Last week I sprayed my indoor plants (Clivia, Aloe, Walking stick succulent) with the combination treatment of water, dishwashing liquid and oil in order to get rid of the few aphids I found (brought in by a gift of an African violet). There has been no trace of aphids since, but the liquid formula is still on the leaves of the Clivia, a very large plant by now. Should I do anything -- such as washing the formula off the leaves or leaving the oil and liquid on the plants?
It should not hurt the plant, but if it is unsightly, you can wash it off. Placing the plant in the shower works well for whole plant cleaning.
After the blooms have dropped, when is the best time to cut back the flower stem?
You can prune the stalks anytime after flowering. The entire plant can be cut back in spring prior to any new growth.
How can I take care of a Clivia plant?

I have had two of these plants for almost 3 years. They are growing. I was told they would produce very fragrant flowers after the third year. The plant has approximately 10 leaves about 12" long and about 2" wide. I am not sure that the name of the plant is spelled right, but I am hoping you can help. Thank you.
Yes, they are called clivia.
Clivia need a rest period in order to bloom. They are alot like amaryllis in this regard. Have you provided a rest period? This article will help you with doing that:
House plant was in very good condition until yesterday and is now cover with white spots. I don't know what they are. Indoor plant not in full sun, always in the same place. Help!
It is probably mealy bugs. This article will help: https://www.gardeningknowhow.com/plant-problems/pests/mealybugs-white-residue-on-plants-leaves.htm
What do I do with the hips that are left after the blossom dies? Also, mine is planted in a shady area outdoors (not in a pot). How do I get it to re-bloom? I'm in northern. CA and there are many clivias in the area planted outdoors.
Most people remove the seed pods, simply because they divert energy from the plant's next bloom towards producing seeds. If you do not want or need seeds, just cut the pod off.
With the plant being planted outdoors, you should not need any special care for them to rebloom. They will go into a dormant period all on their own and will rebloom for you next year.
I have one Clivia that is covered with caterpillars. I have trimmed it right down and have sprayed it with the Margaret Rose mixture. Do I need to spray again and, if so, how often? Do I need to add any form of fertiliser? The other Clivias do not have any caterpillars, but I will keep an eye on them.
I would spray about once a week for one month just to make sure you clear the pests out. I would not fertilize until you see the plant putting out new growth. Stressed plants can be easily burned by fertilizer, so it is best to wait for it to recover before doing that.
