The hidden cost of plant care.

  • It's expensive

    The average Brit spends £50-150 per year replacing plants.

  • It's unneccessary

    Your plants should last for years, all they need is good care.

  • You're already paying

    It's not a bargain plant if you have to buy them every few months.

  • It feels rubbish

    Build confidence and feel proud of your plants, not guilty about them.

Invest in yourself and your plants.

The perfect plant purchase to stop the others from being a waste.

Trusted by real people.

The 'click' when the probe connects to the sensor is extremely satisfying!"

We measure everything your plants need

Overwatering. Underwatering. The two biggest killers of houseplants.

SmartyPlants senses when the balance is off and guides you with gentle, clear prompts. No guessing. No stress.

Too much, too little - light levels can be tricky to get right.

We measure brightness and duration to help you find the perfect spot for every plant in your home.

Even subtle shifts can impact growth.

SmartyPlants tracks temperature changes throughout the day, helping protect sensitive plants from overnight chills or drafts.

Air that's too dry or too damp can hold plants back.

We help you maintain healthy humidity levels season to season, preventing yellowing leaves and keeping your plants looking their best.

Healthy soil, healthy plants.

Our sensors monitor nutrient levels so your pants have everything they need - never too much, never too little.

Your questions, answered

Yes - the SmartyPlants app is free to download and use.

Everything you need to keep your plants thriving comes with your sensor.

Yes - SmartyPlants supports all kinds of indoor plants, from low-light ferns to sun-loving succulents.

It's designed for houseplants of every shape and style, helping each one find its perfect balance.

Not always. One sensor can guide care for several plants with similar needs.

If similar plants share the same light or humidity, one sensor gives insights for all.

For varied collections, adding an extra or two helps keep everything balanced, which is why we offer bundle options.

SmartyPlants starts learning straight away.

From the moment it's in the soil, the sensor reads moisture, light, temperature, humidity and nutrients. It'll spot anything that needs attention right away.

Over time, it builds a fuller picture of your plant's environment to further tailor insights.
