I know, I know, you wouldn’t have thought people needed to search for this, but they do – and for good reason.
Sometimes plants pretend they’re dead when actually they’re just having a little rest or need a good drink.
Some plants just…look dead. I have a cactus that’s covered in dust and rabbit hair (it’s too spiky to clean!) and is scarred from an elongated mealy bug assault and it looks…dead. It’s not though, because it’s growing like hell.
Plant’s don’t breath or move (there are exceptions here) or have a heartbeat, so it’s not always possible to know if you’ve reached the end of the road.
Since starting this website, I’ve become really good at bringing plants back from the dead.
That sounds like a brag, but honestly, I should never have let them get to that stage in the first place.
Is a plant dead if all its leaves have fallen off?
Well, you’d think, wouldn’t you? Since plants need leaves to photosynthesise and stuff. Except their roots can do a sterling job of pushing out new growth when it’s time.
But no, plenty of plants go back into their tubers and shed all their leaves. Some don’t do this as a matter of course, rather they do it from neglect, in the hope that their owner will rehome them to someone more caring about their needs.
They can often still be revived from their root ball.
Some plants (Philodendron Gloriosum being an example) actually have their leaves removed prior to shipping, because they don’t travel well, and will be irreversibly damaged.
The plant may as well use its energy to keep its roots strong, rather than waste it on protecting leaves that are going to be damaged and will have to be snipped off anyway.
Some plants, such as cyclamen, die right back every year and can be revived back from their bulb. Unless you actually water yours too much and it rots, of course. Oops.
Last year, I had quite the spider mite infestation. I treated all the plants I THOUGHT had them but missed my jade plant. For some reason, I didn’t spot them.
All the leave fell off, other than the newest ones.
I left her alone over winter (she wouldn’t be growing anyway) and as soon as the weather warmed up, she went outside. Light is incredibly restorative to succulents, and she quickly (like, within 24 hours) starting showing signs of recovery.
If you look closely at the stem on the picture on the right, you can see new sprouts at the nodes. I’m fairly confident I’ll have it looking bushy and full in no time. The reason it looks a bit speckly and weird is that we had a TONNE of rain and it got overwatered.
I wouldn’t recommend overwatering cacti, but I had to make a choice between keeping it in the light and letting it become even leggier than it already was.
Is a plant dead if it gets root rot?
You can save plants from root rot but you have to act fast. In extreme situations (such as if repotting and leaving to dry out don’t work), you can perform surgery on your plant and snip off the mushy roots.
The root should be firm and usually white. If the roots are all brown, mushy and gross then it may be time to say your goodbyes. Snip off anything that grim and see if you can encourage regrowth.
Plants can grow back from surprisingly few roots, so don’t give up too soon.
Is a plant dying if it starts losing leaves?
Plants lose leaves as part of their natural cycle, so you need to look at
a) which leaf it’s lost and
b) how many leaves are dropping.
A single leaf turning brown and dying near the bottom of the plant is probably natural. If a plant is being watered inconsistently, then it may sacrifice either it’s the oldest leaf (usually one near the bottom) or the largest leaf.
If it’s just one, that’s cool. If it’s losing a lot of leaves in quick succession, you may have to swoop in an rescue it.
If you think that your plant has a pest infestation and the leaves are, not to put too fine a point on it, fucked, chop all the leaves off. It doesn’t work for all plants, but it’s a winner when it comes to getting rid of spider mites on Calathea.
Spider mites LOVE Calathea, and it can be hard to shift them. And I don’t want to point the finger at anyone in particular but CALATHEA ORNATA are the WORST for spider mites (Calathea Zebrina are the same but with thrips). They simply won’t go, and after while, pest treatments can start doing as much harm as the pests themselves.
Chop the leaves off. They’ll regrow, and hopefully you can stave of the pests next time. A lot of pests can live in the soil, but they won’t stick around if there aren’t any leaves to munch on.
Is a plant dead if its leaves start turning brown?
Not necessarily, but it can be a sign that your plant is dying. Brown leaves usually indicate underwatering, but I’d advise checking with a moisture metre. If your plant is already wet then you’ll just be killing it faster.
Brown leaves could also indicate sun damage, so check that your plant isn’t in full sun for a portion of the day.
It could also be a bacterial infection. Cut off the brown parts of the leaves, change the soil, spray it with neem oil and hope.
I have a whole post here on diagnosing why your plant’s leaves are turning brown. The article is specifically about Monstera deliciosa, but the causes of brown leaves are pretty much the same across the board.
Is a plant dead if its leaves start turning yellow?
Yellow leaves are likely to be a sign that your plant is being overwatered, so check the soil.
If it’s sodden, then check the roots and see if they’re mushy. then re-pot, perform surgery if required.
Yellowing or brown edges to leaves are usually a sign that you don’t have high enough humidity, so you may need to find a way to increase it.
Again, I have a whole post on this here. Also bout Monstera. I really have a type.
Telling the difference between a dead and a dormant plant
There are a couple of harsh ways to tell if a plant is dead or dormant:
- Select a stem and bend it. If it snaps, your plant is probably dead. If it’s reasonably pliable, it’s probably dormant
- Scratch the stem with something sharp. If the flesh underneath is green-tinged and damp, your plant is alive. If it’s dead, you’ll have a job even scratching it. Keep scratching your way down the stem, to see if the whole plant is dead, or just the ends.
- If you’re still unsure after performing both of these tests, then go back to checking the roots. If the roots are gone, the plant is gone.
If the stems are alive further down the plant, then snip off the dead parts. If part of a plant has gone completely brown it usually means the cells have died and can’t be revived.
Reviving a dying plant
There’s no secret to reviving a dying plant – just treat it nicely. Put it in a spot where it gets plenty of bright, indirect light and isn’t in a draught. Make sure it’s getting enough water but don’t overwater it. Don’t fertilise dying plants – the added chemicals may prove too much and be the final nail in the coffin.
Make sure you cut away any parts of the plant that aren’t serving it – any brown leaves can be snipped off, as can brown portions on leaves.
Don’t re-pot if you don’t have to. Re-potting a plant can place it under a lot of stress, which won’t help the situation.
Things to do if you suspect your plant is dying
- Google the plant. There may be something you’re not providing it with, such as enough light. Some plants can’t tolerate tap water, for example, so you may need to use rain or filtered water. You may discover that it’s just come to the of its life. I don’t know of any house plants that only live a year or so but you never know.
- Be vigilant about pests – they will attack a vulnerable plant. I had a Dieffenbachia that hadn’t been happy for ages (I still have no idea what I did wrong – I tried everything), but it was mealy bugs that finally killed it. Keep the plant clean using neem oil to ward off any unwanted critters.
- Don’t just water it. Water will not necessarily help a droopy plant – it might even be too much water making it droop.

Come on the article is prey helpful. That’s a bit harsh.
