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?

From what I read, give it a good spot for it to get sun during fall-spring and protect it from heat(shade it) during summer. It's delicate to heat. I'm going to try planting mine on north fence and then planting sunflowers for shade but giving it good ventilation in between. We made need shade cloth.

I am growing Victoria rhubarb in three-gallon nursery pots in North Georgia. I started the plants (small roots) this spring in a sunny area during cool weather, but moved them into partial to full shade as the heat increased. The soil in the pots is a loamy sand mixed half and half with compost. I water daily, about a quart of water per plant. I top dress each pot with about a teaspoon of granular 13-13-13 fertilizer whenever I notice growth slowing down, roughly once a month.. So far, it has handled temperatures up to 95 F with no problems. My plants are huge, about 3.5 feet across with long thick stems. One thing I have noticed! is the stems are mostly green, not red, this could be due to the shade, or possibly heat. They still taste great in strawberry rhubarb pie, though I'm harvesting very little this first year, hoping for the plants being larger and stronger next year. As a precaution against disease, any leaves and stems that are starting to yellow with age I pull off of the plant and compost them.

What variety of rhubarb will grow in zone 8 or 9

We grow Glaskins Perpetual Rhubarb and Victoria and they both do very well here in Eastern NC.

My Month by Month Florida Gardening book says you can grow rhubarb year-round in north Florida and August to October in central and south Florida. I’m guessing shade cloth would be in order for the latter two the rest of the year. I never cared much for it growing up in Iowa but I think I’ll give it a try at my little hobby farm near Arcadia, Fl just for the challenge of it.

If you can plant them either in big pots or in dappled sun/part shade it may be helpful but I don't think shade cloth would help as much as drip irrigation may. Best of luck!

The plants probably need more regular watering than shade cloth. Heavy shade cloth will reduce the available sunlight. By this guide not a lot of opportunity to grow it in zones 6a or 6b. I have absolutely no idea what your weather is like - I live in Australia.

Most plants need lots of sunlight. Check what Climate Zone San Diego is in the climate zone section here and look it up if you can grow it.
