Marsilea drummondii can grow with minimum fertilization given its natural growth environment. Nonetheless, providing fertilizers can help boost their growth rate. In nutrient-poor sediments, the addition of nitrate and phosphate fertilizers can improve the plant's growth rate. It is essential to fertilize with caution since excess nutrients can be detrimental and cause overgrown algae and decay the plants around.
Pruning
Marsilea drummondii is a slow-growing plant, and pruning is not necessary, However, periodically removing dead or damaged leaves and runners can help promote new growth. When removing unhealthy plant parts, ensure not to damage the healthy ones. Use plant scissors or garden shears to cut off the leaves or runners and make sure to sterilize the tools beforehand.
Propagation of Marsilea Drummondii
Marsilea drummondii, also known as the dwarf waterclover or nardoo, is a perennial aquatic plant that can be propagated through spores or division.
Propagation through Spores
When propagating through spores, mature plants are submerged in water for 24 to 48 hours to stimulate spore production. The spores are then collected and placed in a suitable growing media such as damp sand or peat moss. The growing media should be kept moist and placed in a warm and well-lit location until the spores germinate. Germination usually takes around 14-30 days. Once the spores have germinated and the plants are large enough to handle, they can be transplanted into a larger container or planted in a pond.
Propagation through Division
Propagation through division is the easiest method, and it involves separating and replanting the new plantlets. In this method, mature plants are carefully removed from the water and washed in a clean container to remove any debris. The plants are then divided into smaller portions along the rhizome. Each portion should have at least one healthy stem and root system. The divided portions are then planted in a new container or pond and should receive appropriate care until they have established a healthy root system.
Propagation of Marsilea drummondii is an easy and straightforward process that requires little expertise. With proper care and attention, these plants can produce a beautiful aquatic garden in no time!
