PlantAssure Sub-Irrigation System

(163 customer reviews)



A PLANTZ exclusive.  Our PlantAssure sub-irrigation system is designed to extend your plant’s watering interval, often times allowing plants to go several weeks to a month between waterings.  The kit is sized to the growpot of your plant, and raises the growpot above the liner creating a reservoir from which the plant draws water as the soil dries down.  Each kit includes 1) one PVC ring of approximately 6″ or 8″ in diameter that will raise the growpot approximately 1″ off the bottom of the liner, and 2) four wicks made of capillary matting material that absorb water from the reservoir into the soil profile.

When a PlantAssure kit is ordered with a new plant from us, the plant will be delivered to you with the wicks installed and you will incur no additional shipping costs.  You will simply place the plant on top of the PVC ring in the liner and push the wicks down in to the bottom of the liner where it will come in contact with the water when you water the plant.

Please note that liners are NOT included with the system if it is purchased without a plant but any local garden center should have these.  You should measure the diameter of the base of the plant and purchase one locally that is slightly larger.

You can order the PlantAssure kits separately and install them yourself on your existing plants or plants from other sources.

    I’m yet to see how this works. I understand it in theory, but my first plant was frozen in transport, so I am yet to watch this work. I am slightly concerned that the water will start to smell stagnant. We will see!

    • Sue Waltzer (verified owner)

      The plant should be using up the water regularly so you can wait until the liner has dried down before adding fresh water. It should extend the watering intervals since there is more water for the plant to use and not sit until the water is stagnant.

    • Sue Waltzer (verified owner)

      This was installed in the plant for you. The white capillary wicks are protruding from the growpot holes at the base of the plant and the riser ring is in the liner under the plant. I’ll give you a call to make sure you have it and have gotten my care instructions too!

    Great system, although I need a flashlight to see what’s going on inside my larger decorative planter.

    • Sue Waltzer (verified owner)

      Measuring and dating will help you with this once the plant has settled in. It takes about 4 weeks for them to settle down.

    A bit pricey for what it is…pebbles could also raise the growpot to allow drainage and air circulation around the roots.

    • Sue Waltzer (verified owner)

      The system is more about the capillary wicks than the riser but we try to make it easier for customer by adding the riser which is the perfect height and a bit easier to use than pebbles.

  61. William R. (verified owner)

    The PlantAssure Kit is a great innovation which solves the over or under watering problem that plant novices have.

    Our palm is healthy – more importantly, even though I’m a novice at keeping houseplants, I am stress free and literally never worry about over or under watering. Very simple to use, and the instructions and videos from the Plantz team were great. Even if I didn’t love the customer service (and I do), I would choose Plantz for all my future houseplant needs because of the simplicity and peace of mind that come from the irrigation system.

    If you are one who is not sure about watering (I’ve learned the hard way how important it is to get it right) you need to get this. Just do it.

    • Sue Waltzer (verified owner)

      Getting it on a watering schedule is the most important thing! I think we’ve all killed a few plants by overwatering!

  82. Daniel (verified owner)

    The idea here is great, but a few things could improve it, I think: 1) the ring could be slightly bigger, so the plant sits more firmly atop it, and 2) instructions could indicate that water is supposed to come up to the _bottoms_ of the growpot’s holes, not above that.

    • Sue Waltzer (verified owner)

      Thanks for the notes. I think we state in a few places that the water stays below the holes where the wicks are protruding but I’ll highlight this in my emails going forward.
      Thank you!

      Hi Melissa – Unfortunately, we don’t have any control over FedEx and their pricing. I wish we did! We try to get customers to add supplies when they order the plant so we can include everything in the same box and there is no additional shipping charges. We do try to get our rates lower on a regular basis but so far, FedEx isn’t being very flexible!

    I purchased 2 other plants and those get a 5 rating. They did super through the delivery. More than all of this, I want to commend you on your outstanding customer service. Sue was the person I dealt with the entire time. She was amazing to work with. She followed the delivery, provided instructions, and then followed up to see how things were coming along. I will recommend you guys to anyone that wants some amazing plants. I look forward to ordering some for myself at home now. Thanks so much Sue Waltzer. Your amazing!
