Growing Info
Harvesting: Sweet corn is ready about 3 weeks after the silks appear. Harvest when the silks are brown, but not dried, and the husks are dark green; ears should be plump, and rounded rather than pointed at the tip. To test for ripeness, gently pull back the husk and pop a kernel; the liquid should be whitish; if it is still clear, ears are not quite ready.
Special Care: Keep area weeded, especially when plants are young and have shallow roots. To guarantee good pollination, gently shake the tassels to release the pollen onto the silks. You can also hand pollinate by pulling off a tassel from one plant and wiping it on the silks of several ears. If you notice "skips" or blank spaces on an ear where a kernel should be, that is an indication of inadequate pollination.

Thank you for taking the time to share your experience with the Ambrosia Sweet Corn Seeds. We're sorry to hear that you only got a small harvest from your planting—that's definitely disappointing when you're looking forward to enjoying fresh corn.
Sweet corn yield can be affected by several factors including planting density, soil conditions, watering, and pollination. Corn benefits from being planted in blocks rather than single rows to improve pollination, and consistent moisture is key for good ear development. Growing conditions and timing can really impact the final harvest size.
We appreciate you giving the Ambrosia variety a try and sharing your growing experience with other gardeners. Your feedback helps us understand how our seeds perform in different conditions. Keep on growing 🌻️

This was the sweetest, best-tasting corn I’ve ever grown! I’m in zone 5/6 and it was more like “waist high by the 4th of July”. I’m back for more seed for 2025!

Interestingly, I just picked the first ears not more than 20-minutes ago. They are perfect. We’ll be roasting them as part of dinner tonite. More to come.
