I have nice leaves on my beet plants, about a foot high, but when I pick them, there is no beet. . . only a very small root.
Sounds like the beets may not be mature or ready for harvest. They can be grown throughout fall/winter in warmer areas. You may need to allow more time to pass and then check the plants again to see if they have reached the desired size. The following article may be of some help: https://www.gardeningknowhow.com/edible/vegetables/beets/growing-beets.htm
Additionally, adding some phosphorus-rich fertilizer will help with root development.
I have tried growing beet root in flower troughs, but the leaves became very discolored (the vegetable itself was, however, very tasty). I am now growing a second crop, but the leaves are again looking horrible (in a new trough). Any hints?
It sounds like chlorosis, which is an iron deficiency, either caused by too little iron or too little nitrogen (which prevents iron uptake). Here is more information on that problem and how to fix it: https://www.gardeningknowhow.com/plant-problems/environmental/leaf-chlorosis-and-iron.htm

What's the best way of storing beetroot?
Believe it or not, storing in sand is best for beets. Remove the greens (leaving about an inch of stems) and place the beets in a container of slightly damp play sand. Store the container in a cool place.
Can beets take cold weather?

I have tried this with some success.
Any plant can technically be transplanted, but with short lived root vegetable annuals like carrots and beets, the time it would take for the plant to recover from the damage is often as long as it would be to replant new seeds and grown them. Because of this, people often do not transplant them.

How close can I plant beet seeds to cabbage seedlings?
Beets and cabbage make wonderful companions in the garden. To ensure that these plants have plenty of room while growing, I would space them at least a foot from one another, if not more depending on the number of plants and available space.
