Anyone who has propagated a pothos in a jar of water knows the rhythm. For two weeks nothing seems to happen. Then one morning there's a pale bump at the node, and a fortnight later a tangle of roots. Because the change is so slow and then so fast, memory is a poor guide — you can't really remember when the first root appeared or how long it took the second cutting to catch up. A photo log fixes that, and it's one of the easiest and most satisfying things to photograph consistently.

Set up a small, repeatable station

Propagation happens in one place, which is a gift for consistency. Choose a fixed spot on a windowsill or shelf, and put the jars in the same position every time. Clear glass is best for water propagation, because it lets you photograph the roots directly. A plain background — a white wall, a sheet of card taped behind the jars — makes pale new roots far easier to see than a busy room behind them. Mark the jar positions with small pieces of tape so you can put everything back after changing the water.

Photograph from the same height and side

Decide once whether you're shooting from the front at jar height or slightly from above, and stick to it. Jar height is best for roots in water; a slightly higher angle is better for cuttings in soil or moss, where the interesting change is new leaves. Keep the phone the same distance away each time. A book or a small box as a phone stand makes this trivial. Turn the jars so the same side always faces the camera — rotating a cutting between photos makes it look as if the roots moved.

What to capture at each stage

Different stages call for slightly different shots. A simple checklist keeps the log useful:

  • Day one: the whole cutting, with the node clearly visible, plus one close-up of the cut end.
  • Waiting weeks: the same framing every few days — the point is to catch the first sign of a root.
  • First roots: a close-up at the same distance each time, so root length is comparable between photos.
  • Potting up: one photo just before and one just after, in the same spot.
  • Establishment: switch to a weekly photo of the whole plant as new leaves appear.

Choose a cadence that matches the pace

During the waiting phase, a photo every three or four days is enough; daily photos mostly show water levels and light. Once roots appear, things move faster and two photos a week capture it well. After potting, weekly is plenty. Changing the water is a natural anchor for the photo: you're already there, the jars are already out, and the glass is clean. Many people simply photograph immediately after refilling.

Keep several cuttings organised

Propagation rarely involves only one cutting, and a batch of anonymous jars quickly becomes confusing. Give each cutting, or each batch taken on the same day, its own Journey in SeeMyChange — a Plant Journey for each, or a Custom Journey if you prefer your own naming. Add a note to the first photo with the details you'll want later: which mother plant it came from, where it was cut, and whether it went into water, moss or soil. Search then finds any of them in seconds, even months later.

Use notes to record what you did

The most useful propagation logs record actions as well as appearance. A short note when you changed the water, moved the jar to a different window, or potted the cutting up makes the timeline readable. It also lets you compare methods honestly — two cuttings from the same plant, one in water and one in moss, photographed the same way, will show their own pace without any guesswork. Stick to what you observed rather than conclusions; the photos speak for themselves.

Let the app handle alignment

Small shifts in position make root growth hard to judge, because a jar two centimetres further away looks like shorter roots. SeeMyChange's Ghost Overlay shows the previous photo faintly over the live camera, so you can line the jar up with its last position before taking the shot. Afterwards, the Slider comparison is ideal for propagation: drag across two photos and the new roots appear exactly where they grew. For a whole batch, a short Timelapse from Transformation Studio makes a surprisingly good record of weeks of quiet growth.

Common mistakes that make logs hard to read

Most propagation logs that end up useless fail for the same few reasons. Cloudy water makes roots invisible, so photograph right after changing it, not just before. Condensation on the glass or a reflection of the window can hide the root zone entirely; turning the jar a few degrees away from the light, and keeping that angle, usually solves it. Moving jars between windows mid-way changes both the light and the background, so if you have to relocate a cutting, note it and take a fresh reference photo in the new spot. Finally, resist photographing only the best-looking cutting. A cutting that rots or stalls is just as informative as one that thrives, and a log that shows both is far more honest than a highlight reel. Keep photographing it until you decide to discard it, and add a note saying so — next season, you'll be glad of the record.

Why it's worth doing

A propagation log costs a few seconds per photo and pays off in two ways. It turns a slow, easy-to-forget process into something you can actually see, which is half the pleasure of propagating. And it builds a personal record of what works in your home, with your light and your plants — the kind of knowledge no general guide can give you.

Give each cutting its own Journey and let the photos show you what changed.
