Rhubarb Seed

Filed under: fruit — Tags: , — TopVeg @ 3:32 pm

We left a flower of rhubarb on the plant in the vegetable garden so that it could develop into a head of seed.

 The usual way to get a new rhubarb plant is to replant a piece cut off the crown (or root).  It will take a long time to establish a useful rhubarb plant from a seed.

Rhubarb colour

Filed under: fruit — Tags: , — TopVeg @ 8:22 pm

 The colour of Rhubarb sticks is determined by:

  • variety – later varieties hold their colour longer
  • growth rate – in Spring the rhubarb stick grows slowly so the colour is retained further along its length of stick. Later as the season warms up, the stick grows faster and the colour disappears, turning the stick green.

An exception is Cawood Delight, a late variety harvesting from late May, which keeps a fantastic dep red stick.

What to do when rhubarb flowers

Filed under: fruit — Tags: , — TopVeg @ 6:25 am

Rhubarb flowers should be removed as soon as they are seen.

  • Hold the flowering-stalk close to the ground
  • Pull upwards twisting the stalk
  • Remove the flowering stalk to the compost heap

If the rhubarb flower is left on the plant,  the root will be weakened & the stalks will be weak and thin.

Rhubarb Flower

Rhubarb (Latin name – Rheum rhabarbarum) often sends up flowering shoots at this time of the year.

If the rhubarb flower is left on the plant,  the root will be weakened & the stalks will be weak and thin.

So, the rhubarb flowers should be removed as soon as they are seen.

  • Hold the flowering-stalk close to the ground
  • Pull upwards twisting the stalk

The tendency to bolting depends on:

  • variety – Victoria is more prone to flowering than other varieties
  • maturity – older plants are more likely to flower than younger ones
  • weather – prolonged high temperatures and drought promote flowering
  • nutrition – lack of nutrients makes the plant want to seed

To encourage leaf growth and discourage flowering of rhubarb:

* divide the crowns every 4-5 years to keep them young
* water during the harvesting period if in drought conditions
* feed with well rotted manure or fertiliser in early spring and autumn
* do not totally strip the root – always leave 4 or 5 stalks.
* stop pulling stalks after July, to allow the leaves to feed the root
* do not force each crown more than once every two years
* provide an open, sunny site in the vegetable garden

Although the rhubarb flower may add charm to the vegetable garden, it is not good for the production of rhubarb to eat.

Time to Divide or Move Rhubarb

Filed under: fruit — Tags: , , , — TopVeg @ 2:06 pm

The time to divide or move rhubarb is in the autumn or spring.

  • dig up the crowns (the fleshy rhizomes and buds)

  • discard old or damaged parts of the crown
  • use healthy bits of crown with 2-3 good buds on them

  • prepare the ground with plenty of well rotted farmyard manure or compost ( rhubarb is very greedy)
  • mulch the rhubarb crowns once planted
  • be gentle with the young rhubarb plants in the first year, better not to force them, or to pull too many stalks
  • therefore best to lift & divide a small section of the rhubarb bed each year, so there are always some older plants to force and use.

This book from Amazon has some good rhubarb recipes!

Now is a good time to divide or move rhubarb, but if time is short, spring will do.

Rhubarb

Filed under: fruit — Tags: — TopVeg @ 6:55 am

Rhubarb produces a large crop from a small space. Now is the time to harvest the long tender shoots.

Any surplus is very easy to freeze, by chopping it up, placing it in a labelled bag and freezing it immediatley.

The first rhubarb is always best stewed. Follow these instructions from FarmingFriends

Rhubarb in the Vegetable Garden

So glad Freddie of the GreatBigVegetableChallenge likes rhubarb, and has been eating it straight from the vegetable garden.

We went to Wakefield to see the rhubarb sheds, which are surrounded by
huge water pipes carrying hot water to keep the sheds warm. Small
fireplaces in each shed glow as they heat the water for the heating pipes.

But the most amazing thing was seeing the stocky Yorkshire-men carrying
small candles into the shed to pick the rhubarb stalks. Only very small
flames are allowed, because the tender, pink stalks need absolute
darkness! The roofs are low, and there is a strange silence in the sheds.

For more information on rhubarb see:

* forcing rhubarb

* freezing rhubarb
* flowering rhubarb
* how long to pick rhubarb

 

Rhubarb crumble is the ultimate reward for growing rhubarb in the
vegetable garden.

How Long to Pick Rhubarb?

Filed under: fruit — Tags: — TopVeg @ 1:55 pm

Rhubarb is really a spring crop. When the stalks are no longer fat and
juicy, but grow as thin stalks, the time has come to give it a rest.

Rhubarb can be pulled all summer if it is growing vigorously, and if at
least 25% of the stalks are left on the plant.

The rhubarb plant should be kept weed free, so that it can grow and feed
its roots. All damaged and discoloured leaves should be removed with
their stalks.

In the autumn, rhubarb appreciates a good covering of well rotted farm
yard manure.

Flowering Rhubarb

Filed under: fruit — Tags: — TopVeg @ 6:17 am

Rhubarb (Latin name – Rheum rhabarbarum) often sends up flowering shoots at this time
of the year.

 

rhubarb-flower

The rhubarb flowers should be removed as soon as they are seen. Hold the
flowering-stalk close to the ground, and then pull upwards twisting the
stalk. If left, the flower will weaken the root, which will then produce
weak thin stalks.

The tendency to bolting depends on:

    * the rhubarb variety – Victoria is more prone to flowering than
      other varieties
    * maturity – older plants are more likely to flower than younger ones
    * weather – prolonged high temperatures and drought promote flowering
    * poor nutrition

To encourage leaf growth and discourage flowering of rhubarb:

    * divide the crowns every 4-5 years to keep them young
    * water during the harvesting period if in drought conditions
    * feed with well rotted manure or fertiliser in early spring and autumn
    * do not totally strip the root – always leave 4 or 5 stalks.
    * stop pulling stalks after July, to allow the leaves to feed the root
    * do not force  each crown more than once every two years
    * provide an open, sunny site in the vegetable garden

Force rhubarb

Filed under: fruit — Tags: — TopVeg @ 7:00 pm

* The rhubarb is ready to produce shoots.
* Force it up, by creating a dark environment.
* Cover it with a chimneypot, dustbin, or straw.
