How to Water Boysenberries

Boysenberries produce fruit similar in appearance to blackberries, but their flavor is typically more tart than a that of a blackberry. The boysenberry is a cross between blackberries and loganberries and all three plants require similar care to grow well and fruit abundantly. Boysenberries grow on a bramble as opposed to an upright bush. The plants prefer well-drained sites with full sun and won't tolerate or grow well in areas prone to standing water or muddy soil.

Mulch

Instructions

- 1
  Spread a 4-inch layer of straw or a similar organic mulch over the soil beneath the canopy of the boysenberry shrub. Replenish the mulch each year in spring or fall to maintain its depth. Mulch conserves moisture in the soil and provides additional organic matter to the bed as it decomposes.
- 2
  Water boysenberries when they begin flowering in late spring or early summer. Provide approximately 1 inch of water weekly. An inch of water typically moistens the top 8 inches of soil in the bed.
- 3
  Irrigate as frequently as necessary to maintain the moisture level in the bed in midsummer when the boysenberry shrub begins fruiting. The plants may require more frequent irrigation because of summer heat and drought during fruit set. Consistent moisture during fruiting improves the crop.
- 4
  Stop watering once the plant begins going dormant in early fall. Boysenberries don't require additional watering during the winter dormancy period.
