Mercedes Onion Seeds
By Goddess's Seeds And Plants From Jamaica
The Texas Early Grano 502 PRR Onion has a uniform white flesh with a delicious eating quality! This onion variety produces a large globe shaped vidalia-type onion that has a nice flavor that is not too pungent. Texas Early Grano 502 PRR is a short day variety, but works well as an indeterminate day variety of onion as well. This onion also has a tolerance to pink root rot (PRR.) History: Texas Early Grano 502 PRR was released by the Texas Agricultural Experimental Station in 1944.
There are different kinds of onions, such as short-day onions which grow best in the south and long-day onions which grow best in northern climates.
Before Planting: Onions require full sun and fertile, well-drained soil with a pH of 6.0-7.0. Sandy loam soils with good moisture retention are recommended. Add some peat moss can help with moisture retention.
Watering: Onions are shallow rooted and grow best with at least 1? per week of rain or irrigation, especially during the bulbing phase.
Fertilizer: Upon planting, add compost to the soil, but since onions are heavy feeders they will grow best if fertilized throughout their growth. Also, add a timed-release granular 10-10-10 or 12-12-12 fertilizer to spread in the soil. Using a nitrate-based fertilizer will make the onions sweeter at harvest.
Days to Maturity: Onions are ready to harvest when the green tops flop over, but they can also be harvested quite early as green onions. For the full onion, once the tops flop over, wait for a dry day to complete the harvest. (See each variety for days to maturity)
Harvesting: When necks become soft and tops are falling over, pull and sun-cure at least 2-7 days, depending on weather. Move to a protected location to finish drying. When dry, clip off tops and roots and store in onion bags or shallow boxes at near freezing and 65-70% humidity.
Tips: Onion bulbing is triggered by day length, and maximum day length during the growing season increases from south to north.
