‘Ashworth’ yellow sweet corn, certified organic seeds

Zea mays

Product code : GAIAS-0274

Heirloom yellow sweet corn producing 6-to-7-inch ears on 5-to-6-foot stalks. Early variety maturing in 69 to 72 days. Read the packet directions before starting and keep the label so the variety remains clearly identified throughout the season. Prepare a clean, loose, well-drained growing medium and moisten it before placing the seeds so they are not displaced by the first watering. Keep the seedbed evenly moist without standing water because excess moisture reduces air around developing roots. Move seedlings into bright light as soon as they emerge and rotate containers regularly to encourage balanced growth. Where several seedlings compete for the same space, thin carefully and retain the strongest plants without disturbing their roots.

‘Ashworth’ yellow sweet corn, certified organic seeds (Zea mays) Ashworth is an early variety producing 6-to-7-inch yellow ears on stalks approximately 5 to 6 feet tall. Its 69-to-72-day maturity suits relatively short seasons and provides fresh sweet corn quickly. This annual open-pollinated heirloom can be saved for seed when plants are isolated from other corn. The packet contains approximately 50 seeds certified organic by Ecocert Canada. Sweet kernels suit boiling, steaming, grilling, or roasting and are best enjoyed soon after harvest for maximum sweetness and dependable short-season garden performance overall.

Direct sow 1 to 2 inches deep when soil reaches approximately 19°C and all frost risk has passed. An optional soak in warm water for up to 12 hours may speed water uptake; sow immediately afterward into warm soil that is not waterlogged. Germination generally takes 5 to 8 days. Space plants 8 to 10 inches apart and rows 24 to 36 inches apart. For reliable wind pollination, plant several short rows in a block instead of one long row, then keep nearby weeds from competing with young plants.

Grow Ashworth in full sun and deep fertile soil rich in organic matter with good drainage. Maintain even moisture while tassels, silks, and ears are forming. Corn uses substantial nitrogen, so incorporate compost and provide feeding appropriate to soil fertility. This crop is frost tender and should not be described as hardy to −5°C. Harvest when silks are brown and dry and kernels are plump; a pierced kernel should release milky liquid. Cool ears quickly after harvest and use them within a few days because their sugars gradually convert to starch.

How to use it

Uses in the garden

Plant Ashworth in a block of several short rows for wind pollination. Place the block north of shorter crops to limit shade. If other corn grows nearby, separate flowering times or distance plantings to preserve eating quality and keep saved seed true to type. Read the packet directions before starting and keep the label so the variety remains clearly identified throughout the season. Prepare a clean, loose, well-drained growing medium and moisten it before placing the seeds so they are not displaced by the first watering. Keep the seedbed evenly moist without standing water because excess moisture reduces air around developing roots. Move seedlings into bright light as soon as they emerge and rotate containers regularly to encourage balanced growth. Where several seedlings compete for the same space, thin carefully and retain the strongest plants without disturbing their roots. Before outdoor planting, gradually acclimatize young plants to wind, sunlight, and changing temperatures over several days. Follow the stated spacing so air can move between plants and each plant receives adequate light, water, and nutrients. Water at soil level when the surface begins to dry, then adjust frequency for weather, drainage, and container volume.
