How To Care Geranium Plants. An important tip on how to care for potted geraniums is that geraniums do not need frequent watering. You can either plant these directly in the ground as border plants in flower beds or grow them in containers or a hanging basket.
In addition to watering which should be done deeply and once the soil begins to feel dry indoors or at least weekly outdoors though potted plants may need daily watering in hot weather fertilizing is usually necessary. Whether indoors or out geranium care is pretty basic. You can use specific liquid fertilizer for geraniums or a generic fertiliser.
In winter occasional watering is enough.
Cultivating hardy cranesbill geranium in fertile soil also encourages the plant to spread. You will have to pull off dry and dead leaves from the junction with the stem. Apply a rich soluble fertilizer every two to three weeks and water the base of the plant when the soil is dry. A well-cared-for geranium can live upwards of 20 years.
