Although they are robust plants that thrive in cold weather, boysenberries require a little winter protection in chilly climates.
Plants prefer an organically-rich, well-draining soil, with a pH of 6.0-7.0. Keeping your plants cool in hot temperatures is important, so if you live somewhere warm, provide your boysenberries with partial shade during the day, and mulch with a light-colored material.
The boysenberry was developed in the early 1920s by horticulturist Rudolph Boysen of Anaheim, California, who later turned it over to farmer Walter Knott for commercial development (see Knott's Berry Farm).

Small, yellow spots on leaves are the first signs of orange rust, a fungal disease. Eventually, they grow into pustules that produce orange spores. Fruit rot. This occurs when the ripening fruit rots on the canes.
It can withstand some frost, but only if that frost comes after the plant has had a chance to realize that the days are growing shorter and cooler, activating cold acclimation in the plant. For boysenberries, acclimation can only take them so far.
Mulch with Straw Hands down, the best type of mulch for boysenberry plants is straw. Best of all, the straw breaks down relatively quickly. If you mulch with it each year, your soil will absorb nutrients that keep it rich and healthy.
Somewhat surprisingly, the biggest national producer and exporter of boysenberries is New Zealand. The berry is also grown commercially in the US in parts of Oregon and California. And of course, home gardeners can grow the berry in any location that falls in USDA Hardiness…
Flowering: Boysenberries flower in spring, they are self-pollinated but bees will help to increase yields. Care: Tie stems to training wires or trellis as they grow. Keep plants open and ensure good airflow – especially in warmer areas where humidity can result in fungal diseases…
First, while boysenberry roots are perennial, the plant sends up new biennial canes, or stems, each year. First-year canes, called primocanes, are green and produce only leaves, not fruit. But the boysenberry plant will continue to produce new primocanes each year with no prompting from…
You will know a boysenberry is ripe when it is dark purple, plump, and shiny. After the berries are harvested at the end of summer, the vines will need to be pruned. Boysenberry plants go dormant in winter, but they will be back next spring,…
When growing a boysenberry plant, select a site in full sun with well-draining, sandy loam soil that has a pH of 5.8-6.5. Plant boysenberry plants 4 weeks before your area's last frost date. Dig a hole 1-2 feet (30.5-61 cm.) deep and 3-4 feet (about…

Boysenberries are harvested when the fruits drop from the vine at the slightest touch. For best results, plant boysenberries in well-drained, slightly acidic soil in full sun. Self-pollinating. Zones 5-10.
Keep the plants evenly moist, but not wet; water at the base of the plant rather than overhead to avoid leaf disease and fruit rot. Feed boysenberries with a 20-20-20 application of fertilizer in the early spring as new growth appears. Fish meal and blood…
Symptoms may first be noticed in spring to early summer as small purple spots on new shoots or spots with purple margins. Spots will grow larger, take on a more oval shape, and turn gray as the disease progresses. Eventually, infected canes will die back.
Boysenberry plants need a full sun location, with six to eight hours of sunshine per day. Plants prefer an organically-rich, well-draining soil, with a pH of 6.0-7.0. When you set out your transplants you can fertilize with 20-20-20 (NPK), according to package instructions, or mix…
Fertilize the boysenberries with a 20-20-20 mix (nitrogen, phosphorus, potassium) at the beginning of spring and then every 4 weeks after that. Remember to till in the fertilizer and then re-mulch the soil each time.
The boysenberry /ˈbɔɪzənbɛri/ is a cross among the European raspberry (Rubus idaeus), European blackberry (Rubus fruticosus), American dewberry (Rubus aboriginum), and loganberry (Rubus × loganobaccus). It is a large 8.0-gram (0.28 oz) aggregate fruit, with large seeds and a deep maroon color.
Boysenberry plants need a full sun location, with six to eight hours of sunshine per day. Plants prefer an organically-rich, well-draining soil, with a pH of 6.0-7.0. Keep the plants evenly moist but not soaked, giving them one to two inches of water every week.
Boysenberries are considered brambles, so they spread and expand. To keep the plants upright, tie them to the wires once they grow tall enough. The plants cling to the wire and expand outward along it.
Boysenberries grow best in moist soil. The moisture helps produce the boysenberry buds and berry development. When you water, make sure the water goes deep, but be careful not to overwater or flood your plants. Also, try not to get the leaves wet because that…
Boysenberries grow best in full sun and in well-draining, sandy loam soil. Ideal soil pH ranges from 5.8 to 6.5.
Boysenberries can be grown in most types of soil, but will be most productive in one that is fertile and moisture retentive. Unlike most fruit it doesn't have to be well drained. They will also grow in dry soils, but will fruit less profusely and…
Verticillium Wilt is a common fungal disease of tomato and squash family crops. It prefers warm (not hot) and wet conditions. This causes the tops to wilt in sunny afternoons, though they recover when it cools down (this often starts to happen when plants begin…
Boysenberries can be used for everything raspberries and blackberries are. Eaten fresh, sprinkled into yogurt, turned into smoothies, tossed into salads, added to salsa, blended into drinks, made into cocktails or wine, and even cooked down into sauces and purees to accompany meat and fowl…

Boysenberry Care As the plant matures, it will need support. A three-wire trellis or the like will do nicely. Keep the plants evenly moist, but not wet; water at the base of the plant rather than overhead to avoid leaf disease and fruit rot.
Boysenberries are a cross between blackberries, raspberries, and loganberries. They are fairly easy to grow and are well worth the reward! Boysenberry bushes can grow very tall and will require a trellis to help support the height.
Similar to other caneberries, boysenberries need fertilizer only during the springtime. Since boysenberries do not require large amounts of fertilizer, they do not really need fertilizer unless their growth is poor. However, they achieve the most consistent growth with annual springtime fertilization.
Transplanting Boysenberry Canes. Plant at the end of winter or start of spring. Boysenberries go into dormancy during the winter season, so right before they start new growth is the best time to transplant. Check the soil on occasion, and plant when the ground has…
