About this deal
Variations in plant pot sizes can be quite different among individual nursery growers. While one nursery may ship a large, lush plant in a #1 pot, another might only send a bare, twiggy-looking plant in the same size. For this reason, you should research beforehand to make sure of what you are getting. Grade of Nursery Plant Pots This is one article in a series of four on container garden design. You can access the other three articles here: As the plants grow or mature, nursery growers may step up the plant to another larger size pot. For instance, a #1 shrub may be stepped up to a #3 pot.
Okay, as an example, if you’re told to use a 10” diameter pot, does that mean a 10” pot that holds approximately 1.3 gallons of soil, a 10” pot that holds 2 gallons, or a 10” pot that holds 3 gallons? All three are common sizes sold at nurseries and vary in volume capacity based on their other dimensions. What are trade gallons? If your container has no volume listed, you can figure out the volume by measuring the amount of soil you can put in it using your largest kitchen measuring tools.There are two basic ways to plant a combination. The “living flower arrangement” and the traditional planting. The living flower arrangement is when you place as many plants as possible into each planter. This allows the planter to look full immediately after planting. However, since living flower arrangements are crowded, they tend not to have as much longevity and often have more disease problems than traditional plantings. Living flower arrangements can be useful if you need to have a high impact container immediately, say for a party the same weekend you are planting the container. The gallon (4 L.) nursery containers, or #1 pots, are the most common nursery pot sizes used in the industry. While they normally only hold 3 quarts (3 L) of soil (using liquid measure), they are still considered to be 1-gallon (4 L.) pots. A variety of flowers, shrubs, and trees can be found in this pot size. Some pots may have their volume listed in measurements other than US customary units (gallons, etc.) and you can use our easy table or an online converter to figure it out.
Minimum recommended” size means you should try to use a pot at least that big, so if you can’t find that exact size just get a bigger one. Additionally, it’s possible to grow plants in “too small” pots, but your watering and fertilizing schedule will be much more demanding if you want healthy plants and a great harvest. In addition to the various pot sizes, some nursery growers include grading information. As with the variations among sizes, these too may vary among different growers. These are usually dependent on how a particular plant has been grown (its conditions). That said, the most common grades associated with plant pots are:
About Nursery Plants Pots
Now that we’re onto the trade gallons scheme, it must mean our predicament has been solved since everyone’s container size recommendations should mean “trade gallon” pots. Whew. That would mean if you’re supposed to use a “five gallon” nursery pot, your plant actually only needs the 3.55 regular gallons of soil that a 5 trade gallon pot should hold… wait… no!
Once you've added potting soil, it is time to start arranging the plants within the planter. It is best to leave an inch or two between the edge of the pot and the edge of the soil from the plants. This will give the plant room to root-out in all directions. From there you simply want to arrange the plants so each plant has some room and the whole planter will be filled. MoreUniversity Extension servicesused volume, but one office might say 1 gallon for peppers while others insist 5 gallons is the minimum. For tomatoes, extension offices recommended anywhere from 1-15 gallons.
What is #1 Pot Size?
As you are planting, try and spread the plants somewhat evenly throughout the planting area of the container while leaving some space between the edge of the container and the root ball of the plants. If you do that, your planters will look great. How about we turn to an old standby and look at bulletins and fact sheets released by land grant university Cooperative Extension services? After reading nearly two dozen of them from all over the country, Ilearned that… nobody agrees, even slightly, right down to whether it should be listed by pot volumes or pot diameters.
