Best Fertilizer for Rhubarb

Many people often wonder what the best fertilizer for rhubarb is. While some people will swear by things like Miracle Grow, others tend to suggest that there is no requirement for fertilizer at all. The truth of the matter is that both approaches are fine, depending on the results you want to get.

While it is true you can grow rhubarb without any treatment, the flavor and the size of the plants will be smaller when you compare them to plants that do receive the fertilizer. In turn, Miracle Grow tends to be one of those catch all products that can help with the size of the plants, but what you will find is that this slow fertilizer does not offer you the best fertilizer for rhubarb by any means.

Instead, what you are going to want to consider is your basic manure. What most people tend to find is that farm manure will help to add the nutrients that rhubarb will end up needing and provide the necessary nutrients to create large plants that do have some excellent flavor. While you might be aware of manure, you need to keep in mind that the nutrients are all that goes down into the soil to create the perfect growing conditions for these plants.

If you are looking for an excellent option to help grow your plants, then you will want to truly look at manure as being the best fertilizer for rhubarb. With years of proven results, you will find that it does stand out beyond the rest of the choices out there.

How to Divide Rhubarb Crowns

Growing your own rhubarb is very rewarding and there will come a time when you want to divide your rhubarb crowns in order to get more plants or to thin out the ones you have. You can propagate rhubarb by planting the pieces you get when you divide four or five year old crowns. You can divide earlier if you want more rhubarb plants.

Divide them in the fall or spring, waiting until you see early growth just beginning so you can see where to divide the crown. Dig the crowns up with the roots and take care not to damage them, then cut them into four to eight pieces. Split dormant crowns between the ‘eyes’ (big buds) and make sure you do not break off the delicate buds. The roots are quite hardy though and will tolerate rough handling.

The smallest buds will give small rhubarb plants for several years after you plant them, but you can get between four and ten new roots from crowns which have been growing for longer. Protect your root pieces from freezing or drying out if you are not planting them right away. When you are dividing the crowns to be replanted, mark the vigorous plants in June then use them as planting stock for the next spring.

Check for Rot and Disease

Do not divide crowns from diseased plants. Before replanting the divisions you should examine the root area for excessive decay and rot, and discard it if there is a lot. There will normally be some rot because that is part of the plant’s normal growth, so if there is just a little you can easily cut it off before replanting.



One Response to Best Fertilizer for Rhubarb

  • I applaud the entire article–well written and practical. I would only hazard people to be wary of manure fertilizers–not that they don’t do all you say and possibly more–but because of the potential for herbicide carry-over that exists now days. We have some chemistries available to folks nowadays that do a tremendous job of keeping broad-leaf weeds out of grass hay and straw crops. UNFORTUNATELY, some chemistries do carryover into the manure through the intake of said fodder. Same thing when using straw mulch. So, the age old very best fertilizer is now rendered ‘suspect’ in the destruction of backyard flower and vegetable gardens. That said, run a simple bio-assay (test the fertilizer or mulch on a sunflower or tomato plant) and if there is no trouble, go for it!
