Cucumber plants are vining plants that can be successfully grown in containers. Cucumber plants that are grown in containers can produce as many cucumbers as those in a garden bed. The different growing conditions, type of container used and the type of cucumber will affect the size of the container that you need.
As a general rule, having a larger sized container for your cucumber plant is better than having a smaller sized container. Choose a container that is a minimum of 16 inches deep to ensure enough room for your cucumber plant's roots. If your container is a minimum of 22 inches wide, you will have room for a stake inside the container, to give extra support to your cucumber plant. Choosing a specific container that is appropriately sized will be determined by several factors.
The type of material for the pot or container that will house the cucumber plant will greatly affect the required size for the cucumber plant. This is particularly true if you are planning on growing your container cucumber plant outdoors. The material of the container will determine how easily the container will heat up in the sunlight. Neutral colours and ceramics will be the least heat conductive, while thin, plastic and dark coloured materials will conduct heat the most, making it more likely that your plant will overheat. If you use a darker coloured pot, choose a larger size so that the soil will be able to stay cooler.
Type of Cucumber
The type of cucumber will affect how large your container size should be. Dwarf cucumber plants can be grown successfully in a smaller sized container. However, regular sized cucumber plants will require a larger sized container as they will require more room for their root structure, and will need more nutrients, and thus more soil.
If you grow your cucumber plant indoors or on a patio, space restrictions will play a large part in deciding the size of container. However, the smaller the container, the easier the plant can overheat. As well, a smaller container may mean more frequent waterings as the container and the amount of soil can retain less water than a larger container which can hold more soil.
