Plant Propagation by Stem Cuttings

Gardening is a very important past time for many people. This program is helpful with general knowledge/understanding of horticulture. The purpose is to build self-esteem, to stimulate the senses and to motivate participants. It can promote socialization, provide an age-appropriate, pleasurable experience, as well as provide an opportunity to nurture. The best stem cuttings come from plants such as Tradescantia (wildflowers), Geraniums, Coleus and Cape Primrose.

Instructions

Preparation

  1. Place table cloth, potting trays, shallow mixing bins, plastic trowels, watering can, soil and vermiculite, plastic tags, markers and face cloths on a table.
  2. Place clippers in a safe place.
  3. Place equal amounts of potting soil and vermiculite in mixing bins.

Activity

  1. Let participant fill the cuttings trays with the soil mixture to a half-inch below rim.
  2. Cut the stem of a healthy plant, at an angle, 4 inches in length.
  3. Remove all flowers and buds to prevent energy expenditure and promote root growth.
  4. Remove leaves from the lower 2 to 3 inches of the stem, leaving the top leaves to produce the food required for growth.

  6. Let participant tamp the soil mixture firmly around each cutting.
  7. Let participant write tags with name of plant and date.
