Need some information on Hairgrass
I've recently bought 15 bunches of eleocharis parvulus to use as a foreground for my tank, but before planting them I wanted to get some advice, namely- what is the ideal distance they should be planted apart from each other to create a 'lawn' like effect?
Will they grow laterally as well as vertically and eventually fill any gaps between bunches?
Oh and one more thing too - can I safely prune them to about half their usual height (I want the well-maintained-lawn look) without damaging or killing them?
Thanks for any light you can shed on any of this for me!
