How to calculate spacing between plants? ›

For a square bed, multiply the length of the bed by its width to determine how many plants per square foot. For a circular planting bed, you can calculate how many plants per square foot is ideal by multiplying 3.14 by the distance from the center to the edge of the bed.

The easy way to determine spacing between different plants is to use the average of their mature sizes. As an example, when planting a 5-foot-wide hydrangea planted next to a boxwood that grows up to 3 feet wide, space the plants 4 feet apart. Remember to measure from the center of one plant to the next.

Finding the square footage of a square or rectangular area of land. Multiply the length by the width to determine the square footage—or area—of a square or rectangle. Find the square footage by multiplying the length and width of the area in question. Make sure to keep your units the same (feet or inches).

In landscape plantings for hedges, shrubs are generally spaced 3-5 feet apart. To create a tree hedge (maybe to mark a property line), space trees 8-10 feet apart for deciduous trees and about 10 feet apart for evergreen trees.

Square foot gardening is an efficient and space-saving technique that involves dividing your garden into small, manageable squares. Each square is typically one foot by one foot and is planted with a specific number of plants depending on their size.

A general recommendation is to place tomato plants about 18-24 inches apart, but plant spacing actually depends a lot on the type of tomato variety you're planting. Research the variety or follow spacing guidelines on the seed packet or plant tag.

A typical 10'x10' garden space you could grow the following: 3 indeterminate tomatoes or two tomatoes and 1 cucumber on a trellis. 4 eggplants. 5 peppers.

Space the plants 12 inches apart. If you plant cucumbers on a raised garden bed, mulching is a good way to keep the soil moist and increase yield. Cucumbers like light, airy coverings, such as straw or crushed leaves. Avoid using anything too dense, which may suffocate the plant.

What is the on center plant spacing? ›

Sometimes this is referred to as "on-center" or "o.c." spacing. On-center refers to the distance between the center of one plant and the next.

Define the length l and width w of the surface to be planted. Adjust these values with the eventual border. Define the spacing between plants. Divide the values of l and w by the spacing, round the results, and add 1 to each result to find the number of rows and columns of plants.

The formula for planting is simple: one extra-large plant per 1x1-foot square, four large plants per square, nine medium plants per square, and 16 small plants per square.

The ideal spacing between the rows in your garden provides ample room for your plants to grow and for you to work in. In most cases it is a good idea to leave at least 18 to 36 inches of space between each row of plants.

Many plants, such as shrubs and round-headed trees, grow about as wide as they grow tall. If figures for width can not be found, estimate from the ultimate height. A plant that may grow somewhere between 5 and 10 feet tall might be planted about 7 to 8 feet apart.

In general, plants with known positive relationships should be planted within two or three rows of each other. Plants that have negative or detrimental relationships, should be planted at least two to three rows apart. Infestation of pests or disease can occur more quickly if you plant all the same crop close together.
