Just to clarify, I only placed them in my larger outdoor pots while I was outside. Somehow, they found their own way into my smaller- & medium-sized pots all on their own. Which happened while my plants were outdoors. I didn't even know that they were there until I went to soak my pots. And even then, there were only a few of them. All of which were a fraction of the size of the outdoor earthworms. No bigger than the ones in iamhopscotch's photos. They have been there for at least two years now and not once have they ever negatively affected the health of any of my plants. So I pretty much leave them alone. I don't use them to aerate my already fast-draining soil. And even if they "break down" the soil, "Earthworms leave behind excrement or castings containing from 5 to 11 times the amount of nitrogen, phosphorus, and potassium they have ingested." All of which the plants can use.I repot my plants long before the soil gets depleted, and the old soil gets tossed out into the remote corners of my yard, along which whatever's inhabiting it. Even if my new, fresh potting soil were to somehow gain newer earthworms, I wouldn't go out of my way to try and rid them from my pots. People want to try and grow their plants in sterile environments, dousing their plants with fungicides and insecticides, and nature doesn't work like that. I'm not advocating putting earthworms in your indoor pots. I was simply stating that I found them in my indoor plants and never once have I encountered any problems from them being there. Sure, I placed them in my large, outdoor pots. But that was because those pots stay outdoors year-round. The smaller earthworms found their own way into my smaller pots, while those pots were outdoors. People claim that they can't survive living in containers, but the small ones in mine seem to do just fine. Even if they were to die, their remains end up breaking down into enriched nutrients that the plants can use.

Not a Hoya at all, IMO. A succulent I would guess. Nice, though! Denise in Omaha

If I may suggest - regardless of exact ID, they would do better in different potting media. Looks like they are in original peat? Succulents need good drainage - that means pot with drainage hole(s) and fast draining mix. And lots of sun (after being acclimatized to it).

If there is growth that is discolored, dead, or no buds of any kind, prune it down to 2'. Flowers will only show up on the growth from the previous year. If you prune it every other year, it will encourage the flowers to grow more thickly. Eventually it will form a very dense hedge. It sounds like it may be in deep shade from the oak tree and ivy! Quince will flower more and produce more fruit if it has longer exposure to sunlight. If there is a very dense growth of ivy on the oak tree, trying removing as much of the ivy from the tree as you can. Ivy will eventually kill the tree, and it will block the some sunlight from reaching plants around the tree. You could also do a light dose of fertilizer to help your quince get re-established since the privet hedge and weeds have been choking it. Let us know what you decide to do, and how it goes!
