How Many Plants Can You Fit Per Acre?

It is easy to forget how big an acre of land is. In planning for planting I often find it useful to think about how many plants I can fit in an acre of land with a given spacing.

Here is an example of how we'd use this chart on the farm. We plan on using half of our land to support the other half by growing compost crops on it. If we were to use comfrey as the only plant for the support section we would need 3 acres of comfrey. If we planted it with 3 x 3 foot spacing we would need to have 14520 comfrey plants on the property. (That's a lot of comfrey!)

If we were planting large trees that needed significant spacing like pecans we might use the 40 x 40 foot spacing which would give us only 27 trees per acre. We won't be, but if we did, we could plant something small like carrots with the 3 in x 3 in spacing and have almost 700,000 carrots per acre!

Does Comfrey Need TLC?

Comfrey is an incredibly robust plant but giving it some love just makes it produce even more. Here are comfrey plants that were all planted at the same time (6 months ago) and are only a few feet away from each other. They were all started from Bocking 14 root cuttings.

This root was planted in poor soil (hard, crusty clay) and not given any attention. After 6 months all it has produced is 2 little leaves. If I had given it any attention - extra moisture/nitrogen/mulching it probably would be thriving just like my other plants.
Just a few feet away is another plant that is in better soil but still didn't receive any extra attention. Several leaves and growing well but nothing amazing.
And finally these plants were planted in a low lying area that receives significant moisture and nutrient run off. They are only 6 months old but easily look like plants that are a couple of years old.
So to answer the question - does comfrey need TLC? Yes and no. If you just want some comfrey to grow and don't need leaves immediately, then putting it anywhere will do. However, if you want to see all that comfrey can do then you'll need to put it somewhere nice. A perfect place can be downhill from a compost pile. It will receive nutrients that runoff the pile and will put on significant growth in no time.

Comfrey as Mulch

Using comfrey as a mulch in your garden/farm is a great idea depending on your needs.  If you are looking for a mulch that can start feeding your crops really quickly, this is your answer. The leaves of the plant are low in fiber so it breaks down quickly after mulching with it. Depending on several factors, it can easily decompose within days providing nutrients to the soil underneath it.

For mulching with comfrey there are 3 options all of which have big benefits.

Move to location – This simply involves cutting the leaves off a comfrey plant (or harvesting the entire plant) and using them as mulch elsewhere. This is what we do for our raised beds on the farm. We have a comfrey patch that is near the beds, and when needed, we cut off leaves and bring them up to the bed. A small patch can be used to mulch a rather large raised bed.

 This is one of our <1-year-old comfrey patches used for that purpose - 
Once established this patch can produce a ton (yes, 2000 pounds!) of comfrey leaves a year. 

Chop and Drop – If you've planted your comfrey plants near (within the drip zone) the trees you want to fertilize you can simply cut off the comfrey leaves where they are and leave them. Almost as easy as possible.

Let die in winter – As easy as possible. Again for comfrey that has been planted near trees you can simply let the comfrey die back each winter fertilizing the ground around the plant. You don't get as much mulch as you would if you cut it back a couple of times during the year, but it requires absolutely no work. Some call it lazy, I call it being efficient. 
 
Here is comfrey as it begins to die back during winter. The dead leaves are very dark in color which makes the soil darker as it enriches it. - 

We Love Comfrey!

Comfrey is our favorite and most important plant on the farm.


We grow more comfrey than any other plant number wise and space wise. We currently have about 1000 plants and hope to eventually have over 5000.
Books have been written about this amazing herb over the years so I obviously won't be including all of that information here. I do want to highlight some of comfrey's most positive features so that everyone can understand how great of a plant this is.

Sweet Potatoes

Our first harvest of sweet potatoes are coming in.

This is the harvest from just one plant. Those sweet potatoes weighed in at 7 pounds give or take a few ounces. A very brief search online indicated that the average harvest is about 2.5 pounds of sweet potatoes per plant so we are doing very well so far.

My wife makes sweet potato burritos fairly often and then freezes them to have a quick and healthy dinner when needed. Our goal is to grow 200 pounds of sweet potatoes next year and make them one of our staples. We'll see how that goes.

Growing sweet potatoes well is an interesting challenge because they do NOT perform well in soil that has high amount of nitrogen which is the opposite of most other plants we grow on the farm.

Pecans are sold out!



Our pecans are hand-picked, hand-shelled, naturally fertilized and go straight from our farm to your door.

Thanks to everyone who purchased our pecans as we are all sold out for this year!  Pecans will be back next year starting around Oct/Nov.

