New WS L550 Alfalfa (w/Apex™ Green)

WS L550 Alfalfa (w/Apex™ Green) is a new branch-rooted alfalfa with High Resistance to Aphanomyces Root Rot 2.
WS L550 was bred for high quality, superior yieldability and fast recover after harvest.
WS L550 has a high expression of the branch root feature, making WSL550 very persistent in both well and poorly drained soils.

WS L550 alfalfa is an untreated/non-gmo alfalfa pre-inoculated and coated with an OMRI Listed inoculant and coating for improved establishment and growth.
Inoculation is recommended when planting legumes.
*Details on Seed Coatings, Inoculations & our OMRI Certificate are available on our Reference Page.


Plant Alfalfa at 1/4″ depth in a soil bed that is moist, fertile and firm and at least 1/2″ depth on sandy soils.
Alfalfa prefers crumbly silt loam to sandy loam textures, but alfalfa will grow well on most deep, well-drained soils with adequate internal and surface drainage.
The pH level for alfalfa should be 6.5-7.2.
Alfalfa may be planted in spring or early fall.

*Do not harvest alfalfa seeded in late summer/early fall until the following spring.
*Alfalfa will die if the soil is saturated for an extended period.


For maximum yields, it is important to have 20-30 plants per square foot during the seedling year for protection against weed competition.
Apply lime and fertilizer as needed.
Alfalfa is a heavy Potash user, some micronutrient supplements would be beneficial (boron, sulfur, zinc).
First year seedings should be cut at 25% bloom..
Cut alfalfa three-four times a year from budding to full flower, depending on forage quality needed.
The last cutting or grazing of Alfalfa should be 4 weeks before the killing frost.
