My Garden: Free Garden Journal & Care Reminders

Why does keeping a garden journal make you a better gardener?

My Garden is a free garden journal online — a plant care tracker for everything you grow, with notes, harvest logs and plant watering reminders. Think of it as a free garden diary that remembers the watering days for you, so nothing depends on memory. Add plants straight from the plant finder.

Gardening runs on a one-year feedback loop: by the time you learn whether a decision was right, the season is over and the details are gone. A journal shortens that loop from memory to record.

When each plant has a dated photo timeline and a few notes, next season’s questions stop being guesses: Which tomato variety actually cropped first? When did the aphids arrive last year? How long did that lettuce bed really last before bolting? Farmers and researchers formalise this as phenology — tracking the dates of recurring biological events like first flowering, fruit set and last harvest — and it is the backbone of how planting calendars were built in the first place. Your journal is a phenology record for the one microclimate no calendar can model: your own garden.

There are two quieter benefits. First, photos catch problems early — leaf yellowing, pest damage and nutrient deficiencies are far easier to spot when this week’s photo sits next to last week’s. Second, a “grown 43 days” timeline is motivating in a way memory never is; seeing progress is what keeps new gardeners going through the slow weeks. The journal here is deliberately low-friction: one photo and an optional note per entry, attached to a plant you have saved, viewable as a timeline from anywhere — because a journal only works if it actually gets written.

How do the care reminders use real weather — and why do they skip rainy days?

Most reminder apps run a dumb countdown: “water every 3 days”, rain or shine. That teaches overwatering — the number-one killer of garden and container plants. The reminders here are computed differently, every day, from three inputs:

• The plant’s real water need. Each saved plant carries its species’ water requirement from the plant database — a drought-happy rosemary and a thirsty basil are never put on the same clock.
• The season. Water demand follows evapotranspiration — the combined loss of water from soil and leaves — which rises with heat and sun. Intervals stretch automatically in cool months and tighten in summer.
• Live local weather, including rain. Before a watering email is sent, the day’s forecast for your location is checked. If meaningful rain is expected, the reminder is skipped — the sky is doing the job, and watering on top of rain does nothing but leach nutrients and invite root rot.

The result lands as a plain email — no app install, no notification permissions, nothing to charge. You can opt out per account at any time, and the reminder maths restarts automatically as the weather changes. It is the same weather-aware logic subscription plant-care apps sell as their premium tier, running free in your inbox.

Why track harvest value? The money your garden quietly saves

Ask a gardener whether the garden “pays for itself” and you’ll get a shrug — almost nobody measures it. Yet the classic finding of home-garden economics studies (the best-known US example valued a well-run vegetable garden’s annual produce in the hundreds of dollars over its costs) is that ordinary gardens genuinely out-earn what is spent on seed and compost. The catch is that the value arrives in dozens of small, forgettable harvests: a bowl of beans here, three tomatoes there.

The harvest log turns those forgettable moments into a running total. Log what you pick and its weight; the tracker keeps a season sum and an estimated shop-price value, so “a few tomatoes now and then” becomes “9.4 kg of tomatoes — roughly what a supermarket would have charged for them”. That number does three useful things:

• It guides next year’s plan. Sort a season by value and the verdict is obvious: herbs, salad leaves and cherry tomatoes usually repay their space many times over, while space-hungry, cheap-to-buy crops (looking at you, maincrop potatoes) may not deserve a prime bed.
• It makes the case for the garden. A real figure — kilograms picked, money saved — is the honest answer to “is all that digging worth it?”
• It closes the loop with the journal. Harvest entries sit alongside the photo timeline, so each plant’s record runs seed → growth → yield: the complete story of what worked.

What does the unified My Garden dashboard show at a glance?

Once you are logged in, /my-garden/ works as a single control room for everything you track on Gardening Guider. The top of the page answers the only question that matters each morning — “what does my garden need today?” — by computing which plants are due for watering from each plant’s stored water need, the current season and your live local forecast (rainy days are flagged so you can skip the can). Below that, every saved plant gets its own profile card that pulls together its latest journal note, its most recent harvest and its care status, so you never have to hop between three tools to see one plant’s story.

A stats strip keeps the season honest — plants saved, journal entries, kilograms harvested and the estimated money your garden has saved you — and a milestone row marks the small wins (first plant, first harvest, $50 saved) that make the habit stick. When the season winds down, the “Share my season” button turns those numbers into a ready-to-post recap image, generated right in your browser. All of it is free, and all of it runs on the data you have already entered — nothing extra to maintain.

Getting started with My Garden in 30 seconds

1. Save a plant. Add it from any care guide or from the plant finder.
2. Log what you do. My Garden keeps watering, feeding and harvest notes in one place.
3. Check the today list. It shows only what actually needs care.

Find new plants with the plant finder, name unknown ones with the plant identifier, and design the beds in the garden planner. Watering amounts come from the water calculator.
