Notes:
NOTE: Corn Cold Testing As an additional service to our customers, all Johnny's treated sweet corn seed lots are "cold tested". We take this extra step to ensure our customers receive the highest germinating seeds possible. Cold testing mimics spring soil conditions and indicates suitability for early, cool soil sowing. FOR PACKAGE SIZES OF 5 LB. AND LARGER, SEED LOTS THAT GERMINATE BELOW OUR STANDARD IN THE COLD TEST ARE NEVER SHIPPED WITHOUT PRIOR CONSENT OF THE CUSTOMER.

Growing Information:
Corn, Sweet
CULTURE: Cold soil planting risks poor germination! Treated corn seeds (fungicide or Natural II) will not germinate below 55°F (13°C) and risk low germination under 60°F (16°C). Only treated seeds of good cold-germinating varieties may be sown in 55°F (13°C) or colder soil in anticipation of warming. Otherwise wait until soil temp. is at least 60°F (16°C). Make first sowings of UNTREATED seeds when soil is warm, at least 65°F (18°C).
PLANTING: Plan to separate small plantings of Super Sweets by a distance of 25 feet, (acreage plantings,100 feet) from non-Super Sweet varieties, or by time, a 10-day planting date/maturity difference. Extensive crossing with non-Super Sweets will result in tough, starchy kernels in both types. Sow 3/4-1" deep, 6-7" apart (or 2 seeds every 9", thinning to 1 plant), rows 30-36" apart. Increase this rate for untreated seeds. Arrange in blocks of at least 4 rows for proper pollination, which is needed for well-filled ears. Successive plantings can be made through early summer; most growers prefer to extend the sweet corn season by planting a few varieties of different maturities.
INSECT PESTS: Consult your local Extension office for Integrated Pest Management information. Reduce insect pests in the next corn crop by prompt plowing-in or removal and composting of cornstalks after harvest.
HARVEST: When kernels are full and "milky," generally indicated by a drying and browning of the ear silks. Record the date on which about half the plants show silk. Corn is ready to eat 18-24 days after ear silks first show; the warmer the weather, the sooner you can pick it.
DAYS TO MATURITY: Varies widely with weather conditions and planting dates. Use these figures to compare one variety to another, not to accurately predict maturity on a given day.
AVG. SEEDING RATE: 500'/M 2500'/5M 12500'/25M 30M/acre at 2 seeds/ft. in rows 36" apart.
SEED SPECS: SEEDS/LB.: 1,700-3,500 (avg. 2,500 su/se/synergistic type). Super Sweet 2,500-5,500 (avg. 3,000)
PACKET: 150 seeds sows 75' at 2 seeds/ft.
PLEASE SPECIFY: (1) treated with Natural II organic seed enhancement (B), (2) treated with fungicide seed protectants (T), or (3) untreated seeds. We offer most varieties untreated or Natural II treated for organic growers. All fungicide treated corn seeds are polymer-coated after treatment to prevent rubbing off or dusting of the treatment.
