I have a few Boston Ivy plants that I planted in the spring of 2006 against a chain link fence. They have been in for 2 summers now and have not had much growth at all.....also, the one that grew the most I just noticed has been broken less than a foot from the ground. What can I do to stimulate these? Is it ok that they are almost cut to the ground at this point? I also have a few more that I put in last fall and would like any tips to care for these this spring/summer as well. I would like them to fill in my fence asap!!!
