Planter Dimensions and Capacity
A 20 x 20 square planter has dimensions of 20 inches in length, 20 inches in width, and 20 inches in height. In centimeters, these dimensions translate to 50.8 centimeters in length, 50.8 centimeters in width, and 50.8 centimeters in height.
The volume of the planter can be calculated using the formula for the volume of a cube: Volume = length × width × height. Plugging in the dimensions, we get a volume of 8,000 cubic inches or 132,600 cubic centimeters.
The soil capacity of the planter depends on the type of soil used and the level of compaction. Assuming a soil density of 1.3 grams per cubic centimeter, the planter can hold approximately 172 kilograms of soil. The number of plants that can be accommodated in the planter depends on the size and root structure of the plants. Generally, a 20 x 20 square planter can accommodate 4-6 medium-sized plants or 6-8 small-sized plants.

Plant Selection and Care
When selecting plants for your 20 x 20 square planter, consider their height, spread, and sunlight requirements. Taller plants should be placed in the center, while shorter plants can be planted around the edges. Choose plants with a similar spread to avoid overcrowding. If your planter will be in a sunny location, select plants that can tolerate full sun. If your planter will be in a shady location, choose plants that can tolerate partial shade or full shade.
The ideal soil mix for plants in a 20 x 20 square planter is a well-draining potting mix. You can purchase a pre-mixed potting mix or make your own by mixing equal parts peat moss, perlite, and vermiculite. Water your plants deeply and regularly, especially during hot weather. Fertilize your plants monthly with a balanced fertilizer.
Companion planting is a great way to maximize space and enhance plant growth. When companion planting, choose plants that have different nutrient needs and root depths. For example, you could plant tomatoes (which are heavy feeders) with basil (which has shallow roots). The basil will help to repel pests and improve the flavor of the tomatoes.
