In late February or March, cut back to 2 strong sets of buds on each stem close to ground level. In spring, apply balanced fertilizer according to package directions. Check soil weekly for moisture, water thoroughly when dry. Place 2-3" of mulch around bottom of plant in spring to keep roots cool in summer. Increase mulch layer to 4-6" to protect the roots for the coming winter. Use on trellis or other structure suitable to support the vine; plant width is determined by the width of the trellis.
