DaisyL and Sedumzz, and all that are following this thread:
Quick update, and once again, your advice has proven correct.
I am on day 12 of the last watering. As you know, I am testing how far I should go before the next watering without endangering growth or harming any of the plants.
You were right, as none of my 6 jade plants have shown anything near what you described. No wilting, no shriveled, yellow or fallen leaves, and no soft, weak or droopy branches. The soil is dry on the top layer, and the feel test indicates dry soil 2" below the surface. Even the moisture meter indicates dry soil.
The issues with the moisture meter readings continue, as they show inconsistent/slow water evaporation of the soil in two plants. My eagerness to re-water has been consistent all week. But, I'm happy to say I've followed your advice, and held back watering with no adverse effects on the jade plants.
I've learned a few things, and I apologize in advance for "stating the obvious:"
1. Larger plant pots need more time for soil to dry.
2. Ceramic pots need more time for soil to dry than terra-cotta pots.
This website has been a great help, as a little experience and common sense is something I can always use.
Thanks again,
Mark
