If you enjoy cooking with rhubarb, it's worth making space for a few of these plants in your garden. Although the tart flavored stalks are traditionally used like a fruit for pies, jams, and jellies, rhubarb is actually a long-lived perennial vegetable. With just a minimal amount of effort and care, an established plant will happily provide you with a crop of tasty stalks and attractive foliage for many years.
Propagation: Rhubarb is usually propagated by planting "crowns" (divisions of the roots that contain buds for new plants). If you neighbor doesn't have some extra plants to share, crowns are easy to obtain at nurseries, garden centers, or through mail order (or online) catalogs. Two to three plants will usually provide plenty of stalks for the needs of an average family.
Where to plant: If you take the time to prepare your planting site ahead of time, established plants will reward you handsomely for possibly decades into the future. Because rhubarb is a long-lived perennial, it's best to set aside a large, sunny, out-of-the-way spot in the garden where it will be free to grow without interfering with annual vegetable crops. Rhubarb is a heavy feeder and grows best when planted in fertile, well-drained soil with a pH of 6.0-6.8. Work the soil to a depth of 24 inches before setting in the crowns so roots have plenty of room to expand.
How to plant: Plant rhubarb in early spring. For each crown, dig a hole 2 feet deep and 2 feet wide. Space each hole 3 feet apart in all directions. (Some varieties are larger and may need even more space). Back-fill the hole to a depth of 12 inches with equal part soil and compost or well-rotted manure, plus 1/3 cup of 10-10-10- fertilizer.
Place one crown in each hole so that the plant buds sit 3-4 inches below the soil surface. Tamp the soil firmly around the roots, and fill the remainder of the hole with equal parts compost and topsoil. Mulch around each plant to conserve moisture and protect roots.
Feeding: Work a balanced (10-10-10) fertilizer into the top few inches of soil around the shoots at the first sign of growth each spring.
Division: Older plants can become crowded and should be divided every 4 to 5 years or when they start to exhibit spindly growth. This is best done in the early spring. Use a sharp spade to cut down through the center of the plant. Cut the roots of the removed portion into several parts, each of which should have one to three buds. Plant them as you would crowns.
Harvesting: Rhubarb plants are usually mature enough for harvesting a few stalks the second year after planting. Stalks are ready to pull when they are 12 to 18 inches long. Young stalks with the deepest red color usually have the best flavor, although some varieties produce only green-colored stalks. Harvest the stalks by twisting them off near the base (cut stems bleed and encourage disease). Rhubarb leaves should never be harvested for food as they contain high amounts of oxalic acid, which can be poisonous.
To maximize production, remove seed spikes as soon as they form to keep them from diverting nutrients from the stalks. Stop harvesting in early July to give plants time to build up food stores for next season.
This page contains the following solutions.
Rhubarb should not he harvested until the second season after planting and then only for 1 to 2 weeks. Harvesting can be increased to 1 to 2 months by the third season and after that, plants can be harvested as often as you prefer.

My husband wants to plant more rhubarb this year. However the major plant companies we usually deal with (Park Seed, Burpee, etc.) are out of the crowns. I can find rhubarb seeds many places, but not the crowns. Can anyone help me out?

Today is July 23, and just yesterday I was given some rhubarb to transplant, I have planted it in full sun, and have spaced the root out some. My question is today, just 1 day later, my rhubarb is limp looking, and I'm not sure if it is going to make it. Can you tell me if there is anything that I can do to keep it alive and growing or should I just cut down the stalk's that I do have and hope for more next year?
How do you plant and maintain Rhubarb? What kind of soil do they like? Sun or shade?

You can start rhubarb from seed, from potted plants, or from root divisions that contain one or more buds.

I need some advice regarding rhubarb. Firstly my stalks are well over 10 inches but still green, should they be red to eat? Secondly one of my bushes is seeding on top. Should I pull this bush out or just cut the top off. Thanks for your answers in advance.

Something is eating the leaves on my rhubarb, but I can't determine what it is.

What's causing my rhubarb to be stringy? What can I add to my rhubarb's soil to produce a more tender plant? Thanks.

Our rhubarb plant has "gone to seed"; do we cut this off or leave it as it is? The rhubarb was growing fine then all of a sudden it grew this huge globe shaped head on one of the stalks. It burst open and, hey presto, seeds.

I planted a rhubarb plant last year and did very little in terms of pulling stalks so as to not ruin the crown. This year, the left over leaves were soggy. I pulled them off, very easily. Now I have "dirt", but can feel maybe the crown. Should I have pulled the soggy leaves? When will I see if the rhubarb will bloom?
Do you plant the seed part of the rhubarb to make new plants, or is that bad?

I have just transplanted some rhubarb and I want to plant cucumbers in the spot where it was. I just want to make sure the rhubarb won't grow back. What sound I do?
