Every week, I get tons of questions about growing houseplants. In “Sheffield Answers”, I’m going to pick one out each week and answer it. Want to submit your own and get it featured next week? Click here to ask me a question!​

Question: Mr. S. I am getting brown spots on the only pink leaf on Pink Princess. Had her for 2 years, three new leaves coming out. Could it be a virus of some kind? What do I do? Mychelle

My Answer: I wouldn't be too worried about a virus. If your Pink Princess has been happily growing for two years and is now producing three new leaves, that's actually a very good sign that the plant is healthy overall. The pink parts of the leaves are much more delicate than the green areas because they contain very little chlorophyll, so they're often the first parts to develop brown spots as they age or if they've been exposed to a little too much direct sun, low humidity, or inconsistent watering. I'd keep caring for it as normal and pay more attention to the new growth than the damaged leaf. If the new leaves emerge looking healthy, there's very little reason for concern. Only if you start seeing distorted leaves, unusual mosaic-like patterns, or the whole plant begins to decline would I start thinking about something more serious.

🪴 LET'S TALK

​
There's now a hospital for houseplants

​
I spend a fair amount of time online looking at plant content, and I'll be honest with you, most of it makes me want to lie down.

​
Every week there's a new trend. Someone's putting a banana peel in the soil. Someone's swearing your Monstera won't fenestrate because you haven't been talking to it in the mornings. There's the endless parade of "10 plants that are IMPOSSIBLE to kill" lists, always the same ten plants, always slightly wrong. And there's a whole genre of video that's just someone gasping at a leaf.

You scroll. You sigh. You scroll on.

​
And then, every so often, something actually stops you.

​
There's a shop in Edinburgh called the Hilda Houseplant Hospital, and it is exactly what it sounds like. You bring in a poorly plant and it gets admitted. Some go on drips. Some go into quarantine. All of them get seen to by Rosanna Costello, who set it up because she remembered standing in a plant shop knowing roughly what to do but desperately wanting someone who knew better to just tell her.

​
The bit that got me is the process. When you bring a plant in, they take what she calls a "patient history." How long have you had it? What do you think is wrong?
​
What do you actually want to happen to it? Then it gets repotted, trimmed, treated, fed, cleaned up, and you get a phone call to say the surgery went well.

​
No trend. No hack. No secret ingredient from your fruit bowl. Just someone who knows what they're doing, looking at your actual plant, in the context of your actual home.

​
And one thing Rosanna said has stuck with me since. She talked about how much feeling and emotion people have wrapped up in these plants, and the relief and joy on their faces when they come to collect one that's been saved. Anyone who's ever nursed a plant back from the brink knows exactly what she means. It's never really about the plant.

​

​
So I want to know: would you use one? If there were a plant hospital down the road, would you hand over your struggling Calathea, or is that a bit like admitting defeat? Hit reply and let me know.

🪴 HOW TO & TIPS

​
The treatment nobody thinks to ask for

​
Right, but most of us don't live in Edinburgh.

​
So here's what I actually took from all this. The reason the hospital works isn't the drips or the fancy quarantine setup. It's that somebody sits down and asks proper questions before touching the plant. And the question that stopped me was the one Rosanna asks every single customer: what do you actually want to happen to it?

​
Split into two. Kept in one pot. Stopped from getting any bigger.

​
Read that list again. Every one of those is a propagation answer.

​
That's the bit I think most of us miss. We treat propagation as a hobby, a fun thing you do to a healthy plant on a Sunday because you fancy a free one. But half the time, propagation isn't a bonus. It's the treatment. It's the thing that fixes the plant you're currently staring at wondering whether to bin.

​
Here's what I mean.

​
The leggy one

​
You know the one. Stem stretching for the window, three sad leaves at the end, a foot of bare vine doing nothing. You've tried moving it. It's still leggy, because you can't un-stretch a stem.

​
You can't fix that plant. But you can cut the good bit off, root it, and put it back in the pot with the parent. Suddenly it's full again. Every plant person I know has a pothos that's been quietly rebuilt this way at least once, and mine's been through it twice.

​
The one that's outgrown your house

​
This is Rosanna's most common patient, the Monstera annexing the living room.
​
Her fix is a moss pole to train it up rather than out, and that's the right call if you want a big plant.

​
But if you don't? If you genuinely want it smaller? Then you cut it back and root the cuttings. That's not defeat, that's just choosing what you want. The plant lives on, it's just living on in three pots instead of one enormous one.

​
The one that's half dead

​
Root rot, a bad heatwave, an ambitious holiday. The bottom of the plant has gone, the roots are mush, and it looks finished.

​
Look at the top. If there's a firm stem with a node on it up there, the plant isn't finished, it's just relocating. Take the healthy growth, cut cleanly above a node, and start again. I've saved more plants with secateurs than I ever have with a watering can, and it's a strange feeling to accept that sometimes the kindest thing is to give up on the roots entirely.

​
The one you're scared of losing

​
This is the quiet one nobody talks about. If you've got a plant that means something, an inherited one, an expensive one, a variegated one you waited months for, the single best insurance policy is a cutting sitting in a jar on another shelf. Not because you expect to lose it. Because if you do, it isn't actually gone.

​
So: how to actually do it

​
Late July is genuinely the right moment for this. Everything is growing hard, warmth and light are doing half the work for you, and cuttings root faster now than they will at any other point in the year. Come autumn, growth slows and your success rate drops. This window is open now and it won't be for long.

​
The basics is find a node, cut clean (and just below it), pick your medium, change the water, and put up sooner than you think.
​

And then, the bit that ties back to the hospital: aftercare. A rooted cutting that goes straight back into the conditions that made the parent ill is a plant you'll be rescuing again by Christmas. Fix the light. Fix the watering. Then propagate.

​
A few things worth unlearning while you're at it

​
Rosanna shared some mistakes she sees constantly, and they're worth repeating precisely because they're so unglamorous. Nobody's making a viral video out of these:
​

• Ditch the "water once a week" routine. Pick the pot up. Your plant hasn't read your calendar. (Though in a heatwave, weekly might genuinely be about right.)
• Don't use outdoor compost on your houseplants. It doesn't drain freely enough, and it tends to arrive with a free gift of fungus gnats.
• Don't be scared to trim. It's a natural part of the growth cycle, the plant looks better for it, and you're removing places for pests to hide.

​
That last one is the whole thing, really. Most people's instinct when a plant looks poorly is to add something. Water, food, humidity, attention. Sometimes the answer is to take something away, and grow it into a new plant.

​
Reading about that hospital genuinely got under my skin a bit. Not because I think the shop is a bad idea, quite the opposite. But because so much of what walks through Rosanna's door is a plant that could have been split, cut back, or started again months earlier by the person who owns it, if they'd only known that was an option.

​
So I've done something about it. My Plant Propagation Workshop is going out at the equal biggest discount I've ever offered on it.

Did you know?

Every Granny Smith apple tree on earth is a clone. The original tree was a chance seedling in Maria Ann Smith's garden in Australia in the 1860s, and because apples don't grow true from seed, every single Granny Smith since has been propagated by cutting and grafting from that one plant. So when you're stood at the sink with a pothos cutting in a jam jar, you're doing the exact thing that built the global fruit industry. Same trick, smaller jar.
