Container Size Matters

When I transplanted my geranium (Pelargonium) seedlings this spring I decided to conduct an experiment. I planted some seedlings into small 4 inch peat pots, some into 4 inch plastic pots, and some in into 6 inch plastic pots.I also potted one in a 2 inch clay pot.

When potted the seedlings were all the same size. But as you probably have guessed, they grew in relation to the size of container they were in. Those planted in larger containers grew larger. The plants in the peat pots were virtually stifled. This I am sure was because they dried out too quickly. The plant in the 2 inch clay did not thrive at all.

*It is important to note that the container size experiment will not work with every plant. Some plants prefer more confined growing conditions or companion planting. When transplanting houseplants the rule of thumb is to choose a container that is no more than 2 inches in diameter greater than the container the plant is currently in.
