what to put under smart pots

A warning onusing smart pots

Just wanted to pass this along to others that use smart pots, or are considering them.

I’ve been really happy with my smart pots and have been using them for a couple of years.

However, do not place them on the ground in an area where the ground retains moisture. I found out the hard way that this is not a good idea. The soil in the pots could not dry out, and would actually wick the moisture out of the ground underneath them and cause the soil to be too moist. This encouraged root rot in several of my plants and killed them. Not good at all.

Next year I will be using the same pots, in the same location, but I will be placing a layer or two of rocks and rubble underneath them to encourage proper drainage. I may even use some drain pipe ( the kind with holes in it, like for a septic leach field ) to help keep the excess water from building up under them.

Just thought I would pass this on so others don’t make the same boo boo as I did.

lmao. I put mine inside a another pot where it would be taller,Well the plant started looking funny so i took it out of the other pot and there was a 3ft tap root in the bottom where when i watered it did not drain.

Plants dont like wet feet,either.

dont place smart pots on top of wood and even plastic, ive noticed roots will attempt to grow into wood very easily and get root bound quick causing root growth to stop, yes i know smart pots air prune roots but i wouldnt advise putting them on anything but instead get a larger pot and place em on top of eachother and use something like supersoil or you can even layer your amendments like guanos on the 2nd pot with high in Potassium and phosphorous and have your plant timed to grow into that pot when flowering, very effective.

if you can create a small 1×1 pvc pipe frame and use a strong nylon string and do criss crosses across it you can have your smart pot sit on that (make it strong) itll be most effective for air pruning, i also have used chicken wire with no problems but i am skeptical that metal will be absorbed or flaked onto the roots and you have to worry about rust depending on where you live.

Good ideas folks. Mine are outdoors, so when it rained and the soil got soaked the moisture could not leach out or drain due to it sitting on wet ground for so long. Even after a week after the rains quit the ground under the smart pot was still soaking wet, as was the soil in the pot. If I had put a layer of rocks, or drainrock or something down under the pots that would have kept the bottom dry then my plants would have done all right. Anything to keep them up out of the wet earth but still give good support.

Anyway, that s the plan for next year anyway.

Key Selling Points for Smart Pots: The Best Pots for Plants

As a consumer category, plant pots aren’t fundamentally different from any other durable good. When comparing products, customers seek maximum value — the biggest bang for their discretionary buck. And when it comes to gardening containers, maximum value unquestionably resides in Smart Pots. Let’s break down key points of differentiation that make Smart Pots the best pots for plants.

Room to Breathe:

Fabric Pots vs. Plastic Pots

Let’s start with the basics. Plastic pots have been in circulation since plastics became ubiquitous in consumer goods. In other words, they’ve been around awhile.

Plastic pots provide two distinct advantages. Namely, they’re cheap and lightweight. And that’s where the good news ends. Plastic pots have several distinct downsides that make them vastly inferior to fabric pots.

Start with moisture

As Isaac Newton famously observed, what goes up must come down. That goes for water flowing through soil, too. Water deposited at the surface is drawn by gravity to the base of the pot. Even if they have drain holes, plastic pots tend to let water accumulate near the bottom of the vessel. Pots without drain holes (and those sitting in drip trays) are even worse off.

That’s because overwatering is the single biggest killer of houseplants. Overwatering causes root rot, in part by starving roots of the oxygen they need to survive. When they’re drowning in oversaturated soil, roots can’t respire. So they die and biodegrade.

Overwatering invites a host of insect, bacterial and fungal pests that attack roots and make life miserable for plant owners. Ever suffered through an invasion of pesky fungus gnats? If so, overwatering was almost certainly to blame.

Now let’s talk about root circling. This is the real knockout punch in the battle of fabric pots vs. plastic pots. In a plastic pot, plant roots will eventually reach the boundary of the container. Once there, they begin circling the vessel in search of oxygen-rich soil. There’s just one problem. Plastic pots aren’t oxygen-permeable. So the roots grow to unhealthy proportions, getting tangled in the process. The result is a root-bound plant that is stressed or dying from lack of nutrition.

The Argument for Fabric Pots

Now, let’s examine why fabric makes the best pots for plants.

First up is moisture control. Fabric pots are permeable, meaning that water and air can pass into and out of the container. When water enters from the top, it permeates the soil and transpires from the sides of the pot. Excess water that reaches the bottom flows through the fabric and exits the vessel. This prevents excess moisture from building up in the container. Goodbye, root rot and overwatering.

Next up, oxygenation. As we learned before, roots need abundant oxygen to thrive. In fabric pots, oxygen flows through the container from all sides. When roots reach the container boundary, they sense optimum moisture and oxygen levels. The result is rather astounding.

When roots approach the edge of a fabric pot, they form dense, finely branched structures. Notably, they do not circle or become root-bound. The process, known as “air pruning,” produces fine root structures that are perfect for absorbing oxygen, moisture and nutrients. The result is not only a healthier root system, but a dramatically healthier plant.

Flowers grow more abundantly. Vegetable yields are off the charts. Plants grow bigger, denser and stronger. When comparing fabric pots vs. plastic pots, there really is no comparison.

Smart Pots: The Original Fabric Pot

Fabric containers were invented in the 1980s by High Caliper Growing of Oklahoma City, Oklahoma. Their flagship fabric container, known as the Smart Pot, is the world’s top-selling fabric pot. Over the years, the market has become flooded with knock-off products. So how do Smart Pots maintain their advantage? By being the world’s best pots for plants.

Here are just a few of the factors that put Smart Pots over the top:

  • They’re free of harsh chemicals and dyes that could leach into the soil.
  • They’re 100% BPA-free.
  • Every Smart Pot is made in the United States for unmatched quality control.
  • Smart Pots are scientifically designed to release heat, keeping roots healthy.
  • Smart Pots’ fabric is the perfect thickness to facilitate moisture control.
  • They are incredibly durable, lasting five years or more under normal conditions.
  • Smart Pots provide consistent quality from order to order, unlike foreign competitors.
  • Smart Pots are a scientifically proven product, and the world’s original fabric pot.

When you factor in plant health, vegetable yields, durability, safety, and quality, Smart Pots are the planet’s undisputed best pots for plants. At retailers around the world, customers ask for them by name. Put them on your shelves today and watch Smart Pots sell themselves.

When it comes to gardening containers, Smart Pots unquestionably provide maximum value. Let’s break down key points of differentiation.
