Lack of Vigor
Poor soil and drought conditions can reduce a rhubarb plant’s overall health. Seeing thin rhubarb stalks on a mature, established plant that is not overcrowded can be a sign of declining growing conditions. The solution: In arid climates and during periods of drought, water rhubarb weekly..

Why does my rhubarb only produce thin stems?
The most common reason for rhubarb having thin, spindly stalks is that the plant itself has gotten too large and mature. It seems counter-intuitive, but for rhubarb, a massive plant is the same problem as overcrowding with other plants (which is another cause of thin stalks).
Does picking rhubarb encourage growth?
There’s no need to use a knife when harvesting rhubarb, simply pull and twist the stems off the plant, as this stimulates fresh new growth. Forced rhubarb is usually ready from late winter to early spring.
Does rhubarb need lots of water?
Water and Moisture Requirements
If your rhubarb is getting too dry, water is well, about an inch every week. Watering needs to be “deep watering” to allow the roots to benefit. Rhubarb should not be overwatered because it is susceptible to crown rot.
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 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.

Most vegetables like soil on the slightly alkaline side, but acid-loving vegetables like radishes, parsley, potatoes, peppers and rhubarb can get a boost from fresh coffee grounds.
What should not be planted near rhubarb?
Meanwhile, melon, black walnut, cucumber, pumpkin, and dock do not go well with rhubarb in a garden or food forest.
Should you put manure on rhubarb? Autumn: When the leaves die back naturally, simply cut back the old rhubarb stalks to leave the buds exposed. Apply a mulch of well-rotted manure around the crown of the plant; this will help to conserve moisture in the soil and keep the weeds down, as well as feeding the plants for the following growing season.
How do you rejuvenate rhubarb?
The more they dry out, the worse the prognosis for the new plants. If this isn’t possible, put the pieces in a plastic bag and store in the refrigerator for a short time. Before replanting the refrigerated rhubarb, soak the root divisions in room temperature water for several hours or overnight.
What is the best fertilizer for rhubarb?
Rhubarb plants respond best when they are fertilized with 10-10-10 fertilizer or a combination of composted manure and phosphorus. While 10-10-10 fertilizer is a great choice, if you want to follow an all-natural gardening plan, the compost-and-phosphorus method is the organic choice for rhubarb.
When Should rhubarb be cut back?
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.
What’s the best fertilizer for rhubarb?
Should I mulch around rhubarb?
Spread a layer of organic mulch, such as dried leaves or straw, around the rhubarb plant. The mulch keeps the weeds down and helps the soil retain moisture. You can use thick cardboard or several layers of newspaper if other mulch is not available.
Should I put manure on my rhubarb? Rhubarb needs a soil that is both fertile and free-draining, as the crowns will rot if left to sit in cold, wet soil. To improve the soil’s structure and fertility, dig in lots of compost or well-rotted farmyard manure a few weeks before planting.
Does rhubarb like wet soil? Grow rhubarb in full sun, in rich, lightly moist soil. In hot regions (USDA hardiness zone 6 and higher), plant rhubarb where it will get some protection from hot afternoon sun. Rhubarb will not thrive in a soggy location, where it will be susceptible to root rot, one of the few problems rhubarb can encounter.
Should I cut off dead rhubarb leaves? 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.
Why is my rhubarb not growing properly?
Overcrowding is common problem with rhubarb and can lead to subpar growth. Dig and split rhubarb roots every 3 to 4 years. Divide when plants are dormant in early spring (or late fall). Divisions should have at least one large bud on them.
Should you water rhubarb?
Rhubarb needs consistent watering. It’s a good idea to keep the soil moist around the plant. When watering rhubarb, keep these points in mind: Water your plants at their base; otherwise, wet foliage may encourage pest and disease problems to develop.
Can rhubarb get too much water?
It’s definitely possible to overwater rhubarb. The plants do not like soggy soil. Well-draining soil will recover quickly if you accidentally add too much water. Just skip watering the plants for a few extra days to let the soil dry out.
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.
Is Miracle Grow good for rhubarb?
Miracle-Gro, on the other hand, is high in nitrogen and potassium but contains relatively little phosphorus. While this is good for some flowers, it is not ideal for a perennial vegetable such as rhubarb.
Should you water rhubarb everyday?

Can you overwater rhubarb?
While mature plants can be somewhat tolerant to drought, rhubarb in its first two years of growing needs regular watering. However, don’t overwater rhubarb, as the crowns can rot in wet soil. A good rule is to water the plant when the top inch of soil dries out.
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.
