Rhubarb Picking

It’s time to harvest rhubarb!  I can’t wait for the first rhubarb crisp of the season.

Here are some rhubarb harvesting tips:

  • Stalks should be about 10 to 20 inches long.  Size is a much better indicator of readiness than colour since some varieties will never turn completely red.  They’re suppose to be green with a little bit of red on the bottom – so don’t wait for them to turn red!
  • Start with the bigger stalks on the outside of the plant and work your way towards the centre.  Leave the smaller stalks for another day.
  • Leave 1/3 of the stalks to ensure the plant continues to grow and thrive throughout the summer.
  • Simply slide your hand to the bottom of the stalk and pull.  The stalk should come out nice and easy.
  • If you find you’re pulling out roots or you can’t reach, you can also cut the stalks at the bottom.
  • Trim the leaves and put them in the compost. (Yes, the leaves are poisonous, but they won’t hurt your compost bin.)
  • Once the plant starts to flower, the stalks will get a little tough.  To extend the season, cut off the flower stalks.
  • Towards the end of June, give the plant a chance to gain some strength over the summer.  Add a little compost around the roots and let it be.
  • Rhubarb doesn’t like the heat and won’t do much during the summer, but you may get some more stalks in the cool fall season.

Concerned that your neighbour’s rhubarb plant is bigger than yours?   To get a big luscious rhubarb plant think about moisture, drainage, compost and sun.  These are the elements that will make a rhubarb plant thrive.  But, luckily, even if conditions aren’t ideal, rhubarb is very tolerant plant and you’re bound to get  a pie or two.

Here’s some pictures of rhubarb plants to help you see the different stages.

Of course, if you have too much rhubarb, don’t like rhubarb or know of anyone who isn’t picking their rhubarb – call us!  We have eager volunteers ready to pick rhubarb to share with their families and with local food charities.

Top 5 Questions about Rhubarb

Here are the top 5 questions we hear about rhubarb and some links to all things rhubarb.

1. Are rhubarb leaves really poisonous?
Yes, rhubarb leaves are really poisonous.  High levels of oxalates and anthraquinone glycosides that are present in rhubarb leaves are believed to be the culprits.  Check out  The Rhubarb Compendium for more information.
Having confirmed that the leaves are poisonous, let’s keep things in perspective.  You would need to eat about 5 kg or 11 lbs of rhubarb leaves to cause death.  That’s a lot of rhubarb leaves!  Of course, you’d need much less to get a tummy ache. 

In other words, don’t make rhubarb leaf salad for dinner tonight!

2.  Can I put rhubarb leaves in my compost?
Yes, you can compost rhubarb leaves.  Since we don’t eat our compost pile, there is no danger to us.  And, because the components break down so quickly, there’s no danger to the microbes in your compost bin either.  Even when you finally use your compost, the acids will have been decomposed and won’t affect the acidity of your compost.
3.  How do I know when rhubarb is ready to harvest?
Despite what someone may have told you, do not wait until the stalks turn red!  You might be waiting for a long time since not all rhubarb varieties will ever turn completely red.  Instead, rely on the size of your rhubarb.  Start harvesting when stems are about 25 to 40 cm or 10 to 15 inches long.  Check out Purdue University for some more information on rhubarb harvesting.

4.  What’s the proper way to harvest rhubarb?
Our best advice is to pull out the large stalks on the outside of the plant.  Run your hand down the stem until you’re close to the ground then gently pull with a little twist.  The stem should come right out.  Leave at least four or more stems in the middle to ensure further growth.
5.  How much rhubarb in a…?
Here’s our rhubarb conversion chart.  It comes in handy when making all those delicious recipes!
In Metric Measurement
1 bunch = 5-8 stems
5-8 stems = 2.2kg
2.2 kg diced into 1 cm pieces = 875 ml 
In Imperial Measurement
1 bunch = 5-8 stems
5-8 stems = 1 lb
1lb diced into 1/2″ pieces = 3 1/2 cups
