National Trust’s Sky Garden Challenge 2026

You’ll be joining people who live in flats and apartments across the country doing exactly the same thing. Trying things out. Learning as they go. Sharing what works and what doesn’t.

Find out how you can take part and sign up to the Sky Garden Challenge. The competition is open until 16 August 2026.

You can grow loads of great plants in the smallest of spaces – flowers for bees, herbs, fruit or veg for you. You can start from seeds (get some free ones as part of the National Trust’s Sky Gardening Challenge) or buy some plants for instant impact.
