Step 1
Identify the Acetosum Geranium by its fleshy grayish-green leaves. Sometimes the leaves will have red margins. The flowers are star-shaped and light salmon-pink. They may grow up to an inch across. The petals are long and narrow. It may grow up to 2 feet tall and from .67 to .83 feet wide. It blooms from mid spring to mid summer.
-
Step 2
Plant the Acetosum Geranium in dappled to full sun, depending on the zone you are in. If you have a longer, hotter summer, plant in dappled sun, but make sure the sun it gets is the afternoon sun. If you live in an area with shorter summers, you can plant in full sun.
-
Step 3
Water the Acetosum Geranium enough to keep the soil moist--about an inch per week. If the soil seems to dry out, water more, but do not let the soil get boggy. Watering deeply is much better than frequent, shallow waterings as shallow waterings will not afford the entire rootball enough water.

Step 4
Fertilize the Acetosum Geranium with a water-soluble, quick release fertilizer about once every two weeks. You can also use an organic fertilizer such as fish emulsion, but be sure to read the package for instruction, as different brands may have different strengths. Always use a good, all-around fertilizer, unless a soil test shows that the soil is missing a nutrient.

Step 5
Thin the Acetosum Geranium throughout its life. Each year, remove any dead, old or decayed plants. This will help the plant be an active grower, and will keep them from taking over the area, killing other plants. It also helps reduce disease such as powdery mildew or botrytis.

Step 6
Root prune the Acetosum Geranium. Thin out the patch of this plant by dividing the root system. You can make new plants with the roots you separated and replant or give them away. They should be divided in the spring or fall. Root pruning also stimulates new growth.
