watering

Pedunculate Water-Starwort is a moderately drought tolerant plant species and should be watered when the top 2 inches of soil are dry. It is best to check the moisture levels of the soil weekly to ensure the optimal growing conditions. Water the plant deeply, allowing the excess water to drain out. Avoid overwatering, as too much moisture can cause leaf yellowing and root rot. During hot and dry spells, water the Pedunculate Water-Starwort once per day or every 2 days. The amount of water to use depends on the soil's drainage rate and size, but a general guideline would be to use about 1-2 inches of water each time.

sunlight

The Pedunculate Water-Starwort is a species of aquatic plant which flourishes in full sunlight. This species preferably demands 8-10 hours of uninterrupted direct sunlight. The best time to provide sunlight for this species of plant is from midday to mid-afternoon as that is when the heat is high and sun rays are the strongest.

pruning

The pruning for Pedunculate Water-Starwort should be kept to a minimum; only prune when necessary. It is recommended to prune in late spring around the end of April or the beginning of May once the new growth has started to appear. The best way to prune is to cut back any dead or dying stems as close to the base as possible. Pruning when the plant is actively growing will encourage new growth and increase flowering. It is also recommended to lightly trim away any damaged, diseased or old stems as needed.
