Beans can go in
The soil has averaged above 12 °C over the week, and no night at 2 °C or below is forecast for ten days. Sow any colder and the seed sits in the ground and rots.
LOAM PRONothing left to remember
Your garden, remembered.
When to sow the carrots, when the tomatoes go out, when to sow radishes again — and when did you sow them, anyway? Loam keeps it all for you. Every morning it tells you what to do in the garden, from your own soil, and why; every job you tick off is logged.

Why it works
Your spring, not the average spring.
A mild March can open the bean window eleven days early; a cold one pushes it into May. Loam knows what your soil usually does at this time of year, then corrects it with what the weather is actually doing — so your dates move with the season instead of ignoring it.
A seed feels the soil, not the air
One warm afternoon means nothing six centimetres down. Loam reads the soil at sowing depth, over the past week — the temperature your seeds are really sitting in.
Your garden, not your region
Frost settles on the valley floor and misses the slope above it. Loam works from the spot you point to, close enough to tell them apart — and it never keeps your address.
Every crop has its own numbers
Beans wait for 12 °C. Lettuce is sown between 8 and 22 °C. Fifty-three crops, each with the figures growers actually use.
Example: bush beans near Lyon, soil temperature at sowing depth. Your own garden reads its own numbers.
Getting started
Three steps, under a minute.
Point to your garden
Tap the map, roughly where you grow. No account, no email, no address to type in.
Pick your crops
Fifty-three vegetables and herbs. Loam already knows what each one needs from the soil, and what cold and heat do to it. Already sown, planted or bought as plants, each picks up where it stands. Five of them on the free plan.
Open Today
Two or three things to do, in order, each with the reason behind it. Tick one off and the next moves up. It opens out in the garden, signal or not — and the widget puts them on your home screen.
What you get
It tells you before you think to ask.
Every job reaches your phone on its day, on its own. Each one names the crop, the number and what to do about it.
Sow radishes again
Twelve days since the last row, and the window is still open. A short row every twelve days is what keeps them coming instead of arriving all at once.
LOAM PROEarth up the leeks
A month after planting, then every month: soil drawn up round the stems keeps them white. Thinning, earthing up, mulching, netting: every care of every crop comes on its day, counted from the sowing or the planting.
LOAM PROWater the zucchini
Loam counts the rain that fell on your garden, the waterings you logged and the rain forecast, by how much each crop drinks. If rain is due tomorrow, it waits; in a pot or a heatwave, it doesn’t.
LOAM PRO34 °C tomorrow
Tomatoes stop setting fruit above 32 °C. Shade in the morning and water at the root — the fruit already set is fine.

CLOSEDOPENCLOSINGDELAYEDHouse rules
Three things Loam will not do.
Advise without a number
Never “conditions are favourable”. Always the soil is at 13 °C and beans need 12 °C. You decide with the same figure Loam decided on.
Sow by the calendar
Loam has no sowing calendar. A mild March opens the window early, a cold one pushes it back — wherever you garden, and whatever the packet says.
Guess when it doesn’t know
If the weather for your garden is more than 12 hours old, no window is shown open and no alert goes out. Loam says so plainly instead of guessing.
The catalogue
Fifty-three crops, each with its own numbers.
Annual vegetables and herbs, from sowing to harvest. Every one arrives with the warmth it needs to germinate, the cold it survives and the heat that stops it — the numbers seed houses and gardeners go by, not a lab’s.
