How Should You Fertilize Rhubarb?
Fertilize your rhubarb plants early in the spring the year after they are planted, before they begin to sprout noticeably. A decent all-purpose fertilizer to use is 10-10-10. As a fertilizer, compost or well-rotted manure can be used. Make sure to follow the manufacturer’s recommendations if you use granular fertilizer. 1 1/2 pounds per 100 square feet is the typical rate of application.
Do not allow any of the granules to come into direct touch with the plant when scattering them in a circle around it. As a result, the plant can be damaged in some way. It is important to water thoroughly after applying the granular fertilizer. If you decide to use a water-soluble fertilizer, you can use a hose-end sprayer, a watering can, or a bucket. You can now begin harvesting your rhubarb plants now that they are flourishing.
Advice:
Regardless of the fertilizer you use, avoid getting it in contact with the stems of this vegetable. Keep a few centimeters away; this will prevent the plant from being burned. Additionally, keep in mind that when it comes to fertilizing more in less time, it is preferable to fall short of the dose than to exceed it.
Finally, when using rhubarb fertilizers, carefully read the directions on the fertilizer package. Each quality fertilizer comes with easy-to-follow directions for use. If you’re combining it with organic fertilizer, you can use lesser quantities than those indicated in the guidelines.
When Should I Fertilize Rhubarb?
In the first year of planting, you should feed new rhubarb plants in March or April to jump-start their growth. This is the best time of year to add organic matter to the soil. Fertilizer will be absorbed into the soil as you water your rhubarb. The rhubarb roots and crowns will benefit from this, and the outcome will be a bumper crop of rhubarb stalks.
Your rhubarb will benefit from an extra dose of fertilizer in the fall, in addition to what you used in the spring. As soon as your rhubarb crowns have ceased generating new stalks, in September or October, you should cut them back. 4 weeks before the first normal autumn frost, apply fertilizer to your plants. This permits the plant to absorb the nutrients from the fertilizer and strengthen itself before the winter. The second year’s crop will be stronger as a result. These Rhubarb plants need to be fertilized three to four times per year.
3 of The Best Fertilizers For Rhubarb
Rhubarb is a perennial vegetable, which means that once it is established, you can harvest the crimson stalks for up to 5 years after they are planted. And it is for this reason that a decent fertilizer is required to ensure that it continues to develop strongly.
However, We recommend using a fertilizer with an NPK ratio of 12-12-12 for your rhubarb plants in garden centers or home gardens. Calcium and magnesium can also be good for your plant’s health in a fertilizer mix. Accordingly, below are some excellent fertilizers that will meet your expectations.

Does Rhubarb Need A Lot Of Fertilizer?
Yes! A perennial plant, Rhubarb can be counted on to live in your garden for many years to come when given its essential nutrients. In the spring and fall or early winter, rhubarb needs fertilizer with good drainage because it is long-lived.
Annual vegetables, on the other hand, often only require fertilization in the springtime. The amount of fertilizer needed for a rhubarb patch is, therefore, two times greater than that required for an annual vegetable patch. In the summer and late summer, you should not need to fertilize Rhubarb.
Additionally, the amount of fertilizer required by your plants will vary according to their size and variety. If you’re using a slow-release pellet, it’s recommended to use approximately two pounds per 100 square feet. We approve one gallon of liquid fertilizer per 200 square foot planting space in early spring when new shoots emerge from the earth.
Conclusion
After it has established itself, you can reap the reddish stalks of rhubarb for up to five years.
To get the finest fertilizer for your Rhubarb, look for vegetable and herb fertilizers, all-purpose fertilizers, or balanced fertilizers. You can also add compost, manure, or green manure to the soil to increase its organic content.
So with this in mind, I’m crossing my fingers that you’ll find the best Rhubarb fertilizer and take good care of your plant. The best of luck to you, my friend!
