How to Care for an Oxalis Iron Cross
- 1). Plant Iron Cross in a sunny spot. Most oxalis varieties prefer shade, but this one is an exception. Select an area where the soil drains well and has a light, loamy or sandy texture.
- 2). Dig holes as deep and slightly wider than the root ball. Space the planting holes 6 to 12 inches apart.
- 3). Push soil around the roots and pat down the soil gently with your hands. Apply water to the planting area to settle the roots and reduce transplant shock.
- 4). Fertilize the plants once a month using a balanced fertilizer. The University of Oklahoma Department of Botany and Microbiology recommends diluting the fertilizer to half strength.
- 5). Water Iron Cross when the top 1 to 2 inches of soil start to feel dry under your fingers. Soak the area to a depth of 4 to 6 inches, then allow the soil to dry out before you water again.
- 6). Divide Iron Cross plants in the spring when new growth begins to appear. Dig up a section of a plant, and pull it or cut it into sections, each containing three or more growing shoots.
- 7). Replant the divisions a new area in the garden or in pots. Use a mix of 2 parts peat to 1 part loam.
