9 Reasons Buckwheat Belongs in Your Garden

There are many good reasons to plant buckwheat in your garden. Here are nine of 'em.

When a farmer I know mentioned a couple of years ago that he uses buckwheat alongside his crops, I was intrigued; I peppered him with lots of questions. I’d never heard of this tactic, one he claimed would help deter pests. So of course, I had to try it. It’s been awhile since I’ve tried something completely new and had it work so well.

Buckwheat deters pests

Scattered alongside newly sprouted vegetable seeds or starts, buckwheat seed quickly takes root, reaching its 12-15″ height in just a couple of weeks. Flying pests find it difficult to maneuver through the lush growth of buckwheat to reach their intended target. What this has meant in my garden is that cabbage moths can’t lay eggs on my kale plants (image below), giving them a chance to really get established before they outgrow the buckwheat. I’m hoping that similar holds true as my summer squash starts to bloom. If I can prevent the night-flying moths that produce pickleworms from reaching the flowers, I might just have a shot at growing cucumbers and melons, too.

Surrounding kale with buckwheat helps to deter pests.

Buckwheat attracts beneficials

Honeybees have become a rare enough site that spotting one calls for excitement. Since my buckwheat started blooming, honeybees appear in multiples alongside hover flies and other pollinators. And while they’re here enjoying the plentiful buckwheat flowers, you know they’re helping to pollinate my veggies, too.

Buckwheat makes great animal fodder

If it looks like some of my plants are too shaded by the buckwheat, I clip some to allow a bit more sunlight in. Those clippings go straight to the chickens — they love the greens!

Buckwheat is edible

In and of itself, it can be a crop for gardeners who have the patience to process it. Ripe buckwheat seeds easily fall off the plant. Once the chaff is removed, use a grain mill (like this) to turn the seeds into flour.

Buckwheat reseeds itself

If you’re organized about it, you can collect the seeds to control where it pops up next. If you’re a little more casual about things, like I am, you can let Mother Nature do her thing and just let the seeds fall. To get started, you can buy basic cover crop seed or—if you’re planning to harvest a crop—choose an heirloom variety for better taste.

Buckwheat is a great green manure crop

If you want to juice up your soil a bit, scatter buckwheat seeds on a fallow garden bed or planting area. When it’s about a foot high, use the “chop and drop” method or till it in. Buckwheat is also great at extracting phosphorus from insoluble sources, helping to improve the soil.

Buckwheat keeps weeds at bay

It grows so quickly that the plants shade out many weeds before they have a chance to take hold.

Buckwheat seeds are handy little buggers

You can dry the seeds you harvest and use them as filling for a traditional Japanese pillow, an aromatherapy eye pillow, or a homemade heating pad.

Buckwheat is pretty

Even if it didn’t deter pests or help build soil or feed my chickens, I’d plant it. The soft green is a beautiful way to fill in bare areas.

  • Buckwheat is on my short list of plants I want to establish to attract beneficial insects. It is supposed to be great for attracting hover flies and tachinid flies. Both are great for controlling insect pests. Thanks for the blog post.

    • Kris Bordessa ,

      I’ve been SO impressed with how it attracts beneficials!

  • I love to garden, so it is great to see what new plants I can add. Great post, thanks for sharing!

  • Tim Brenner ,

    Buckwheat ended up in my garden between Cucumbers and squash totally by accident this year – I went looking for Barley seed to grow some out for seed/feed for the chickens for this winter and the Co-op suggested the Buckwheat instead as they didn’t have Barley Seed. So I tried it and boy have I noticed a huge difference in the Squash & Cucumbers this year. I am planning on adding more of it elsewhere in the garden next year. Also excited to try and mill it and see how I can use it. Never had Buckwheat Flour before so it’s an all around new experience for me that I am loving so far. The plant looks nothing like I expected a wheat type plant to look like but gosh it is AMAZING!!

