    I'm trying to cover a very large trellis (40'X40' or 50'X50', 10' high) with grape vines in a two-year period. The site is in western Massachusetts and receives full sun. I'm not sure how the soil drainage is, probably neither exceptionally dry nor wet (it's a large, flat field). It is on the border between zone 6a and 5b with temperature averages as low as 8 in January and as high as 81 in July.

    I recently called a local garden store and was advised that concord grapes would likely be able to accomplish this if they are planted 3' apart around the perimeter. The first question I have is, does this level of vigorousness match your experience? Generally, how many square feet can one expect a grapevine to cover given two summers of growth?

    Is there any pruning that ought to be done to maximize the leafiness? I've read much about pruning for fruit productiveness, but my immediate concern is that there be complete coverage. In future years I may concern myself with the yield, but for now I am focused entirely on getting a canopy of leafy vines.

    Are there any other recommendations you would make? What sort of fertilizer will best accomplish my goals? Should I purchase small plants from a garden store, or try to get cuttings from established vines?


    Thanks.

    Drainage is important - not many grapes like to have their feet wet for any length of time. Either have it assessed by a pro or your plants will let you of any shortcomings by dying.
    The pruning for maximum vegetative growth particularly on new plants simply consists of removing the flowers to direct the energy into the plant and roots rather than fruit. Developing a strong root system is what will give you growth potential in future years. Dormant prune after your first season, selecting the strongest cane to be the permanent cordon (trunk).
    Cuttings will be the slowest to establish; 1 or 2 year plants with well established and branched roots will save years on your project. No fertilizer at all is common for the first year, but get a soil or petiole analysis (by a lab that is familiar with grapes) to determine what you may need in the future.
