How to Mulch Raspberries & Blackberries


Raspberries and blackberries have a similar appearance and similar growth habits. Both raspberries and blackberries are perennial plants that produce berries on canes. Many blackberry varieties and all raspberry varieties grow best when you provide vertical supports for the canes along planting rows. Between the planting rows of both blackberries and raspberries, apply an ample layer of shredded mulch to prevent weeds from interfering in cane growth and keep the soil evenly moist.

Step 1

Apply the shredded mulch around the canes and between the rows in a thick layer to cover the entire soil area. Make the mulch layer between 2 and 4 inches thick.

Step 2

Keep the mulch from touching the canes directly by keeping the mulch layer approximately 2 inches away from the base of each cane.

Step 3

Replenish the mulch throughout the growing season to keep the thickness uniform. This will help keep weeds from growing and will help the soil stay evenly moist.

Step 4

Add additional mulch each spring at the beginning of the growing season to keep the mulch between 2 and 4 inches around the canes.
