My oxalis is having difficulty. As you can see in the photo, there are only two stems with leaves on them. When I inherited the little guy, there were about 5-7 leaves on it. Maybe you can give me some tips so I can save him. I was looking at some of your fertilizer ideas. I have fish/kelp 4-6-6 fertilizer but I have not used it yet. What is meant by 'needs a time of darkness to rest'? I hope you can help me so I can help this little guy. Thank you.

They go dormant in winter, or even as early as late summer in hot areas. They need a period of dormancy where it is mostly dry (only a few drops of water per week) and cooler. Darkness helps to keep it from sprouting at inopportune times.
Without a dormancy each year, they will start to lose vigor and slowly die off completely. This article will help you to know how long the dormancy should last, and how to care for the plant: https://www.gardeningknowhow.com/houseplants/shamrock/growing-shamrock-plants.htm
