After reading what I found on the Internet, I was led to believe the plants I bought wouldn’t need that much watering but it seems like isn’t exactly true. The sansevieria plant I have in particular needs to be watered more than the every three weeks or so that I was led to believe. I’ve taken to watering it every other day and it seems like this is what it needs, at least for the short term. I’m sure it’s a combination of weather and it’s previously dry condition that has led us to this point. The shriveled and brown tips have continued to become less shriveled and green now as I increase the frequency of watering. I will probably keep this up until it looks a bit more healthier.
The dracaena marginata plants I have seem to be fairing a bit better, so I have watered them less, but I still try to keep the soil moist and not bone dry.
We’ll see how the next couple of weeks play out as the summer draws to a close.
