It is a grass-like plant that requires moist soil and full sunlight for optimal growth. The plant is ideal for growing in indoor aquariums, wetlands, or as a backyard water feature. The best way to cultivate spikerush is by planting it in containers or directly in the soil.
Watering needs
Spikerush requires consistent moisture to thrive. It is essential to keep the soil moist, but not too wet, to prevent the plant from rotting. Water should be added to the container or soil when the top layer feels dry to the touch. During the hot summer months, it is essential to water the plant at least twice a day to keep it hydrated.
Fertilization
Spikerush does not require frequent fertilization. It can survive in soil that is rich in organic matter and nutrients. It is essential to avoid over-fertilization, as this can lead to the growth of algae and other unwanted organisms. However, a light dose of all-purpose fertilizer can be applied twice a year to encourage growth.
Pruning
Spikerush does not require frequent pruning. However, it is essential to remove any yellow or dead leaves regularly. If the plant becomes too large, it can be thinned out by removing the older stems. This will ensure that the plant stays healthy and does not become overcrowded.
Propagation of Eleocharis smallii Britt. var. major (Sonder) Seymour
Eleocharis smallii Britt. var. major (Sonder) Seymour is commonly propagated by two methods: by seed and by division.
Propagation by Seed
The most common propagation method for Eleocharis smallii Britt. var. major (Sonder) Seymour is by seed. To propagate by seed, the ripe seeds are collected from the plant and stored in a cool, dry place until ready to plant.
To plant the seeds, a seed tray or pot is filled with a moistened seed starter mix. The seeds are then scattered over the surface of the soil and gently pressed down into the soil. The tray or pot is then covered with plastic wrap or a plastic dome to help keep the soil moist and warm.
The seeds typically take 10-14 days to germinate, depending on the temperature and moisture levels. Once the seedlings have emerged, the plastic cover can be removed, and the seedlings can be transplanted into individual pots or into the desired planting area.
Propagation by Division
Eleocharis smallii Britt. var. major (Sonder) Seymour can also be propagated by division. This method is typically used when the plant has grown too large or has become too crowded in its container or planting area.
To propagate by division, the plant is carefully removed from its container or planting area. The roots are then gently separated, and the plant is divided into two or more smaller sections. Each section should have a good amount of roots and some healthy green foliage.
The divided sections can then be planted into their own containers or into the desired planting area. It is important to keep the soil moist and to avoid disturbing the newly planted sections until they are well established.
