Fertilizing Hybrid Berry Plants

Until harvest season, boysenberries require little in the way of fertilizer. Then in late spring, begin a weekly feeding of half-strength liquid plant food just prior to berry formation. Suspend feeding when berry production stops.

NOTE: This is part 6 in a series of 11 articles. For a complete background on how to grow hybrid berry plants, we recommend starting from the beginning.

In early spring, use 3 inches of compost or fertilize with bonemeal to strengthen your tayberry’s roots and stimulate increased fruit production.

Fertilize each spring with our Blackberry & Bramble Fertilizer.
