Jess, I would,pot up with fresh compost.
Hackonechloa needs moisture but they will grow in full sun. I have several clumps in the ground and in pots in sun and shade. I think they look sensational in large pots. They are slow initially then pick up to become quite vigorous. They love moisture and to give them a spurt water them well occasionally.
They don't need special soil but not free draining. I think the problem is ??ou have given them conditions they simply don't like, viz., too dry
Associate hackonochloa with blue flowers......verbena rigida, salvia patens....or with purple Heucheras. (I do both)
So. Patience jess. Water them and wait