 

Information on the pecan:

     Pecans are undoubtedly the most important nut trees native to North America. Although named for their northern most habitat, pecans are actually indigenous to a wide geographical areas, including Texas, Oklahoma, Louisiana, Mississippi, Arkansas, Missouri, Kansas, Kentucky, Tennessee, Illinois, Indiana, Nebraska, Iowa and Mexico as far south as Oaxaca. For North American Indian tribes in the south central region of the United States, especially in the Mississippi Valley, the pecan served as a dietary staple long before the arrival of Europeans. Later they traded pecans to the settlers for furs, trinkets and tobacco. Before the early sixteenth century, no European had ever seen a pecan nut.
     Texas was blessed with more native pecan trees than any other state: possibly as many as seventy-five million growing wild, mostly near the states many watercourses. The pecan is the official state tree of Texas. The first United States commercial pecan orchard was planted in Brownwood, Texas in 1880. Between 1900 and 1925, numerous real estate projects, which featured pecan trees were developed in the southeastern states. Hundreds of thousands of acres were planted, mostly with Stuart variety pecans in Georgia, Alabama, Mississippi and northern Florida.
     It took about four centuries for the pecan to become an important crop in the United States: it reached commercial scale in 1920 and has increased steadily ever since. The average, annual pecan production is now over 200 million pounds, although there is considerable variation from year to year. The pecan industry, like the macadamia nut has largely developed during the twentieth century. Most edible tree nuts are essentially one state crops: almonds, pistachios, walnuts in California; filberts in Oregon and macadamia nuts in Hawaii. The pecan is a multi-state crop, stretching across the country from the Southeast to the Southwest throughout some twenty states.
     The most important and largest producing states in the country are Georgia and Texas, Alabama, New Mexico, and Louisiana. The pecan, although it resembles the walnut, is more elongated, has a smoother shell and a higher proportion of kernel in its shell. In the pecan, the partitions which separate the two halves of the kernel are thinner than in the walnut. When mature, the husk of the pecan, unlike that of the walnut, splits open into four segments.
     The pecan is a large, stately deciduous tree. Under favorable circumstances it may grow to over one hundred feet in height, with a trunk diameter of six feet and a limb spread of some 100 feet. Pecan trees are very long lived; some native trees in the Southeast are known to be over a thousand years old. Once fallen to the ground, the pecans are harvested, cleaned, and either packed in shell or shelled and graded. The largest demand for shelled pecans is in the baking industry. The versatile pecan continues to grow in popularity every year.

I just have to know. Is it PEE-CAN or PA-KAWN?
A 2003 national survey found that "PEE-can" is the overwhelming choice among Americans. Nearly half of consumers (45 percent, including almost seven out of 10 living in the Northeast) prefer this pronunciation of the all-American tree nut, with the rest of the nation roughly split between pa-KAWN and PEE-kawn (Source: National Pecan Shellers Association).

  • Pecan nuts are rich source of energy, provide 690 cal/100 g and contain many health benefiting nutrients, minerals, antioxidants and vitamins that are essential for wellbeing. 
  • These nuts are rich in monounsaturated fatty acids like oleic acid and an excellent source of antioxidants. Regular intake of pecan nuts in the diet help to lower total as well as LDL or “bad cholesterol” and increase HDL or “good cholesterol” levels in the blood. Research studies suggest that Mediterranean diet, which is rich in dietary-fiber, mono-unsaturated fatty acids, and antioxidants would help to prevent coronary artery disease and strokes by favoring healthy blood lipid profile.
  • Pecan nuts are rich source of many phyto-chemical substances that may contribute to their overall antioxidant activity, including polyphenolic antioxidant ellagic acid, vitamin E, beta-carotenes, lutein and zeaxanthin. Research studies have been suggestive of that these compounds help body remove toxic oxygen free radicals and thus, protect body from diseases, cancers, as well as infections.
  • Anti-proliferative properties of ellagic acid are because of its ability to inhibit DNA binding of certain carcinogens such as nitrosamines and polycyclic aromatic hydrocarbons; thus protecting body from cancers.
  • Pecans are an excellent source of vitamin-E, especially rich in gamma-tocopherol; provides about 25g per100 g. Vitamin E is a powerful lipid soluble antioxidant, required for maintaining the integrity of cell membrane of mucus membranes and skin by protecting it from harmful oxygen free radicals.
  • The nuts are packed with many important B-complex groups of vitamins such as riboflavin, niacin, thiamin, pantothenic acid, vitamin B-6, and folates. These vitamins functions as co-factors for enzymes during cellular substrate metabolism.
  • The nuts are also rich source of minerals like manganese, potassium, calcium, iron, magnesium, zinc, and selenium.
