How Much Potting Soil for Trough Planter

Many people love the idea of having a garden but don't have the space to do so. A trough planter is an ideal solution for those who want to grow plants in a small space. Trough planters are long, narrow containers designed to hold soil for growing various types of plants. One of the most important factors in successfully growing plants in a trough planter is soil. In this article, we'll discuss how much potting soil you'll need for your trough planter.

The Size of Your Trough Planter

The size of your trough planter will determine how much soil you'll need to fill it. To determine the size of your planter, measure the length, width, and height. Multiply these numbers together to get the volume of your trough planter in cubic feet. This measurement will give you an idea of how much potting soil you'll need to fill the trough planter.

How Much Potting Soil Do You Need?

For most trough planters, you'll need approximately one cubic foot of potting soil for every foot of the planter. For example, if your trough planter is five feet long, you'll need approximately five cubic feet of soil to fill it. However, it's important to note that this estimate is not always exact, and the amount of soil you need may vary depending on several factors.

Factors Affecting How Much Potting Soil You'll Need

Several factors can affect how much potting soil you'll need for your trough planter. Here are a few things to consider:

The size of your plants - If you plan on growing large plants that require more soil to thrive, you'll need to add more potting soil to your trough planter.

The type of plants - Different types of plants require different amounts of soil. For example, shallow-rooted plants need less soil than those with deep roots.

The depth of your planter - The deeper your trough planter, the more soil you'll need to fill it.

The type of potting soil - Different brands and types of potting soil have different densities, which can affect how much you need to use.

Calculating the Exact Amount of Potting Soil You'll Need

If you want to calculate the exact amount of potting soil you'll need for your trough planter, follow these steps:

Measure the length, width, and height of your trough planter in inches.

Convert the measurements to feet by dividing each by 12.

Multiply the length, width, and height in feet to get the volume of your trough planter in cubic feet.

Multiply the volume by the density of your potting soil to get the weight of soil needed. The density of potting soil varies but is typically between 0.5 and 1.0 grams per cubic centimeter or 0.5 to 1.0 kilograms per liter.

It's always a good idea to purchase a little extra potting soil, just in case you need to top off your planter or add soil for newly planted seeds.
