Which plants pair well with Sweet corn?

Cantaloupe, Cucumber, Edamame, Lettuce, Pumpkin

How fast do I get my plan?

Three steps, three minutes. Type your location, measure your bed, click the veg you like. I do the rest.

Free: one bed, full annual plan, PDF export — free and no account needed. Pro (multiple beds + weather + garden calendar + push & email reminders): €4.90/month or €39/year. Premium (with AI coach Stachi): €9.90/month or €79/year.

Does it work for a balcony planter?

Yes. From a 40×20 cm balcony box to a 3×1 m raised bed — same three steps, same outcome.

Do I need an account?

Not for your first plan — creating one works without signing in. You'll need an account once you want multiple beds, your plan on multiple devices, or weather reminders.

Seed & start

Stachi's tip

Sweet corn needs warmth, water and patience. Plant in a block (min. 3×3 rows) not a single row — wind needs to distribute pollen. Classic three-sisters partner to bean and squash.
