Sticky substance on leaves and stems, most sticky on lower leaves, top ones not affected yet. Plant reasonably healthy otherwise. Soil has mold or mildew on top, though soil is dry. Will repot plant in new soil, but what is the problem and how do I deal with sticky substance, which I presume is coming from this distressed plant? Thanks.
This is a sign that the plant has a pest infestation. Often the pests that secrete honeydew (which is the sticky substance) are hard to see. It may be aphids, scale or a few other pests. Treat the plant with a pesticide and you should see the sticky substance clear up as the pests die.
I have a beautiful Heotapleurum arboricola. It has been sitting on my desk for 6+ years in front of a window. I'm wondering if I can put it outside on my deck, which gets afternoon direct sun. Can my plant deal with that? It's also getting very tall. I've read on how to prune it though I really don't understand where to cut, or what to cut. Like do I cut the MAIN stem or just the little leaf stem?
The direct sun may be a bit much for this plant, but if you could provide it with some cover or even a little shade, the plant would proabably enjoy some outdoor time. As for pruning, you can just cut off what you feel is overgrown to shape the plant as you like. These houseplants typically rebound quickly from pruning.
most arbs wont beable to handle that much direct light. you can cut plant anywhere you want and it will regrow,best done in spring when plant is in heavy growth season
Why is my beautiful Schefflera turning black and dying?
could be air conditioning if you have it,it needs to moved away from it.
My schefflera, which looks healthy, has a sticky residue on its leaves that has even coated a windowsill and the carpet underneath it. Is this a disease or a pest?
This is caused by a pest, either scale or aphids. These articles will help you:

its scale. the plant needs to be treated along with the area where its sticky. scale will attach itself to almost anything and spreads quickly to other plants
We have a schefflera that is about 12 ft tall and we wish to bring it in for the winter. Can we root the 5 ft we take off the top in water?
That is alot of plant to try to root. It likely will not take because there would be so much foliage for the plant to try to support without a decent root system for quite some time. I would recommend using the large pruning to take several smaller cuttings and trying to root those.
My Schefflera is probably 30 years old and weighs 100+ pounds in the pot. It was the healthiest ever this summer, as we bring it outside for the season, however, the rain has flooded it. We poured off as much water as possible (the pot has no holes). Now that it's back inside (November), everything is wilting. Should I attempt a re-pot? Not an easy task as big as this plant is. Should I trim off this year's growth? Everything looks deathly on it and I wonder if it can even be revived (I really didn't want to drill holes in the pot now after decades. ).
It does sound like root rot and replacing the soil in the pot will help alleviate the problem. If repotting really is not an option, you can try applying fungicide to the soil and that kill the fungus that sometimes causes root rot.
At this point, trimming back the plant would be a good idea. There is probably not enough of the roots left to support the foliage. Try cutting it back by about 1/3.
Adding drainage holes would definitely help as well.
Have aphids on dwarf Schefflera and need to get rid of them before they start munching on my other plants.
I would first wash it off. Placing the plant in the shower works well for whole plant cleaning. Then you can treat the plant with neem oil to get rid of the aphids. Here is more information on neem oil: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
