Narrowleaf Water-Starwort

Narrowleaf water-starwort (Callitriche brutia var. hamulata) should be watered regularly, but it does not need large amounts of water. It prefers moist soil, but make sure the pot has drainage, as this plant does not like wet roots. During the spring and summer months, water about twice a week, if the soil is dry 1 inch below the surface. In the winter, water very sparingly, as this is the plant's dormant time of year. Make sure to evenly distribute water during each watering, and always allow the top inch of soil to dry between waterings.

Narrowleaf Water-Starwort (Callitriche brutia var. hamulata) grows best in bright, indirect sunlight for at least 4-6 hours a day, with the best exposure coming between midmorning and mid afternoon. The plant is capable of thriving in full sun for a few hours if the afternoon sun is filtered properly with shade or dappled light, but it is best for the plant to avoid being in direct, hot sunlight for extended periods of time.

Narrowleaf Water-Starwort requires minimal pruning to maintain its shape and size. Prune in early spring, as new growth begins. To do so, simply snip off any old, dead or dying stems at the base. For larger, fuller plants, you can also prune back some of the outwardly growing stems to control their size. In general, no more than 1-third of the plant should be pruned in any given season.
