Maythorn Garden Planner

Most garden apps guess your last frost from a map. Maythorn reads it from a weather station,
and tells you which one.

Set your garden's location and Maythorn finds the nearest national weather station with 30
years of daily records. You get the median last spring frost, the one-in-ten-year late frost
that careful gardeners plan against, and the first night warm enough for tomatoes and beans.
Every date carries its source: the station's name and how far it sits from your garden.

Where a country's records are not open for this, Maythorn says so. It will not show you a
date it cannot stand behind.

THE FROST WINDOW
• The median and the one-in-ten-year last frost, plus the warm-nights date, for each garden.
• Station name and distance stay on screen, so you can judge the number yourself.
• A coast station and an inland one can sit seven weeks apart. That gap is the point.

SOW AND PLANT NOW
• A month view of what is safe to start this week, crop by crop, from your station's dates
rather than a national average.
• The home screen carries the same answer in one line.

SEASON JOURNAL
• Sowed, potted on, planted out, harvested. Dates and notes, per bed or per plant.
• The notebook you already keep, in a form that survives the winter and the phone.

SEASONS SIDE BY SIDE
• When did the beans go out last year? Every crop you grew in more than one season lines up
in one grid: first sowing, planting out and first harvest, year against year.

YOUR GARDEN'S OWN FROST RECORD
• Log the frost nights you see yourself and Maythorn builds the measured record of your
garden: latest spring frost, first autumn frost, season after season.
• This works anywhere, including the countries whose station archives stay closed.

PERENNIALS AND FRUIT TREES
• Rhubarb, asparagus, apple, blackcurrant. The plants that stay in the ground for years,
kept beside the annual beds instead of in a second notebook.
• Each plant keeps its own page, season by season: when it was pruned, when it cropped.

ANY CROP
• Add a crop the catalog does not carry and it is tracked like the rest. No seed-shop lock-in.

EXPORT, ALWAYS FREE
• Your whole garden as a file, whenever you want it, in the free and the paid version alike.
