Grow Your Own Container Grown Blackberries: All You Need to Know

Container Grown Blackberries – The Basics

Are you looking for a way to grow blackberries in a small space or without having to dig up your garden? If so, container grown blackberries may be just what you need. Blackberries are delicious and nutritious, packed with vitamins and antioxidants, and they are relatively easy to grow. However, traditional methods of growing blackberries require a lot of space and maintenance.

That’s where container grown blackberries come in. Growing blackberries in containers is an excellent option for those who want to grow this tasty fruit but don’t have the space or time to tend to a large garden. In this article, we’ll discuss everything you need to know about growing blackberries in containers.

Choosing the Right Container

Size Matters

The first thing you need to consider when choosing a container for your blackberries is its size. Blackberries have deep roots, so you will need a container that is at least 18 inches deep. The width of the container should also be at least 18 inches to provide enough room for the roots to spread out. Avoid using smaller containers, as they won't provide enough space for the plant to grow and thrive.

Type of Container

You can use any type of container to grow blackberries, as long as it has drainage holes. Plastic pots are lightweight and easy to move around, while terracotta pots are more porous and allow for better air flow to the roots. The material you choose largely depends on your personal preference and the conditions in your area.

Choosing the Right Soil

Light and Loose Soil

Blackberries thrive in well-draining soil that is rich in organic matter. Use a potting mix that is specifically designed for containers and has a light, loose texture. You can also add perlite or vermiculite to improve drainage and aeration.

pH Level

The pH level of the soil should be between 5.5 and 6.5 for optimal growth. You can test the pH level of the soil using a soil testing kit, which you can find at most garden centers or online. If the pH level is too high or low, you can adjust it by adding lime or sulfur to the soil.

Planting Blackberry Bushes

When to Plant

Plant blackberry bushes in containers in late winter or early spring, when the weather is cool but not freezing. You can also plant in the fall if you live in a mild climate.

Spacing

Space the plants at least 3 feet apart to allow enough room for growth. If you are planting multiple blackberry bushes, space them at least 4 to 5 feet apart.

Watering

Water the blackberry plants immediately after planting and keep the soil moist but not waterlogged. The frequency of watering will depend on the climate and the size of the container.

Caring for Container Grown Blackberries

Fertilizing

Feed the blackberry plants with a balanced fertilizer, such as a 10-10-10 or 20-20-20 formula, every four to six weeks during the growing season. Don't fertilize in the fall or winter, as this can encourage new growth that will be damaged by frost.

Pruning

Prune the blackberry plants in late winter or early spring before new growth begins. Remove any dead or damaged canes and trim back the remaining canes by about a third of their length.

Pest Control

Blackberries are susceptible to a number of pests, including aphids, spider mites, and raspberry fruitworms. You can control these pests by spraying the plants with insecticidal soap or neem oil. Be sure to follow the instructions on the label carefully.

Harvesting Container Grown Blackberries

When to Harvest

Blackberries are typically ready to harvest in mid to late summer, depending on the variety and climate. The berries should be plump, shiny, and completely black. If they are still red or purple, they are not yet ripe.

How to Harvest

Harvest the berries by gently pulling them off the plant. Be careful not to crush or bruise the berries, as they are delicate and can spoil easily. Once you have harvested all the ripe berries, refrigerate them immediately.

Common Problems with Container Grown Blackberries

Root Rot

Root rot is a common problem with container grown blackberries, particularly if the soil is too wet. To prevent root rot, make sure the pot has adequate drainage and don't overwater the plants.

Dry Soil

Dry soil is another common problem for container grown blackberries. Make sure the soil stays moist but not waterlogged, and water the plants regularly.

Fungal Diseases

Blackberries are susceptible to a number of fungal diseases, such as anthracnose and powdery mildew. To prevent these diseases, keep the plants well-ventilated and avoid overhead watering.
