Question
We live in Tracy, CA.   We have several of these plants and in the last week about 3 of them have fallen over.   Don't think it's the sprinklers hitting them, but don't know why and would like suggestion.   Also have tied them in a "bunch" to help support them back upright, but doesn't look good like that.   Why is this happening and is there anything we can do to prevent it in the future and/or get these back into "shape".   They don't look like they are dying....just "leaning" over too much.   Thanks!!

Answer
Debbie,
Have there been heavy winds lately?  You don't mention if these are newly planted or established grasses. If they are new, my guess is that they were probably pumped up with fertilizer at the grower and not subjected to normal environmental conditions such as wind.  As such, they are weaker then a plant that is established and not over-fertilized. If you think that this is the case just leave them this year and cut them back sometime in late winter - they'll grow stronger next year as long as you don't over water or over fertilize.

If these are established plants make sure that they haven't gotten too much water or fertilizer - make sure that there isn't a lawn nearby that is being fertilized and being kicked onto these ornamental grasses.  Too much water and/or fertilizer makes plants weak, not stronger.  Given a weekly DEEP soaking and two liquid fertilizations in spring and early summer, these grasses stay upright without a problem.

I hope this helps!
