Planting and care
Start with pruning shears for smaller growth. Use loppers, which look like giant, long-handle shears, for growth that is more than half an inch thick. A small pruning saw is handy, as it cuts on both the push and the pull.
Spiral Flag care
Plants have sprawling, mounding habit. Native to the tropical forest, they prefer light shade but can stand full sun if roots are shaded. Use around foundation or near patio or pool; can also be grown in large pots. Plants are dormant in winter and need little water at that time. Provide a winter mulch.
