Alfalfa can remain productive in stands from four to ten years or more, but as plant population declines renovation eventually becomes necessary.
Does alfalfa take a lot of water?
Alfalfa is a high water use crop because it has a long growing season, a deep root system, and a dense mass of vegetation. … Commonly cited ranges in water requirements for alfalfa are 18 to 36 inches of water per season. Alfalfa is quite tolerant of drought or extended periods without highly available water.
How often does alfalfa need to be replanted?
Alfalfa should never be replanted into the same field for at least one year due to the alleopathic effect of mature plants on development of new seedlings and minimal risk of disease for the new planting.
What happens if you don't cut alfalfa?
If it stays dry those new shoots could die off. Once your alfalfa does receive enough rain for regrowth it might regrow a little faster if it’s cut, but it also will regrow following sufficient rain without cutting. In most cases, it’s not worth the cost and time involved to shred, clip, or harvest low-yielding hay.
Does alfalfa grow back every year?
Alfalfa is a cool-season perennial commonly grown for feeding livestock or as a cover crop and soil conditioner. It’s ideal for improving the soil and providing erosion control. … Alfalfa’s extensive root system nourishes both plants and soil.
Can alfalfa regrow after cutting?
Alfalfa takes about 40 days to develop the ability to regrow from the crown after cutting. Plants cut before this point need at least one set of leaves remaining to regrow. … Winter injury can be severe due to reduced winterhardiness of new plants.
Can alfalfa reseed itself?
Alfalfa is a crop that naturally tends to lessen its density over time because alfalfa doesn’t reseed itself. Planting more alfalfa into current alfalfa fields is not recommended since alfalfa has autotoxicity characteristics. A good population/density is about 35 well-growing stems per square foot.
How often does alfalfa need to be watered?
During late April and early May, water use may be only 0.5 to 1.0 inches per week. By early June, this can increase to 1.5 inches per week, while during the warmest part of the irrigation season, water use might be as high as 2.0 inches per week.
How tall does alfalfa get?
Alfalfa is a perennial forage legume which normally lives four to eight years, but can live more than 20 years, depending on variety and climate. The plant grows to a height of up to 1 metre (3 feet 3 inches), and has a deep root system, sometimes growing to a depth of more than 15 m (49 ft) to reach groundwater.
How many times can you cut alfalfa per year?
Researchers from the upper mid-West suggest more income will be available by harvesting four times per year rather than three times, and that more frequent timely cutting will increase forage quality.

How many times can you cut alfalfa in a year?
Similarly, research conducted in the Central Valley of California by Dan Putnam, University of California forage specialist, compared cutting alfalfa every 24 to 26 days (8 cuts per year), a 28-day schedule (7 cuts per year), and a 32-day cutting interval (6 cuts per year).
What happens if you cut alfalfa too early?
Realize that if you are cutting alfalfa earlier there will be a yield reduction and possibly a reduction in stand longevity. First cutting alfalfa changes rapidly at this time, and weather delays will decrease forage quality.
What do you plant after alfalfa?
Consequently, after harvesting the alfalfa production of the 4th year, most farmers destroy their alfalfa plants by plowing deeply and then they sow wheat, corn or barley in the field.
How long can you store alfalfa seed?

What kills alfalfa?
A highly effective herbicide option for fall termination of alfalfa is 2,4–D amine or ester used alone or tank mixed with dicamba products. If grasses are present with alfalfa, a good option is to tank-mix glyphosate with 2,4–D.
How long does it take alfalfa to bloom?
Harvesting of Alfalfa During the Establishment Year The first harvest can be made before flowers begin to appear, but waiting for the alfalfa to flower will ensure greater energy reserves in the roots. Alfalfa will generally reach this stage of development between 60 and 70 days after emergence.
How much does it cost to grow an acre of alfalfa?
Cropland with district water suitable for alfalfa production typically ranges in value among counties from $15,000 to $25,000 per acre. The land in this study is owned by the grower and cost $15,000 per acre. Small farms (50 acres and less) tend to have higher land costs than farms over 50 acres.
