As some of you probably know, I live in the high desert east of LA. Yesterday night when I was watching the news, high winds were on the forecast for my area. I didn’t think much of it because we get lots of wind often (it is a desert region after all…).
The winds turned out to be much more powerful. Winds were and are at 35mph and gusts up to 60mph, and are expected to calm down sometime around midnight. As I was coming back home from class (over the mountains into the desert), I saw that the sky seemed very cloudy, but was all the dust and sand! So, I get home and see a bit of sand on the LFS that is topdressing my CPs. It wasn’t a lot; just enough to partially cover my fingers a bit. I usually don’t leave their pots standing in water (I top water) because the winds carry sand and over time they leave a nice deposit of sand in the water trays. My plants are inside now… overnight temps are expected to drop into the 30’s too.
So my question… Should I remove and replace the LFS that has that bit of sand on it? Can the sand be potentially harmful to the CP’s if I top water as they are now? I know some people use sand in their CP growing media, but I don’t think desert sand is considered clean… Any other tips? From now on I’ll put my plants inside whenever there’s a wind advisory.
