Planting raspberry plants in a container can help you save space in your garden. The right raspberry container should be the proper depth and width so that the plant has enough room to spread. You may choose from a variety of materials, which differ in price, durability, and practicality. The pot design should allow you easy access to the bush while preventing standing water inside the container.
A raspberry container should be at least 8 to 10 inches (20.32 to 25.4 cm) deep to allow the roots to expand downward. If you use a deeper container, you may want to partially fill the pot with dirt before planting raspberries. This is so the roots are not buried too deeply and therefore unable to absorb water. The diameter of this container should be at least 15 inches (38.1 cm) wide if growing one raspberry bush or at least 3 feet (0.92 m) wide if planting two bushes inside it.
Terra cotta and clay containers normally absorb more sunlight that plastic or vinyl ones do. This could make them an ideal choice if the area they are located in receives minimal sunlight. Clay and terra cotta might also be more expensive than other varieties are. A plastic raspberry container is less likely to break than clay pottery would if it is tipped over. Concrete containers are not likely to fall over in high winds, but they might be cumbersome to move from location to another since they are normally very heavy.
The rim of a raspberry container should be narrow because one that is extremely wide could make it difficult for you to reach inside the pot. It is also helpful if the rim does not slope outward, as this could also make it awkward to care for the bushes. Some containers sit on a pillar, preventing the need to stoop or kneel when trimming the raspberry plants. One that has a trellis on the back can be a good idea because you can train the shrub to grow vertically. This might protect you from being scratched by the plant's briars when fertilizing the berries.
It can be important for a raspberry container to have drainage holes in the bottom. The roots can develop disease if they become waterlogged. There should be at least one hole every 2 to 3 inches (5.08 to 7.24 cm) along the bottom for best results.
