Q.Monkey grass that looks droopy
I planted some new monkey grass plants this fall for a border around a bed. For some reason they all look droopy and flat. Could I be watering too much?

It's possible that you're watering too much, but it's more likely that you're not watering enough. That's the more likely scenario for a beginner's droopy newly-planted plants. It's also possible that the roots are remaining the circle of the grow pot, instead of moving into the surrounding soil. The only way to know the answer is to get out there with your trowel, and start digging. You can remove the soil around a couple of plants to see what shape the roots are in, as well as to see how deeply the water is penetrating, and what is the condition of the soil moisture.
