Do blackberry plants like pine mulch?

Yes, blackberry plants can benefit from pine mulch. Pine mulch helps retain moisture in the soil, suppress weeds, and regulate soil temperature, which can promote healthy growth. Additionally, as the pine mulch breaks down, it can provide some acidity to the soil, which blackberries generally prefer. However, it's important to ensure the mulch is not too thick to avoid retaining excess moisture that could lead to root rot.
