How To Grow Rhubarb With Kids

How to Grow Rhubarb

One of the most challenging aspects of running a school gardening program is planning and planting to coincide with a harvest before the end of the school year, or after we resume classes in the fall. There are a number of crops that grow reliably and happily in our climate, but not all of them mature in that window of time. If you are looking for a maintenance free, perennial crop that will keep growing year after year, then rhubarb is a super star school garden choice. Here are my top tips on how to grow rhubarb with kids!

Planting Rhubarb

Rhubarb can be started from seed, but just about everyone I know gets their plants from a divided plant of a friend. Rhubarb likes to be divided (which simply means a single large plant is dug up and split into 3 or 4 plants)  every 5 years or so. Divided or purchased plants can be dug into a well drained garden bed and left to do their thing. It’s best to give a new plant a year without harvesting to ensure the plant has a solid chance of survival.

Caring For Rhubarb

Rhubarb is one of the best school garden crops because it is drought tolerant and has very few problems with pests. In the fall, when school resumes, add compost or organic material to your rhubarb and that’s all there is to it!

Harvesting Rhubarb

Rhubarb is ready for harvesting when the stalks are about the length of a yellow school ruler (30cm or so). The stalks will be red when ready for harvesting. Harvesting begins around April on the west coast and continues until the end of June. It can also continue into the summer, but leaving the plant alone through the summer allows the plant to gain and store strength for the coming winter.

Simply tug at the stalk to break it away from the plant. You can use a knife to cut the stalk as well. Remove the leaves and dispose of them. The leaves of rhubarb are toxic for humans, so they are not suitable for your compost bin and children must be specifically instructed not to eat them!

At several workshops and professional development sessions with our First Nations leaders, I’ve heard talk of sustainability for the seven generations. We can take this guideline with us into sustainable school garden harvesting with children and follow the rule of seven when harvesting rhubarb. Take one stalk for every seven that are growing on the plant. This ensures the plant is not depleted of the energy it needs to survive the winter months.
