old stem. Warm humid air matters more than the calendar.

Do not sow grocery peppercorns — use only fresh seed

Dried peppercorns from a shaker were heated or fully dried. They will not sprout. Fresh seed can grow, but seedlings are uneven, and they take years to match a cutting. [4]

  1. Skip the grocery jar. It is a spice, not a seed packet.
  2. If you have a fresh, untreated berry, sow it soon, barely covered, in warm moist mix.
  3. Keep it humid and wait. Germination is slow compared with a runner cutting.

A fruiting side shoot can make a bushy pot plant, but it will not climb a stake the same way. For warmth, light, and watering after the cutting holds, see How to Grow Black Pepper.

Will grocery peppercorns sprout?

Almost never. Those berries were dried for the mill. Start a live vine or a runner cutting.

Take a two- or three-node runner, bury the lower node in warm humid mix, and wait for new leaves before you move it into brighter light.

FAQ

Can I root a fruiting side shoot?

You can. It tends to stay bushy and does not climb well. A runner cutting makes the usual vine.

Do I need rooting hormone?

No. It can help. A two- or three-node runner in warm humid mix still roots without it.
