The easiest, and most beautifully designed water meter we've ever used.
Designed and made in Japan, Sustee makes it simple to know when to water your plant. Sustee's window is blue when your plants have enough water and turns white when it's time to water your plants. It's so simple!
Sustee is different from other moisture meters. It detects your plant's ability to absorb water, not how much water is in the soil, so it works in all kinds of soils and plants.
How to Use
1. Insert Sustee into the soil, within a 20 cm radius of your plant.
2. Ensure that it's deep enough so that the surface of the soil is between the two arrows marked on the meter. ▶◀
3. Water your plant generously the first time. This will activate your Sustee and it will turn blue.
4. When Sustee turns white, it's time to water again. Follow the usual watering amount for the plant and the meter will turn blue again.
FAQ
Does SUSTEE work for different types of plants?
Yes, it does! There is a beneficial soil moisture range shared by all plants. It's called "available water capacity", which works as a common denominator for moisture management for all plants, preventing them from root rot and drying up.
Sustee helps you to water the right way to maintain this beneficial moisture range.
How long does it take SUSTEE to change colour after watering?
It depends on the amount of water given and the water retention level. The periods given below are rough guides. With some soils it can take up to an hour. Remember to water generously when you use SUSTEE for the first time.
Size Small: Approx. 3 minutes
Size Medium: Approx. 15 minutes
Size Large: Approx. 25 minutes

Let customers speak for us
from 662 reviewsI was at the store in Aug 15. They were short staffed but the one woman who was doing everything was very kind, patient, and knowledgeable. I always recommend Frondly to all my plant killer friends.
Lovely rubber plant was delivered, free, in a timely manner. Would refer others to the store.
Thank you!
Heard that the shop have to shut down for a few days due to building structure. No doubt have to support Chad coz i always got lovely plants from Frondly. The plants I received always so healthy and packed with sophisticated care.
I recently visited Frondly Plants for the first time, and I was extremely impressed. I don’t know the name of the person who helped me, but she was fantastic. She was warm and pleasant, clearly very knowledgeable, and gave me excellent advice. She also did a wonderful job repotting my Japanese fern into a larger pot.
I was particularly impressed by the quality of the plants throughout the store. Everything looked exceptionally healthy and well cared for, and there were so many beautiful plants that I would have been happy taking almost any one of them home.
My Japanese fern is doing very well in its new pot, and I absolutely love it.
The combination of knowledgeable, friendly service and such high-quality plants made my first visit a terrific experience. I can and will highly recommend Frondly Plants to friends and family looking for beautiful, healthy indoor plants and genuinely excellent service.
I will definitely be back.
Sincerely,

What a treasure! They expertly replanted some of my ageing plants into either my own pots or the new ones I bought from them, and lots of advice on care!

I’ve placed two orders from Frondly, both times the plants arrived well packaged, and all plants were beautiful and healthy! 10/10 ⭐️
I love that I can save my soil bag and bring it in for discounted refills. It’s great soil and a great way to encourage less plastic waste and customer loyalty.
