Chester Blackberry Bush

Planting: We recommend spacing these plants 5 to 6 feet apart to allow ample room for growth. In rows, plant them 2 to 3 feet apart with rows spaced 3 to 5 feet apart in well-tilled, weed-free soil. 

To plant, place in an area of full sunlight (6-8 hours daily) and dig a hole that is at least 6 inches wider and the same depth as the root mass. The crown or graft of the plant should be slightly above ground level, as it was positioned in our nursery. Trim off any broken roots and branches before planting. 

Spread the roots in the hole and fill it halfway with soil. Then, water the area until the soil settles and becomes thoroughly saturated. Re-adjust the plant if necessary and fill the hole with the remaining soil. Finally, backfill with the rest of the soil and water well.

Watering: If summer brings one to one and a half inches of rainfall each week, you won’t need to use the hose. However, during dry spells, give your new plant a thorough soaking by letting your garden hose trickle slowly, which allows for better absorption. A soaker hose can also water multiple plants at once.

Keep newly planted crowns watered and ensure the soil remains moist throughout the growing season. To check if your plant needs water, touch the soil around the roots. If the soil is dry, soak it using the hose end without a nozzle, avoiding the leaves. For an accurate soil check, insert your finger about three inches deep.

Fertilizer: Chester Thornless Blackberries generally do not require heavy fertilization once they are established. For new plantings, apply a balanced fertilizer, such as 10-10-10, at a rate of about 5 pounds per 100 linear feet of row. For established plants, fertilize in early spring and again after the harvest. However, be careful not to over-fertilize, as this can lead to excessive vegetative growth at the expense of fruit production. Conducting a soil test can help you determine the specific nutrient needs of your plants.

Pruning: After planting, prune bare-root canes back to about 2 inches above the ground to encourage new growth. Once your raspberry plants have grown sufficiently (which may be after their first year), prune them in early spring as new growth appears.

For young canes, trim them to a height of 4 to 5 feet to prevent overgrowth and improve fruit quality. Remove all weak, dead, damaged, or diseased canes, and as your plants mature, leave only about 8 to 10 of the strongest canes.

Weed Control: The best method of removing weeds and suckers from around your blackberry bushes is to get a firm grasp on them and pull them upwards out of the ground in a twisting motion. Placing a 3 inch thick layer of mulch around your bushes to prevent weeds from growing. Mulch will also help the soil retain moisture.

Pests and Diseases: Some of the most common pests for blackberry shrubs include spider mites and birds. To rid of bugs like mites or worms, spray your bush with an all-natural organic pesticide. Birds can be trickier to get rid of. Place fake owls or snakes around the bushes to scare them, or cover your bushes with bird netting.

Common diseases for blackberries include different types of mold and fungi. These can be prevented by removing dead or damaged branches. Doing so will prevent chances for infections and the spread of pathogens. If you see any spotted leaves or branches, remove them. Molds and fungi can be treated with the use of organic fungicides.

Pollination: This variety is self-pollinating. While it's optional to plant pollinating partners for larger crops, doing so can enhance the yield. You'll still get fruit from just one plant.
