I have Miss Kim lilacs that have been established for 6 years. Each year they bloom less and less.

I have heard that trimming at the wrong time of year may effect next year's flowers. Is that true?

They have plenty of sunny, I treat them with acid and they get enough water. They are very healthy, yet the flowering keeps decreasing.

All help and suggestions are VERY welcome.

These plants need full sun all day long to bloom their best, along with adequate soil and water. Sometimes neighboring trees grow over time and increase shade over the lilacs. Pruning should only be done immediately after they bloom in the spring. These shrubs bloom on old wood grown the previous year and so pruning later in the growing season could reduce blooms the next year. Oversupplying them with nitrogen could also possibly cause them to grow excessive foliage at the expense of blooms.
