Space the horizontal wires 45cm (18in) apart, with the lowest wire 30–45cm (1–1½ft) from the ground. Most blackberries and hybrid/species berries produce their fruit on stems (or canes) that grew the previous spring and summer. Old stems need to be pruned out and new ones trained onto the supports:

The best way to water blackberry plants is to only water when the top 2-4 inches of soil is dry. I check this by pushing a finger into the soil. By watering in this way, we’re preventing both under and over-watering.
Blackberry plants that are too hot and dry get wilting leaves as the moisture is leaving the leaf faster than the roots can supply it. And if the roots don’t have sufficient moisture, the leaves can curl, curl, brown, and drop in a matter of days or hours. Ideally, grow blackberry plants in USDA zones 4-10, depending on the variety. This is general...
If your blackberry plant was recently planted or repotted, and its leaves are wilting or drooping, it’s likely due to transplant shock. Transplant shock occurs when a plant is exposed to a new environment and has to establish a new root system. Avoid transplanting blackberry plants unless necessary as it can take up to 1 year for recovery. To help ...
Verticillium Wilt
Verticillium wilt is a fungus that is similar to root rot in that it usually occurs in soils with excess water.Additionally, over-fertilizing can also cause it. The most susceptible fruit crops that contract verticillium wilt are nightshade (tomatoes, peppers, and eggplants), but other fruiting plants such as blackberry plants can also be infected. Symptoms of this disease include leaves wilting, yellowing, and dropping, and potentially branch dieback. Prevent and treat verticillium wilt by p...
Fusarium Wilt
Fusarium Wilt is a plant disease caused by the soil-borne fungus Fusarium oxysporum. This pathogen can infect a wide variety of plants, including blackberry plants, leading to wilting, yellowing, and ultimately plant death. The fungus enters the plant’s vascular system, obstructing the flow of water and nutrients, which results in the wilting symptoms.
Jan 30, 2023 · Here’s how to do a percolation test: Dig a 1-foot by 1-foot hole. Place a yardstick in the hole and fill it with water. Wait an hour and measure how far the water has drained. Ideally, soil drainage should be around 2 inches per hour. But this is a guideline and not a rule, so don’t worry if yours is way off.
Jun 28, 2023 · Begin the removal process by cutting the blackberry bushes back to ground level using pruning shears or loppers. This will make it easier to access the roots and prevent further growth. Remove all the cuttings from the area to prevent re-sprouting and dispose of them properly. Step 4: Digging out the Roots.
- Improper Watering. Under-Watering. Under-watering blackberry bushes cause their roots to dry and die, which limits the amount of moisture the plant can send to its leaves.
- Improper Nutrients. Either too much or too little nutrients cause blackberry plants to get brown leaves. Excess nutrients chemically burn the plant’s roots, causing the plant to die off.
- Transplant Shock. If your blackberry bush was recently planted or repotted, and its leaves are starting to curl, yellow, or brown, it’s likely due to transplant shock.
- Diseases. Root Rot. Root rot, also called Armillaria or Phytophthora Root & Crown Rot, is a root fungus that causes a blackberry bush’s leaves, blossoms, and fruit to droop, yellow, brown, and drop.
Mar 15, 2024 · Planting Depth and Technique: Plant blackberries at the same depth they were grown in the nursery. If you’re using bare-root plants, soak the roots in water for 1-2 hours before planting. Spread the roots out in the planting hole and cover them with soil. Gently tamp down the soil and water the plants thoroughly.

The best time to establish your bed and build a trellis is in the fall before you plant. If you have multiple bushes, you can build a wire trellis by placing 4-foot tall, 4-inch square posts every 12 feet. Run several wires between the posts. The wire should be placed at 2, 3, 4, and 5 feet from the ground level.
