'Black Magic' Series is a zonal pelargonium with rounded, chocolate-brown leaves, and large clusters of bright red, rose, appleblossom and salmon flowers in summer and autumn. Two of its components are Award of Garden Merit winners.
Because you need to water geraniums thoroughly and deeply, take the time to leave an irrigation furrow around each plant to serve as a watering reservoir. This allows the water to pool and then gently filter down through the soil.
Geraniums require light fertilization. If you feed them too much, the foliage will flourish at the expense of the blooms.
The perfect soil for geraniums is a loose soil with plenty of organic matter. If your soil is on the heavy side, incorporate peat, compost or perlite. Manure and vermiculite are not recommended.
They also need indoor temps of around 65-70 degrees F. (18-21 C.) during the day and 55 degrees F. (13 C.) at night.
