Do rhubarb plants need full sun? I have one that is in partial sun, but it comes up small. . . 3-4 small stalks and leaves for the past 3 years. What does it need?
Yes, these plants prefer sun. The following article should be of some help to you: https://www.gardeningknowhow.com/edible/vegetables/rhubarb/grow-rhubarb.htm
I have the same problem. My sister has one that is in full sun all day & is very warm where it's at. She waters moderatly too. I think if you moved it in full sun, it should fix the problem. Maybe put it in a large barrel so it doesn't take over.
I have found termites eating at the base of the Rhubarb stock. How can I kill them and not hurt the plant?
I doubt what you're seeing is termites. Sounds more like rhubarb curculio, which burrow in from top down and commonly affect these plants. Here is more info: http://www.entomology.cornell.edu/cals/entomology/extension/idl/upload/Rhubarb-Curculio.pdf
I have Rhubarb plants that are old and get quite a lot of stalks, but now leaves are getting spots and turning yellow/brown. Can you tell me why?
This is a sign that the plants have a fungus, likely black spot. Treat the plants with a fungicide and that should clear up the spots.
My rhubarb has gone to seed. Has anyone ever planted the seed pods? Have any luck with them growing? I have planted some green ones and then dried some and planted them. They are not up yet.
Although it takes about a year or two longer to grow them from seed, it is still possible. This article should help: http://www.rhubarb-central.com/rhubarb-seeds.html
However, I would recommend growing them from crowns and cutting the blooms prior to seedpod development. Here is more information: https://www.gardeningknowhow.com/edible/vegetables/rhubarb/grow-rhubarb.htm

Someone told me that it will kill or spoil my rhubarb plants if I keep harvesting it all summer. Is this true or can I go on using it?
Yes, this is true. You should stop harvesting in early summer so the plant can recover. This article can help you with your question: https://www.gardeningknowhow.com/edible/vegetables/rhubarb/harvesting-rhubarb.htm
I live in California and have finally gotten a mail order plant to flourish. It is big and beautiful. But, it isn't red yet. Do I need to let it turn red before making my first Rhubarb pie? PLMK, thanks so much. Grammie Pami
