Plant Yield Calculator For Pots, Planters, And Garden Containers

Before starting a container garden, you should know approximately how many vegetables your plants will produce. After a few calculations you will be able to determine how many pots you will need, how much soil and how many plants.

How Many Plants Can You Grow In a Pot?

Use the plant yield calculator to calculate how many vegetates grow in pots, planters, and garden containers. As a rule, a couple of 20-inch pots will grow enough greens for a family of four eating lettuce or spinach with a meal twice a week. The beauty of growing vegetables like greens is that once they are cut and harvested, they grow back for another harvest in just a couple of weeks. If you are growing tomatoes of peppers, each should have their own 20-inch pot otherwise plants would quickly become root bound and struggle to grow anything of any value.

How To Use The Plant Yield Calculator

If you are planning to grow vegetables in containers, the calculator below will calculate how many plants you can grow successfully in a pot. Simply choose the vegetable type in the first box and click: the number of plants you can grow in a 20-inch pot will display in the second box.

Growing Vegetables In Pots

Growing vegetables in pots can be challenging for most container gardeners due to designed space restrictions in each container. Garden containers are designed backwards with a shape opposite to the shape of the gathered roots of a plant, which grow naturally in a pyramid shape. An inverted pyramid shaped pot will constrict roots until they get “root bound.” Root bound plants become stunted and bear little fruit if any at all. To make matters worse, the soil at the top of the pot dries and hardens from the sun, shrinking away from the sides of the pot creating a gap. The hardened soil makes it impossible for water to soak into the soil so every time a plant is watered, the water will simply flow towards the gap, down the side of the pot and out before the plant has a chance to use it.

Round Pots: Problems And Challenges

Round garden pots, planters and garden containers can be a popular choice for container gardening, but they do come with some potential problems to consider:

  • Limited planting space: Round pots and planters have a smaller surface area than rectangular or square-shaped pots of the same volume, which means less planting space for your plants.
  • Uneven water distribution: Because the pot or garden container is round, the soil and plants can become unevenly moistened if the watering is not carefully managed.
  • Stability: Round planters can be less stable than rectangular or square-shaped garden planters, especially if they are tall and narrow. They may be more prone to tipping over in windy conditions or if they become top-heavy with growth.
  • Limited companion planting opportunities: If you are interested in companion planting or planting multiple varieties of plants in the same pot, a round pot may not offer enough space or soil volume to accommodate the growing of several plants together.
  • Challenging positioning: When positioning round garden containers, they can be more challenging to line up next to each other or to arrange in a visually appealing way.
  • Short plant life: Due to descending soil constraints typical of round pots, plants have a short life and quickly become root bound.
  • Poor yield: Containerized plants growing in round pots tend to produce significantly less than a plant grown in the garden.

Round pots generally work well for many types of plants, but it's important to consider these potential problems when deciding which type of pot to use for your container garden. If you are concerned about these issues, consider using a Crop Circle Garden Pot, which provides more planting space, more stability, longer plant life, bigger yields, and more opportunities for companion planting.

Crop Circle Garden Pots

Crop Circle Garden Pots, developed by New Leaf Technologies, are shaped to accommodate pyramidal shaped plant roots. It’s open-ended design permits roots to grow through the bottom of the pot when multiple, long-season plants are grown. This is a great feature if you are placing the pot in the yard or garden and want to create plant elevation for easy harvest.

Root bound is entirely eliminated, so plants will display uninterrupted growth with big full tops and bigger yields, more than plants would typically produce in the garden.

Encouraged to grow, plants quickly cover the soil at the open top of the pot protecting the soil from the sun. In this way, the soil never dries out and hardens. Water easily seeps down into the soil to reach even the deepest of plant roots. Soil stays loose and uncompacted comprised of hundreds of air pockets providing oxygen to stimulate plant growth.

Crop Circle Garden Pots can be accessorized to assist with watering, deck, patio, and rooftop placements. A 35-inch saucer covers soil at the bottom of the pot and collects excess water, protecting any surface the pot rests upon.

A Crop Circle Irrigator disperses water in a controlled manner using a drip line, or garden hose attachment that is connected to a water allotment timer.

A Tomato Volcano can be connected to the top of the pot to support the vining and weighted fruiting of tomatoes, cucumbers, and melons.

Cleanup is a cinch at the end of the season too. Simply cut the plants back at the top of the pot, grab the inside ledge with both hands and pull. The pot will easily lift off the formed soil mound that can be broken down and carted away.

For a comparison, use the calculator below to compare yield and production between similar plants growing in a typically shaped round garden pot and a Crop Circle Garden Pot.

Simply choose the vegetable type in the first box and click: the yield for each plant in both types of pots will display immediately.
