Lark F1 Sweetcorn Seeds

[83 days] Growing sweet corn in Britain used to be quite a challenge, and getting a good crop was even trickier. Lucky for us, a new breed of modern F1 varieties has been bred for our cooler climates, and that in includes the Extra Tender Super Sweet (or Tendersweet) Lark F1.

This easy-to-germinate, mid-season sweet corn produces two or three golden yellow cobs per plant, roughly 20cm (8”) long. Deliciously sweet, the fruit from Lark sweet corn tends to be more pleasurable to eat and easier to digest than traditional “supersweet” varieties.

Unlike most hybrids, the Lark F1 can be planted alongside other varieties and doesn’t need to be isolated. (Sow with Earlybird and Wagtail varieties to eat corn all season long!)

Eat sweet corn fresh or boiled, steamed and/or barbecued the cobs for a scrumptious treat. Height: 200cm (79”). Spread 45cm (18”).

What is eating my Lark F1 sweetcorn plants? Aphids and cutworms love eating Lark F1 sweetcorn plants and will destroy your crops quickly unless quickly removed.

How often should I water my Lark F1 sweetcorn? Lark F1 sweetcorn needs about an inch of water a week, especially once the stalks start to develop. Lack of water during pollination can cause kernels to fail to grow, so ensuring your corn is getting enough water is important.
