Hi all,
I recently bought a 30+ year old jade plant from a person's house contents sale. The woman said she's often sprayed it for pests over the years.
I do not have ANY previous experience with pests, as I'm fairly new to indoor plants. All i know is from looking at pictures online and doing a bit of reading.
1st:
When examining the leaves, there seem to be a lot of leftover carcasses (they seem dead or non-alive enough) on MANY of the leaves... mostly undersides, but on top as well. They're medium brown mounds, edges flush with the surface of the leaf.
2nd:
I'm getting a very fine cottony layer of white on some of the leaves, near the stem... but i don't see any big mealy bugs crawling around. Where this white cottony layer occurs, the leaf area starts darkening to a grey/purple.
3rd:
Among some of the trunks of my jade plant, and stretching across some nearby branches, are fine webs. If i look VERY closely, i can see tiny white critters nesting in these webs. Are they healthy NORMAL spiders... or evil spider mites, I'm wondering?
I'm attaching pictures that illustrate the 3 items above. Please chime in with your observations and suggestions.
Thank you!
