Rhubarb-Harvest done in a timely fashion will ensure a top rhubarb-season next year.
It is time for harvesting the rhubarb, but if this is only the
end of the first season, please wait if you can. Towards the end of the
second season is much better, and the third year will be tremendous.
The rhubarb plants require time and as much of their foliage as possible
to establish a strong healthy root system. Picking can take place
towards the end of the second season actually. So, be patient.
When the time is right, the picking can start anytime in early
June or even earlier for some people. It can last right through into
the month of August.
Long thick green rhubarb-petioles are just as good as the thinner red ones. The
red stalks will be much sweeter. Medium stalks are generally very tender.
Not to worry. They all provide good eating.
When you are ready, simply reach down to the lowest part of the petiole
and give it a good pull. I have never encountered any problems. The stalks
seem to snap off from the crown fairly easily.
Do not pick too much from any one plant at a time. Move on to another clump.
Alternate what you pick over the course of the season. The longer each
clump can hold on to the foliage, the better chance it has to keep producing.
Just a reminder....if at any time over the course of the season you see a
large stalk which looks like it is flowering as in the picture below, cut it off at the base. This
helps to redirect all energy resources available back into the root system
and strengthen them.
To complete your rhubarb-harvest cycle, you must cut off all of
the leaves and throw them away. In all varieties of rhubarb, the green leaves
are toxic. They contain a substance called oxalic acid crystals which could
cause swelling of the tongue and throat.
THE PETIOLES ONLY ARE EDIBLE BUT THE LEAVES ARE NEVER EVER TO BE INGESTED!
The leaves can safely be thrown into your compost pile. The toxic acid has no
effect on compost, so do not be concerned. While on this subject of how to harvest, it's good to note that you should wear gloves when
handling the rhubarb at any time. You would not want children
or animals near the leaves either. Better to be cautious!!
Just before you protect your rhubarb for the winter, now
would be a good time for
rhubarb propagation
to have even more clumps for next year. This can be done
in the Spring or the Fall, whichever time suits you best.
