|My wisteria finally bloomed this year after I stopped fertilizing the surrounding lawn (too much nitrogen). It was gorgeous for a month and now that blooms are gone, the leaves seem weak and are a light yellow-green. Over watering is not the culprit as it only gets water once every 10 days or so. It is 4 years old and climbs 8 feet up a patio cover. How do I improve the foliage health & color now?

|Why not try a foliar fertilizer? Use Miracle Gro or Miracid and spray only on the foliage but not on the roots. This will feed the leaves but not build up in the soil.
