Preparing the Planting Materials

A uniform propagation guide for the nursery

Published

Sep 2026

This guide explains how to prepare uniform planting materials from healthy mature plants already growing in the garden. The correct material depends on the plant. Use stem cuttings only where suitable; use divisions, offsets, plantlets, leaves, rhizomes, tubers, corms or seed for other plants.

Standard procedure for every batch

  1. Select a healthy, vigorous and correctly identified mother plant. Do not use material with pests, disease, yellowing or weak growth.
  2. Water the mother plant the evening before collecting material.
  3. Collect early in the morning and keep the material shaded and moist until planting.
  4. Clean pruning shears or a knife with 70% alcohol before starting and between different mother plants.
  5. Prepare all pieces in one batch to the size shown in the table. Keep only strong pieces of similar thickness.
  6. Remove flowers, flower buds and damaged leaves. On stem cuttings, remove leaves from the part that will be buried but keep two to four healthy leaves at the top.
  7. Label each batch with the plant name, mother plant, preparation date, number planted and propagation method.
  8. Plant each batch in the same bag size, at the same depth and on the same day. Keep batches together in straight, labelled rows.
Important

Never leave fresh cuttings in direct sun. Keep the rooting medium evenly moist but not waterlogged. Succulent and latex-producing cuttings need time for the cut surface to dry before planting, as shown in the table.

Catalogue completion

Every plant formerly listed in the planting-material table now has a complete master profile in the Plant Catalogue. Use the profile for the exact planting material, size, preparation method and number per nursery bag.

Making nursery plants look uniform

Grade the material before planting

Create three temporary groups: small, medium and large. Plant only one grade in each batch. Use medium-sized, vigorous material for the main sale batch. Keep smaller material in a separate recovery batch and do not mix it into the main row later.

Use one standard per batch

For every plant batch, keep these items the same:

  • mother-plant type or cultivar;
  • propagation method;
  • cutting, division, offset or corm size;
  • number of pieces per bag;
  • nursery-bag size and media volume;
  • planting depth;
  • preparation and planting date;
  • shade, watering and feeding schedule; and
  • pinching or pruning date.

Produce flowering batches together

For chrysanthemums, marigolds, petunias, carnations, geraniums, impatiens, portulaca and similar flowering plants, prepare or sow each batch on the same day. Use material of one variety and one size grade. Remove any flowers and buds at planting so the plants first establish roots and vegetative growth.

After establishment, pinch plants in the same batch on the same day where pinching is appropriate. Do not pinch African violet, African lily, aloe, anthurium, bird of paradise, caladium, daylily, echeveria, gladiolus, peace lily, snake plant, spider plant or ZZ plant.

Note

Planting together improves uniformity but does not guarantee that different plant species will flower at the same time. For a coordinated display, manage each species as a separate dated batch and combine only batches that reach flowering stage together.

Batch label and record

Use a code such as CHR-20260915-A, meaning chrysanthemum, planted 15 September 2026, batch A.

Batch code Plant Material and size Mother plant Date prepared Number planted Bag size Expected review date Notes

At each review, record the number alive, the number rooted, weak plants removed, pest or disease signs and any differences in growth. These records will help refine the best cutting size and method under the nursery’s actual conditions.

Practical safety notes

  • Wear gloves when handling Crown of Thorns, Graceful Spurge, Poinsettia and other plants that release irritating latex.
  • Crown of Thorns also has sharp spines. Keep it away from children during preparation.
  • Do not propagate from diseased mother plants, even if some branches look healthy.
  • Wash tools and hands after each batch and keep plant labels with the plants at all times.

The general preparation standards in this page follow established guidance for vegetative propagation: healthy stock plants, clean tools, at least two nodes on most tip cuttings, removal of lower leaves, a well-aerated rooting medium, high humidity without waterlogging and bright indirect light.