    • Kris Bordessa ,

      Oh, I’m glad to hear it’s working so well for you. I’m LOVING it!

    • Nancy ,

      Buckwheat is not a wheat plant, it is related to Rhubarb.

      • Kris Bordessa ,

        Yes, and buckwheat flour is actually okay for those who are allergic to wheat.

      • Penny ,

        So how do I protect the rhubarb? Are the holes from insects or slugs?

        • Kris Bordessa ,

          Hard to say. Maybe go out at night with a flashlight and see if you can identify the pest? I’m a fan of diatomaceous earth (food grade, not the kind you use for pools) for creepy crawlies.

  • Buddy Maggard ,

    Wow! I will have to try,I’ve heard of Buckwheat pancakes,and flour.This is new,sounds great thanks   

  • Dee ,

    Thanks so much, I didn’t know it was so easy to grow!  I love the bwheat flour and cereals in addition to using the shells for pillows. :)

    • Kris Bordessa ,

      It is TRULY super easy to grow!

  • Irina ,

    Hi,
    Nice ideea, but when should I sow it, if I use toghether with my veggie?
    Thank you very much for your info.
    Irina

    • Kris Bordessa ,

      I scattered seeds when my veggie seedlings were about an inch high.

  • Liana ,

    Oh my. I hope this is the answer I’ve been looking for (sighs at bare kale babies). 

    • Kris Bordessa ,

      I’m not growing *much yet at my new place, but the kale is doing well and not chewed to bits!

    We have 2 buckwheat patches we established in our community garden this year. One was planted early and in part shade, it’s already gone to seed and flopped over. We’ll chop it this weekend and till it in to loosen and amend the soil. The other patch is a bit younger, in full sun and off the CHART! It’s close to 5 feet tall, densely packed with flowers and COVERED with bees… the first time we’ve seen honeybees and native bees in *abundance* in our garden this year. I’ll leave it be(e) until the flowers are gone and chop that up too. I don’t have too many problems with reseeding, as we get our garden fall plowed and folks get in early if they can to work the soil and plant. But it’s easy to pull if you don’t want the seedlings. We love it as a cover crop and a beneficial insect magnet.

    • Kris Bordessa ,

      Good to hear it’s working for you, too!

  • Raia ,

    Great to know! Definitely going to be trying this!

  • Great post about the benefits of Buckwheat!
    One of the nice features about using Buckwheat as a cover crop is that the plants are quite tender and have hollow stems. They decompose rapidly, so it’s possible to plant another crop without a long wait.

  • Hilda ,

    Thanks for this information. I have only planted buckwheat as a winter crop, to improve the soil, but will start to make it a regular in my garden. 

  • I have been growing buckwheat for five years.  It is the gift that keeps on giving.  It self seeds itself in lots of places.  In the north, it is best to seed it in June for a fall harvest.  It is a cool weather plant.

    The bees adore it.  Unfortunately, I haven’t seen the benefits of reduce bug population.  This year the patch was pretty close to my pumpkin, zucchini and squash but that dreaded squash bug and borer are very happy reeking havoc on my plants. :)

    • Kris Bordessa ,

      I still have squash bugs. 😉 The buckwheat seems to deter the flying pests like cabbage moths more than anything. I’ll take what I can get!

    • I find Amaranth in companion planting pulls cucumber beetles away from my cucumbers and squash. Apparently it tastes better.

  • I also have buckwheat in my garden. I love it! I planted it at home in town for seed harvesting and on our land in the country as green manure to better the soil since we have red clay and we are planning to start a vegetables farm next spring. In town, we didn’t get too many bees, but on our land in the country the field is full of buzzing bees. They say that bees produce dark (almost black) honey when drinking from the buckwheat. I would love to taste that.  

    • Kris Bordessa ,

      Maybe I should invite a beekeeper to come set up hives!?

  • Hope ,

    Where I can I find buckwheat seeds, I don’t remember seeing them in the seed section at the store.