Can you cut alfalfa before it blooms?
Many growers cut soon after the first blooms appear; however, weather can cause long delays and sometimes alfalfa doesn’t bloom very aggressively during spring. … Plus, waiting until alfalfa begins to bloom often results in hay that is too low quality for dairy use.
How long does alfalfa stay green?
This coincides with the date of the first alfalfa killing frosts (<25 F) in many regions. Beyond this date herbage regrowth will be minimal. Even after these first frosts we have observed that leaves near the soil surface often survive and can stay green and conduct photosynthesis into late November.
How do you collect alfalfa seeds?
Enter the growing area when the seed bunches are visible on the tops of the plant stalks. Grasp each stalk gently and pull upwards, allowing the seeds to fall into your hand. Place the seeds into a cloth sack. Store the sacks of alfalfa seeds in a cool, dark and dry place until you are ready to plant or sell them.
How do you know if alfalfa is good?
Good quality hay should be bright green in color with little fading. A bleached, yellow, brown or black color may indicate aged hay, mold or poor storage conditions. Storage condition and age have a significant effect on vitamin content of hays.
How short do you cut alfalfa?
Alfalfa or Clover 2″ minimum. Some literature shows a cutting height of 1″ will not reduce stand longevity, but remember the increased ash content issue. Also, keep in mind that frequent cutting at early maturity will continue to deplete carbohydrate reserves.
Do you have to cut alfalfa?
Most dairy producers are fairly aggressive with alfalfa cutting schedules. Their goal is to achieve high-quality forage. But cutting too frequently usually shortens the life of alfalfa and often gives lower yields, even when more cuttings are taken per growing season.
What are the side effects of alfalfa?
Possible Side Effects. Alfalfa sprouts are considered safe and nutritious but may cause side effects in some people. Due to its high fiber content, consuming raw alfalfa can cause gas, abdominal discomfort, and diarrhea.
Does alfalfa keep growing after it blooms?
The optimal time to do so, Anderson says, is about 10 days after the first blooms appear on alfalfa plants. … “If your alfalfa receives enough moisture to support regrowth through the year, harvesting three cuts at full bloom should give you about 10% more total yield than taking four cuts at first bloom,” Anderson says.
How much does alfalfa grow per day?
Daily evapotranspiration of alfalfa is small, generally between 0.05 and 0.1 inches per day, at the start of the crop growing season, which varies depending on climate characteristics, increases with time of year to maximum values between 0.3 and 0.4 inches per day in June/July, and then decreases to small values at …
Can you flood irrigate alfalfa?
Flood irrigation is commonly used for alfalfa irrigation in the Central Valley of California. This irrigation method uses the soil surface to flow water down the field. Thus, its performance is highly dependent on soil properties such as infiltration rate and surface roughness.
When should you mow alfalfa?
For higher value forage The optimal compromise for higher forage quality and dry matter yield of alfalfa is to harvest the first cutting at the late-bud to first-flower stage and to make subsequent cuttings at 32-to-35 day intervals until late August or early-September, often referred to as a “4 summer-cut system.”
Which cut of alfalfa is best?
Second cut alfalfa hay is usually the fastest growing because it is developing during the hottest part of the season, and it usually has more stem in relation to leaf. Of all cuttings, second cut tends to be the lowest in crude protein, but its 16 percent average is adequate for all classes of horses.
Can you drill alfalfa?
A good alfalfa seedbed is one that makes you want to bring friends to the field and say, “I did that.” If your seedbed is not that good, don’t plant alfalfa. Use a drill to plant. Do not broadcast seed and till it in. If you can’t use a drill, don’t plant alfalfa.
Can you overseed alfalfa into grass?
Grasses typically will typically overtake the alfalfa over time. Thus overseeding alfalfa into existing alfalfa can work in some cases, but is fraught with risk.
