How do rhubarb grow

Rhubarb is easy to grow, but needs a dormancy period to really thrive and produce an abundance of huge stalks. The stalks are the only edible part of the rhubarb plant. These have a rich, tart flavor when cooked.

The leaves of the rhubarb plant are toxic—they contain an irritant called oxalic acid—so be sure that they are not ingested.

For that reason, rhubarb should be planted in its own space in any corner of the garden where it can grow undisturbed. Rhubarb grows well in soil amended with plenty of well-rotted manure or compost; this has inspired some gardeners to just go ahead and plant it near their compost piles! With its ruby stems and umbrella-like leaves, rhubarb also adds height and structure to your garden along with a splash of gorgeous colour that will return year in year out.

Rhubarb can be grown from seed, but this is not recommended. It takes several years for rhubarb plants to be mature enough to produce a good harvest. Rhubarb has many other uses, from medicinal to cosmetic.

I inherited the roots about 15 years ago it when my aging father wanted to close down his gardening. The roots originally came from my grandparents place mother's side , split off from their stock that they had been keeping going since the mid 's!!

I have no idea what variety it is but I guess it would be considered 'heirloom"! I always know spring is here when I notice the rhubarb budding up from the ground. It does well in the raised bed but does need some manure top dressing this year. I decided to establish my rhubarb in a raised bed to keep weeds at bay. I remembered the difficulty of weeding the ground level bed my dad had them in. They were at the edge of the garden and lawn, grass was always invading the rhubarb, and it made for quite a chore to clean it out.

My raised bed has been successful at minimizing weeds. Every year it provides all the rhubarb I need and can share. Once I have harvested all I want I leave the plants to grow and feed the root. I only have to cut off the flower stalks and pluck leaves as they age and are replaced by new ones. Also, I have heard that rhubarb leaves can be used to make a "tea" extracting the acids and toxins to make a natural pesticide. Does anyone else have any insight into making or using that?

Boil for 10 to 15 minutes, then strain the liquid through a cloth or fine strainer. Reheat the tea liquid and add a cinnamon stick. Let it simmer a few minutes and then steep briefly.

Sweeten as desired, after tasting. I live is Michigan. I planted 4 new rhubarb crowns from a company in MASS. I planted them 5ft apart in mounds in a sunny location. All 4 came up and looked nice but lately each plant started to get yellow on the outer large leaves. Our garden is new and pretty sandy. We added compost in the spring. Do you have any ideas? Hi I planted three crowns this year my rhubarb seems to have taken but the leave are full of holes is this okay or should I put down some slug pellets.

Amanda, if you haven't already done so, cut the flower stalk off. It will only sap energy from the plant that you want to go to the stems and roots. You may also want to think about dividing the plants since I assume your mother's patch has been around a while.

Lots of good on line advice about that. Good luck with the rhubarb! She always grew and harvested the rhubarb so this is all new to me. What do I do with this stalk?

Leave it? Cut it? Hi--I ordered 2 rhubarb crowns from a seller on Etsy and they have arrived alive. But they are very small. Should I plant these in containers and keep them in my unheated basement near a sunny window for the winter OR should I go ahead and plant them in the prepared raised bed. I live in NC, growing zone 7b. Thanks for any advice! That is remarkably small. Our research suggests that zone 7b is right on the line of survivability and success, so rather than recommend any particular care, call the coop extension.

Can rhubarb still be harvested in Sept? I had heard to only harvest in months with no "R". A soil-based compost, such as John Innes No 3. While clay or terracotta pots are traditional and are specifically designed for this purpose , an upturned dustbin or a large bucket will work equally well. In January, cover the crown with a layer of straw and then place your choice of large container over the crown to exclude the light. Forced rhubarb stems can be harvested around eight weeks after covering, which may be up to a month earlier than unforced crops.

However, try to avoid forcing the same rhubarb crown for two years in a row; this can weaken the plant. Our top tip? Grow several rhubarb plants at a time and force just one a year in rotation. Rhubarb plants are very low maintenance, but they will produce better crops if given a little extra care and attention according to the season. During the first year, you need to resist the temptation to harvest the stems, in order to allow your rhubarb plants to become properly established.

But your patience will pay off because, from the second year onwards, your rhubarb can be harvested from April to June, when the leaves have fully unfurled and the stems are 30cm long.

To harvest, pull each rhubarb stalk from the base of the stem and twist it away from the crown. Don't worry if you find that you have more rhubarb than you can use; rhubarb freezes really well. Pickling and preserving is also a great way to extend the shelflife of your rhubarb. A word of warning: only the stems of rhubarb are edible.

The leaves contain oxalic acid, which is toxic if eaten. Simply trim the leaves away from the stems and add them to your compost heap. Crown rot can be a problem when growing rhubarb. The best thing to do is act quickly and cut away any affected areas of the plant.

How to Grow Rhubarb The ultimate guide to growing rhubarb in the UK Image: Shutterstock What could be better than rounding off your Sunday lunch with a piping hot bowl of rhubarb crumble? Which variety to choose Different varieties have different flavours, strengths, and qualities. There are many ways to control slugs and snails, including beer traps, sawdust or eggshell barriers, copper tape and biocontrols.

The following year, pick just a few stems. After that, the plant should be well established and can be harvested normally.

On established plants, stalks can be picked from March or April onwards for early cultivars, and late April or May onwards for maincrop varieties. Only ever take about a third of the plant's stems, so there are plenty left to keep it in active growth. Earlier harvests of sweeter, tender, pale stems can be produced by covering rhubarb plants with a forcing jar or bin in late winter, so the stalks form in the dark.

They can be ready to harvest as early as March, several weeks before plants left to grow normally.
