<\/p>\n

When you\u2019re planning your garden, you have to know how much space to give to each plant.<\/p>\n

Sure, the seed packets usually recommend how far apart to grow, but how deep will the roots reach?<\/p>\n

Is my raised bed deep enough? What about the leaves? Will they grow so tall that they shade the neighbors?<\/p>\n

Beets (Beta vulgaris<\/em>) are typically considered a fairly small crop, but as with many things in life, there are exceptions.<\/p>\n

Big, giant, huge exceptions. They can actually grow quite large. Or super small. Totally confused?<\/p>\n

Most table beets are similar in size, but sugar beets and mangelwurzel can be massive.<\/p>\n

And there are some table beets that can be downright petite. And then there are the leaves aboveground.<\/p>\n

So, if you\u2019re interested in learning about beet sizes in all their varying glory, stick around. We\u2019re going to cover the following:<\/p>\n

Beet Root Sizes<\/h2>\n

So, how big can beets be? I know it\u2019s the most frustrating answer, but \u201cit depends.\u201d Let\u2019s look at the details:<\/p>\n

For most home gardeners growing standard varieties, you can expect roots to reach one to three inches in diameter and two to three inches long for round varieties.<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

The leafy tops typically grow 12 to 18 inches tall with a spread of six to eight inches wide. But as you\u2019ll see, there\u2019s quite a range depending on variety and growing conditions.<\/p>\n

Sugar beets<\/a><\/strong> and mangel are, by far, the largest of the beet family.<\/p>\n

The Guinness Book of World Records states that the heaviest sugar beet weighed in at 52 pounds 14 ounces, though growers have reportedly grown larger ones without having been certified by Guinness.<\/p>\n

Some accounts claim the largest ever at 156 pounds! That\u2019s larger than many adult humans!<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

The longest variety, including the spindly taproot and not just the main part, was reportedly recorded at 322 inches. That\u2019s longer than four mattresses laid end to end.<\/p>\n

Mangelwurzel regularly grows up to 40 pounds and six feet long. I\u2019ve had them grow nearly that large myself, so it\u2019s not an unusual occurrence.<\/p>\n

The bottom line is that beets are capable of growing exceptionally large.<\/p>\n

But let\u2019s talk about the average size in the garden, particularly for gardeners growing table beets. While these can grow pretty large as well, most of them are more of a medium size.<\/p>\n

The long-time favorite \u2018Detroit Dark Red\u2019 grows to about three inches in diameter.<\/p>\n

By the way, if you want to grow this particular cultivar, the roots are super dark red and deeply flavorful. I always end up coming back to it.<\/p>\n

\n
\"A\"A<\/a><\/figure>\n<\/div>\n

\u2018Detroit Dark Red\u2019<\/a><\/strong><\/p>\n

Grab a pack of about 100 seeds at Botanical Interests<\/a><\/strong>.<\/p>\n

\u2018Early Wonder,\u2019 which matures quickly, is more like two-and-a-half inches in diameter, while \u2018Bull\u2019s Blood\u2019 can top three inches in diameter.\u00a0<\/p>\n

\u2018Baby Ball\u2019 is a delightful inch in diameter at maturity.<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

Of course, plants that are given extra space, rich soil, and ample water might grow larger than the standard.<\/p>\n

The general answer is that most common table varieties are somewhere within the one- to three-inch diameter range.<\/p>\n

When we consider length, things become less consistent.<\/p>\n

\u2018Early Wonder\u2019 are about two to three inches long, as are many round cultivars. But then we move onto the more cylindrical-shaped options.<\/p>\n

The appropriately named \u2018Cylindra\u2019 are a mere one to two inches in diameter, but up to eight inches long.<\/p>\n

\n
\"A\"A<\/a><\/figure>\n<\/div>\n

\u2018Cylindra\u2019<\/a><\/strong><\/p>\n

It\u2019s such a nice option if you want to grow lots in a small space and the shape always draws comments from farmer\u2019s market shoppers and diners.<\/p>\n

Leafy Top Height<\/h2>\n

Okay, so that covers the root, but what about the leafy tops? How big these grow also depends on the cultivar.<\/p>\n

