Question: 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 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 do you know if rhubarb is Woody?

Typically, the woody section on a stalk of rhubarb will be paler in color, if not white, and can easily be removed with a knife. A general rule of thumb with rhubarb is to remove the bottom inch of each stalk, and then more if a stalk still has a white section present.

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.

Why is my rhubarb not 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.

Is it better to cut or pull rhubarb?

When stalks are sliced with a knife, the part left behind withers away… and that’s it. In contrast, twisting and pulling off the stalk allows it to separate from the bottom of the plant near the roots. This tells the plant to regrow a new stalk, giving you a more fruitful harvest and a healthier rhubarb plant.

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 shouldn’t you pick rhubarb after July?

It is generally recommended that home gardeners stop harvesting rhubarb in early to mid-June. Continued harvest through the summer months would weaken the plants and reduce the yield and quality of next year’s crop. The rhubarb stalks may become somewhat woody by mid-summer, but they don’t become poisonous.

Should I remove yellow leaves from rhubarb?

Yellowing and wilting leaves could simply be a lack of water at crucial times. Then again, the soft stalks may also point to a fungal disease. Check the base of the crown for white fungal growth or rot spots. Affected plants should be completely removed, disposed of in the garbage, and replaced with new plants.

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 know if rhubarb has gone bad?

When it comes to sure signs that you should discard your rhubarb, look for: Mushiness. Rhubarb is very firm. Large black or brown spots. Mold. If there’s quite a lot of mold on the stalk (and not only a minuscule amount like on the photos above), discard it. Off smell. If it smells off, there’s something wrong with it.

How toxic is rhubarb leaves?

In general, however, rhubarb leaves don’t pose much of a threat.
