A thornless trailing blackberry cultivar, the plant grows up to 6 feet in height on a trellis and bears fruit 1 to 2 years after planting. \u003c\/p\u003e  \u003cp\u003eAn early mid-season variety, Rubus 'Columbia Giant' Blackberry produces high yields, higher than 'Marion' blackberries, of 10 to 15 pounds of very large, well-formed, attractive blackberries. The berries are giant—up to 3 inches long—and have a uniform conical shape. They are firm, juicy fruits with a well-balanced sweet flavor that has just a touch of tartness. The plant is hardy to -10 degrees Fahrenheit. \u003c\/p\u003e  \u003cp\u003eEasy to grow, Rubus 'Columbia Giant' Blackberry prefers full sun and moist, well-drained soil in a location protected from wind. Add organic content to enrich the soil; fertilize in early spring with an all-purpose fertilizer, such as 10-10-10 or a 16-16-8; and keep well-watered, mulching around the base to conserve moisture and kill weeds.  The plant is pest and disease resistant. \u003c\/p\u003e  \u003cp\u003eBlackberries are self-pollinating, so multiple plants are unnecessary for fruit production; however, planting two or more varieties with similar bloom times encourages cross-pollination, producing larger yields of larger berries. Planting early, mid-season, and late-fruiting varieties extends the blackberry season from early June to the end of the summer. \u003c\/p\u003e","brand":"parkseed","offers":[{"title":"Default Title","offer_id":42354526945339,"sku":"28802","price":23.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/8580\/4859\/files\/Product_MediaImage_28802_1.jpg?v=1753891758","url":"https:\/\/www.parkseed.mom\/products\/rubus-columbia-giant-blackberry-28802","provider":"Park Seed","version":"1.0","type":"link"}