  • Sean ,

    I’ve been planting buckwheat for a few years now, and thought I’d add a few things:
    1) It grows very well in ALL kinds of soil, making it a great choice to plant in areas where other plants don’t grow so well.
    2) It’s a “quick crop,” taking only 4-6 weeks from planting to flowering.
    3) it’s a great crop for food plots to attract deer.  They love to eat their way along the tender greens, but the buckwheat weathers this foraging very well.
    4) This was noted above, but to reinforce, there is no better plant for pollinators.  I can tell when my buckwheat blooms by watching the entrance to my beehives, and the honey that comes from buckwheat is some of my favorite.
    5) It’s inexpensive.  I get mine from the local farm bureau or elevator, and I get a 50 lb bag for $1/lb.  This gives me about 1 acre of buckwheat, maybe a little less.

    • Carol ,

      And exactly WHY would having deer love being in your garden a GOOD thing? I’ve not discouraged deer so far on my place, but I really haven’t had much of a garden to protect. This year, I had some volunteer tomatoes crop up, and yesterday, they were GONE! Eaten by those same deer you seem to think are a good thing in a garden! Anyway, thanks for the heads up on that particular point, now I don’t know if I want to plant it or not……;-(

      • Kris Bordessa ,

        I’m with you – I want the deer outside of the garden. When I read that I assumed Sean meant that the buckwheat – planted elsewhere – might attract deer away from the veggies.

        • Sonuahua ,

          I’m not sure if it is what Sean meant but if you had acreage set aside for hunting purposes, it would provide inexpensive, self-propigating fodder for grazing your future food source. Deer are also fond of red clover.

  • Paigan ,

    I planted buckwheat last year and let it re-seed naturally this year. It is a pretty plant I love it in the spring and throughout the summer. It sprang up around, my first ever attempt to grow potatoes this year. I have had absolutely no pests problems in my six baskets of spuds, not one chewed leaf or weird fungi or anything. It is lovely and helpful.

    • Kris Bordessa ,

      That is so cool!

  • Heather Vande Walle ,

    Buckwheat not only makes a good cover crop for soil amendment, but we planted it, along with yellow sweet clover, for our bees. The combination made a mellow dark honey that was just fantastic.

  • Rae Ellis ,

    I’m searching for land to purchase this next year and buckwheat will be one of the first things planted. I plan on planting an acre of it and having several beehives in that field. for buckwheat honey, a high demand honey that sells for about $13.00/pound currently.
    Almost every part of the plant can be used if you want to process it.
    One warning…buckwheat can be toxic to some animals: dogs, cats, horses and alpaca to name a few so use caution with where you plant it being mindful of animal visits.

    • Kris Bordessa ,

      Thanks for that warning!

  • Jessica ,

    How can I incorporate this into a square foot raised garden? If I can only technically plant, say, 2 kale plants per 12 inch square, can I still plant the buckwheat around it without harming the kale plants by taking up their space or nutrients? Thanks!

    • Kris Bordessa ,

      Good question! Maybe you can’t? (I’m not a square foot garden expert at all.) Maybe someone will chime in. For sure, plant it *around the garden for the bees.

  • Kari ,

    I’m new to gardening this season and I already have veggie seedlings started indoors. I’m going to move them outside once it is warmer, but how should I add the buckwheat ? What I mean is, should it be planted in rows? Around? I don’t have a very big plot for gardening, it’s about 5ft x 8ft.

    • Kris Bordessa ,

      Let your seedlings get a head start; buckwheat grows fast and will outpace them quickly. Once they’re established, just cast handfuls of buckwheat over the garden bed.

  • Claudia Phillips ,

    Thanks for the great information. I will definately be planting buckwheat.

  • Richard James ,

    Buckwheat honey is also considered a delicacy and can be used it gingerbread making in replace of molasses. Buckwheat pancakes are nice too! Thx for sharing this great article.
