Are you looking to add a delightful touch to your garden or edible landscape? Consider growing black raspberries. Not only are they easy to cultivate, but they also offer a rewarding experience. Let’s explore how you can successfully grow black raspberries in your small-scale garden or landscape.

The Permaculture Inspired Edible Landscape

“Black Raspberry Plants Free to a Good Home” – that message caught my eye on the neighborhood message board many years ago. Intrigued, I quickly responded, excited about expanding my collection of fruiting plants in the edible landscape. Little did I know that this simple act would lead to new friendships and a bountiful harvest.

Black raspberries are incredibly adaptable to various growing conditions, making them a perfect addition to any garden. If you’re ready to embark on the journey of growing black raspberries, let’s explore the steps together.

Planting Black Raspberries

To ensure the healthy growth of black raspberries, consider planting them in USDA hardiness zones 5-8. Although they are not as hardy as red or yellow varieties, you can still try growing them in zone 4, preferably on the north side of a building or slope to protect them from spring frost and wind damage.

When selecting a location, choose a spot that receives full sun or partial shade. In hotter climates, providing them with some shade during the late afternoon can benefit their growth.

Keep in mind that it’s best to avoid planting black raspberries near wild raspberries or blackberries, as they can transmit diseases. Maintain a minimum distance of 300 feet between them.

Black raspberries are self-pollinating, meaning you only need one plant to enjoy a fruitful harvest. Additionally, they thrive in well-drained soil, so make sure to select a location that avoids excessive moisture. Prior to planting, enrich the soil by incorporating compost or manure, and repeat this process every spring.

Space your black raspberry canes approximately 2-1/2 feet apart in a row. This spacing allows easy access to both sides of the row for harvesting, training, and pruning. To prevent the plants from becoming unruly, install a trellis or fence during the planting process.

Cultivating Black Raspberries in the Edible Landscape

Black raspberries are not only delicious but also visually striking. Their vibrant red canes breathe life into gray winters, while the evolving colors of the ripening berries bring cheer to early summer. These qualities make them a perfect fit for any edible landscape.

You might wonder if there’s any difference between growing red and black raspberries. While both are delightful berries, they behave differently in terms of growth and spread. Unlike red raspberries that spread through suckers, black raspberries tend to stay in one place. They only generate new plants when their canes bend and touch the ground.

This behavior is easy to manage through proper pruning. It’s worth noting that red and yellow raspberries, as well as thornless blackberries, are better suited for gardeners with more space, allowing for larger rows of wandering canes. Thus, black raspberries are a preferable choice for smaller garden spaces and front yard landscapes.

If the idea of incorporating fruit crops into your landscape intrigues you, consider black raspberries as a foundational planting. Here’s why they are an excellent choice:

  1. Their height typically stays within 2 1/2 – 4 feet, assuming proper pruning.
  2. The thorny nature of black raspberries provides added security near windows.
  3. They are easy to train in a straight line, simplifying maintenance.
  4. Black raspberries exhibit beauty throughout both winter and summer.
  5. They remain in a fixed location, eliminating concerns about spreading.
  6. These berries thrive in areas with partial shade, making them adaptable to overshadowed locations.
  7. Black raspberries are juglone tolerant and can be planted near black walnut trees.

Coexisting with Wildlife

1: Birds and Black Raspberries

One of the challenges of growing black raspberries is keeping the birds from devouring them. These feathered friends have a particular affinity for the berries. To deter them, you can try bird netting or shiny objects like old CDs. However, I’ve discovered an unusual method that might yield better results.

Pruning the canes to a shorter height, around 2-1/2 to 3 feet, reduces the accessibility of the berries to birds. This height also safeguards against neighborhood predators, such as cats, which pose a threat to the raspberries. Pruning our black raspberries to a height of four feet allows the birds to feast while Molly, our farm cat, is unable to reach the berries. I plan to experiment with even shorter pruning heights in the future to gauge the impact.

2: Deer and Black Raspberries

If deer are a common visitor to your neighborhood, growing black raspberries may present a challenge unless you’re willing to protect your crop with a garden deer fence. Otherwise, they might devour the entire plant, not just the berries.

Alternatively, you can create a “fedge” (a food hedge), which acts as a barrier between wildlife and your garden. A fedge is a densely planted hedge that deters deer by offering an abundant food source on the outside. By confusing their depth perception, the fedge convinces deer to stay on the outer side rather than venturing into your garden. Keep in mind that this strategy requires a significant amount of space, with the fedge being approximately six feet wide on both sides.

Harvesting the Bounty

To maximize your black raspberry harvest, it’s crucial to train and prune the plants correctly. Proper pruning not only enhances the health of the canes but also makes it easier to pick the ripe berries without getting pricked by thorns.

During the first year of planting, don’t expect a significant harvest. It’s in the second year that you’ll begin reaping a handful of berries from each hill. By the third year and beyond, you can anticipate a bountiful harvest, ranging from two to six quarts per hill. Factors such as wildlife deterrent strategies and sun exposure (more sun equals a larger harvest) can influence the yield.

Each black raspberry variety has its own ripening season, typically falling into the categories of early, mid-, or late season. Knowing the specific ripening schedule of your chosen variety allows you to plan accordingly. For instance, our black raspberries ripen in June, which means we avoid scheduling vacations during that time to ensure a successful harvest.

When black raspberries reach the perfect level of ripeness, they transition from bright red to deep purple. During this period, it’s essential to harvest daily to outpace wildlife that are equally eager to enjoy the fruits of your labor.

Exploring Culinary Delights

The versatility of black raspberries extends beyond their appeal as fresh-picked treats. You can freeze them to enjoy throughout the winter or incorporate them into various culinary creations. Whether you prefer them in smoothies, baked goods, over vanilla ice cream, or in jellies, black raspberries add a burst of flavor to any dish.

So, are you ready to embrace the joy of growing black raspberries? Whether you’re a seasoned gardener or new to cultivating your own food, these delectable fruits are a fantastic addition to any garden or edible landscape.
