Planting Dwarf Hairgrass in Aquarium:
It is advisable to divide Dwarf Hairgrass into bunches of only four to six blades of grass. If you add more plants in a bunch then the carpeting speed of this plant will be considerably reduced. Choosing small packs will avoid the roots & runners from competing with each other & the plant will spread quickly under right conditions.
When you trim the roots of the plant then it will help the plant to regain roots quickly with higher energy. As Dwarf Hairgrass carpets using its runners, it can help the plant spread faster in your aquarium.
Use plant tweezers for grabbing the plant by its roots. Plant tweezers are recommended for planting any kind of hairgrass plant in the tank. Your fingers can’t do this job.
Spread each bunch half or one inch apart. An inch is enough gap to excite the plant runners to spread without overcrowding the bunches.
Push the bunches into the fine substrate. Hold every bunch in tweezers & push every bunch slightly into the substrate.
Pull the tweezers out when the bunch is one third inch deep. Make sure that you shake it because it will allow substrate to fit around the roots of the plant. Now you can safely remove the tweezers without worrying about uprooting the delicate blades of dwarf hairgrass.
Trimming will help the plant in spreading & forming new shoots. When you trim the plant, it will force hairgrass to use its energy to make fresh shoots.
