I live in Sorrento- WA , soil is very sandy .I built up with good potting mix & it's in a semi ,parts of the year spot.I have used good fertiliser but I can't seem to get it to grow wider than my little finger , I keep chopping it back as well ,thinking it will get thicker . It was cut from a friend's crop. Need your help .

Try adding manures and compost. Potting mix doesn't have a lot of nutrients in it.

I planted rhubarb around 7 months ago, the leaves have grow huge and some are mottled and unhealthy. I know I am not supposed to harvest for the first how do I treat the plant? Do I just leave it be, or do I need to trim it or remove leaves? Does the same stalk stay until harvest time? Please advise care of plant in first year of growing until harvesting time. Thank you so much! Warmest regards

If unhealthy pull them off. Look up a natural spray for leafy veggies.

I live in south central Tennessee and want to grow rhubarb. Can I do so as a perennial or do I have to treat it as an annual? And where is the best place to plant the crowns?
