Droopy leaves and leggy roots are a sign for you to prune. Make small cuttings about ½ inch below the node and remove ⅔ of the growth for a fuller horizontal appearance. You can use the waste foliage as compost fertilizer for newly propagated plants.

Best Soil for Whale Fin Plants

Native to stony soils in The Congo, the whale fin plant does well in most soils. However, the ideal soil condition is porous soil with more grit than organic matter and a neutral soil pH. A mixture of 2 parts of cactus soil and 1 part pumice is ideal for Sansevieria’s growth.

The most effective way for propagating Sansevieria is by division at the roots. Snip through the root up to the node and stick it in soil with about an inch’s length of water. However, you can use water propagation which prevents newly developed roots from breaking off. Water propagation procedure

  1. Make leaf cuttings at the nodes.
  2. Tape the leaf-cutting to the sides of a water trough
  3. And put it in the sun.

After a few months, the long roots will grow, signifying maturity and readiness for soil implantation.
