My rhubarb, planted 2 years ago in zone 5, keeps developing flowers (with seeds?).  I would love direction as to what to do when this happens, is it supposed to happen, why does it happen. Thank you!

Dawn, it is normal for a plant to flower and go to seed. It is trying its best to reproduce. There is nothing wrong with your plant flowering. There are several reasons why it may be flowering (or bolting). Age, heat, stress or the variety. Some things that you can do that might help to reduce stress is mulch heavily around the plant to help keep the roots cool, keeping it watered, fertilize and make sure it is disease and pest free. If your rhubarb is old (which yours is not), it helps to divide it. If you have an unusual warm spring, that may send it into flower.

Hi Suzanne, Thank you for your quick and helpful response. Another question please:  Hopefully we were to cut off the seed parts (there were 3-4 of them) as we did this weekend. We will heavily mulch and add more water (it’s mostly dry here in NE Kansas, hot in summers and usually always very windy!). Thanks for your help!  Dawn

I bought two crowns last year and planted them where I thought I wanted them… turns out I really need to plant them in a different location. Can I do that this Spring? Or, should I wait one more year till they’re better established.

Karen, you should dig them up and move them during the dormant season. Not sure where you live, but if you live in a mild climate area, spring may be too late to transplant them. It is really up to you if you leave them in one more year. But after you move them, do not harvest from them until the following year.

Jennifer, rhubarb can be split or divided during the dormant season and is really easy to do. Remove all spent stalks and leaves from the existing crown. Dig up the whole crown (dig far enough away that you don’t damage the clump). You can use a large knife, a hori hori or even a hand saw to cut up the crown. Make sure you have at least one growing tip per section. Dig a new hole and supplement with some good compost, plant the crown at or just above the level of the soil (basically the same level as it was before). Come spring and summer, do not harvest any of the stems, let it grow and establish itself. The second year you can start harvesting (maybe not all at once).
