- Kids like to see things happen quickly. Seeds that have a fast germination period are best for an indoor gardening lesson. because waiting for the bloom will try a child's patience. Use this time to explain what is happening inside the plant to produce the flower. Seeds that germinate quickly include marigolds and chamomile.
- Different containers can be used for a variety of plants. Try starting seeds in a clay pot or forcing bulbs in a small bowl filled with pebbles. Glass jars open a world of interest when bean seeds are planted along the jar walls. Children can see how the seed starts to germinate and grow. Have children estimate how long it will take the plant to break through the surface of the soil to expose a little sprout.
- Plant terrariums filled with cactus plants or other succulents are good indoor gardening ideas for children. Different types of plants or seeds are able to grow in the humid conditions of an indoor terrarium. Bromeliads do well in a warm, humid environment. An old aquarium makes an excellent container to start an indoor terrarium.
