Exotic holiday pleasures in a preserving jar
- Put some sand or pebbles in the glasses.
- Place the plants inside (1 plant per jar) and fill them up to the edge with sand or pebbles. If you are using smaller jars, e.g. 8 cm in diameter, and there is little space between the root ball of the plant and the glass wall, help to fill the sand or pebbles with a fine stick so that the sand (or pebbles) is distributed evenly.
