Ugh, mites, yeah, it gets them now and again and I just keep spraying for them. My smaller crotons have a harder time dealing with them, I really wish I could wipe the mites out completely, but nothing has worked so far. I've just decided to live with it and spray whenever I think of it. :) I like how this plant is doing, just the color change threw me off, and the leaf size impressed me. I've noticed a lot of houseplants tend to get bigger leaves the taller they are (like pothos' when they're climbing high vs crawling), maybe it's the height having some effect. Five more years though and this thing will be hitting the ceiling :P Now if I could get this one to flower once again, that'd be awesome.. been a couple years now. Several of my other crotons are flowering, got some fruit even and maybe seeds. Who knows what wonders may grow :)

Move the lavender! Wormwood gets to about 1 metre high but can spread several metres. It has a reputation as a bad companion because it inhibits the growth of other plants nearby. Yours is a lovely specimen!

This is mine. I've taken off a bunch of pups. Some I grafted onto a native opuntia, one onto a peanut cactus, one onto a piece of dragon fruit, and one onto another type of opuntia - the spineless variegated variety. 6 more pups are callousing over to be planted on their own. Some of the pups are almost an inch in diameter. I only took the really big pups off. Question: will the momma plant make more pups? It seems like every aerole had a pup - is that a one-time thing or can the same spot produce more pups?

As to the fertilizer, I can only suggest you contact the manufacturer, since I don't know what they put in it and what concentrations. Generally if an amaryllis is grown with some food, some water, and enough light to make food, it flowers...unfailingly. Something in your cultivation is evidently wrong. Most people do not use soils these days, but use a mix that probably doesn't contain soil or maybe not even sand ;) Though, certainly they can be grown in almost any media with the proper care. I suggest putting them outside for the spring, summer, fall, and only house planting them when the weather requires :0 that will give them the best chance. No plant evolved to be a full time houseplant, they simply tolerate it.
