The best time to harvest rhubarb is during the months of May, June and early July. After this, it’s best to let the plant be, so it can regrow and recharge to survive the winter. You can cut the flower stalk away before it blooms to help extend the harvesting season.
When should you not pick rhubarb?
A good rule of thumb is to pick your rhubarb no later than July 4. The harvesting period typically lasts about 8 to 10 weeks. Rhubarb plants are dormant during the fall and winter. If you try to harvest your rhubarb too late, the stalks might get frost damage and be inedible.
How can you tell if rhubarb is ripe?
When you’re looking at the stalks, the color doesn’t indicate readiness, so don’t worry if your rhubarb stalks are not completely red. Instead, check the length. The stalks are ready when they’re between seven and 15 inches long. The best time to harvest rhubarb is during May, June and early July.
Should you cut rhubarb or pull it out?
Harvest rhubarb by cutting or gently pulling the stalk away from the plant. Do not harvest any stalks during the first growing season, so your plants can become established. At this point, their harvest period should run 8 to 10 weeks or until the stalks become thin, which may be a sign that food reserves are low.
Why do you pick rhubarb at night?
For those who haven’t yet had the pleasure, home-grown rhubarb is quite delicious and it’s those stems grown in darkness that are the most desirable of all. Growing plants in the dark, often with the addition of a little warmth, is known as ‘forcing’. It’s a simple way of tricking nature into early growth.
Can you pick rhubarb all summer?
Continued harvest through the summer months weakens the rhubarb plants and reduces the yield and quality of next year’s crop. The stalks will likely be a little tougher than those harvested in spring, but they are not poisonous. Plant vigor is the reason that rhubarb should not be harvested in summer.
Should I cut back rhubarb for winter?
Prune back the rhubarb stalks to the ground in late fall or early winter after they begin to die back naturally from frost. Rhubarb may not die back completely if temperatures remain above 40 degrees Fahrenheit, but dead and damaged leaves can still be removed throughout winter, cutting them with shears or a knife.
Why is my rhubarb green and not red?
At the season’s end, when the rhubarb starts dying down, each piece that is falling to the ground will carry acidity in it. With time, acidity from the pieces that are composted to the soil reduces the surrounding soil’s pH. Due to this, the red color leaves the plant and you are left with only green stems.
Can you eat rhubarb leaves?
Rhubarb leaves are toxic and humans should never ingest them. According to the U.S. National Library of Medicine at the National Institutes of Health symptoms can include: Breathing difficulty. Burning in the mouth.
What do you do with rhubarb at the end of the season?
The harvest season for rhubarb lasts until the end of June. Until then, pick as many stalks as you wish. After harvest, allow the plant to keep all of its leaves, to build its reserves of energy for the next year. A common myth is that the entire plant becomes toxic later in the summer.
How do you pick rhubarb so it keeps growing?
There are two ways how to harvest rhubarb. One is to use a sharp knife or shears to cut off stalks that are at least 10 inches (25 cm.) or longer. The second is to gently pull the stalk while gently leaning it to one side until the stalk breaks off from the plant. Never harvest all the stalks off your rhubarb plant.
How do you winterize rhubarb plants?
Dig up the crowns in late fall and put them in a pot. Let them stay outside during at least two freeze periods. Then move the crowns inside where the crown will warm up. Put the pots in a dark area and cover the crowns with peat or sawdust.
How toxic is rhubarb leaves?
In general, however, rhubarb leaves don’t pose much of a threat. Since a lethal dose of oxalic acid is somewhere between 15 and 30 grams, you’d have to eat several pounds of rhubarb leaves at a sitting to reach a toxic oxalic acid level, which is a lot more rhubarb leaves than most people care to consume.
Why do you put a bucket over rhubarb?
Forcing rhubarb – covering the crowns to prevent light reaching them – will encourage the plants to make early growth. These pale, forced stalks can be harvested for use in cooking when they are 20-30cm long and are a useful crop when there is little else in store from the garden.
Does rhubarb need light to grow?
Site and soil Rhubarb needs to planted in full sun but will tolerate partial shade in a warm garden. I would advise a spot with at least 6 hours of sunshine per day so keep an eye on the garden for a few days to find the best spot to plant.

What do I feed rhubarb?
Feeding in Spring and Autumn with a long lasting organic fertiliser such as blood, fish and bone or bonemeal (two good handfuls sprinkled around each plant) will be sufficient. If you have any well rotted manure then spread a layer around the plant but far enough away so as not to touch any emerging stalks.
Should rhubarb be red or green?
Green rhubarb will always be green. The only sure way to get red stems on your rhubarb is by purchasing dormant crowns of a good quality, properly named, red stemmed variety. It’s not that green stems aren’t edible.
Does rhubarb spread on its own?
They will spread and fill in open spaces. The plants tolerate a little crowding, but the stalks and leaves will grow bigger and healthier if you allow them plenty of space. A few plants are all you will need for a home garden. If you are planting large quantities, space rows three feet apart.
