How to keep Nasturtium Microphyllum.
Light
Narrow-fruited water-cress is native to habitats such as forest understories or rocky areas that have natural shade. It prefers partial sunlight but can also withstand full sun when necessary. This versatility lets it succeed under different sunlight conditions.
Water
Narrow-fruited watercress thrives in moist environments and needs regular watering, ideally once a week, to maintain its health. This aquatic plant is well-suited for areas near streams, as it requires wet soil or even submersion to imitate its natural habitat. It is ideal for outdoor settings but does not tolerate drought or excessively humid conditions.
Temperature
For Narrow-fruited water-cress, moderate temperatures—similar to those people usually find comfortable—are best. It does well in conditions that are neither too hot nor too cold. The main problem with high temperatures is the possibility of sunburn, so providing some shade in summer is advisable to avoid excessive heat. When temperatures fall, Narrow-fruited water-cress becomes dormant. If continuous growth is wanted, higher temperatures must be kept during winter. Frost can damage the plant and should be avoided.
Pruning
Narrow-fruited water-cress is a hardy, water-loving plant characterized by its narrow fruit. For best results, prune the plant in early to late spring to encourage healthy growth. Remove old stems before the plant flowers to achieve denser foliage and prevent overcrowding. Make sure your pruning techniques allow for adequate air circulation and light penetration.