Generally, you can assume the larger the root, the larger the leaves will be, but that\u2019s not always the case.<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

Let\u2019s go back to chunky \u2018Bull\u2019s Blood.\u2019 The leaves on the mature plant can grow up to 18 inches tall. At the same time, petite \u2018Early Wonder\u2019 has greens about the same size.<\/p>\n

With the exception of larger sugar and mangelwurzel greens, which can grow up to two feet tall, expect most greens to be about 16 to 18 inches tall at maturity.<\/p>\n

You can influence this a bit by fostering green growth at the expense of root growth through careful fertilizer applications and pruning.<\/p>\n

Some gardeners grow B. vulgaris<\/em> primarily for the nutritious greens<\/a><\/strong> rather than the roots. Varieties like \u2018Bull\u2019s Blood\u2019 are particularly suited to this purpose.<\/p>\n

Space Requirements for Planning<\/h2>\n

Now that you know how big beets can get, let\u2019s talk about how much room they actually need to reach those sizes.<\/p>\n

Most table beets need eight to 12 inches of loose, friable soil depth for proper development.<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

If you\u2019re growing in raised beds, aim for at least 10 inches of depth to give them adequate room to expand underground.<\/p>\n

Cylindrical varieties like \u2018Cylindra\u2019 appreciate the extra depth even more.<\/p>\n

Your planting density is one of the easiest ways to control final size. If you want to harvest baby beets<\/a><\/strong> for pickling, plant them two inches apart.<\/p>\n

For medium-sized roots perfect for roasting, stick with three to four inches. And if you\u2019re going for those impressive, large roots, give them a full five to six inches of space in all directions.<\/p>\n

The mature foliage spreads six to eight inches wide, so keep this canopy spread in mind when planning rows.<\/p>\n

As a practical example, a standard four-by-four raised bed can comfortably hold 16 to 25 beet plants depending on whether you\u2019re growing compact varieties or larger ones.<\/p>\n

If you are growing beets in containers<\/a><\/strong>, choose pots at least 10 to 12 inches deep and eight to 10 inches in diameter for individual plants.<\/p>\n

How to Influence Growth<\/h2>\n

To encourage root growth, give the plant what these vegetables need to be happy, like full sun, consistent water, and a bit of food. You can learn more about how to grow beets here<\/a><\/strong>.<\/p>\n

As mentioned above, give them adequate spacing for the size you want.<\/p>\n

Make sure the soil is super loose and rock-free. I grow my beets in raised beds to maximize the size, since I have heavy clay soil.<\/p>\n

But if you haven\u2019t been cursed by the soil fairies with heavy clay like I have, you can loosen up your soil adequately using lots of well-rotted compost<\/a><\/strong>.<\/p>\n

\n
\"A\"A<\/figure>\n<\/div>\n

Actually, even if you do have heavy clay, you can loosen it up with well-rotted compost, but plan to do so every year to maintain the looseness, since once the fairies curse you, the curse never lifts.<\/p>\n

If you really want to encourage growth and go for super big ones, you\u2019ve got to discourage the plant from focusing on the tops.<\/p>\n

To do this, prune back the tops a bit to thin them out. You want to remove about a third to a half of the tops by cutting them down at the base.<\/p>\n

Then, feed with bone meal<\/a><\/strong>. This encourages root growth rather than leaf growth.<\/p>\n

Down to Earth Bone Meal<\/a><\/strong><\/p>\n

Snag some bone meal from Down to Earth in five-pound boxes at Arbico Organics<\/a><\/strong>.<\/p>\n

Or, if you want to go the other direction and encourage leaf growth, feed with a nitrogen-heavy food.<\/p>\n

Feather or blood meal is a good option, but I like bat guano because it also includes a bit of phosphorus and potassium.<\/p>\n

\n
\"A\"A<\/a><\/figure>\n<\/div>\n

Down to Earth Bat Guano<\/a><\/strong><\/p>\n

Arbico Organics carries<\/a><\/strong> Down to Earth bat guano in four ounce, two pound or 10 pound compostable containers.<\/p>\n

Either way, feed right around the time you first plant and then again a month later.<\/p>\n
