How to Propagate Gloxinia

Seeds

• 1

  Place a shard of pottery over the hole in a clay flowerpot to prevent soil from falling through.

• 2

  Add 1 inch of gravel to the bottom of the pot, then fill it with sterile potting soil.

• 3

  Sprinkle gloxinia seeds on top of the soil, spacing them evenly. Do not cover the seeds with soil.

• 4

  Place the pot in a container of water to soak up water from the bottom. Seeds dislodge when you pour water on the surface of the soil.

• 5

  Place plastic wrap or a piece of glass over the pot, and put it in a warm place with indirect light. Keep soil damp by placing the pot in a saucer of water. Remove the plastic or glass when seeds germinate in six to 10 days.

• 6

  Transplant the seedlings to individual 4-inch containers filled with potting soil when three sets of leaves appear.

Cuttings

• 7

  Cut a leaf with a stem, as close to the main stem as possible.

• 8

  Insert the cutting into a flowerpot filled with equal amounts of construction sand and peat moss, or place the stem into a glass of water.

• 9

  Place the cutting in indirect sunlight, and keep the planting medium moist, or replace the water when it evaporates or looks cloudy. Roots should form in several weeks.

• 10

  A small tuber may form at the end of roots in the glass. Plant gloxinia seedlings in pots filled with potting soil when the roots get 1 to 2 inches long.

Tubers

• 11

  Fill a 5-inch or larger pot with sterile potting soil.

• 12

  Place the tuber, rounded bottom down, in the soil, and cover it with soil so it sits just under the surface.

• 13

  Place the pot in an area at 65 to 70 degrees Fahrenheit, and water every three to four days from the bottom. Do not let the soil become dry.
