Re: Cool Soil Temps
In San Diego I generally do not take pups after the nighttime temps dip below 60F, even if daytime temps are into the 80s, or sometimes into the 90s (this year as an example). That generally means Oct 15, plus or minus a week or two, is my cut off date.
Cooler weather means less growth, which means less water uptake, less root development, etc. That makes water control more critical to avoid rotting.
Also, plants in pots have cooler temps in their rootzones that in-ground plants. It is much easier to cool off the soil in a 15 gallon pot at 50F, than around an in-ground plant, so the affect of low temps is magnified, and mortality is higher in potted plants.
