Why is container growing so great?
· You can better control the soil
· You can move the plant to the sun, shade or garage
· It’s not permanent and you can try growing something new
· They’re best for nursery grown plants since any diseased plantings will be restricted to the pot instead of contaminating your in-ground garden soil
What is a downside to it?
· Your garden can look junky and overcrowded if there are too many pots
Which containers are best?
That depends on your purpose for the container. Is it going to be for decorative plantings such as annual or perennial flowers or for growing herbs, fruit or vegetables?
As you may recall, I am growing the Double Gold raspberry in an Earthbox.
Earthbox—I’ve grown tomatoes, strawberries, loose leaf lettuce and raspberries in these. I find the strawberries do not survive the winter in them. I prefer to use them for raspberries and loose leaf lettuce because of their length and water containment.
· Earthbox has a water containing compartment in the bottom of the container. Unlike other ‘self-watering’ containers, I like that Earthbox has an overflow hole in case of over-watering.
· An Earthbox is heavy to move. But the Earthbox set comes with wheels, which is great if you plan to use it on a hard surface.
· Earthbox is a growing system, but I find that you easily lose the nice plastic covering you’re supposed to poke your plants through.
Smart Pots—Fabric pots that air-prune the roots. When the roots reach the fabric and the air on the other side, they stop growing and form fibrous roots.
Fibrous roots are the ones that gather the most nutrients from the soil. Your plants never become root-bound and develop a fuller root system. They were originally designed for use in tree nurseries.
I’ve grown flowers, tomatoes, herbs, strawberries, blueberries, raspberries and fruit trees in them. Above are photos of tomatoes and mint growing in Smart Pots.
· A Smart Pot forms a capillary action with the dirt ground beneath it which helps to keep the pot from drying out. Eventually, the roots may grow through the bottom to the dirt below. No problem, just rotate your pot and break that minor growth.
· They are lightweight and easy to move. You can move your pot to follow the sunny spots in your garden or to bring it into the garage in the winter.
· Many sizes. I’ve used 3 gal, 5 gal and 7 gal pots. Please note that as the size increases they tend to get wider rather than taller.
· Temperature regulation. The fabric keeps the pot from overheating.
· You can put them inside decorative pots.
I have a decorative urn in my garden. It gets too warm in the sun and hardly anything will thrive in it. I’ve put a Smart Pot inside the urn and planted flowers that will flow over the edge of the urn—masking the edges of the Smart Pot—and the plants now survive better.
I would recommend trying a Smart Pot. You can purchase them from Amazon. Here is a link to an Amazon seller who sells them in a pack of 5.
The only disadvantage to a Smart Pot is what I refer to as becoming ‘root-full.’ Instead of being root-bound, it grows so many fibrous roots that all the untapped soil becomes occupied and then the soil becomes compacted.
Think of it like this: the roots now outweigh the soil.
This may be a problem with my Jelly Bean blueberry bush. When watering Jelly Bean, the water would run down the side of the fabric pot instead of being absorbed into the soil.
I think this can be avoided by planting a bush in which the root ball is NOT nearly the same size as the container. Therefore, the roots have more room to grow.
And it can be solved by re-potting to a larger container or by root-pruning. I’ll write more about this later this month.
