How Do Blackberry Bushes Grow?
Blackberry bushes can grow upright in large multiple stemmed plants or low-laying vine plants known as brambles. Blackberry bushes can live up to 20 years according to published information from Oregon State University. Blackberry bushes growing upright do not need support; while brambles require a trellis to keep the stems upright. Keep the bushes watered, using 1 inch of water per week during the harvest season as recommended by the extension office of Oregon State University. Blackberry bushes can dry out quickly if they are not consistently watered.
