Vining plants need support such as cages, stakes or trellises. You can use black plastic mulch to increase the soil temperature, protect plant roots and help keep soil moisture. You may not need additional fertilizer applications, depending on how much organic matter you apply. Do not use fresh manure as it may contain harmful bacteria and increase weed problems. Improve your soil by adding composted manure or other compost in spring or fall. Spread the fertilizer in a six-inch wide band, and scratch it into the surface of the soil. Use the fertilizer at a rate of ½ cup of 46-0-0, or 1 cup of 27-3-3, or 3-½ cups 10-3-1 for every 100 feet of row. When the first fruits start to enlarge, apply fertilizer alongside the row of plants. Do not use any fertilizer containing a weed killer ("Weed and Feed"), as it may kill your vegetable plants. Too much nitrogen fertilization will lead to plants that are bushy, leafy, and slow to bear fruit. 
Unless your soil test report specifically recommends additional phosphorus, use a low- or no-phosphorus fertilizer.Many Minnesota soils have enough phosphorus. Apply phosphorus (P) and potassium (K) according to soil test recommendations.
