Either you are a tiny miniature human being the size of a postage stamp, or that tree is really big. Cool pics, thanks!

Thought I'd give an update just in case anyone winds up searching these forums with a similar problem: Been watering it WAY more than I ever thought I should be. Decided that worst case I would loose the plant which is no big deal. The plant has perked up and now looks more like the others. It has grown more than twice it's size since I posted this question and looks all around healthy now (better colour etc). Still no signs of new growth however. Thinking it's too late in the year. I'm realizing that I've been seriously under watering all my plants. Living in wet BC Canada has made me deathly afraid of overwatering, but I think it's been at the expensive of the health of my plants. I've killed more airplants than I can count from lack of water! I'm watering 3-4 times more now than I was last year and all my plants seem to love it. Growth spurts all around. My mix is extremely fast draining and I wasn't allowing the mix to stay wet for long enough when I did give my plants their infrequent waterings. This was my only lithops in tera cotta (he's now in plastic like the rest) which I think was the reason it was different than the rest. Anyway, I'm loving learning how to properly keep these little guys alive even though I feel terrible for keeping them dehydrated for so long!

I know this is an old thread, but information is information. Some succulents and cacti, I'd say most probably, can and will regenerate farina -- just usually not under the conditions it's going to find in a home. The epiticular wax is made by the plant to protect it from UV exposure and water loss (along with insects and bacteria and all sorts of other stuff, but those are the big ones). In a home growing environment most cacti and succulents barely get enough light to thrive, much less so much that they must protect themselves from it. Same with air movement -- nothing is going to re-create the winds of variable speed, direction, and humidity that they'll get outside. My advice is first, to treat cacti/succulents, especially those with delicate wax, systemically, especially if they'll never be outdoors in bloom. But when you have brushed/washed it off, or altered it in some way, you can try to encourage it to re-grow by giving your plant absolutely as much light as you possibly can, and gently water-stressing it. A room with low humidity and a fan, too, if you can manage it. Any stretch of time that it can spend outdoors will be huge; many of my graptoverias and what have you lost their farina during the Great Mealybug War of '19, but I put them outdoors in mostly-full sun for a good portion of the summer, and by the time I brought them back indoors you couldn't tell anything had ever happened to them, and not just from new growth.

Bernard - yours doesn't look like puill bug, but very unclear. save - that's why I said to google, since you have seen it 'up-close'. You are right, very difficult to take good photo, those things are very fast. I was to suggest that it is possibly one of the bugs that live happily in compost...there are billions of them! Bernard is on the right trail, springtails are compost lovers. They love moist conditions - exactly what happens under the pot (in the saucer). Springtails are soil micro-arthropods Springtails, or collembola, are primitive hexapods (six-legged arthropods) that are closely related to insects. These small critters (1-6 mm, usually less than 3 mm) live in soil, leaf litter, and other damp organic material. Springtails can be extremely abundant in some damp, highly organic soils. They generally cause no harm to garden plants but may be so abundant that they become a nuisance. Very occasionally they damage tender, young garden plants by feeding on roots. Springtails may be nearly colorless to white or gray and even yellow, orange, red, or green. The name "springtail" comes from an ability to spring forward, or jump, by releasing an appendage that is normally tucked under the abdomen (right, lower drawing). All stages except the egg are similar in shape. When springtails are abundant the cause is usually high soil moisture and/or highly organic soils. .................. In either case simply sweeping them up is the best strategy, no insecticide treatment is needed. Springtails won't breed indoors, except in houseplant soil, and won't cause any harm. Outdoors the "invasion" will stop once the rains cease and soils and leaf litter dry out. Treat houseplant soil by allowing it dry out between watering as well. From: springtails/collembola I have seen silverfish in damp saucer - they are common in moist areas (kit, bathrooms) in apartment building - they travel up & down...yucky, but won't harm you. Rina
