GardenWhen nothing is wrong
Live · This works today.
Yellow bottom leaves, tops flopping over, and skin going dry and papery are three things that look like a plant failing and are usually a plant finishing. A card appears when one of them is expected for that crop at that exact point in its year, and the card leads with what the plant is actually doing rather than the words don't worry. Sometimes that sign is not a shrug but a starting pistol — on garlic, onions and potatoes the same yellowing leaves are the signal to dig — and then the card says that instead.
Sometimes it is not "nothing to do" — it is "go now"
The same sign can be a shrug on one plant and a deadline on another, and the difference is what the plant is doing at that moment. Yellow bottom leaves on an asparagus bed heading into winter mean it is stocking its roots and there is genuinely nothing to do. The same yellow leaves on garlic mean the bulb is finished and it is time to dig.
Where the sign is not expected for that crop and stage, the card stays away and the question becomes an ordinary diagnosis — which is what the guides are for. They differ by crop more than people expect: the list of things that turn a tomato leaf yellow is not the list for a cucumber, where the commonest serious cause makes patches with straight edges that stop at the veins.
So on the crops where the sign is the harvest signal — garlic, onions, shallots, potatoes, sweet potatoes, winter squash and others — the card says Ready rather than Nothing wrong, and gives you the deadline instead of reassurance. Garlic left much past that point splits its wrapper and stores badly, so the difference is a real one.
We got this wrong the first time. The card told you the yellow leaves were nothing to worry about while the app’s own to-do list was saying “harvest garlic” — the same plant, the same screen, two different answers. What the app knows is that the sign is expected at that stage; expected is not the same as fine, and it took another pair of eyes to spot that we had read one as the other.
The plant is not dying, it is finishing
Three things a healthy plant does look, to a new gardener, exactly like a plant giving up.
The bottom leaves go yellow and limp. The tops flop over on the ground. The outside goes dry and papery. Every one of those is on the list of things people search in a panic, and every one of them is, on the right crop at the right time, the plant doing precisely what it is supposed to do.
So when GardenTrack can see that is what is happening, it says so.
Why the card leads with the reason
The first version of this said “this is normal” on the front and hid the reason behind a tap. That was backwards, and Nik said so: if you tell somebody everything is fine and they do not know why, they do not feel any better.
He is right. Being told not to worry is not reassurance. Knowing what the plant is doing is.
So the line under the headline is the mechanism — the plant is emptying out its oldest, least useful leaves and putting what it gets back into finishing the crop. Once you know that, the yellow leaf makes sense. You can see the same thing next week and stay calm without us, which is the whole idea.
The same sign means opposite things on different plants
This is the part that is genuinely hard to work out alone, and it is why an app can help.
Yellowing lower leaves on a tomato that is still growing is a sign worth looking into. The identical yellow on a garlic that is curing, an asparagus bed going dormant, or a sweet potato ready to dig is the plant finishing correctly. Same symptom. Opposite meaning. The difference is which plant it is and where it is in its year — and the app knows both of those things about your garden.
A plant going dormant gets a different explanation from a plant ripening a crop, too. A dormant asparagus bed is not pushing anything into fruit; it is pulling everything back down into its roots to live on over winter. Telling somebody the wrong reason undoes the card.
What stops it reassuring you about a real problem
Three things, and they are worth being plain about.
It only speaks when our record for that crop lists that sign as expected at the stage the plant is in now. Not generally, not usually — at this point in this plant's year.
It never speaks about a sign the app is flagging at the same time. If anything else in GardenTrack is telling you to look into that sign, this card does not appear. One card saying “this is normal” next to another saying “look into this” would be worse than either on its own.
And it always tells you what would make it not normal. If the yellow climbs up into the new growth at the top, or arrives with spots or a smell, that is a different thing and we want to hear about it. If the tops went over early, before anything had bulked up underneath, that is usually wind or rot rather than ripeness. Reassurance you cannot check is just being patted on the head.
Telling it you looked
The app could always record that you found a pest, or a disease. It had no way to record the thing that actually happens most days — you went out, you looked, everything was fine. So a plant’s history could only read as a list of problems, and nothing could answer “when did I last actually look at this?”
Now it can. Confirming this card records it, and every plant has a Looked it over — all fine button whether or not a card is showing. The plant’s page tells you when you last did: you looked this over 3 days ago and it was fine, or nobody has looked this over yet, which are deliberately different sentences — one is a plant you have not gotten around to, the other is a plant you are losing track of.
