Ivy geraniums, or Pelargonium peltatum as they are scientifically known, are fun plants to grow in hanging baskets. Although they can be used as ground cover or grown in beds, they are perfectly suited to container gardens. Ivy geraniums have different care requirements than their common, or zonal, cousins, especially when it comes to light and temperature requirements. There are differences between varieties of ivy geraniums as well, so read the tag that comes with the plant. Ivy geranium is hardy in USDA zones 9b to 11.
Plant the ivy geranium in full sun. If your temperatures climb over 85 degrees Fahrenheit, make sure the plant will receive shade in the afternoon.
Water the geranium when the soil dries out to within 1 inch of the surface. The ivy geranium has specific water needs and, at first, it will be a challenge to determine what those are in your garden, with your type of soil. Water regularly, as inconsistent soil moisture can cause edema.
Fertilize the geranium with a water-soluble, all-purpose plant food once every two weeks, when you water.
Inspect the geranium for common pests such as spider mites, mealy bug and thrips. Consult with your county extension agent to determine the best treatment for your area.
