Growing Alfalfa: Annual Vs Perennial And Taproots
When considering the growth of alfalfa, it is important to understand the distinction between annual and perennial varieties.
-
Annual alfalfa is typically cultivated for one season and requires reseeding each year. It is commonly used as a cover crop or green manure to improve soil health and reduce erosion. The shallow taproots of annual alfalfa do not extend as deeply as perennial varieties, making it easier to incorporate into crop rotations.
-
Perennial alfalfa, on the other hand, offers the advantage of multiple harvests throughout the growing season. It is commonly used as a forage crop for livestock, providing a consistent source of nutrition. Perennial alfalfa’s deep taproots enable it to access water and nutrients from lower soil layers, making it more resilient to drought conditions.
Regardless of whether you choose to grow annual or perennial alfalfa, it is essential to provide a dedicated space for its cultivation. Proper management, including weed control and grazing rotation for livestock, is necessary for maintaining the health and productivity of the crop.
Harvesting And Feeding Considerations For Alfalfa
When it comes to harvesting alfalfa, timing is key. The plant is typically harvested by cutting it above the crown, which allows new stalks to grow from the buds. For the best quality hay or mulch, it is recommended to start seeds four to six inches apart and later thin them to six inches apart. This spacing allows for better growth and easier harvesting.
In warmer climates, multiple cuts can be obtained throughout the summer, while colder regions may experience only three cuts per season.
While alfalfa is an excellent food source for livestock such as horses, rabbits, guinea pigs, sheep, and cows, certain precautions must be taken. Alfalfa, when consumed in large quantities, can cause bloat in ruminants. Additionally, the saponin content in alfalfa makes it unsuitable for excessive feeding to swine or poultry.

Planting And Propagation Techniques For Alfalfa
To start growing alfalfa, you have the option of propagating it from seed or using cuttings. If you choose to sow alfalfa from seed, it is crucial to ensure that the seeds are inoculated with rhizobium bacteria. These bacteria play a critical role in fixing nitrogen in the soil, providing an essential nutrient for the growth of alfalfa. If you decide to use non-inoculated seeds, it is necessary to inoculate them yourself before planting.
When choosing a location for planting alfalfa, look for areas that require more organic material or improved aeration. The extensive taproots of alfalfa can penetrate depths of over 10 feet, while the surface roots can spread over 20 feet. Therefore, it is crucial to provide well-draining soil with a pH level of at least 6.0 for optimal growth.
The timing of planting is also crucial. Fall is generally recommended as the ideal time for planting alfalfa to avoid competition with spring weeds. Before sowing the seeds, it is essential to eliminate any existing weeds in the designated area to prevent competition with the seedlings.
When planting the alfalfa seeds, rake the top layer of soil to create an even surface. Plant the seeds half an inch deep, with two seeds spaced two or three inches apart. This spacing allows for sufficient growth and development of the seedlings. Once the sprouts break through the soil, provide regular watering to ensure their healthy growth.
For those who prefer to propagate alfalfa through cuttings, it is essential to start the cuttings early, enabling them to be planted out in the spring or summer. Cuttings should be taken from healthy stalks that have reached a height of at least six inches. Cut the stalks two inches from the soil to encourage new growth, and strip the leaves from the bottom section, leaving the top three leaves intact.
To prepare the cuttings for rooting, place them in a glass of water overnight. The following day, fill a shallow container with pre-moistened potting soil that has proper drainage. Space the cuttings a couple of inches apart, ensuring they have access to strong, filtered light. Keep the soil consistently moist, but be cautious not to overwater, as this can lead to fungal diseases.
After about 30 to 45 days, the cuttings should produce new sets of leaves. At this stage, it is important to harden off the rooted cuttings by gradually exposing them to increasing amounts of sunlight and outdoor temperatures. Once they have acclimated, transplant the cuttings to the garden, spacing them a couple of inches apart and covering the roots with soil.
Best Practices For Watering, Weeding, And Nutrient Management With Alfalfa
Watering alfalfa is essential for its growth and productivity. While alfalfa is generally drought-resistant, it benefits from ample water supply. During dry or hot weather, supplemental irrigation may be necessary. It is recommended to water at the soil line using a garden hose or watering can, avoiding overhead watering to prevent fungal diseases.
Weeding is crucial before planting and during the early growth stages of alfalfa to prevent unwanted weed establishment. However, it is important to avoid pulling weeds when the plants are shorter to prevent uprooting the young alfalfa plants. Keeping the beds free of weeds until the plants reach at least four or five inches tall will help them establish and grow without competition.
Proper nutrient management is key to ensuring the health and yield of alfalfa. Conducting a soil test to determine the pH and nutrient levels is highly recommended. The target pH for alfalfa is between 6.8 and 7.1. High-yield alfalfa requires potassium (K) levels between 150-170 parts per million (ppm) and phosphorous (P) levels between 25-30 ppm. Conducting NutriSolutions tissue tests can provide insights into sulfur (S) and boron (B) levels and enable better nutrient management.
By following these best practices for watering, weeding, and nutrient management, you can ensure the successful cultivation and harvest of alfalfa. Whether you are growing alfalfa as a cover crop, livestock feed, or for other purposes, proper care and management will lead to a thriving crop.
