Question: When Do I Harvest Rhubarb

Rhubarb is one of the first crops of the year. Begin picking stalks as soon as they have reached their full length. To pick rhubarb, hold the stalk firmly, pull and twist. Immediately upon harvesting, use a knife to trim the leaves from the stalks and discard. The harvest season for rhubarb lasts until the end of June.

How do I know when to pick my rhubarb?

Give new rhubarb plants at least a year before harvesting for the first time. 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, look at the length. The stalks are ready to harvest when they’re between 7 and 15 inches long.

How many times a year can you harvest rhubarb?

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.

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 does my rhubarb not turn red?

Your rhubarb does not turn red because it probably has acidic tissues. 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.

What should not be planted near rhubarb?

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.

What do you do with rhubarb at the end of the season?

Allow the foliage to die back naturally in autumn, then cut away the old leaves to expose the growing points to winter cold. There is no harm in adding these leaves to the compost heap, as the poisonous oxalic acid contained in them breaks down during decomposition.

How do you prepare rhubarb for winter?

Just keep any mulch away from the crown of the plant, which can encourage rot. To prepare your plant for winter, after the first hard frost, cut back any remaining stalks and dress with a light 2 inch layer of compost, leaves, or hay to protect the roots through the winter.
