Lilacs

Question

It seems that the blooms on our lilac bushes are losing their purple color and are more whitish. Is there anything they are lacking that I could do so the blooms are darker?

Answer 1

Flower color may lighten as the flowers age.
There is not way to change the color of a lilac.
Keeping your plant healthy with care and pruning is the best way to keep flowers bright.
