How to Grow and Care
Searocket grows and exists in the sandy soil closer to the ocean than the beach grass. Growing Searocket actually prefers sandy conditions. As a succulent, the plant holds water, making growing Searocket even easier.
When growing Searocket, don't include it as part of a vegetable garden. Companions for Searocket cultivation must be of the same family. If the Searockets detect roots of other plants close to it, an "allelopathic" action occurs. Searocket releases a substance into the root zone that stunts or otherwise deter plants of other types.
Searocket puts a long taproot into the soil and does not like to be moved. Start it from the double-jointed seed pods when they appear on the plant and mature, following the small purple blooms. This taproot makes the plant an excellent choice to hold and stabilize sandy soils that may be eroding.
