Fill your trays with a moistened medium. Sow the geranium plant seeds evenly and then add a dusting of medium over them. You need to cover the flat or tray with plastic wrap or a clear plastic dome. Place them in bright light. Geranium plant seed propagation requires temperatures of at least seventy-two degree Fahrenheit but no higher than seventy-eight degree Fahrenheit where germination can become inhibited. Make sure you remove the plastic cover daily to allow excess moisture to escape. Once you have seen 2 sets of true leaves on the seedlings you can easily move them to larger containers to grow in. Plant the seedlings with cotyledons under the soil. You can place the plants under fluorescent lights or in a very bright location. Ideally, the geraniums should have ten to twelve hours of light per day. Make sure you water the plants when the surface of the soil is dry to the touch. You can also fertilize weekly with houseplant food that has been diluted by ¼. You can harden the plants off for about 7 days before planting them out and then wait patiently for a host of blooms.
