If you try to harvest your rhubarb too late, the stalks might get frost damage and be inedible. A ripe stalk should be about the width of your finger. Leave thinner stalks on the plant to continue growing.
Make sure the stalks are at least 8 inches 20 cm long. The longer the stalk, the more flavorful it will be. And while 8 inches 20 cm is the minimum length before harvesting, stalks that are between 12 and 18 inches 30 and 46 cm long are the most delicious.
Run your hand along the length of the stalk. If it's crisp and firm, it's ready to pick. Avoid judging a rhubarb plant's ripeness by its color. Contrary to popular belief, how red or vibrant the stalks are does not determine how ripe the plant is. Not all rhubarb is a deep red hue. Some varieties of rhubarb are paler shades of red or even green when they're ready to be picked. Part 2. Twist and pull the stalks as close as possible to the base of the plant. Rhubarb stalks should always be twisted clean from the crown, as twisting or pulling invigorates the roots to produce more.
Pull gently, while twisting the stalk to ensure it comes away neatly. Make sure not to cut or damage the central bulb of the plant which can stunt its growth.
Collect only a third of the stalks per plant each season. This avoids over-stressing the rhubarb plant. Always keep at least 2 stalks on a plant to encourage it to produce again in the next season.
Pull or cut the leaves from the stalk and discard them. The leaves contain oxalic acid, which is poisonous and should not be eaten.
Remove the leaves with your fingers or use a knife or kitchen scissors to carefully cut them off the stalk. Then throw them away or add them to the compost. Make a rhubarb spray from the leaves to keep the pests off plants in your garden like broccoli, cabbage and Brussels sprouts. Do not feed the leaves to animals either! Tidy the plant by removing broken or flowering stalks from the base.
Never leave any broken stalks on the rhubarb plant as these can cause infections to grow. Either eat the pieces or discard them. Remove any flowering stalks, too. This allows the plant to focus on growing healthier stalks instead of flowers. Part 3. Wrap the rhubarb stalks loosely in aluminum foil.
Lay the rhubarb along a sheet of aluminum foil and fold the edges over the stalks. Leave a small space for air to get in and out.
Place the wrapped rhubarb in the fridge for 2 to 4 weeks. The best spot in the fridge for your rhubarb is the vegetable crisper drawer because it has the highest humidity.
After 1 month or if you notice moldy spots, toss any uneaten rhubarb. To freeze the rhubarb properly, first rinse it and pat it dry with a paper towel. Then chop the rhubarb into small pieces and put them in an airtight container or resealable freezer bag.
Place the container in the freezer to use within 1 year. As to why this is happening. There are a few reasons why yours might be going to seed bolting so early on. Mature rhubarb goes to seed more quickly than young rhubarb. Some varieties bolt more quickly than others eg. Victoria and Red Crimson.
Too much heat, rhubarb grows best in cool temp. Stress on the plant that triggers it to put all its energy into seed production sort of like a survival instinct. Stress on rhubarb plants may be caused by too much or not enough nutrients or water, pests or over-harvesting. What to do depends on the reason why your rhubarb is bolting. Consider a newer, slow bolting variety. A good layer of compost or mulch in the fall is always a good bet.
The best rhuberb is grown up in iran contry and special in Neyshabour city. Harvesting Season is April. I planted rhubarb for the first time and it grew without incident. I picked some though and it has no tart flavor. Loamy soils are better for rhubarb growth than sandy soils.
They are more water-retentive and can provide more nutrients to the plant. Soil pH is not important. Any garden soil in Minnesota, whether acidic, neutral or basic "alkaline" , can support a good crop of rhubarb. Garden soil tests, because they are usually from parts of the garden with annual plantings, will not provide information about the rhubarb plant's needs. The rhubarb plant is a "heavy feeder. Make it an annual practice to supplement the soil with either a balanced commercial fertilizer or rich compost, or both.
Addition of manure or compost can add micronutrients and organic matter to soil. Note whether growth is vigorous or weak, and adjust the next spring's fertilizer application accordingly. Continuous use of high phosphorus fertilizer such as or , or high rates of manure or manure compost results in phosphorus buildup in the soil. Some runoff may occur with phosphate fertilizer. It can then become a major pollution concern in our lakes, rivers and streams.
High levels of phosphorus support over-production of algae, which causes significant reduction in water quality. If your soil tests high in phosphorus, use a low phosphorus such as , , or or no phosphorus such as or fertilizer. Selecting plants. Buying rhubarb plants Gardeners often acquire rhubarb plants from another gardener who is dividing a large plant. Choosing rhubarb varieties Different varieties have varying levels of sourness and fibrousness.
Varieties also vary in color from almost pure green to almost pure red. Usually the skin is more or less red, while the flesh color varies from pale to darker green. Color does not cause any specific flavors. Redder varieties are desirable for pies, because the color of the filling is more attractive than the grayish color of cooked green varieties.
Plant stature and vigor also vary among varieties. In general, greener varieties are more vigorous and have longer stalks than red varieties. Rhubarb leaves are toxic. Do not eat them. Only the long, thick leaf petioles, the "stalks," are edible. The stalks contain high levels of oxalic acid, which can tie up calcium and make it unavailable in the body. Eating an occasional dish containing rhubarb does not pose a serious nutritional threat.
People with gout, kidney disorders and rheumatoid arthritis may want to avoid foods high in oxalic acid and should consult with their physicians about consuming these foods.
How to keep your rhubarb plants healthy and productive. Planting Rhubarb plants are very large. That the humble stalks become the dazzling star of so many sweet dishes? Call me strange, but I feel a bond with these little plants. Think of planting from seed like planting from a crown but with an extra year or so tacked on. After another month or two, new petioles should have grown to replace the ones you harvested.
For the rest of the summer, allow the plant to grow untouched. This will help it store up nutrients for winter sustenance, ensuring that you get a healthy crop the following spring.
In Zones 7 and 8, winters are milder. Pick from March through May in these Zones, leaving the plants alone in their hopefully semi-shaded area to weather out the rest of the summer and store energy for the winter.
In this case, you can pick them from about February to April. But in April, go ahead and harvest every single stalk. After April, your plants will probably perish in the summer heat.
Same thing goes for those who plant divisions or bare roots, although this can be problematic in warm climates as root rot easily takes hold of the plants if the soil becomes too hot. I have visions of heading out to my cool, early-summer garden in the morning and plucking stalks for my breakfast crumble. Or weaving my hand through the plant to find the juiciest petioles in the evening for a spur-of-the-moment pie.
All you need to remember is that they should be at least 12 inches long. It helps if you have several plants from which to take one or two stalks apiece, leaving the rest to grow for a while longer before you collect again later in the season.
