Broad Leaved Water Plantain

Narrow Leaf Water Plantain should be watered regularly but not excessively. Water the soil deeply, preferably once per week, until water runs out of the bottom of the pot. Allow the soil to dry out slightly between watering. Make sure not to overwater, as this can cause root rot. If growing in pots, make sure the pots have adequate drainage holes.

Narrow Leaf Water Plantain (Alisma gramineum) is a popular aquatic plant species that thrives in full sunlight. This species needs 6-8 hours (or more) of direct sunlight every day in order to remain healthy and maintain its vibrant foliage. It is important to make sure that the plant is not shaded in any way as this will reduce the amount of sunlight it receives and could lead to unhealthy growth. Additionally, during the spring and summer months, when the sun is at its peak, it is important to make sure that the plant gets additional protection from the hot midday sun as this could cause the foliage to dry out or burn.

Narrow Leaf Water Plantain should be pruned once a year in the early spring months. This pruning should involve removing any dead or damaged foliage from the previous season, as well as thinning out the canopy of the plant to allow for better air and light circulation. Pruning should also help encourage the plant to produce more and bigger flowers. It is best to prune off about 1-third to 1-half of the foliage from the plant. This should be done very carefully to avoid damaging the plant’s delicate foliage.
