Frequently Asked Questions (FAQs)

What does "25M SDS" mean?
"25M" denotes 25,000 seeds ("M" is the standard seed industry abbreviation for thousands). "SDS" stands for Standard Diameter Seeds, meaning the seeds have been mechanically graded to a highly uniform size, ensuring they flow flawlessly through standard precision mechanical seeders.
Is the seed pre-treated?
Yes. All premium commercial seed from Terranova Seeds comes standard with specialized treatments and protective coatings. This shields the delicate seedling during initial germination against early dampening-off diseases and soil-borne pests. [1, 2, 3]
What day-length type is Malbec?
Malbec is a Short-Day to early Intermediate onion variety. It is specifically bred to trigger bulb formation when day lengths reach 11 to 12 hours, making it highly effective for warm-season, tropical highland, and early-spring production climates. [1, 2, 3, 4, 5]
How well does this variety store?
For an ultra-early short-day red onion, Malbec features strong neck closure and a tough double-skin layer, offering good medium-term storage potential. However, because it is an early-maturing variety designed primarily to capture premium fresh-market pricing window advantages, its storage lifecycle is shorter than late long-day storage varieties. [1, 2, 3]
What are the soil conditions required?
While Malbec demonstrates enhanced vigor and genetic tolerance to common root rot pressures, growers should always practice proper crop rotation and avoid soils heavily contaminated with structural Pink Root fungal blocks to ensure top yields. [1]
