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

As always, Frondly delivers on its promises of healthy plants, timely delivery, and the improvement of the living space. This is one of my favorite places to shop.
Everyone who works here is absolutely lovely. Maybe it's the plants, maybe it's the vibes, maybe it's just good management. Either way, the people who work here truly are some of the nicest, most patient individuals I have come across, and as someone with a certified black thumb, I appreciate them so very much. (The plants are great, too! Totally recommend!)
I love Frondly, chilled delivery guy, helpful. Sad that my plant Charlotte is bad maybe its me. But my other plants are awesome. My cats are chilled with them even thou my plants are pet friendly. I am looking forward to buying more!! First time plant mama.
I always got the help that I needed, and also walked away with new plants as well.
Knowledgeable and beautifully presented store. Great quality plants.