It expires, and that is the important part. Fine on the 5th says nothing about the 20th. After about a week it stops counting as current; after two the page says it is worth another look, and anything the app went quiet about comes back on its own. You never have to remember to un-silence anything.
We also changed a button label because it was lying. It used to say Good to know and quietly saved an inspection — and “good to know” is what you tap to clear a card from the sofa, having looked at nothing. It says Yes, that is what I see now, which is a sentence you can only answer standing at the plant.
Common questions
- If nothing is wrong, does it actually say so?
- Yes, in those words, at the top of the answer — **"Nothing is wrong with it"** — and then what the thing you were looking at actually is. Speckling on an apple, for instance, comes back as nothing wrong, and underneath, that the marks are normal lenticel dotting. **You get the verdict and the reason, in that order**, because being told you are fine without being told why is not reassuring; you just go and look again tomorrow. There is a third answer as well: it can say it cannot tell whether anything is wrong. That is different from not knowing which problem it is, and it means go and take a closer photo rather than assume either way.
- Why does the app tell me nothing is wrong? I did not ask.
- Because about half of the true answers about a garden are that nothing is wrong, and nobody was saying them. A gardener sees yellow leaves at the bottom of a plant and starts looking for a disease. If that plant is a sweet potato in August, the yellow is the plant emptying its oldest leaves into the crop, and the right move is to do nothing. That is worth saying out loud.
- What are the three things it fires on?
- Bottom leaves going yellow, tops flopping over on the ground, and skin going dry and papery. Those three look like a plant dying to anyone who has not seen them before. It does not fire on things nobody panics about — a first flower is lovely and does not need a card.
- Why not a bolting stalk? That looks alarming too.
- It does, and we did include it at first. But a parsley plant throwing up a flower stalk is expected AND unwelcome — it is the exact moment the leaves stop being worth picking. Calling that normal is true and useless. It is a good example of the mistake we made across this whole feature: expected is not the same as fine.
- Does it just say everything is fine?
- No, and that is the point. A cheerful all-clear is worth nothing. The card names the exact thing you are looking at, says what the plant is doing, and then says where the same sign WOULD be worth a look — on that same crop, earlier in its year. That last line comes out of the crop's own record, not out of a wish to sound comforting.
- Could it tell me nothing is wrong when something really is?
- That is the risk we built around, so here is how it is limited. The card only appears for a crop where our record says that sign is expected at the stage the plant is in right now. It never appears for a sign we are flagging at the same time. And it will not say nothing-to-do when the plant is actually due to be picked — if the app has a harvest or a curing job for that plant, the card gives you the deadline instead. That last one we got wrong at first and had to fix. Every card also says what would make it not normal, so you have something to check rather than a promise.
- Yellow bottom leaves on my tomato got a warning, not this card. Why?
- Because on a growing tomato that is not expected — it is one of the signs worth looking into, and our record says so. On a curing garlic or a dormant asparagus bed the same yellow is the plant working. Same symptom, opposite meaning, and which one it is depends on the plant and where it is in its year. That is the thing you genuinely cannot work out on your own, so it is the thing the app should be doing.
- What happens when I tap "Yes, that is what I see"?
- It records that you looked at that plant on that day and it was fine, and the plant's page starts showing when you last did. The button used to say Good to know, which was wrong of us — that is what people tap to clear a card without looking at anything, and it was writing an inspection into your journal that had not happened. The label now says the thing it records. On a plant that is ready to pick you get a different button, because the card is a deadline there, not a shrug.
- Does "it was fine" last forever?
- No, and that is on purpose. Fine on the 5th says nothing about the 20th — aphids turn up in three days. A check counts as current for about a week and goes stale after two, and then your plant page says it is worth another look. An app that treated one tap as permanent would quietly stop watching a plant that later got sick, and you would have no way of knowing it had stopped.
- What if I tap it and then it gets worse?
- Tap the other button — it looks worse than that — and tell us what you are seeing, or send a photo. Nothing about the card stops you reporting it, and a card being wrong about your plant is worth more to us than a card nobody argued with.
- Where did the yellow-leaf explanation come from?
- University of Wisconsin Extension, on a page titled Analyzing Reasons for Yellow Leaves — plants get rid of older, unproductive leaves in favor of new growth. We link it on the card. This one mattered enough to check rather than write from memory, because almost everything published about yellow leaves is about disease, and a confident explanation that talked somebody out of a real infection would be the worst thing this card could do.
