How to rejuvenate old ivy ground cover

Question

Have large part (about 4000 sq ft) of yard planted in Ivy ground cover, probably 45 years old (house built in ‘70s). Lotta old vines, but large patches with few leaves on bare stems. Old deciduous trees throughout, plus one large magnolia grandiflora and one large holly tree. How can I rejuvenate this ivy planting? Thinking about 10-10-10, but what other treatment might coax new growth out of those old stems?

Answer 1

The fertilizer would help, but it would really be beneficial to prune out any dead or bare vines. This will force new growth from those cut sites. Do this during the colder months, or at least when growth has slowed down.
