When stalks are sliced with a knife, the part left behind withers is gone. 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 grow a new plant, which will give you a more fruitful harvest and a healthier plant.

Should you cut or pull rhubarb?
Harvest rhubarb by cutting or gently pulling the stalk away from the plant. Plants can become established if you don’t harvest stalks during the first growing season. When the stalks are 12 to 18 inches (30 to 40 cm) long, begin harvesting your Rhubarb the year after planting. When you are ready to harvest, cut off the top 1/4 inch (1.5 cm), leaving the rest of the stem attached to the rhizome.
You can use a sharp knife to cut the stems off, or you can cut them off with a pair of scissors. If you use scissors, make sure they are long enough to reach all the way through the root system, and that they don’t cut into the roots of other plants in your garden.
When should you not pick rhubarb?
Pick your rhubarb no later than july 4. The harvesting period lasts between 8 and 10 weeks. During the fall and winter, Rhubarb plants are not active. If you try to harvest too late, the stalks will get cold and you will have to wait until the next growing season.
How do you tell if rhubarb is ripe?
The color of the stalks doesn’t indicate readiness, so don’t worry if your stalks are not completely red. Look at the length instead. The stalks are ready to harvest when they’re between 7 and 10 inches long.
Should you let rhubarb flower?
Most gardeners choose to remove the flowers as soon as they appear so the plant can focus its energy on leaf growth. As soon as you see the flowers, you can cut them from the plant. The stems will not be affected if your Rhubarb produces a flower.
If you want to keep the leaves, you will need to cut them off and replant them in a different location. This can be done at any time during the growing season.
Why is my rhubarb not turning red?
Rhubarb’s own debris alters the stem color and you need to do a little maintenance. Rhubarb is high in acid content, like lemons and limes, which tells you that it is sour. The plant prefers soil with a high acidity. So, if you want to keep your plant healthy, you’ll have to add some acid to the soil.
You can do this by adding a small amount of calcium carbonate (available at most garden centers) to your soil, or you can add a few drops of lemon juice or lime juice to a cup of water, and let it sit for a couple of minutes. The acid will neutralize the pH of the water and make it more alkaline.
If you don’t have a pH meter, it’s best to use a soil test kit to make sure that your pH is within the range of 7.2-7.5.
Can rhubarb be harvested all summer?
The stalks are not poisonous and will likely be a little tougher than those in the spring. Rhubarb should not be harvest in the summer months because of plant vigor. The best time to harvest is in late summer or early fall.
This is when the leaves begin to turn yellow and the rhizomes are ready for harvest. If you are harvesting in early spring or late fall, you will have to wait until the next growing season.
How much rhubarb should you harvest?
If your plant has less than 10 petioles but they are all ripe, you should only harvest two to four. If you have several plants from which to take one or two stalks apiece, you can leave the rest to grow for a while longer before you collect again later in the season. Once you’ve harvested your first stalk, you’ll have to wait a few days for the next one to ripen.
If you wait too long, the plant will start to wilt, and you won’t be able to harvest it again until it’s ready to be harvested again. You can also wait until the stalk is fully ripe before harvesting it, but this will take a lot of time and energy, so you might as well harvest as soon as you can.
