I have one Rhubarb plant and it finally has stalks. I read that the first year I should not pick. I believe I need to move it so it can get more sun. When is a good time to relocate the plant? If I do not cut any of the stalks, is that all I do and will they just shrivel up and come back next year? Please help
Early spring before new growth appears, or fall will be best for transplanting. Wait until the first year's stalks die and shrivel, then remove them. https://www.gardeningknowhow.com/edible/vegetables/rhubarb/protecting-rhubarb-in-winter.htm
This is the second year for my container grown Rhubarb here in North Texas. The plant grew back nicely this year however the stalks still resemble small/thin celery and they've never turned Red. Do I need to wait another year before expecting to be able to harvest it?
They should mature in their second year. You can harvest sparingly up until fall. Here is more info:

I have been battling Red Spot Fungus on my rhubarb all summer, with a Fungicide. It is better, but not gone. I have NOT composted any of the leaves. Will it come back again next year. (This is the first time in 7 years). What can I do now to prevent it's return in the Spring?
It will, likely, carry over from season to season.
There are a few things that you can to do manage the illness, though. This article will help:

Rhubarb leaves are poisonous, but the fruit of rhubarb plant is delicious when sweetened. Rhubarb does need to be grown in an area where the temperatures drop below 40 degrees in the winter. Winter dormancy is important for its health and growth. Here's an article about rhubarb:

Hello, I just read your article on planting rhubarb in the Southern Hemisphere, but still have som questions. Can I grow seeds now? Or do I need to wait? The seeds has been in the fridge for a couple of weeks, but I read that it needs 6 week in cold temperature. Together with which other plants will they thrive?
Since most of Indonesia is warm year round, you will grow rhubarb as an annual. It is a cool weather crop that does well with strawberries. Plant seeds in summer to early fall. Since seeds take two years to mature, you may want to grow your rhubarb from crowns or divisions purchased at a garden center.

Should it be the other way round?
I realize this article uses the word "spindly," but I think it will apply to your plants, as well. Rhubarb leaves can get huge. There are a few considerations. Perhaps they need a longer time to grow before harvest, but in this article, you will see that there can be other factors:
